Psychopathic Manchild

Johnny's wacky like that.

"Like I said, kids are cruel, Jack. And I'm very in touch with my inner child."
— Sundowner, Metal Gear Rising: Revengeance

A dangerous villain or a brutal Anti-Hero, either a teenager or an adult, with a childlike nature, which creates a dissonance between innocence and savagery. Such characters can become rich sources of Nightmare Fuel, especially if their childishness is never explained. Contrary to the term, many examples are not necessarily psychopaths in the clinical sense. Misaimed Fandom may not be out of the question, either; sometimes the character's more "Moe" attributes will be picked up on and subjected to Flanderization.

The exact extent of the character's childishness will vary, and in general Psychopathic Manchildren can come in several varieties, with possible overlap. Such a character may:

  • Be big Dumb Muscle, frequently mentally-challenged, that operates under someone else's direction. This type may be the most common, and also the most likely to play to the audience's sympathy. Expect him/her to try to Pet the Dog, often with disastrous results. Could be a subversion of Dumb Is Good.
  • Seem superficially powerful and cruel, but have very childish or simplistic goals, motivations or world views. May overlap with One of the Kids—if the cruelty part isn't played up to horrifying levels.
  • Actually possess a lot of power, intelligence, and/or prestige, but also have some childish qualities or behaviors, to fit in with a certain aspect of the story being told, or else advertise that there is something seriously wrong with him/her, to make him/her creepier. These are most likely to be a story's Big Bad.
  • This one is a literal example: Appear cute and harmless on the surface, but actually be this trope. Especially common with female examples, because of the stereotype.
  • Be subject to a personal variation of Values Dissonance where violent, savage actions are viewed by the character in question in the same light as regular play is viewed by most real children. This variant is often an especially strong source of Nightmare Fuel due to the uncanny dissonance between his/her childish demeanor and the viciousness of his/her actions.
  • Be completely or largely inexplicable, and the discrepancy between the different parts of their personality Played for Laughs.

What makes this character stand out is that he is The Sociopath in that he is mostly incapable of feeling empathy, shame or remorse but unlike other sociopaths, his mental immaturity prevents him from imitating emotions or indeed even realising why he should. He takes his desires for granted and fails to even superficially consider why others would disagree or why he isn't entitled to everything. Type C is excepted from this, of course. Whichever version these types of characters qualify as, often they are not fully aware of how nasty their actions actually are. In some cases (though not all), a Heel Realization may cause the character to develop into a better person. A more innocent or well-intentioned Psychopathic Manchild may be a Noble Demon.

One way to use this character is to face him off against a jaded, cynical, or shady Anti-Hero, to play with traditional hero-villain relationships by making the villain more innocent than the hero (at least in theory). (Easier if he's a major villain in his own right.) Another interesting twist is to make this character the Designated Hero and match him with an Affably Evil villain.

When one of these is running a country or occupying a similar position of authority, you have The Caligula.

The grown-up equivalent of Creepy Child and the near-inversion of Enfante Terrible. Contrast with Sociopathic Hero and the typically more benign Man Child. See also Cute and Psycho and Ping-Pong Naïveté. Related to, but distinct from, Kids Are Cruel.

     Anime and Manga 
  • Kaminashi from Choujin Sensen turned out to be quite the delusional lunatic who believes that he brings salvation to good-natured women by killing them, thus "saving" them in a world he perceives as corrupted and rotten. The fact that he still believes he's innocent is even more disturbing considering how he murdered 5 female victims (including a 3 year old girl) within half a year.
  • Johan Liebert of Monster is a classic example. His goals and desires are highly simplistic but as an adult he pursues them with an appropriate level of sophistication. Exactly how childish he really is can be hard to judge given that he's an excellent manipulator.
  • Tongpu from the Cowboy Bebop episode "Pierrot Le Fou" is an unstoppable killing machine who is terrified of cats and reveals his childlike nature upon being wounded by Spike. Exposition explains earlier on that this mad, efficient killer was the result of experiments to turn him into what he is today, but the experiments had the unintended side effect of regressing his mind, and Jet remarks (paraphrasing Freud) that "there is nothing so pure and cruel as a child". His reaction to Spike's attack is the first time we truly grasp just how far back he's gone.
  • Claymore:
    • Miata is little more than a child (who actually breastfeeds from Clarice to stay calm) though several other fighters don't realize this, what with her ungodly ability to kill masses of Yoma at a time. And, if necessary, with her bare hands.
    • Priscilla may count too, at least until she awakens.
  • The Devil Is a Part-Timer!: In his first appearance, Lucifer reveled in the screams he caused and treated the fight with Maou and Emi as a big game as he destroyed everything around him.
  • Gluttony from Fullmetal Alchemist is a ridiculously strong Artificial Human with the temperament and intelligence of a young boy. Throughout most of the series, he's reliant on his "keeper" Lust to do the thinking for him (his main input being to ask her if he can eat people). When she dies, the poor guy suffers a nervous breakdown.
  • King Hamdo from Now and Then, Here and There is a power hungry ruler (with more than a passing resemblance to certain African dictators) who throws tantrums and calls for his assistant Abelia to comfort him when things go wrong. He thinks little of human life and often laughs maniacally.
  • Mao from Code Geass, whose child-like attitude is slightly justified by the fact that he was orphaned at a young age and never received anything even resembling a traditional upbringing. That does not justify the wanton More Than Mind Control he engages in...
    • It's even more obvious in the supplemental reading, in which he is, in a word, so innocent that he manipulates and kills people with evil impulses to stop them from hurting his beloved C.C..
    • Also, due to the young age at which C.C. gave him the Geass and the fact that it evolved at such a young age too, he's never really matured, or had a chance to.
  • Nova, Hikaru's Enemy Without from Magic Knight Rayearth's second season. She just wants to be loved by Hikaru...and by that, we mean cover her friends in large pools of blood so that only the two of them can "play" forever and ever.
  • Axis Powers Hetalia:
  • Dark Action Girl Nena Trinity from Mobile Suit Gundam 00 is an excellent Type D. She's pretty, spoiled, cheerful, friendly, mock-fights with her brothers, will happily invade your personal space and kiss you if she thinks you're cute, has a really funny mascot in the form of her purple Haro... but after being raised as a Tykebomb Artificial Human with no concept of morality, she will bomb your house if she's got to work while you have fun at weddings. And then she'll be all "Whoopsie! :3" when asked why did she do that.
    • In the side materials, it's strongly implied that there's a pretty good reason for this: seventeen-year-old Nena was kept in stasis almost from birth... and only woke up around seven years before the series starts. As such, her mental psyche isn't the same age as her physical body. She's a little girl in the body of a teenager; such stuff does a LOT in the mental/emotional maturity of anyone.
    • Wong Yunfat from Mobile Fighter G Gundam is one of the rare Magnificent Bastard versions, as well as a Type C. He loves eating chocolate and is seen in his pajamas as well as leaning on a giant teddybear at one point, and some of his reactions to being in a disadvantage can be seen as very childish... but Wong's own cunning plans and back-up plans make him far smarter and more ruthless than the average PSM.
    • Rosamia Badam from Mobile Suit Zeta Gundam. She's a Type D as well, but in different terms: she's a 17-going-to-18 year old Dark Action Girl who, outside her mecha, has the mentality and the fears of a little girl, latches innocently on whoever she sees as a Replacement Goldfish for her dead older brother, and is borderline unable to take care of herself in a normal environment. In her case, it's very justified: Rosamia not only is a survivor of the infamous Zeon Colony Drop of the One Year War, which happened when she was a little girl, but was subjected to cruel experiments that messed up with her mind even more.
    • Mobile Suit Gundam SEED has Muruta Azrael, a psychopathic genocidal maniac, motivated by childhood grudges, and possessing the maturity level of a particularly vicious teenager.
    • Mobile Suit Gundam SEED Destiny has Rosamia's even more handicapped expy, Stella Loussier, who while very efficient in combat, is a five year old outside of her mecha, sometimes screaming about how the "scary things" are coming for her, and flipping out in sobbing meltdowns at the mere mention of death. Her teammate and sort-of brother Auel Neider is only marginally saner, and while he can sort-of handle Stellar (as in, attacks anyone who tries to approach her) can be driven into a breakdown by the mention of his mother.
    • Mobile Suit Gundam AGE has a Type B in the grown-up Desil Galette. To put it in perspective: he was introduced in the first part as an Enfante Terrible, and in the second part he may be in his 30's but he hasn't actually changed his attitude and doesn't even really plan to.
  • Renge in the Flame of Recca manga, who is so childishly nuts she tore up a Teddy Bear just because it doesn't answer her when it doesn't have a speaking device, only to cheerfully laugh to ask for her Papa to get her a new one. Speaking of her Papa, Mori Kouran, she thinks her Papa's horrendous monstrous look after fusing with Tendou Jigoku looks EXTREMELY COOL. She doesn't end really well.
  • Bambi from Bambi and Her Pink Gun is incredible childish in many ways, but also subverts this in others. While she's a psychopath who acts almost entirely on instinct, she's also a vain health nut who doesn't eat anything she hasn't personally boiled and will kill you if you so much as smoke near her.
  • Dragon Ball:
    • Emperor Pilaf acts like a Spoiled Brat and throws temper tantrums when he doesn't get his way.
    • General Blue technically qualifies. Although he has other reasons for disliking Bulma, his exact reaction regarding Bulma's attempts at seducing him is extremely similar to a little kid not wanting to interact with the opposite gender due to a fear of cooties.
    • Vegeta before his Character Development is completed. His determination to surpass Goku and constant bragging about how he's the Prince of all Saiyans sounds like a petulant spoiled brat throwing a tantrum because no one's kissing his ass. Especially in the Buu Saga: while fighting Goku as Majin Vegeta, he goes off on a big rant over how Goku's existence is insulting to him because even Goku's son was stronger than him at some point.
    • His fellow Saiyan, Nappa, doesn't fall too far behind. He fights by basically playing with his prey and has a tantrum when Goku beats him up.
    • Everyone in the Ginyu Force is this to one or another extent; Recoome is just the most blatant example. These are the ruthless elite soldiers of Frieza who also love to make very hammy Sentai poses to introduce themselves to friend and foe alike and decide things via rock/paper/scissors.
    • Even Frieza gets to have traits of this. Usually behaves in a manner similar to that of a spoiled child. He often behaves like a Spoiled Brat despite being at least 70 years old. This is shown in Resurrection 'F', where he whines and throws a temper tantrum that involves punching small craters into the ground when Vegeta beats him out of his Golden Super Mode. Another notable example is when he comments in hell about Goku fighting with Kid Buu.
    Frieza: Stupid little Saiyan monkey! *blows raspberry*
    • Android #17 is Type B, treating the hunt for Goku like a game and deliberately going the roundabout way of finding him for fun. Even more so (in fact a cross between B and E) in the Bad Future of Future Trunks' timeline, where his sister is one of these also to the point 'go on murderous rampage' is her default response to not getting what she wants; in fact, they spent twenty years going on random killing sprees and keeping score of the kills. When Future Trunks shows up and she wants to kill him to blow off steam, #17 agrees to let her do so, but remarks they'll be throwing away weeks of playtime if she does, treating it more like a game than their nemesis. Trunks actually calls him out on it before killing him.
    • In his second form, Cell whines and throws a temper-tantrum because Vegeta won't let him absorb Android 18 and reach his Perfect Form. After being forcibly reverted to this form by SS2 Gohan, his response is to throw a massive fit and to try to blow himself up, taking the Earth with him.
    • Babidi, despite being hundreds of years old, acts like a Spoiled Brat. He is prone to throwing tantrums, whining, and bullying others when things don't go his way. He also treats hurting and killing people like some kind of game, laughing in delight when Buu ate cities or when his former loyal servant Dabura was beaten senseless and devoured.
    • Fat Majin Buu from Dragon Ball Z is Type A - he has no idea that what he's doing is wrong, and is single-handedly converted to good by Hercule / Mr Satan. Super Buu is type C; he sounds increasingly intelligent once he starts absorbing people, but still throws tantrums when he's outmatched. Kid Buu, who doesn't have any desires that don't involve blowing things up, is Types C and E put together.
    • Broly is somewhere between Type B and Type C, arguably. His motivation to kill Goku? Goku's nonstop crying scared him and kept him awake for days on end when they were babies in the same "nursery." The English version plays this up with his Kiai, which sounds less like a Kiai and more like he's throwing a tantrum.
    • Chilled from the Gainax manga Episode of Bardock presumably qualifies under this trope, as he has shown himself to be exceedingly childish, and yet was shown to be even more ruthless than even Frieza, notably killing one of his soldiers while in a good mood just because the soldier was unfortunate enough to just happen to be blocking his view.
    • Beerus, the Big Bad of Dragon Ball Z: Battle of Gods. While incredibly powerful, to the extent that he can curb-stomp Super Saiyan 3 Goku with one finger, his attendant Whis has to remind him to brush his teeth and eat his vegetables. He's also prone to losing his temper and responding violently to petty things: for example, he blew up King Kai's original planet simply because King Kai beat him at a video game, and also threatened to blow up the Earth purely because he was pissed that Majin Buu ate all the pudding at Bulma's birthday party after Beerus explicitly asked him to share. Dragon Ball Super continues with this as, when he's told that traveling to Earth would take about 26 minutes, he complains that he could watch an anime in that time.
    • Beerus' twin brother, Champa, hovers between this and Man Child. On one hand, he's more mellow than Beerus since he doesn't have a bunch of Berserk Buttons and not as prone to Disproportionate Retributions. He's even willing to share food, where Beerus nearly blows up the Earth over pudding. Then he tries to murder his entire team from Universe 6 for the 'crime' of losing against Universe 7 during the tournament.
  • Misa Amane from Death Note is Type D- an endearingly naive Kawaiiko who has a very childish demeanor that persists well into her 20s, obsesses over fashion like any young girl, is completely boy-crazy, and was able to translate her Moe appeal into a successful career as an actress/model. All this is likely because her parents were murdered while she was still a child, trapping her in a perpetually immature state. Unfortunately for the world, this apparently happened before the Amanes had the chance to explain to their daughter that human life has an intrinsic value beyond being useful to Misamisa-chan, who latched on the man who used his Death Note to kill the burglar years after the actions that shattered Misamisa's mind. The results weren't pretty.
    • It's possible that she was just a nice, cute, but immature young woman at least partially driven insane by the Death Note. Given Light Yagami's flying leap off the slippery slope from an idealistic young man who thought he was doing the right thing to a maniacal tyrant willing to kill anyone and anything to further his raging god complex and Teru Mikami's astonishingly short break from a focused, serious lawyer with an inhumanly high standard of justice to a barely coherent Ax-Crazy psychopath, it's not too hard to imagine that the Death Note has an unspoken With Great Power Comes Great Insanity rule that Misa was affected by. For example after she permanently gives up the Death Note, she's completely harmless and probably quite fun to be around, unless you're Takada.
    • Light himself qualifies as Type C (flirting with D). When L details the psychology of Kira to the police, one of them suggests that they could stop him by no longer publishing the name of convicts in the news, as he clearly was getting the names of his victims from the media. L states that won't work because Kira will then simply start killing people he thinks are guilty and will further blame the police for any innocent people he kills, specifically identifying his childlike personality as the reason for this. Sure enough, Light does display lots of childlike evil throughout the series, such as killing the fake L for insulting him on national television and his need to gloat to L and Near when he thinks he's beaten them. His Villainous Breakdown at the end takes the form of a blatant temper tantrum.
    • Ryuk is type B-a cruel monster who sets everything off because he's bored.
    • Mello also fits this trope (type B and C). Although very smart and willing to actually do something, he cares far more about besting Near than he does about bringing Kira to justice, and is prone to violence. He also eats a lot of chocolate.
    • In the Light Novel Another Note, Beyond Birthday is type B, with some attributes of Type C. He also flirts with Type E.
  • Umineko: When They Cry: the Stakes of Purgatory seem to have some elements of this. Oh no, their new toy broke...
    • Depending on how you interpret the series, you could probably include Beatrice, Eva-Beatrice, and Erika in this trope. All the witches except (maybe) Virgilia are prone to Immortal Immaturity, though in Lambdadelta's case her childish behaviour is just an act, and Beatrice is later revealed to be only 19 years old and not a thousand as she claims. Though when you take her upbringing as Yasu into account, you can't exactly blame her. Maria gets excused because, well, she is a little girl.
  • Wonderweiss Margela from Bleach fits pretty well. He can't even speak coherently, but heaven help you if you don't let him play with your hat or aren't Yamamoto. Technically he's a Type A - under Aizen's full control, appears to have limited understanding of his actions, will attack Aizen's opponents, but seemingly at random with no real indication he's enjoying the violence as such.
  • Domu: A Child's Dream, one of Katsuhiro Otomo's lesser-known works, features Old Cho, a powerfully psychic but senile old man whose primary source of amusement happens to be wreaking mischief on his fellow tenants in a large apartment complex. Unfortunately, he also has a mean streak a mile wide, so his pranks are often lethal - and if he's denied his fun, he's prone to throwing tantrums. You do not want to be present when this happens. Fittingly, the one who actually defeats Old Cho is Etsuko, a Little Miss Badass with similar psychic powers and a Plucky Girl nature.
  • Ladd Russo of Baccano! can get pretty child-like in his homicidal glee, and is usually shown skipping, babbling excitedly, dancing in pools of blood, or any combination of the three.
    • In the light novels Chick and Maria are described as having the personalities of 12-year-olds. Speaking of, Chick qualifies in the anime as well.
    • Ladd's Loony Fan Graham Specter may also count.
  • Kano from Texhnolyze. He's eloquent, intelligent and charismatic, but that doesn't change the fact that he sees the world as a one big playground, and himself as the only real person in it.
  • Diva from Blood+ is a very depraved type B. For example, in episode 24, she bites young Riku and drinks his blood, then childishly laughs and jumps around in a white and blue Pimped-Out Dress when caught by the heroes, before she captures Saya herself and almost kills her. Later, she will rape and kill Riku to impregnate herself.
  • Friend from 20th Century Boys is a rare Magnificent Bastard version of this. As clever as he is, it doesn't change the fact that he is only trying to destroy the world because he never grew out of his childhood grudges.
  • Machina of Hayate the Combat Butler. He nearly kills Hayate, even stating it wouldn't be murder, and later on he turns into a giant snake. He also Gets very excited when his master gives him money to get something to eat and orders 100 hamburgers all at once.
    • The main character's parents, with heavy emphasis on manchild.
  • Pegasus J. Crawford / Maximillion Pegasus from Yu-Gi-Oh!. He steals people's souls (including a small child's), tries to take over a company by killing the CEO and pursues Ancient Egyptian artifacts with no regard for anyone in his way, all to bring his wife Back from the Dead. In his spare time he watches cartoons and loves them to the point that he creates a DECK based around them. In the anime, he becomes a good guy later on, though. (Ether type C or type B)
  • Lucy from Elfen Lied is a mixture of types C, D (counting Nyu), and E.
    • The silpelits can also qualify even though they're chronologically children because they age quicker.
  • In One Piece, Monkey D. Luffy is your typical Shōnen childish Idiot Hero. So what happens when you remove his shadow and create a hundred-foot-tall monstrosity with it, using the body of an ancient demon warrior? Oars has all of Luffy's idiocy, childlike naivety, and personality, with none of the tempering kindness and concern for friends.
    • The Demon Guards of Impel Down, four bizarre Zoan users seem more animal then man but like to goof on each other and cower whenever their officer Sadi-chan is angry like them like children to an angry mom. They are also extremely sadistic, and love the brutalize prisoners.
    • One of the newest members of the Blackbeard Pirates San Juan Wolf seems to apply. In his past, he was a Pirate who committed crimes "so atrocious they were effectively erased from history itself", a bounty likely to be in the upper multi-millions, and when caught offscreen, was transferred to the lowest level of Impel Down, and to earn his freedom from there, was forced to kill everyone in his cell on orders from Marshall D. Teach and co. Also, he is the largest man alive in the show, easily dwarfing Oars at least four time over, and is compared to a walking Sears Tower. But, in his first appearance, he peeks out from Marineford HQ's main building like a curious child, has an expression like he was caught stealing from a cookie jar when spotted by Mooks, expressed surprise that a Vice Admiral knew his name, and was scared by Whitebeard and hid while the rest killed him.
      • His classic "They found me!" line , which is all the more hilarious when one looks at this size comparison pic◊, yes the circled person is one of the regular giants.
    • Later chapters in the Dressrosa arc reveal Doflamingo to be this. His despicable nature and cruelty, along with his desire to "destroy this world" are simply him being the Spoiled Brat he was as a kid and throwing a temper tantrum over the fact that he didn't get what he wanted, being denied his "rights" as a descendant of the twenty kings who found the World Government by the other World Nobles because his father happened to be one of the few sane people in Mariejois and left the city with his family to live the commoner life. Despite all his rants about being an adult who doesn't have time to play Luffy and Law's "kiddy games," it's blatantly obvious that despite being so world-weary, he hasn't really matured at all from when he was a kid.
  • Rip van Winkle from Hellsing is an excitable young woman who likes to sing opera beautifully and also enjoys killing things while laughing her ass off. She intends on conquering the world for Millennium.
  • Vincent Nightray from Pandora Hearts might as well be the king of this trope due to his nasty habit or slicing up dolls with scissors and causing the tragedy of Sabrie. There's also the Will of the Abyss, a whimsical and childlike being that rules over the hellish alternate reality of the Abyss. She veers wildly between moods, acting like an innocent little girl one moment and casually plucking a man's eye out the next moment. It's because she once shattered her own mind and memories to protect her sister and Oz, leaving her completely insane.
  • Jack Winslow of Power Stone is a really 100-year-old crazy who was orphaned at a young age and lost at sea. Lack of human contact might explain his behaviour.
  • Chrono Crusade has Joshua Christopher, who was kidnapped by the Big Bad as a young boy and given powers that turn him insane. Although he's 15 in the main bulk of the story, he still sometimes acts like the child he was when he was kidnapped, treating attacking a girl as a "game" and pouting about pudding being ruined right before slaughtering the demons responsible. The anime version emphasizes the "childlike" side, including the ending having him lose all of his memories and reverting back to the personality he had as a kid, while the manga makes him more mature and aware but possibly more insane.
    • The anime also seems to treat Shader this way, by keeping her Genki Girl personality but changing her morality from a grey shade to nearly completely black, giving her a sadistic streak to boot.
  • Sojirou from Rurouni Kenshin. At least until his Heel–Face Turn, when his whole personality acquires something of a shift....
  • Puppetmon from Digimon, anyone? He kidnaps Takeru in order to play hide and seek. While trying to kill his brother Yamato and the rest of his friends, and then Takeru himself. Way to go.
    • Arguably Diablomon from Our War Games. There isn't much known about it, but consider that the e-mails it sends suggests that it sees the battle as a game, and that the only sound it makes (in the original version) is a creepy childish giggle.
    • Yukio Oikawa from 02 is a more sympathetic example, never really maturing after he discovered the Digital World and especially after his best friend died. He finally starts growing up after he meets the father and son of his late best friend again and realizes that they must miss him even more than he does. Sadly, it doesn't matter since he's been possessed by Myotismon.
  • Izaya of Durarara!!. One of the rare Manipulative Bastard versions. It becomes quite obvious as the series progresses that he sees everyone and everything around him as little more than toys to be played with until they break.
  • Eva-R and Eva-Q in Seikon No Qwaser are conscious of and delighted with being playthings, meant to suffer and die for Eva Silver. And yet in a backwards way, they regard any prospective dominant (i.e., anyone they look at) as their plaything, and are quick to break any 'toy' who isn't breaking them to their satisfaction.
  • Naruto has a mixture of villains who act mature and others who act like kids, though to be fair the same is true of the heroes.
    • Tobi aka Obito is a Type B. Depending on the viewpoint, his goal is either childish or overly idealistic:He wants to replace reality with a dream where everyone can be happy and the good guys always win. The psychopathic part comes from the fact that he is willing to kill lots of people to accomplish this, as he reasons that they will be resurrected anyway once he accomplishes his goal.
    • Madara Uchiha, Type C: Incredibly powerful? Check. Head of his clan? Check. Co-founder of the Hidden Leaf, and, by extent, the shinobi village system? Check. So why does this trope apply? The over-arching plot is a temper-tantrum he throws after eavesdropping on Hashirama and Tobirama Senju, in their own home, and hearing Tobirama express his opinion that the title of Hokage should be voted on by the Village Elders and Clan Heads instead of just being handed to Madara because Hashirama wants him to have it. Ironically, Madara probably could have been voted Hokage if he didn't have a history of behaving this way. Also, he is extremely cocky.
      • He acts like a child with a new toy when it comes to the Juubi, as well as when he's fighting Eighth Gate!Gai. Obito calls him out on his behavior with the former!
  • Gates from Full Metal Panic! is an over-emotional Cloudcuckoolander who acts rather like a child throwing temper-tamtrums, and whose completely random actions would be hilarious if they didn't involve killing so many people.
  • The villain from the second episode of Pumpkin Scissors shows signs of this, in that he kills the people in his charge as part of a fun game, and is hinted to be capricious to the people in his court.
  • Chaka from Black Lagoon is introduced as a Type B. He seems like a dimwitted yet likeable mook who harbors an almost childlike enthusiasm for guns and shootouts... then said facade falls down, and we're faced with Ax-Crazy. Who's also Too Dumb to Live, as Ginji eagerly proves.
  • Ni Jianyi's pupil who is only known as Kami-sama in Saiyuki is a sadist who loves to toy with people while pleasantly torturing them (evident by "helping" Goku get rid of a pendant ball embedded in his leg). When the Sanzo group stormed his castle, he played games with them as if they were in an amusement park. They eventually found him in his room surrounded by stuffed animals which were actually the souls of people he had stolen. And once he started to lose, he threw a temper tantrum.
  • Tamaki, the Promoter of Deadman Wonderland. When he isn't causing the deaths of or torturing inmates he's often found playing with toys in his office, including a Lego model of the prison and a dancing flower. He's also a bit of an RPG Otaku and sees the Wretched Egg as a Big Bad to defeat.
    • And the reason for the prison to exist on the first place? He was a bum man-child living of his mother when wretched egg caused an earthquake that destroyed his computer along his game data!
    • There's also Mockingbird. He was by all accounts downright terrifying in battle and is one of the most powerful and feared Deadmen in the series this side of Wretched Egg, but outside of the ring, he was childish, playful, and didn't seem to take anything seriously except for his Morality Pet. Turned Up to Eleven when it comes to Hagire, who Body Surfed into him.
  • Kirika Kure of Puella Magi Oriko Magica is completely unfamiliar with the concept of maturity. Among other things, she throws tantrums at a moment's notice and drinks her tea with enough sugar to make it into syrup. She's also hunting down and killing other magical girls. Although her motive for doing so is because she was asked to by Oriko, whom she is obsessively in love with, rather than her childish tendencies. (Then again, killing others because Oriko tells her so could be seen as childish too, as she does so to please said person and get praise from them than of her own will.)
  • The Big O's Alex Rosewater. "This is my Big! This is my dome! You can't have it!" Also, to an extent, Alan Gabriel.
  • Haruko from FLCL.
  • Amaimon of Blue Exorcist is a demon king who displays childish Cloudcuckoolander tendencies, uses his visits to the human realm mainly for sightseeing, and is extremely fond of candy. He's also excited by the thought of killing people and treats fighting like some sort of "fun" game.
  • Michio Yuki, the Villain Protagonist of MW, is either type C or D.
  • Akihiko Kayaba of Sword Art Online trapped thousands of people in a virtual world of his own making with no way to log out other than to clear the game, walked among them as a player and rallied several of them around himself in one of its most powerful guilds, with full intention of betraying them as the games Final Boss, and made it so that anyone who died in the game was Killed Off for Real. In his final conversation with Kirito and Asuna, he reveals that he did this all so that the imaginary play world that he always dreamed of would be as real as he could possibly make it. He also seems to be oblivious to the moral and ethical implications of his actions. To the point where the fact that he is responsible for the deaths of 4,000 people, is simply an abstract statistic to him.
  • Akura-Ou from Kamisama Kiss. One minute he is playful, happy and silly... the next minute he will brutally kill dozens of people for the most trivial of reasons.
  • Some fans of the Japanese version of Mewtwo from Pokémon: The First Movie have likened it to a scared, confused and angry child, placing it in types B and C of the trope. Its motives amount to a psychic powered temper-tantrum as a result of its mistreatment and some of its dialog is childish in some aspects, saying "Don't tell me what to do!" when Ash and co. confront it on taking their Pokémon. The English dub averts this, glossing over most, if not all, of Mewtwo's childish mannerisms from the Japanese version.
  • Akito in Fruits Basket. He's essentially the same at age 19 as he was when he was little - a spoiled brat with a god complex and a crippling fear of abandonment. This is because she was horribly abused from before birth by her mother, who forcibly raised her as a boy due to petty jealousy and drilled in her mind the idea that nobody loved her, nobody respected her, and everyone would abandon her, which caused Akito to snap when she was in her early teens and become the Big Bad.
    • Ren Sohma aka the aforementioned abusive mother of Akito. Not only is her ultimate reason to abuse her daughter ultimately very bratty (being jealous because Akira, her late husband and Akito's father, loved the idea of being a dad), but at some point she tries to kill Akito... over a box that belonged to the dead Akira, simply because she believes everything Akira owned was hers..
  • The "Vampire" Clair Leonelli from Heat Guy J is a Mad Bomber who speaks very childishly (referring to his dead father as "Papa", for example), is prone to violent temper tantrums, and is described by one character as liking to "play with" his enemies before he kills them. He does have a Freudian Excuse, though, and his childishness is designed to make him seem fragile and sympathetic as much as it's used to make him frightening.
  • Dilandau Albatou of The Vision of Escaflowne fame, the spiritual predecessor to Clair above, might be an even more obvious example, as when he's not fighting he spends much of his time throwing fits and having nervous breakdowns over things that range from understandable to entirely petty. While Clair above shaded into both Type B and Type C, Dilandau is squarely in B territory.
  • Gozaburo Seto of My Bride Is a Mermaid. While he's the boss of the Seto Clan and threatens Nagasumi, his wife Ren still sees him as a spoiled, immature brat who never left middle school and it shows. Sun even calls him out on it in the second episode ("I can't respect a father who won't even act like a man!").
  • Rosario + Vampire:
    • Gyokuro Shuzen is a mix of Types C and D. She's a powerful and beautiful vampire and the one-time matriarch of the Shuzen family... who's Evil Plan is nothing but her throwing a temper tantrum because she was insanely jealous of the fact that her husband Issa loved his mistress Akasha Bloodriver more than her. Everything Gyokuro does throughout the series (joining Fairy Tale, trying to Kill All Humans, etc.) is her way of spiting the long-dead Akasha.
    • Mizore and Kurumu's respective mothers, Tsurara and Ageha, are given this treatment in Capu2, having held a grudge against each other since high school over a boy they both had feelings for, and using their daughters' relationship with Tsukune as an excuse to continue their old feud.
  • Kishin Asura from Soul Eater has this side to him, although it only really shows during his final breakdown in the anime.

     Comic Books 
  • Deadpool.
  • Bizarro and Solomon Grundy from The DCU.
  • Amygdala, a minor Batman villain.
    • It's a bit of a stretch, but technically you can call most of Batman's Rogues Gallery this. Two-Face, Riddler, Calendar Man, Scarecrow (kinda), Firefly, Maxie Zeus... seeing as how psychology-driven Batman is, it makes sense that all of his villains would be so simply motivated. Most of them are just trying to prove something to Bats, making them the "Childish Motivations" breed.
      • Specifically, TRY to deny that Joker's motivations are... arbitrary. You will fail in this.
      • The Joker is arguably one of the more fitting examples in the Batman Rogues Gallery. For starters, when Batman is telling Joker to stay away from the Gordons after he apparently hurt Gordon's wife (it was actually his son, Gordon Jr. who did the deed), Joker commented that he didn't do anything to "the old bitch", and starts commenting to Batman that he misses the old Batman, and commented that he "doesn't want to go to bed yet" and that he "wants to play."
      • The original Blockbuster was the type A. variety.
    • Humpty Dumpty, a minor villain, is something of a subversion. He's enormously obese and strong, and clearly insane—but not in a way that makes him want to harm anyone. Rather, Humpty is obsessed with making things "better" by taking them apart and putting them back together again, but because he doesn't have any of the skills necessary to do this correctly, he ends up causing destruction and a few deaths instead. However, he doesn't do this maliciously: he sincerely can't tell that what he's doing is wrong, and helps Batgirl when she apprehends him by putting her dislocated arms back into her sockets, proving that he's not evil in any way. He's not in Arkham because he's a mass-murdering psychopath, he's in Arkham because he's actually crazy, and his doctors even view him as a model patient.
    • The Goddamn Batman could easily count as one, between his sadism and his petulance when people aren't impressed by his toys.
    • The Mad Hatter is probably the straightest example in all of comicbooks. His delusional obsession with a children's book and his kidnapping and murder tendencies come to mind.
  • Though a Serial Killer and not a Psycho for Hire, Johnny from Johnny the Homicidal Maniac fits the trope perfectly, mostly due to unfathomable mental instability.
    • And coming to Squee for a band-aide after cutting his hand on a "Skettie-Os" can probably clinches it.
  • Validus, from the Legion of Super-Heroes. A mindless powerhouse, easily controlled by his teammates in the Fatal Five. In the original continuity, he turned to actually be the child of Legion founders Saturn Girl and Lightning Lad (time travel was involved).
  • DC's Superboy-Prime: An alternate Clark Kent/Kal-El from a world where he was the only superhuman, which was destroyed. After helping to save the universe he spent years in a pocket dimension, (and didn't age or mature past his early teens), which drives him Ax-Crazy. A dose of The Punishment from the Guardians Of Oa gave him the power to traverse dimensions at will and destroy whole planets. To make things worse, he has the power level of the Silver Age Superman (only with a seriously warped morality), almost none of his weaknesses (only red solar energy will keep him in check), and a suit that ensures he is constantly charged with yellow sun energy.
    I'LL KILL YOU! I'll KILL YOU TO DEATH!!!
  • The 90's version of the Toyman certainly counts.
    "You're a bad mommy, I'm glad I killed your son!"
  • Billy Kincaid of Spawn. While the comic version is more Freddy Krueger-ish, the version portrayed in the HBO animated series definitely had the mind of a child. A child that liked to kill things. Mainly real children. With a paedophilia subtext.
  • The Flash villain (and later member of the Ineffectual Sympathetic Villains and Terrible Trio Injustice League) Big Sir is extremely large and powerful, but mentally deficient and easily exploited. He was eventually killed by a bio-engineered bomb designed to look like a small child while he was trying to hug it.
  • Sergeant Crumb, the largest man to serve in the British armed forces, in Adventures in the Rifle Brigade. Possessing strength that is rather unnatural even for a man his size (at one point he punched a man's head clean off his shoulders), and constantly sporting a mindless, toothy smile, he seems incapable of actual speech and only ever says "Ey-oop!" The conclusion reached by his superiors in his official dossier (which mentions several events where he's implied to have killed dozens of people) is: "Mummy, I'm frightened."
    • Similarly, Corporal Geezer only says "Yer aht of ordah!" and is one of the most prolific murderers in British history, being tried for over 413 murders before evidence was waived when he was assigned to the Rifle Brigade, which desperately needed a maniac like him to tie it together.
  • Bobby in the opening "Euthanized" story of Hack/Slash. A lot of people think Vlad is a rare good example because he talks funny, but he's cleverer than he likes people to think.
  • Larfleeze from Green Lantern has been living alone in a cave for billions of years with everything he's ever wanted being brought to him by his mindless constructs. This has given him the temperament of a spoiled three year old.
    • And, as seen in his Christmas Special, he believes in Santa Claus.
  • The Question villain Baby Gun. He looked like an giant toddler and used an air gun at close range to kill people.
    Baby Gun: Got'nee cake? Got'nee candy? Got'nee ice cream? Ahm'na kill yew!
  • Funland from The Sandman. A Serial Killer who preyed on children at an amusement park, wore Mickey Mouse ears and a Big Bad Wolf T-Shirt and liked "playing" with other kids.
    Not "fun", Funland.
    • To be clear, he's huge and pretty fat, and probably in his mid-thirties.
    • When Dream kills him causes him to fall into a magical slumber, he kindly lets him go having a dream that all the (dead) children come back and forgive him, and don't laugh at "the funny big giant," and they all play together forever and ever.
    • And then a panel of pink flowers is shown.
  • Alfie O'Meagan from Nth Man: The Ultimate Ninja is stuck at a mental age of ten. He's also a powerful Reality Warper who casually neutralized the world's nuclear arsenal and thinks nothing of turning into Godzilla or Galactus when he rampages against the armies sent to stop him.
  • Gideon Gordon Graves, the Big Bad of the Scott Pilgrim series, a Type C with some Type B qualities thrown in there just for fun. He's a wealthy and successful entertainment mogul, and the epitome of a Villain with Good Publicity. However, he seems to have the emotional intelligence of a seven year-old—he's petty, vindictive, possessive, can't handle rejection, and just wants people to adore him, even if he has to make them adore him against their will.
  • Dirty Ron from the Warren Ellis series Two Step. Just a simple, giant lad that likes to shag stuff - till it goes boom. He prefers cars to people, but when he wears his VR rig, everyone look to him like a purdy, purdy minicooper.
  • Gloo from Astro City is a Clone Degeneration Blob Monster. Its preferred method of combat is to subject its targets to distorted and deranged pranks and jokes, such as jamming two dozen people into a small car (like a Clown Car) or spraying acidic "seltzer" at victims.
  • Loki, in nearly all of his incarnations, is an ages-old Physical God with incredible intellect, cunning, magical might...and the emotional maturity of a spoiled toddler. His entire motivation for everything he has ever done can be summed up as "Waah, waah, Daddy likes my big brother Thor more than me!" and lashing out in response. In a conversation between his child incarnation and a copy of his former self, the child Loki actually comes across as the wiser and more mature of the two. Teen!Loki also has a bit more maturity due to his guilt over replacing child Loki. It's sort of inevitable that a self-proclaimed God of Mischief isn't a paragon of maturity.
  • Swamp Thing has napalm specialist Paulie Skinner, one of the D. D. I. goons who shot the Swamp Thing with a bioelectrical pattern-jamming device and then napalmed his body in an attempt to permanently kill the group's longtime enemy. The middle-aged Skinner is shown still living with his mom in a boyishly-decorated bedroom, with his mom tucking him into bed and bringing him hot cocoa. His happy dream in that scene shows him as a five-year old (with his balding, mustached, wrinkled head on the dream's toddler body) contentedly waving a rattle on his mother's lap — though the dream suddenly turns into a nightmare of his mother smothering him as the Swamp Thing, newly returned from space and seeking vengeance for being separated for months from his home and wife, suffocates Skinner under a massive pile of peach blossoms.
  • The Ten-Seconders: Damage is a super-strong super-durable rampaging beast, but he's actually very childlike. When he confronts The Scientist, he simply slaps Damage, puts him into time-out, then has him march into the sea on a fool's errand.

    Fan Fiction 
  • In the Day of the Barney Trilogy, Thorton Marshall is this. Adolf Hitler is also implied to be one, given that he was the only person who Barney corrupted that was not a child.
  • In the Pony POV Series, the Dark World version of Fluttercruel more than qualifies as a Type E. Despite being over a thousand years old by this point, she's still mentally a foal who, as Rarity puts it, no one ever explained the difference between a hug and a handgun to — she's a sociopath who gets her thrills torturing and killing things, and throws tantrums when Discord won't let her. This is the result as being raised by Discord, which resulted in her belief that she was showing love to her father by torturing ponies and that she was showing her mother love by torturing her. And this is all before she goes off the deep end.
  • Agent Diamond from Akatsuki Kitten: Phoenix Corporation Overhaul. It's not quite clear if she's type C, D, or E. She is stated to be quite intelligent despite less than normal comments, and has proven herself to be extremely powerful. She small, pretty, and has a relatively unassuming appearance and demeanor, which leads her instances of extreme violence, complete with creepy laughter to be even more disarming. And said laughter, as well as her background, show that her values aren't exactly the same as most peoples, particularly as she works directly for the author.
  • In the My Little Pony: Friendship Is Magic fanfic Cupcakes, Pinkie Pienote  is a Psychopathic MareFilly who loves inviting her friends to 'parties' which start with silly jokes and end with their hideous and torturous deaths.
  • Vanitas from The Shrouded Path is a mixture of Type B and C. Ultimately, he just wants to be loved by his surrogate parents. He's willing to go to extreme measures to obtain this.
  • Female version in Hivefled's Condesce, who along with her partner the Grand Highblood has murdered two and a half thousand teenagers for kicks and horrifically tortured her own son while cooing and cuddling him like he's a puppy.
  • Rosario Vampire: Brightest Darkness:
    • The original Jovian and Jacqueline Kikion who served Hokuto are a mix of Types C and D. They're both incredibly powerful and nearly unstoppable Hot Witches... and they're also completely Ax-Crazy Psycho Lesbians whose idea of fun involves such things as Cold-Blooded Torture, rape, and committing acts of wanton mass murder and city-wide destruction as a matter of course; they even explicitly describe their fights with Tsukune's group, during which they deliberately go above and beyond to kill as many innocent people and cause as much widespread destruction as possible, as "playing." To drive the point home, in Act III chapter 42, Jovian even cheers "Yay, I love killing!" in what the narration explicitly describes as a playful tone, and in Act IV chapter 25, when Gin saves Mrs. Aono's life after Jacqueline blows up Tsukune's house just to torment Tsukune, Jacqueline whines that Mrs. Aono should have died in the explosion and that Gin "didn't play fair."
    • Falla Cii, before she was killed and replaced with a Good Counterpart from an Alternate Timeline. Her reaction upon discovering that her parents had chosen her sister Luna to succeed them as rulers of the chronofly kingdom was to throw a childish fit and whine about how she deserves to rule more than Luna, before ultimately picking a fight with Luna and destroying said kingdom, along with the chronofly species except for herself and Luna, in a fit of rage.
      • Falla's Good Counterpart also falls into this for a good part of Act IV. As she was Tsukune's girlfriend in her original timeline, she simply cannot accept that this world's Tsukune is dating Moka, to the extent that she throws a temper tantrum and screams that it isn't fair and goes so far as to rig the entire girl's dorm with Death Traps in an attempt to kill Moka. The final trap she sets is quite infantile; a box-style rabbit trap containing a blood pouch and a sign reading "Free Blood," which Falla genuinely expected Moka to fall for.
    • Kahlua Shuzen retains this trait even after her Heel–Face Turn. Despite being the second oldest of the Shuzen sisters, she often acts like a young child, doing such things like whining and watching cartoons. It's also explicitly noted by other characters that every time Kahlua cries, she throws a temper tantrum; one such tantrum in Act IV chapter 2 almost leads to Yukari getting chopped up by her Blade Behind The Shoulder.
    • As in the original manga, Gyokuro Shuzen's entire Evil Plan is essentially just her throwing a temper tantrum over the fact that Issa had been more loving and attentive to Akasha than her.
  • In Sonic the Hedgehog fanfic Prison Island Break, beneath his mask of a cruel psychopath, Shadow is this. He has almost zero self-control and is almost pitiable in his subconscious desire for somebody who can keep him under control.
  • Sonic X: Dark Chaos features Beelzebub, the Lord of Flies. A death metal druggie and Mad Scientist, he's also a sadistic pedophile who gets off on Cold-Blooded Torture. After capturing them, he ends up raping Chris and almost-raping Cosmo simply because he wanted to feel how "tight" they were.
    • Tsali is basically this trope personified, often going straight into Ax-Crazy with his playful attitude towards violence and bloodshed. It's justified later on with the reveal that he was turned into a robot by Cosmo's race when he was only ten, which prevented him from ageing physically or mentally - and the entire Metarex War was basically a genocidal temper-tantrum over it. Also lightly deconstructed, as his lack of self-control nearly ruins Maledict's plans several times.
  • The Bound Destinies Trilogy:
    • Veress, the Big Bad of Blood and Spirit. The reason for her Face–Heel Turn is incredibly petty and childish: she was passed over as leader of the Sheikah in favor of Sheik. In a nutshell, for all of her charisma and power, in the end Veress is nothing but an immature brat throwing a temper tantrum because she didn't get what she wanted.
    • Veress' descendant Veran of Wisdom and Courage displays a lot of childlike evil. She has an ego that's bigger than Hyrule and Termina combined, treats killing innocent people and destroying villages as a game, constantly feels the need to gloat to Link and Zelda about how much better she thinks she is than them, and more or less acts like a child with a new toy when she gets the Triforce.
  • "Sweetpea" in Except It Abide In The Vine is a zig-zagged Type A, portrayed sympathetically. He's an alternate version of the Winter Soldier from a dystopian HYDRA-ruled reality, and he's dealing with the aftereffects of HYDRA brain surgery as well as the usual brainwashing, so he has issues even by Winter Soldier standards. At first, Sweetpea appears to be vicious, feral Dumb Muscle. Then he gets a chance to calm down, and out of combat he turns out to be a strangely cute, overly affectionate weirdo with some communication problems. Then the team's dimension-hopping lands them in a warzone and Sweetpea bites a Nazi mook's throat out. His overall characterization averages out at "a bit unstable but weirdly adorable outside of combat, pants-wettingly brutal in a fight," a bit like a giant muscular cyborg River Tam.

    Film - Animated 
  • Scar from The Lion King. Best exemplified when he says "I'm king, I can do whatever I want!"
  • Kadaj and his group from Final Fantasy VII: Advent Children, a group of superpowered teens created from Sephiroth's refusing-to-be-dead essence. Kadaj, a mix of B and C, can go from vicious and sadistic to heartbreakingly childlike and back again in the span of around fifteen minutes. His older 'brother' Loz also qualifies as type A, being less psychotic, but more childlike. Probably Yazoo as well, as type C. He doesn't get much screentime, but just watch him laughing in childish excitement in the extended version as he steers his motorcycle off an exploding bridge to attack an airborne helicopter.
  • Syndrome in The Incredibles balances a genius-level talent for inventing technology with an incredibly childish personality; he's immature, excitable, petulant, irresponsible, prone to mood swings, obsessed with gadgets and 'toys', and spiteful. His motivation also stems from an admittedly wounding and hurtful, but still relatively minor slight, he suffered when he was a child, which he refuses to move on from.
  • Prince Charming in Shrek the Third. A huge Momma's Boy who relied on said Momma for everything before her death in the previous movie, his entire Evil Plan is motivated by a mixture of revenge and pleasing her. Once he's taken over the throne, his first act is to make a stage adaption of himself and about how cool he is. Case in point, his Famous Last Words: "Mommy?"
  • The Bowler Hat Guy from Meet the Robinsons.
  • Prince John from Robin Hood. A petulant, temperamental, selfish, impulsive crybaby who sucks his thumb and cries for his mommy. The real Prince John (later King John) is often depicted this way in other works, but whether he truly was is impossible to say.
  • Gaston's role in Beauty and the Beast consists of him throwing a very violent temper tantrum when he doesn't get what he wants.
  • Smek in Home is the leader of an entire planet, who throws himself on the ground and cries out loud like a toddler when he doesn't get his way.

    Film - Live Action 
  • Leatherface from The Texas Chainsaw Massacre is a mentally-retarded tool of his family, who uses him to gather meat for their restaurant.
  • Jason Voorhees, of the Friday the 13th films, is a dimwitted undead creature who kills because he thinks his mother's ghost is commanding him to do it.
  • Jacob Goodnight (as played by pro wrestler Glen "Kane" Jacobs) in See No Evil. Like Jason and Leatherface, his madness resulted from childhood trauma.
  • Michael Myers is actually an aversion. In the original Halloween (1978) he just kills his sister without any real reason. Dr. Loomis describes him as being "pure evil". It wasn't until the remake that he became this. This was a major criticism since it took away from the looming mystique of the original character.
  • Loki in Dogma. Since Angels apparently don't have a conscience and he used to be the Angel of Death, before resigning when he got pissed, there may be a reason to this.
  • Loki (again) in the Marvel films. In Thor, his motive is killing all the frost giants in order to gain his father's approval. In The Avengers, he wants to rule Earth in part because he feels he is owed a throne (lampshaded by Odin in the next film). His whole evil shtick reads like a cosmic temper tantrum because he's Daddy's unfavorite and because he's tired of living in Thor's shadow. Plus being the God of Mischief and all, he has a thing for pranks and tricks. He's like Deadpool times God.
  • Norman Bates from Psycho has a gangly childishness, due to his mother's isolating and dominating him. It becomes more obvious when Lila Crane snoops through the Bates home and comes across Norman's room.
  • The movie Mad Max: Beyond Thunderdome, has the title character facing off against "Blaster" in the eponymous Thunderdome. ("Blaster" is the masked, hulking, none-too-bright bodyguard of Master, one of Bartertown's leaders.) Max outthinks Blaster, knocks off his mask, and is all set to kill him when he discovers that Blaster has Down Syndrome and is essentially a child in a giant's body. Max relents, but the people who hired him to kill Blaster aren't feeling quite so charitable...
    • Also in Mad Max: Fury Road, Nux is curiously innocent and non-malicious, even while he's killing loads of people. And Rictus, who is the big Dumb Muscle variety. Showing little independent thought, he seems only to want to please his father.
  • Most of the villains in the Burton / Schumacher Batman series.
    • It's almost obligatory to depict The Joker this way, but the 1989 film takes it a step further by showing him as the apparently sane (but still very, very evil) Jack Napier prior to his transformation. In between the vicious murders he committed as Napier and then continues to commit as the clown he becomes, the Joker "punches out" two television sets with a gag boxing glove, blows into a birthday-party noisemaker (possibly the film's single funniest scene), obsessively cuts up photographs to make collages of them, hosts a parade with giant cartoon-character balloons, makes funny sound effects with his mouth, and sends the woman he's stalking a note written in crayon.
    • In Batman Returns, the Penguin spends a good deal of screentime wearing only a onesie-like garment stained with his own spittle and slobber. Furthermore, he rides around in a giant toy rubber-duck vehicle and amuses himself with an umbrella (among his collection of genuinely deadly ones) hung with little plastic animals reminiscent of a mobile found in a baby's crib. ("Shit! Picked the cute one!") Actually, the Penguin is more of a Type C - a quite sane and intelligent (though, again, extremely evil) man who simply has not been able to grow up because of his Daddy Issues.
    • While vandalizing - and ultimately blowing up - a department store owned by the man who attempted to murder her, Catwoman takes some time out from her mischief to girlishly "skip rope" with her trademark bullwhip.
    • Near the climax of Batman Forever, the Riddler and Two-Face play a game of Battleship that uses real torpedoes - and the Batboat (piloted by Robin) is their target.
  • The DVD commentary for Thir13en Ghosts provides backstory for the Black Zodiac. This trope is represented by The Dire Mother and The Great Child, the Mother being a little person in a travelling circus and the Child being the result of rape by the circus' Tall Man. He was extremely spoiled by his mother and appeared as a fat, hulking brute of a man wearing diapers and a bib and carrying the axe with which he had killed his mother's murderers.
  • Kim Jong-un as portrayed in The Interview. He is so volatile and insecure that he flies off the handle and tries to nuke the whole world just to demonstrate his worth as a leader. After Dave manipulates him into crying on camera, he shoots him in anger. Thankfully Dave was wearing a bulletproof vest.
  • Tokka and Rahzar from Teenage Mutant Ninja Turtles II: The Secret of the Ooze. As David Warner's character puts it:
    They're not stupid. They're infants. (Beat) Okay, they're stupid infants.
  • The Merrye siblings in Spider Baby or, the Maddest Story Ever Told, who have a condition that causes them to revert intellectually until they have childlike minds in full-grown bodies. This enables them to do things like kill deliverymen as part of their games, and demonstrates how excellent it is that humans can be taught morality before they're big enough to do real damage.
  • Repo! The Genetic Opera's Luigi Largo is a rather brutal murderer, and most of the time seems like a functional adult, but a stern look from his father or a sharp word from Mag can turn him into a contrite toddler. He also throws temper tantrums that would be hilarious if he didn't have a knife in his hand while he had them. At the end of the film, after Rotti's death, he breaks down sobbing in the middle of menacing a crowd of people.
  • Zigesfeld in If Looks Could Kill displays multiple signs of mental retardation, including a childlike dependence on the film's female villain. When she strokes his mechanical hand in one scene to calm him down, he grins like a little boy. Of course, all of this gives his one and only line in the movie ("Shut up, you whiny bitch!", delivered to the understandably panicked and babbling French teacher after having hijacked the bus that she and her students were on) a totally different dimension than it might otherwise have had.
  • The towering 'trolley boy' Michael "Lurch" Armstrong in Hot Fuzz. According to Danny, he's a product of incest and has the mind of a child. When the members of the NWA are booked at the end of the movie, he's bawling like an infant
  • The 1963 film Cleopatra portrayed Octavian (the future Augustus Caesar) as one of these. The historical community was Not Amused.
  • Lila, Eddie's insane new wife in the 2007 remake of The Heartbreak Kid. This is best captured in her reaction when she gets a horrific sunburn and Eddie points out that she should've worn sunscreen: "Who's side are you on, mine or the ozone's? Choose one!"
  • The main villain of The House by the Cemetery is hinted to be one, as he is constantly crying like a little child. The film even closes by a quote by Henry James Lucio Fulci that says "No one will ever know whether the children are monsters or the monsters are children".
  • Grindhouse:
    • In Don't!, one of the joke movie trailers, Nick Frost has a cameo as a cannibalistic man-baby locked in the basement of the house. Part of the central joke of the trailer is that everything happens too quickly to get a sense of what kind of horror movie it is, so it's hard to say much more about his character.
    • Stuntman Mike in Death Proof, one of the actual films featured in Grindhouse. He puts on a suave act, but at his core he's a vindictive juvenile who gets off on doing cruel things to people. His demeanor in the last act, when he comes across some women who fight back, is that of a kid whose prank has backfired on him.
  • Olaf in The Sinful Dwarf is a particularly frightening and extreme example. He plays around with eerie wind-up toys and uses them to lure girls in to be used as sex slaves. Just watching Olaf can be nauseating.
  • The eponymous character of The Mask. By the Doctor's analysis, the mask actually makes to surface all the "inner child" from that person, so it fits for all characters ever wearing it.
  • In Suicide Kings, one of the No Name Given kidnappers holds a gun to his partner's head, cocks the hammer, and begins to pull the trigger...because his partner changed the channel while he was watching a cartoon and wouldn't change it back. After he leaves, the partner checks the cylinder of his gun and finds that it was fully loaded.
  • Near the end of The Last King of Scotland Nicholas is captured by Idi Amin's men trying to flee the country, tortured and confronted by the dictator, leading to this little exchange:
    Idi Amin: I am the father of this nation, Nicholas. And you have most... grossly... offended your father.
    Nicholas: (battered and bloody) You are a child. That's what makes you so fucking scary.
  • The Ghost of Christmas Present from Scrooged is a female example.
  • Team America: World Police's depiction of Kim Jong-Il.
  • Suzanne Stone of To Die For is an evil woman who seduces a (very dim) teenager to get him to kill her husband, and her intellect level is just barely above his, or above a child.
  • Shinzon of Remus from Star Trek: Nemesis. He initially justifies his actions by a desire to free his people, and then by a desire to unify Romulus and Remus, and then by a desire to remove the threat posed by the Federation...but by the end of the movie, it becomes pretty clear that all that he really cares about is proving his superiority to his "father" Captain Picard.
  • The various Harry Potter film adaptations portrayal of Bellatrix Lestrange depicts her as having shades of this. For one thing, shortly after murdering Sirius Black, as well as her re-encounter with Harry at the burrow, she taunts Harry about her direct involvement in Sirius Black's death by singing "I killed Sirius Black!" repeatedly in a similar manner to a playground taunt by preschoolers.
  • In A Fairly Odd Movie: Grow Up, Timmy Turner!, the Big Bad, Hugh J. Magnate, ultimately turns out to be one once he gains access to Cosmo, Wanda, and Poof's magic. This is foreshadowed by the fact his evil lair is designed more like a playland. He says that this came from the fact his father never let him have a real childhood.
  • Sarah from Hocus Pocus.
  • Baby Firefly from the House of 1000 Corpses films. She cuts the heads off of dolls and nails them to the wall, has a childish high pitched voice and giggle, and recited the Rabbit Hutch rhyme while murdering a woman that she put in a rabbit suit.
  • William "Wild Bill" Wharton, from The Green Mile, displays shades of type C of this trope, at least in the film. Despite being on death row, his antics seem more childish and goofy than anything else, sometimes being played for laughs, until it's revealed he raped and murdered two little girls while working as a farmhand, a crime for which John Coffey takes the blame.
    • Coffey himself is viewed this way in-universe, at least by the attorney who prosecuted him. When the main character stops by the attorney's house to protest Coffey's innocence, the attorney tells him about a dog he once owned who would bite people and then act sorry afterward, implying that John Coffey is much the same way.
    • Percy Wetmore himself is this. He is basically an out-of-sorts brat in the body of a death row guard, and any time he is told off for his idiotic behavior, he whines to his uncle, the governor. His horrible treatment of Delacroix- smashing his fingers, letting him fry horribly in a chair by not wetting his sponge- comes across as bullying rather than discipline.
  • Murder Party: At least three of the murderous artists (Bill, Lexi and Macon) are quite immature. Especially Macon who always wants to feel that he has a powerful presence and acts over-the-top (even when its impractical to do so) to get attention. The above mentioned belief about John Coffey? Well Macon embodies it perfectly, screaming like a maniac while attempting to murder Chris andthen acting sorry afterward.
  • Butterfinger, the Dumb Muscle of the group of rogue CIA agents in Hudson Hawk. At one point, when the other agents are complaining about how long Hawk is taking with his Love Interest, Butterfinger asks, "You want me to rape 'em?" There's a long, uncomfortable silence, and then one of the other agents hands Butterfinger a book to distract him. It's Dr. Seuss' Green Eggs and Ham, which Butterfinger seems to struggle with.
  • Charlie Chaplin's The Great Dictator's depiction of Hitler is of this trope, as evidenced by how he interacted with his "globe."
  • Agent Lynch from The A-Team acts like a 16-year-old with daddy's credit card and car keys. He leers at his assistant, constantly brags about how much cooler his job is than his opposite number's, and displays childlike glee at all the cool toys he gets and stuff he gets to do.
  • Chronicle: What Andrew Detmer becomes by the end.
  • The movie Game Over has one, in the form of a supercomputer named Drexel, which threatens to destroy the world unless someone plays video games with it. To add to the effect, Drexel is voiced by a child actor.
  • Pee-wee Herman edges close to this trope in some parts of Pee-wee's Big Adventure, especially when he is shown becoming increasingly obsessed over the theft of his bicycle.
    • His Nemesis, Francis Buxton, is even worse. Even Pee-wee thinks he's ridiculous. Also, Pee-wee owns his own home while Francis still lives with his wealthy father.
  • Skank in the film version of The Crow. He's a rapist, a murderer, and a car thief. He also frequently acts like a brain-dead hillbilly and is treated as a Butt Monkey mascot for the rest of the gang, and he cries like a little boy whenever he's in danger. He eventually becomes so cowardly and pathetic that he essentially turns into an Ineffectual Sympathetic Villain, and the film has to flash back briefly to Skank's rape of Eric Draven's girlfriend in order to justify Eric's killing of him.
  • In Naked Gun 33 1/3: The Final Insult we have Tanya Peters, the moll in a band of mercenary terrorists. She actively participates in the gang's crimes, and seems to know exactly what she's doing (and also that the gang's ultimate goal is to blow up a building full of hundreds of innocent people)...and then there are other times when she seems completely oblivious to the fact that she's surrounded by ruthless criminals - or that she is one herself - and comes across as more of a Spoiled Sweet Brainless Beauty. Eventually, she has a Heel Realization and rats out her accomplices. This was all Played for Laughs.
  • Amon Goeth in Schindler's List. He has tantrums like a child, does things on a whim, and likes to break his toys. Unfortunately, in this case, his toys are human beings being starved and worked to death, who he kills on the merest whim (e.g., he wants to kill someone). Accent on the "merest" part.
    Goeth's Mistress: "Amon, you're such a damn fucking child!"
  • Johnny Truelove of Alpha Dog is an impulsive, shortsighted, criminally dumb wannabe gangster trying to project a "tough guy" image. He kidnaps Zach on a whim, threatens people wherever he goes, and doesn't realize how many witnesses he creates because of his own poor planning. He doesn't even keep tabs on the murder he orders while going out with his girlfriend and having fun, and rejects the option his father offers to release Zach and spend minimal jail time even though he has no other plan himself. He remains elusive for so long only because of blind luck.
  • Blue Jones from Sucker Punch outright tells the protagonist that he feels like a little boy sitting on the edge of a sandbox, watching everyone else play with his toys, just before he tries to rape her...
  • Gary from The Gamers films is not a villain, but he falls into this territory during his Sanity Slippage at GenCon in Hands of Fate. Most geeks can sympathize with the pain of becoming emotionally invested in something Too Good to Last. But is repeatedly physically assaulting the costumed mascot of the series that you blame for your favorite show's cancellation really the behavior of a sane adult? (It's also worth noting that Ninja Dragon Riders, the late, lamented series in question, appears to have been intended for the Shōnen demographic. So for additional Psychopathic Manchild points, Gary's being driven to violence by his emotional overinvestment in a program intended for twelve year olds.)
  • Silva from Skyfall has an almost gleeful childlike attitude when it comes to what he does. But it's best exemplified at the end when he realizes M is slowly bleeding to death, he devolves into a whimpering, scared little boy and proceeds to lovingly embrace her while begging her forgiveness.
  • In X2: X-Men United, thanks to the brain surgery, Jason Stryker's both very easily manipulated and childishly devoted to his abusive father - to the point that when Magneto catches up with him, all he needs to do in order to change Jason's mind is have Mystique transform into Stryker and give him a new set of orders. For good measure, within his illusions, he usually depicts himself as a child.
  • The Emperor in Return of the Jedi acts very giddy when he taunts Luke, trying to get Luke angry. And his torture of Luke is more childish sadism than actual anger.
    • The Force Awakens: The film's Heavy, Kylo Ren, appears quite intimidating at first, but it doesn't take long for him to show his true colors. Despite being a dangerous Dark Side Force-user, Ren is still very immature. He has an obsession with Darth Vader justified, since Anakin is his grandfather, suffers from serious Daddy Issues and throws literal temper tantrums whenever things don't go his way, trashing whatever machinery he can reach with his lightsaber. He might be in his late twenties, but it's fair to conclude that he never really grew up. That said, Ren's emotional inhibitions are somewhat justified, as he was targeted by Snoke, manipulated and lured away from his family in childhood. But again, he is extremely dangerous, even to the point of murdering Han Solo, his own father, just as he is on the verge of tears and Han is trying to comfort him, no less! Overall, he comes across as a genuinely dangerous yet somewhat pathetic wannabe dark lord when compared to the likes of Vader and Palpatine.
  • Middle-Eye in Apocalypto. For all his sadism and warrior skills, he can revert to childlike behavior. He screams at getting bitten by a woman defending herself, greedily takes a keepsake from a fallen comrade ("He would have wanted ME to have it!"), throws what's essentially a temper tantrum when forbidden from killing the hero, and becomes meek and tongue-tied after trying leader Zero Wolf's patience. Somehow it doesn't make him any less scary.
  • Lucille Sharpe from Crimson Peak is a dangerous and intelligent antagonist but in some situations, especially in the climax, she behaves more like a child in a full grown woman's body. She's prone to fits of jealousy, impatient, likes to sing her childhood lullaby frequently and by the end, she kills her brother and lover Thomas when she finds out he's genuinely in love with Edith. When she kills him, her crying isn't that dissimilar to that of a upset child.
  • Wade Wilson in Deadpool is a rare protagonist example, due to his combination of immature goofiness, Comedic Sociopathy, and high body count. Colossus even describes him as a "heavily armed child."
  • Lex Luthor in Batman v Superman: Dawn of Justice is presented as extremely childish, yet powerful evil genius.

    Literature 
  • Sidney Carroll's short story "None Before Me" features a fascinating, horrifying art connoisseur named Gresham who hoards the most priceless, exquisite works of art in the world, and toys with them like a child. He buys an enormous dollhouse described as "the best in the world" and places it in the center of his collection, obsessing over it every waking moment of the day. As the house absorbs his attention, he begins rearranging the furniture inside and talking to the dolls as if they are real people, and eventually he decides that he is the sole God over the people "living" inside the house. One day, he discovers a figurine of a religious idol inside the house; the "blasphemy" enrages him and he smashes the priceless house with the back of his hand, destroying it– then promptly dies himself.
  • In A Brother's Price, Keifer Porter. Emotionally abused all his wives, cruelly tortured and raped one of the younger ones, and used his Brainless Beauty to not be punished for it by the elder sisters. Everyone agrees that he was simple-minded, and childish, though not without some cunning. Turns out there was someone more intelligent than him behind his poisoning his father-in-law.
  • In one of the creepiest moments in the Agatha Christie canon, when the murderer in "Three Blind Mice" finally reveals themselves to their intended last victim, their voice suddenly devolves to that of a child.
    "I said that I'd kill you all when I grew up and I meant it! I've thought of it ever since! I'm grown up now; grownups can do what they like!"
  • Merricat in We Have Always Lived in the Castle. She started out as a psychopathic child and is still very childlike though over 20.
  • Mr. Teatime of Terry Pratchett's Hogfather is one of the creepier examples.
  • Another Pratchett example: First Mate Cox in Nation is at one point given a description suggesting this, when his gleeful expression at shooting down a parrot was compared to a little boy proud of wetting himself. On the other hand, at no other point is he shown as anything but fully, rationally aware of what he is.
    "First Mate Cox had a choice, every day, and had chosen to be First Mate Cox."
  • Doopy and Goshy the clown brothers in The Pilo Family Circus are insane like all the other members of the clown division, but manifest their particular lunacy in remarkably childlike ways which seem quite harmless at first: Doopy has the mental age of about six years old and has a habit of whining like an impatient child, while Goshy communicates only in whistles and beeps and is in love with a potted plant. However, Goshy's apparent incompetence is offset by his appetite for wanton destruction and uncanny bursts of sadistic intelligence, and Doopy will fly into a homicidal rage if his brother is even mildly threatened.
    • JJ, the protagonist's vile alter-ego, will gleefully commit murder, vandalism, assault, and any number of crimes for his own childish amusement. However, if anyone responds violently or threateningly, he'll react by bursting into tears and running off.
  • The Howlers, an ancient race of genocidal warriors in Animorphs. Jake was essentially expecting them to have the mind of a super-predator, but upon morphing into one, he discovers to his shock that they are actually possessed of a childlike simplicity and engage in genocide because they think that it's just a fun game and don't understand that they're hurting people. Eventually, the Animorphs were able to exploit this by revealing to the howlers that their victims are more than just mindless toys which exist for their amusement, thus "ruining" them.
  • The Somnambulist by Johnathan Barnes features a pair of these, called The Prefects.
  • The (presumed) Big Bad of The Meq is the Fleur-Du-Mal, who, like the rest of the eponymous race of immortals, is Really 700 Years Old, but he's also a Psycho for Hire with a bone to pick with the rest of his race. He likes to cut throats, kidnap little girls and turn them into prostitutes, dabble in the occult, manipulate normal people, or Giza as they're called, with his appearance as a twelve-year-old boy, and sadistically torment his own kind. Yeah, he's a Jerk Ass.
    • Soon, Ray's sister, Zuriaa was dangerously unstable and became Fleur-de-mal's twin. What a plot twist.
  • In the Redwall book Martin The Warrior, the heroes come across a tribe of Chaotic Neutral wild squirrels who live for pleasure and think it would be a really fun game to chase said heroes up a cliff and throw them off! They do end up working for the good guys later on, as they're convinced this would be an even better game.
    • Also, the horribly spoilt Prince Bladd from Triss (though his age is unclear, so he may in fact be fairly young). He likes playink mitt fire.
  • In Tad Williams' Otherland, the Other is the quasi-sentient operating system of the eponymous network. One of its many bizarre attributes is that, despite being at least twenty years old, it seems to have the personality of an autistic child, and at several points in its "development", the Grail Brotherhood attempted to have it communicate with real children, in order to allow it to develop the capability to interact with people. The Driving Question of why an apparently home-grown AI behaves this way is only resolved when it's realized that the Other is not actually an AI; it's a real human child, stolen at birth and implanted as the "brain" of the network.
  • Ronald Niedermann from the Millennium Trilogy. Freakishly strong, near-invincible due to congenital analgesia, and extremely intelligent. He is also irrationally devoted to his unloving father, has probably never physically achieved puberty, and is plagued by bizarre and terrifying hallucinations. Knowledge of which (or not) can come in fairly handy.
  • In Codex Alera, this seems to be the eventual demeanor of the Vord queen as she slowly becomes more and more human in her emotions.
  • Nightblood from Warbreaker is a lot like this, acting much like an optimistic child eager to please its owner — by killing things.
    Nightblood: I did very well today. I killed them all. Aren't you proud of me?
  • From Harry Potter: Dolores Umbridge, Bellatrix Lestrange, and arguably, Voldemort himself.
  • In Death: A number of the murderers can be considered this. That doesn't make them any less dangerous, though.
  • The Phantom of the Opera: Type B and C. In the original book the Persian and Erik himself lampshade Erik's attitude as childish, and despite his multiple talents, he is not interested in sex but to have a beautiful wife and a life like any other guy. It's only when he actually triumphs that he realizes how impractical those dreams are. Also the Persian treats him as a spoiled child when he interrogates Erik about Raoul and Christine destinies.
  • Mirror, Mirror: The Borgia siblings are both C and E. Though they're less Ax-Crazy than unable to understand basic concepts like "breaking promises, ordering assassinations and sleeping with family are bad, bad things".
  • A Song of Ice and Fire:
    • Lysa Arryn throws tantrums like a spoiled child when things don't go her way and ignores her responsibilities as Lady of the Eyrie in hopes that they would go away. And when her new husband Littlefinger forcefully kisses her niece Sansa, she tried to murder the latter because she believed they tried to steal what belongs to her.
    • Cersei Lannister covers her inner woman-child with a huge layer of The Vamp (and all the Manipulative Bitchiness that requires), in addition with twisted aspects of Mama Bear in adulthood. But, her primary motivation for much of what she does is what it's been since she was very young... a humongous tantrum that she can't get the cool toys like the boys do (or, more specifically, like Jaime does). And, Daddy won't look at me like he does him! (So, I'll be better than Daddy!) It's not very pleasant when it combines with a streak vicious enough to advocate torture, murder and, occasionally, outright acting like her brother's (and cousin's) Lady Macbeth when she isn't being her children's My Beloved Smother, so any sympathy you might have for her points about the inherant unfairness in the Stay in the Kitchen attitude of most of Westeros gallops out the window thanks to her general toxicity.
    • It's still up in the air about the inner workings of Petyr "Littlefinger" Baelish. Whilst the execution of his plans are certainly mature, he is solely motivated by his by his childhood affection for Catelyn Stark. His plan so far can easily be viewed as a massive temper tantrum simply because he couldn't have her for himself, leaving almost the entirety of Westeros devastated by war and with winter just around the corner too...
    • Ramsay Bolton is still the little boy who pulls the wings off flies, roasts living grasshoppers, drowns kittens and beats nerds for lunch money whenever he feels like it inside. Just all grown up enough to add raping and flaying people to the list of things he enjoys doing.
    • Gregor Clegane is a downplayed one of these as he's not the giggling, vocalising kind and comes across as quite thick. However, he's not good at sharing his toys (he's killed most of his family and antagonised his brother into staying well away from home) and has an epic set of triggers you don't want to trip. He also likes to surround himself with similarly-minded, violently sadistic bullies.
  • Vlad Tepes in Count and Countess.
  • Given Palpatine's views in Darth Plagueis, its strongly implied that Palpatine grew up to become a high functioning version of a Psychopathic Manchild.
  • The Colorman in Christopher Moore's Sacre Bleu who always shrugs off his murders with "Sorry. Accident. Couldn't be helped." and his molesting the female help with "Penis".
  • G. K. Chesterton's Manalive features Innocent Smith, an apparently mad Blithe Spirit who gleefully takes charge of a small community and changes everyone's lives for the better... before pointing a gun at someone and being arrested as a serial killer. It's gradually revealed that he has never, in fact, killed anyone.
  • The Tome of Bill has two examples.
    • First is Jeff. He acts incredibly childish and has exaggerated opinion of himself. He throws a fit whenever he doesn't get his way and is generally an all-around douchebag.
    • Second is Gansetseng. She's actually over three hundred years old, but she was turned when she was just twelve and hasn't physically aged since, and has barely aged emotionally thanks to her "father" (actually her some odd great-grandfather) treating her like a child for all her life.
  • According to The Disaster Artist, Tommy Wiseau is this as he acts very childish throughout the book, even when he's trying to manipulate someone.
  • John Dies at the End has an interesting example in that the Psychopathic Manchild is Korrok, a gigantic amorphous Eldritch Abomination with the mental maturity of a 13 year-old who just discovered his first batch of cuss words. People under his control tend to do things like blurt out offensive comments and do strange and depraved acts like stripping naked in the middle of the street and packing snow onto their crotch or pissing on the hood of the protagonist's car, and his idea of tormenting the protagonist is to turn on his car radio and replace all the song lyrics with racist diatribes. When Dave and John finally meet him, Dave notices that his voice sounds like a toddler's.
  • Lennie in Of Mice and Men could be considered this, aside from the fact that he is not psychopathic. Unless you count the fact that he outright murdered Curley's wife because she was screaming. And she was only screaming because he was hurting her, and wouldn't let go of her.
  • Reach, the King of the Cranes, from the Skyscraper Throne series is a particularly extreme example. On the surface a nigh-unkillable, several hundred year old god, underneath he's a Fetus Terrible, struggling to be born.
  • The Queen of Hearts, from Alice's Adventures in Wonderland, is a Psychopathic Womanchild — though she presumably rules over Wonderland, she's essentially an overgrown spoiled brat who, upon being crossed or annoyed by someone, starts screaming her famous "Off with his/her/their head(s)!" The narrator points out that this is quite literally the Queen's only way of dealing with any problem, regardless of its size. Many adaptations of the book, including Disney's animated version, keep this characterization, making the Queen of Hearts into a temper-tantrum prone villain who switches from sweetness to screaming without any warning.

    Live-Action TV 
  • Todd from Breaking Bad turns out to be a rather understated case of this trope. He appears to be at least in his mid to late 20s but acts a lot more like an awkward 14 year old. Most of the time he tries to be polite and considerate to other people but it often seems like an imitation rather than anything real. He also ends up carrying out the most shocking atrocities in the series: Casually shooting a child, torturing Jesse to learn what he told the DEA and to cook meth for him, murdering Andrea to keep Jesse cooking for them, and intimidating Skyler by threatening to kill her infant Holly. Murder seem to mean nothing to him whatsoever.
  • Buffy the Vampire Slayer:
    • Glory is a mix of Types C and D. She's a pretty blonde girl with massive Super Strength, Super Speed, and Nigh-Invulnerability... and a Spoiled Brat who's default response to not getting her way is "throw destructive temper tantrum and murder anyone in my way." At the very end of her debut episode, after breaking the heel on one of her shoes, she starts stomping in a childish rage, which causes the entire building she's in at the time to collapse on top of her.
    • Warren Mears. The reason he founded the Trio in the first place was out of boredom and to get respect. In "Seeing Red," the very first thing he does upon gaining the Orbs of Nezzla'Khan is beat up a jock who bullied him in high school, and after thwarting his latest plan, Buffy flat-out tells him to his face that he's nothing but a "sad little boy" who needs to grow up.
    • Drusilla loves flowers and puppies and squeals with childish delight at seeing people killed in horrible ways.
  • Daniel Tosh's television and Stand-Up Comedy personas are very much Type C.
  • Melvin Potter in Daredevil. There are hints before and during his fight with Daredevil that something's not quite right about him, and the sheer brutality of the violence he inflicts on DD combined with his childishness makes him look like this. Subverted: it turns out he's not psychopathic at all; he's developmentally disabled, only working for Fisk because Fisk has a hostage that he cares about, and he's lashing out because he's terrified. Once DD manages to calm him down, he's quite reasonable and eagerly offers to help if DD will free his friend.
  • Battlestar Galactica: John Cavil is eventually revealed as an angsty teen stuck in an old man's body with a load of Mommy Issues to boot since said old man's body was based on his "mother" Ellen Tigh's father (it's probably a good thing she didn't know that when he forced her to have sex with him). He also killed his brother(s) Daniel out of jealousy.
  • Blackadder II gives this treatment to Queen Elizabeth I, of all people.
  • Al Capone in Boardwalk Empire shoots Jimmy Darmody's pillow while he was sleeping as a joke. He also gives his boss Johnny Torrio an exploding joke cigarette in the middle of a meeting. Johnny is not amused.
  • Community:
    • Chang enjoys wielding the power of being a teacher like a bratty ten year-old would, and is prone throwing tantrums at the tiniest (if any) provocation.
    • Pierce veers into this, particularly in S2, with the lengths he is willing to go to to make the other students' lives hell just to get attention, and has had a number of psychotic breakdowns. He's seen (and acts) in-universe like a rebellious teenage son to Jeff and Britta, despite being older than either of them.
  • Many of the serial killers in Criminal Minds are emotionally stunted, but special mention goes to the killer in the two part "To Hell ... And Back", an emotionally and mentally retarded middle-aged man whose quadriplegic brother directed him to pick up transients so he could use them in the smarter brothers' experiments.
    • There's also the (wo)manchild in "Uncanny Valley", who paralyzes women and plays house with them, but she's very sympathetic: her psychiatrist dad repeatedly gave her shock treatments to make her forget his sexual abuse and kept her dolls as trophies, along with all his other trophies. Give her some real — er, actual dolls and she's perfectly safe.
    • Joe, the mentally retarded Monster Clown from "Damaged". Despite being in at least his thirties, he's extremely childlike, when he's finally caught he weeps like a child and screams for his daddy. But don't feel too sorry for him he stalked a little girl through a carnival, then broke into her home and murdered her parents with an axe. For twenty years he was That One Case to Rossi.
    • There is also Cy in "Proof", who, despite being born with brain damage, is unsympathetic. The reason for this is that, unlike the examples above, there is no indication that Cy's mental handicap is the cause of his behaviour; for all his childishness, he is not incapable of knowing right from wrong, and says that he learned when he was a child that kicking his dog was fun, and he kills for the same reason. He also has the same misogyny as many other killers, takes trophies of his victims, and plans to avenge perceived wrongs by making his brother watch the tape of Cy mutilating his daughter, and by the end of the episode it's clear that, even without his handicap, he would still be a Serial Killer (and a particularly sadistic one at that, he rapes and takes away his victims' senses with sulphuric acid to kill them).
    • The most recent one, a guy who transformed his victims into actual People Puppets, at least has the excuse that a serious brain injury caused his personality to revert back to his childhood when his puppeteer father was murdered by a robber; he was young enough that he thought the puppets were real and didn't understand why they didn't help when they were hanging right behind the robber.
  • The title character in the Doctor Who story "The Celestial Toymaker". Lose his games and you become one of his toys. Win and he destroys the world. By the way, he cheats a lot.
    • The Master (Simm edition) in Doctor Who giggles, makes faces, takes a childlike pleasure in the Teletubbies, and dances around the room to pop music while taking over the world and ordering the annihilation of millions of people. His Toclafane ( humans from the far future) are floating balls that are childlike, and kill "because it's fun".
    • The Gods of Ragnarok in The Greatest Show in the Galaxy are extremely powerful beings who have been completely consumed by the desire to be entertained 24/7 (or whatever Segonax's day is). One of them even manifests as a child.
    • Melody Pond. She gets better.
  • Dollhouse has Terry Karens, a wealthy serial killer who loved to "play house" by paralyzing and posing his victims like dolls.
    • Topher in the first season probably qualifies. (He starts to develop a bit of a conscience later in the second season.)
  • Fringe's Walter Bishop is a seemingly harmless Mad Scientist and pretty likeable, until you remember he experimented on children in order to communicate with other dimensions, has created horrible monsters and oodles of other universe smashing stuff.
  • King Joffrey Baratheon of Game of Thrones is slightly older than his book counterpart, but is highly immature due to his upbringing. He constantly engages in petty cruelty and takes sadistic delight in murdering, torturing and humiliating those beneath him even when doing so would be to his detriment, but behaves childishly towards those who stand up to him, usually resorting to screaming "I AM THE KING!" When his grandfather and Hand of the King Tywin dismisses him to his chambers for insulting Tywin, Joffrey actually responds with "I'm not TIRED!"
  • Psycho Electro Company assassin Elle Bishop from Heroes.
    • Sylar himself is a Type C. He's shown to be extremely powerful and ruthless, but also indulges in childish behavior to deeply freak people out. He's also shown to treat abilities like a toy collection, even explicitly calling Maya a shiny new toy to play with.
  • Jackman's Hyde persona from Jekyll is repeatedly stated to be a child who just happens to have the intelligence and drives of a full grown man.
  • Kamen Rider OOO has three of these. Kazari, a childish Chess Master, Gamel, whose a little lacking on the "psychopathic" part but still a destructive and childish kaijin, and Lost Ankh, Ankh's body that obtained sentience and has the mind of a child, but is none the less evil and destructive.
  • Law & Order: Special Victims Unit gets one in its tenth season with CSU Tech Dale Stuckey; in the season finale, Stuckey kills several innocent people to try and frame a psychotic man who'd killed before, kills his CSU boss before he can tell the police he was the actual killer, and starts assaulting Stabler with the intent to kill him before Benson makes the save.
    • One flasher-turned-child rapist is a severely stunted man who knew he had a problem as a teen but his dad used it (and his cameras) after having his son watch him with prostitutes, than watching his son with prostitutes wasn't enough to get him off. Olivia feels very, very sorry for him.
  • Reese from Malcolm in the Middle.
    • Hal says it best in one episode: "He has no more sense of right and wrong than a treefrog."
    • Arguably Francis from the same show.
    • Definitely Hal, if Lois isn't there to keep him in line.
    • Not that Lois is any better considering how easily she throws childish temper tantrums.
    • Since this is a Sadist Show, maturity is in very short supply among the adults and children of the cast.
  • Cyril O'Reilly from Oz, an Irish gangster who became retarded after a blow to the head. He also has the bad luck of having a Manipulative Bastard brother whose orders land him in jail. Though he's normally quite good natured, he becomes one of the more feared inmates as a very strong man who's easy to set off.
  • Gem and Gemma from Power Rangers RPM are a rare heroic example. They're intellectually geniuses, but in everything except physics and technology, they're about five.
    • They are also really fond of violence in general, and explosives in particular.
  • Joey Heric of The Practice was sociopathic, calculating and exhibited a very childish attitude such as announcing "I need to pee" to stop a trial session to get his way out of his own murder trials.
  • Jay Wratten of The Shadow Line is an example of Type C. He's an extremely dangerous man and his outward childishness only makes him creepier. He also turns out to be much smarter and more manipulative than anyone realises.
  • Moriarty in Sherlock is this trope in spades (type C). This is in deep contrast to the Moriarty of the original stories by Sir Arthur Conan Doyle.
  • Star Trek: The Original Series episodes:
    • "Charlie X," full-stop. A human child raised by omnipotent aliens and given the ability to warp reality. Though 18 years old, he has the social skills of a spoiled five year old. Having committed mass murder before being picked up by the Enterprise, he causes so much carnage upon the crew (which the aliens ultimately undo) that he is handed back to the aliens at the end of the episode.
    • "Whom Gods Destroy" involves one of Kirk's heroes gone insane from a head injury during a starship crash. Imprisoned in an institution for the criminally insane, he starts screaming at the top of his lungs and banging his fist on the floor when he can't impersonate Captain Kirk well enough to be allowed onto the Enterprise. Most other patients exhibit this trope. They exhibit "entertainment" to Kirk in the form of wheelbarrow racing in a circle. One patient defends accusations she plagiarized a poem from A.E. Houseman by saying she "wrote it again this morning" and craves attention from all the other inmates. The hero in question was played by William Shatner.
      • But only when the once-hero-gone-insane is impersonating Kirk, yes? If not, then someone's incredible make-up skills should also have been put to use in "Arena" (for starters).
    • Trelane of The Squire of Gothos starts out merely childish, becomes villainous (but still childish) when crossed... and ultimately turns out to be a child. Not a human child (his species is apparently far beyond humanity), and he appears as an adult human, but still a child whose parents come to pick him up, apologize for his misdeeds and punish him when he's been naughty.
    • Another Star Trek example, this time from Star Trek: The Next Generation: The Q race at times comes across as this. Omnipotent and godlike in power, while gleefully using their power to manipulate, bully and otherwise annoy "less evolved" species, while reacting with indignation when these species actually call them out on their behavior. The Q played by John DeLancie, with whom the crew most-frequently interacts, has a particular reputation for this sort of behavior even among his own people and is very much The Trickster. Except when he runs into Ben Sisko, who unlike Picard is not about to put up with his crap and outright decks him when pushed too far. His son takes it Up to Eleven.
  • Lucas Taylor in Terra Nova seeks to destroy Terra Nova and the world in which it is located killing over a thousand innocent people, all because he wants to get back at his father for not saving his mother when he was a teenager and generally not giving him enough attention growing up proving that being a genius scientist is no bar to living up to this trope.
  • Klaus and Damon on The Vampire Diaries. Both are reckless, ruthless, sociopathic yet somewhat immature at the same time.
  • Franklin from True Blood plays this trope straight off into the distance.
  • Emperor Cartagia from Babylon 5 is thouroughly insane and monstrous, but his cruel antics have a distinctively petty and childish taste. He's like a dim-witted bully tormenting a cat. He would dance a merry dance with the court jester and then have him executed for mocking him, goes all sulky when despite all his efforts, he cannot get a scream out of his victim, and acts annoyed that he has to make all the decisions, when asked which of the victim's eyes he would like to be put out. He sentences his planet to destruction, because he was promised to be made a god if he does.
  • Paulie Walnuts from The Sopranos is the perfect(ly nightmarish) combination of the petty self-centeredness of a spoiled child with the total disregard for human life of a stone-cold murderer.
  • Marlowe Viccellio from Psych. Apparently a normal woman when we first meet her, she is arrested for stealing blood (it was to save her brother's life) and sent to a California women's prison, where she quite abruptly turned into this. Given the nature of the show, this is Played for Laughs, with a scene of Marlowe acting cute and flirty with her boyfriend (ironically, a police detective) when he comes to visit her and then, seconds later, joining the rest of the inmates in a violent attack on the guards when they start a riot during a prison variety show. Later, when she is released from prison, Marlowe proves to be perfectly sane; her "crazy" shtick had been an act to endear herself to the other inmates - which is more heroic than it sounds, because the detectives needed her to cozy up to Santa Barbara's most notorious female gangster in order to uncover some clues toward solving a gang shooting.
    Marlowe: (sweetly to Carlton Lassiter as the riot begins) Duty calls. (viciously, into the crowd) I will cut you, Debbie!
  • Helena from Orphan Black is an especially creepy version of this. She has some mannerisms of a child (curiosity, Big Eater tendencies, somewhat childish way of talking) and is just all-around weird. Unlike most examples though, she knows just how dangerous she is. She's just that screwed up. She leaves clues that lead the police profiler to conclude that she had a bad childhood: mutilated dolls, bloodied paper fortune-tellers, stick figure sketches. She also plays on the bed when she breaks into Beth and Paul's apartment, eats jello with extra sugar, and wants to see Olivier's tail. None of this diminishes how threatening she is and how far she's willing to go to "cleanse" the other clones.
    • Softened slightly in season two: we see her bonding with her sestra Sarah (particularly the "Sugar, Sugar" singalong during the brief road trip) and the other clones, finding a "boyfriend" in a chivalrous bar patron, and showing kindness to other girls and women who have been mistreated in the same ways that she has. That being said, she still resorts to violence at a moment's notice and takes brutal revenge on those who have wronged her.
    • Another, more understated example is Rachel Duncan, the "proclone." Whenever something doesn't go her way, Rachel reacts with petty spite. Whether it's coercing Paul to have sex with her to get back at Sarah for killing her moniter/lover (even though Helena killed him), denying Cosima medical treatment in order to punish Sarah for being uncooperative, or petulantly smashing the vials of Sarah's daughter's bone marrow like a five year old breaking her sister's toys when Sarah doesn't give her important information (that she doesn't even have). Her grudge against Sarah is essentially out of pure jelously for taking away attention from her and for being the only known fertile clone.
  • Once Upon a Time: Rumplestiltskin/Mr. Gold is most definitely an emotionally immature version of this with his masterminding grand evil plans to get what he wants from everyone, his deal making, and chronic addiction to dark magic, being used as "mask" to cover up his fear of abandonment and deeply seeded insecurity and belief that he is unworthy of true love and that no one could ever love him that appears to go all the way back to his dad abandoning him as a kid on Neverland for eternal youth. He's definitely closest to the type three evil genius type manchild who's obsessed with power. However, he gravitates from both ends of the spectrum of both good and evil. Even his evil and psychopathy seem to be more based on the curse's dark influence, rather than Rumple, himself. Taking back the curse in 5x11 was completely out of the blue with no lead up or explanation at all, and it seemed less to do with a lust for power and more to do with rash traumatic survival instinct and a deep desire not to go back to Hell a second time after having been there once before his resurrection where he had no good memories a second time around. I can't really say he did anything wrong by taking it back, he just made it so Hook lost the chance to die a "hero" by destroying the curse. But Hook was basically a dead man walking, anyway with the Excalibur wound being reopened up when Emma cut him, so I don't exactly see how Rumplestiltskin did anything particularly good or evil when he took the curse back, just stupid and human. The writing seemed to convey that it was this dark plan, but the creators of the show A&E (Adam Horowitz and Eddie Kitisis have said otherwise in interviews.
  • Justified: Coover Bennett is the classic "Dumb Muscle bruiser" type. Very dim, and possessing the emotional range of an eight year old, Coover's life is built around pleasing his mother and brothers, and he throws violent tempertantrums when he can't get his way. His older brother Dickie is a slightly more mature example, who is psychologically trapped at the moment in high school when protagonist Raylan Givens broke his knee, leaving him with his trademark limp.
  • Supernatural:
    • Lucifer, for all his power, wisdom and affable evilness, is revealed to be nothing more than a "bratty child throwing a temper tantrum". His destruction of the human race is due to him being jealous that God favored humans more than him, essentially making the Apocalypse one big family argument.
    • Lilith, who possesses young girls and torments/slowly murders their family for fun. It's a common fan theory that this is because she was a human little girl before Lucifer corrupted her soul.
    • Metatron is a mix of Types B and C. One angel who refuses to follow him points out to him that even though he may have been able to get the better of everybody in the S8 finale, cast all the angels out of Heaven, and essentially become their new god afterwards, he's basically just a nerd trying to fit in with the popular kids.
    • The Trickster/Gabriel is a Type E, having a mastery of every kind of Deadly Prank and torturous mind game.
    • Rowena. While great in terms of raw magical talent, she wields her powers like a kid who's just found his dad's gun. In "O Brother, Where Art Thou", she sees Lucifer in his cage and acts like a teenage girl meeting her favourite celebrity.
    • The Darkness looks and acts like a human child for most of her appearances. She's also the original source of evil in the Universe, The Anti-God, and the one being that even Death himself fears.
  • The Walker, Texas Ranger episode "Deadly Vision" involved a man who abducts children to play with him, he would claim them as his own and kill anyone who tried to take them from him, and if the children angered him enough he would murder them.
  • In M*A*S*H, Major Frank Burns is an extremely emotionally immature individual, who repeatedly acts in ways not too dissimilar to a young child — up to and including throwing an honest-to-god temper tantrum when he finds out he won't get to remain commanding officer of the 4077 after Colonel Blake is killed. He's also capable of extreme acts of self-centered malice and cruelty, such as laughing at the possibility of his rival Captain Hawkeye Pierce getting executed for a court martial and being willing to steal a wounded General's gun and let the company clerk take the blame for it.
  • In Hannibal, the title character Hannibal, despite being cultured, cunning, and a strategical genius, regularly displays downright petty behaviour, for example making veiled confessions to the FBI agents he's toying with or killing people because they insulted him.His main motive for his crimes seems to be curiosity, as he says: 'Occasionally, I drop a teacup to shatter on the floor on purpose. I’m not satisfied when it doesn’t gather itself up again. Someday perhaps, a cup will come together.' He just 'wants to see what happens'. At some point, he shows mannerisms that resemble a child in an unsettling manner, like toying with a pencil, deliberately pricking his thumb on a fishing hook, then sucking the blood off his finger, or his childlike happiness about seemingly meaningless, little things.
  • While a tad more sympathetic than her book counterpart, Cersei Lannister from Game of Thrones is still at heart a very immature person prone to cruel and petty behavior. She has even thrown honest to goodness tantrums like a petulant child when things don't go her way. Actress Lena Headey says that she plays Cersei as if she was a wayward 15-year old who never had any real parenting.
  • Delete: The AI comes off as this, since it's essentially a young child lashing out at those it views as a threat.

    Music 
  • The main character of the Thomas Fersen song and music video "Hyacinth".
  • Maxwell Edison qualifies as Type C on The Beatles song "Maxwell's Silver Hammer".

    Pro Wrestling 
  • George Steele, during his heel run. He then became a sympathetic baby face, all without really changing his in-ring style.
  • The gimmick of Abyss in TNA is this trope. When he's a face, the sympathy is milked for all it's worth.
  • Poor, poor AJ Lee. The Ambiguously Brown cutie was never the same after Daniel Bryan publicly dumped her (although that blow to the skull she took from The Big Show when he nearly broke her neck during a title match with Bryan might also have been a factor), and she quickly descended into a morass of self-pity and highly erratic behavior that eventually turned dangerous. Among her frightening deeds are making sexual advances toward every man she comes across, wearing a red leather mask similar to Kane's, putting both Bryan and CM Punk through a table for no apparent reason, and...skipping around girlishly in short shorts and a bikini top, although her skipping around during a tag match seemed so out there that even Kane told her that she was too crazy even by his standards.
  • The Great Khali is this by default (Type A) during his heel runs. In-universe, he's a gigantic, physically and mentally stunted Indian immigrant who usually just wants to kiss girls and dance to Bollywood musical scores, but unfortunately is just so stupid that it's relatively easy for his much more evil "friends" to warp his mind and turn his phenomenal physical strength toward malevolent purposes. The last of these slavemasters was Jinder Mahal, who not only mentally manipulated Khali but idiotically tried to physically bully him as well, leading to the Crowning Moment of Awesome of Khali finally getting thoroughly sick of Mahal's bossiness and brain-chopping him into submission.

    Public Domain Characters 
  • Most depictions of Frankenstein's Monster follow this trope. (Although not the original version.)
    • In Mel Brooks' Young Frankenstein, on the other hand, he's a standard-issue Manchild (at least until the end, where he... ah... stops being anything of the sort). On the other hand, he does come across as being smarter than some of the other characters....
      • Not exactly setting a high bar, there.
  • The Minotaur is sometimes presented this way, especially in Jim Henson's The Storyteller.
  • In Dracula, Mina Murray draws upon the new science of Criminology to profile Count Dracula and describes him of being of the "typical" criminal mind- childish, in thought and behaviour.
  • Satan occasionally gets this portrayal, typically when interpreted as God's rebellious (and possibly abused) creation who desperately wants the Heavenly Father's attention. This has become especially common recently, and can easily integrate with any moral alignment (or lack thereof).

    Tabletop Games 
  • Apply this trope to a species, add a healthy dose of More Dakka and Clap Your Hands If You Believe, let (rule of) cool, and you've got the Orks of Warhammer 40,000. They think that they should do "wot's fun." It's just the rest of the galaxy's bad luck that to the Orks, "fun" means "NEEDS MORE DAKKA! Dat's 'ow ya killz fings!" They're like big, green, comic relief howlers.
    • Possibly Ogryns as well, given their fierce loyalty. See Gav and Bob for a Tear Jerker example.
    • Of all the violent raving madmen in this universe, fandom chose to make Ax-Crazy Blood Knight Kharn the Betrayer this of all people. Read this collection to see the Champion of Khorne (what a fun guy) engage in activities like finger painting with blood, arranging bodies into amusing messages, and jumping into combat from high orbit (the narrator ended up surfing a Khornate Space Marine).
    • One of the Iron Warriors short stories has the Slaughterman (type one), who is described specifically as having a child's unthinking cruelty. He doesn't come to a good end.
    • Lucius the Eternal, in Horus Heresy material, is extremely childish, selfish and petulant. He betrays the Loyalists at Isstvan III not because of personal ambition or some epic injustice, but because they don't like him as much as Saul Tarvitz, the man who saved all their lives by bringing a warning. He falls under type two, with a great degree of personal skill but absolutely no personal maturity.
  • Goblins in the Pathfinder setting have this kind of persona. They're such immature, comically inept little guys that they'd count as Ineffectual Sympathetic Villains if not for their rare moments of competence at murdering innocent noncombatants. In fact, each of the goblinoid races in Pathfinder (goblins, hobgoblins and bugbears) are meant to represent a different kind of evil and the little buggers represent childish random malice incarnate.
  • One of the most frightening and powerful incarnations of this trope is seen in the Dungeons & Dragons Demon Lord Kostchtchie, who rules a whole layer of the abyss based soley on sheer power and child like rage. It helps that he's secretly a pawn to Iggwilv, but still, most Demon Lords can't rise to the position, let alone hold onto it, without having shades of the Magnificent Bastard.
  • The Fair Folk of Exalted are mostly this. They don't mean to be horrible, horrible monsters, but they don't understand how reality works. They hail from the Wyld, where most any being they encounter is simply a figment of either their imagination or another Fae's, so they have difficulty processing the idea that every individual they meet in Creation is an independent and sentient being. Furthermore, in the Wyld, Death Is Cheap. A Fae killed by another Fae can just shape himself back into existence with a thought, so they have trouble understanding why the Creation-born are so uptight about the stabbing.

    Theater 
  • Poison in Dracula: A Love Stronger Than Death is a female example, a fully-grown vampire woman who affects an infantile attitude and carries around an identically-dressed doll while wearing babydoll dresses herself, and takes childish delight in the evil that comes with being a vampire.
  • Some productions of Shakespeare's Richard III will portray the titular character as one of these—despite his ruthlessness and willingness to kill everyone who might keep him from the throne, Richard is really just an emotionally stunted man who is jealous of his more popular brothers and wants to play with their toy (the "toy" being the throne of England).

    Video Games 
  • Lance Vance in Grand Theft Auto: Vice City Stories. He is an adult and a drug dealer, and is probably the only character in the series, at least in this sequel, acting childish, but nevertheless, is a sadistic murderer.
    • Catalina in Grand Theft Auto: San Andreas is a rare female example, Type B to be exact. Aside from being a complete psycho, she throws a tantrum over minor flaws, whines when one of her robberies with CJ fails, and changes her mood in the most arbitrary manner, all like a spoiled 13-year-old brat.
  • The Boomers in Gears of War and other Locusts of his size. The other locusts use cover effectively and yell orders to each other. The Boomer stands out in the open, points his gun in the general direction of the enemy, and dutifully says "Boom" before firing. That's all he ever says.
    • The oh-so-bland "SKY FIRE" when you fire a mortar.
    • The heroes themselves can come off as the "perpetual teenager" versions of this at times - especially Cole who (among other things) hijacks a Reaver and names it "Horsey".
  • Ramon Salazar of Resident Evil 4 has the build and proportions of a nine-year old, the skin of a sixty-year old, and claims to be twenty. He's also fucking nuts and suffers a severe Villainous Breakdown over the course of the game.
    • A less hilarious, more tragic example would be Lisa Trevor. After decades of Umbrella experiments, she's a powerful, seemingly unkillable monster with the faces of some of her victims sewed together and worn like a mask. Despite all this, her mind is that of a very young child, desperately searching for her mother.
  • Arguably GLaDOS of Portal. Her demeanour and behaviour certainly brings to mind a surly child, doing mocking impressions of Chell ("That's you! That's how dumb you sound!") and giving childish retorts ("If you love it so much why don't you marry it? Well, I won't let you!).
    • The turrets and their child-like voices. "Hello, friend. I see you. Are you still there? Good night. Put me down! Malfunction. I don't blame you..."
      • "No hard feelings..."
    • GLaDOS also smacks of a naggy mother taken to the logical extreme, neatly encapsulating both extremes in one package.
    • And GLaDOS' creepy red core, which personifies Wrath. Her yellow is curious ("Do you smell something burning?") her blue rattles off cake mix...plus other things ("Don't forget food garnishes such as: [...] fish-shaped dirt.") and the red is...er...well, it doesn't speak—instead it snarls and shrieks at you.
    • Wheatley, by the end of Portal 2.
  • From MOTHER 3, Porky Minch, the Pig King. Justified in that he extensively travelled through time after the end of EarthBound and only aged outwardly - he even describes himself as possibly being 10,000 years old or even older, yet still being the same kid inside, though he said it with the implication that that's somehow a good thing.
    • In Mother: Cognitive Dissonance Giegue is interpreted as the intelligent variant. While he's generally cold and calculating, he's prone to childish gestures like covering his ears when scared as well as throwing violent outbursts towards his own minions. His plan of gaining more power and use it to lay waste to Earth is essentially a temper tantrum over his grief over the loss of his loving parents when he was a baby and despair caused by their great grandson rejecting him, leaving him without a family.
  • Debilitas, the hulking gardener from Haunting Ground, is the only one of the stalkers pursuing Fiona who doesn't have overtly sinister motives - he mistakes her for a 'big doll' and just wants to play. Unfortunately, his idea of playing is a little too rough for poor Fiona...
  • Achenar, from the game Myst, has a childish way of relating horrific thoughts and events to the player, even speaking in a mocking, higher-pitched voice and giggling like he's just thought of some ridiculous joke. The effect is unnerving, to say the least.
  • The Igniter bloodline from Bloodline Champions has animations that give one this feeling about them: their running animations looks like skipping, their standing animation is them strangely tilting their head to the left with their right palm up, and their idle animation is hopping up and down left and right on the spot.
  • Walter Sullivan from Silent Hill 4. He kills people because he believes that he can resurrect his "mom" that way. Said "mom" is in fact a room in an apartment complex - his birth mother abandoned him there when he was a baby.
    • Eddie from Silent Hill 2 also works.
      • And, while more tragic than psychotic, Angela Orosco. She routinely flips between being a normal woman, a suicidally depressed woman, a psychotic and hateful woman, an innocent child and a psychotic and terrified child. Sometimes in the space of less than a minute. But given what her father did to her it's not that surprising.
  • Mimi of Super Paper Mario is outright called such by the Exposition Fairy Tippi. She's a bratty and selfish shapeshifter who looks like a little girl, but her actual age is indeterminate.
  • Chesty, from a Fable II sidequest, takes the concept of Nightmare Fuel and cranks it Up to Eleven thanks to having this personality...including not seeming to understand that his new "Super Best Friend" really isn't having fun during his Monster rush.
    • This super best friend had fun. She felt lucky to be able to do it twice thanks to a bug.
      • This super best friend was particularly happy when the game gave him back his lost youth.
  • The Legend of Zelda:
  • Undertale: Flowey is a selfish, petty Troll who delights in using his Medium Awareness to taunt the player. That's because he's actually Asriel Dreemurr, a monster who died while he was a child and Came Back Wrong in the worst way. He claims to want to become a god, but what he really wants is to trap the player in a Hopeless Boss Fight so that they'll be forced to play with him forever.
  • The Pyro from Team Fortress 2, of the Innocent Inaccurate variety.
    • Many if not most of the TF2 characters have shades of this.
  • Shadow from the Sonic the Hedgehog series is an adorable little boy. He looks up to his friend Maria, whose terminal illness he was created to cure. They reflect on what life must be like on earth. Even after her death, he shapes his life like a fairy tale, would do anything Maria asked him, and often whines pitifully about who he is and what he's there for. He also thought that the peaceful Maria would want him to avenge her by destroying the planet, is obsessed with his status as the ultimate lifeform, values human life and happiness very little unless he associates it with Maria or himself, and loves guns.
    • YMMV with Shadow. Still, it's possible; seeing the one person who supported him the most and who he saw as a moral figure murdered in front of his eyes probably disturbed him to the point of becoming this trope.
    • Despite being an Evil Genius, Eggman is very immature. He's prone to temper tantrums whenever Sonic beats him or when things don't go his way, and several of his bases throughout the series are giant amusement parks.
  • The Witch from Left 4 Dead sits there sobbing until and unless you bother her, at which point she has an unfortunately lethal (to you) temper tantrum. Then, once you're dead, she cries and runs away.
    • Ellis is just WAAAAAAAY too happy during the zombie apocalypse. It's almost as if he views it as a big game Unless someone dies
      • "Ho-lee-SHIT guys! It's KIDDIE LAND!!!"
      • According to Nick, "He's like a five year old. With guns. And a comprehensive grasp of every swear word in the English language."
  • The XT-002 Deconstructor fight in World of Warcraft is a robot version of this. When you aggro it, it says "New toys? For me? Oh, I promise I won't break them this time!"; when a player is killed during the fight, "I guess it doesn't bend that way!" and "I think I broke it!" and one of its attacks is it pounding on the floor shouting "No, NO, NO, NO, NO, NO, NO, NO!", all in the voice of a small child.
    • Background material indicates that Mimiron (his also-robotic maker) considers XT his son and, as such, built him to have a childlike character. It kinda justifies XT's childishness but not his Axe Crazy.
      • Mimiron himself mildly shows tendencies of being one. Not as a whole but some of his comments ("MEDIIIIC!") give a good idea about why XT was built the way he is. Unlike the most versions of this trope, however, Mimiron is a borderline genius.
      • Borderline? He's the god of invention.
      • Well to be fair at this point he is borderline, as all the bosses in Ulduar are Completly bonkers, thanks to good Old Good old Yoggy, being the Old God of Death and his powers being the power of inducing insanity into living beings.
    • Many of the undead abominations (giant bloated zombies made from multiple corpses) count as well. Patchwerk is well-known for his creepy childish lines:
      Patchwerk: "Patchwerk want to play..."
  • Jackle from NiGHTS into Dreams... is a literal psychopath whose lair looks like a small child's play room; complete with teddy bears, a merry-go-round, and a guillotine.
  • Tira from SoulCalibur is more or less Type E. She has such an extreme case of bipolar disorder that it has separated her into two personalities: "Jolly" and "Gloomy". When "Jolly", she talks like a little girl and refers to people as if they are playthings, and gets a thrill from breaking them in the most perverse and sadistic ways, as evidenced by her win quotes. When "Gloomy", she becomes extremely cynical and is willing to harm herself to inflict damage on her opponent.
  • John DeFoe of the Chzo Mythos is essentially this, seeing as he was raised alone in the basement of DeFoe manor after being disowned by his father, whom he considers an abomination and resposible for his wife's death. Being posessed by the Tall Man after he was beaten about the head and neck with a wooden idol containing his soul certainly didn't help.
  • In Tales of the Abyss, despite being at least 16 Arietta acts like a small child and apparently cannot handle the news of her beloved Ion death so they lied to her and said that the clone was him. She is also one of the fiercest fighters and one of The Woobie (but they are pretty common in this game)
  • We have The Beloved in Bayonetta. Big and stupid with cherubic masks on their hideous heads. There are no pretty angels in this game.
  • Shin Megami Tensei: Persona:
    • Chidori from Persona 4 fits this to some extent. She has a fairly simple vocabulary for the most part, hasn't the faintest idea of how to deal with falling in love, and throws some pretty impressive temper tantrums when deprived of the gun-like Evoker she seems to treat as a comfort object. On the flip side, she works nights enacting revenge for people and has no problem with committing the occasional bit of telepathic breaking and entering.
    • Persona 4: The true killer, Tohru Adachi, is revealed to be one after he's exposed. For starters, both of his initial murders are for extremely petty and childish reasons; he first one was just him throwing a temper tantrum because a celebrity he had a crush on had an affair, and the second was just because he saw a high school girl talking to an older man and deemed her a "whore" who had to die. From there, it devolved into simply killing For the Evulz. The Investigation Team even flat-out call him nothing but an immature brat throwing a temper tantrum.
    • Sho Minazuki, one of the main villains of Persona 4: Arena and Persona 4 Arena Ultimax, is the same age as the Investigation Team members, and so psychotically immature that Adachi himself outright calls him nothing but "a brat throwing a temper tantrum."
  • Whether he admits it or not, Terumi Yuuki from BlazBlue lives this trope. In essence that he's only got one thing in mind: Make the world run like he idealized where he's considered the most awesome being in the world and everyone believing despair to be the only truth. And because the world, as much as it's such a Crapsack World, didn't work like that, he's trying to modify it by force instead of adapting, like a little kid throwing a cosmic temper tantrum because his daddy didn't give him the toy he wanted. Also his methods aside of sadism include childish mocking and appealing by brute force if Mind Rape was not enough.
    • Central Fiction reveals another surprising candidate: Hibiki Kohaku, Kagura Mutsuki's Battle Butler. His likes include Japanese confectionery, and he notable has a youthful appearance. He's also a deeply disturbed individual, but tries to hide it.
  • No More Heroes has Bad Girl and Destroyman.
    • Matt Helms in No More Heroes 2: Desperate Struggle. He's an undead who in his childhood made a deal with the devil, resulting in him going crazy. And all through his battle he laughs like a little child.
  • Half the cast of the Touhou says "hi". In particular, Flandre Scarlet, a vampire that looks like a little girl with the explicitly-defined power to destroy anything and a love for games that involve breaking her "toys".
  • Adachi from Persona 4. Don't call him that though. He doesn't like that at all.
  • The Demiurge is portrayed this way in Shin Megami Tensei: Strange Journey. He never ceases to scream when addressed, knocks out Metatron, not caring he's got the Pieces of God necessary to restore his mind, and keeps bellowing he wants worship and praise as the Creator.
  • Grunt from Mass Effect 2 shows shades of this. At one point, he talks about killing the other "weaker" species, all the while pointing out how funny that would be with a child-like glee. He also likes sweets and plays with action figures. However this is justified for two reasons. He is a krogan, and being Ax-Crazy Blood Knights is a major part of the krogan hat. Also, he was grown in a vat and is less than a year old.
  • Purge from Space Channel 5 Part 2. He likes to play "games". And as heroic characters such as President Peace and later Jaguar are unwillingly forced to take you on, he just laughs and at one point even DANCES happilly as they struggle in pain. He even goes as far as to have a temper tantrum and charges up the Ballistic Groove Gun to destroy everyone, including himself for ruining his plan. The game hints that he doesn't know love somehow, but it still doesn't keep it from being slightly disturbing.
    "Time for a game! If you shoot like normal, you'll hit the president!"
  • Isometric Third-Person Shooter Loaded has Mamma, so named because it's the only word he knows. A hulking, diaper-clad giant prone to inadvertently crushing people to death, his backstory indicates that he was abandoned as a baby, but somehow survived to adulthood without acquiring any education or social skills.
  • Albedo from Xenosaga, especially with his interactions with MOMO and Jr. In the first game, he giggles at the sight of a Kirschwasser he tore apart and demonstrates his ability to regenerate as if he was performing a magic show.
  • Kefka from Final Fantasy VI was written as one of these in the original, Japanese script. He uses the first person singular verb "bokuchin", which is what little boys use when joking around or trying to act sweet. This idea was left untranslated in the English localisation.
    • A hint of this snuck its way into Dissidia: Final Fantasy, where he talks about battle as playtime during his fight with Terra, as well as his referring to his opponents as "toys."
    • As well as in Duodecim, where he remarks that his fight with Vaan was "The most fun [Kefka's] had in minutes." in an over the top, high-pitched, giddy voice.
  • Caesar in Fallout: New Vegas is Type C. Charismatic, smart, and drunk on the power he coveted since he was a child in the Followers of The Apocalypse. Reading the flavor content in the back of the Prima Collectors Edition Guide reveals that he was petulant and gloryhounding ever since he was a boy. And if you rebuke him during a face-to-face visit, he throws quite a temper tantrum. He's like the Last King of Scotland: He's childlike, that's why he's so scary.
    • Fallout 3 has Dr. Stanislaus Braun, the overseer of Vault 112/Tranquility Lane; having trapped the Vault residents in a virtual reality simulation, he's spent the last two hundred years using them as playthings for his own twisted amusement, torturing and killing them over and over again in countless gruesome ways. For good measure, in the VR's latest simulation, he's assumed the form of a spiteful little girl named Betty. Lastly, if you succeed in permanently mercy-killing his victims, Braun will throw a temper-tantrum over not having "anyone to play with anymore."
    • The dumber Super Mutants throughout the series, especially the Capital Wasteland ones.
  • General Sarrano, Big Bad of Bullet Storm is an example. Serrano's general character can best be described as "every stereotype about Call of Duty multiplayer at once."
  • Mileena has been repurposed as a Type E variant in Mortal Kombat 9. Possessing the mentality of a young girl, she giggles her way through fights and seems to see butchering people as a fun hobby. One of the challenges in the Challenge Tower consists of her trying to force Scorpion to take a teddy bear she made.
  • In Double Switch, Eddie seems to be this. He seems like a normal Nice Guy who is a genius. Unfortunately, he wants an Egyptian statue so badly that he will hurt or kill to get it. He seems to be bothered by what people say about him at some points. It is also pretty sad to see him reduced to crying "Mom! Mommy!" by the end of the game.
  • N from Pokémon Black and White seems to be one at first due to his association with the villainous Animal Wrongs Group and childlike behavior (gleefully dragging you to the Ferris Wheel because he's never been on one before, plus his playroom). Subverted! He turns out to be a Well-Intentioned Extremist Manchild with No Social Skills instead, and once you... convince him that Pokemon aren't really as abused as he thinks, he becomes quite friendly. And then you find out why he was that way to begin with...
  • Metal Gear:
    • Liquid Ocelot dips into this during the second half of Metal Gear Solid 4: Guns of the Patriots. He makes Finger Guns at the army trying to apprehend him in Eastern Europe ("Bang! Bang!"), and childishly taunts Snake as he makes his getaway after their fight on Shadow Moses.
    • Sundowner of Metal Gear Rising: Revengeance provides the page quote. He's emphasizing a child's capacity for cruelty rather than his own.
  • Dr. Angus Bumby from Alice: Madness Returns is a rather subtle version of one whose childish behavior doesn't become clear until well into the story. While, normally, he seems calm and well-educated, as the story unfolds it becomes clear that he's just a possessive child unable to deal with being told no after raping Alice's sister, Elizabeth, seeing her refusals as teasing and then covering it up by burning down their house with them inside. Even the Dollmaker, his Wonderland counterpart uses childish suggestive motions with his hands throughout its boss fight. And, finally, in the end he takes time to gloat at Alice over using his hypnosis therapy to brainwash children into prostitution, that he will get away with it, and continues arguing that he has done nothing wrong.
  • Edward Richtofen from Nazi Zombies is a type C.
  • Ignus from Planescape: Torment really likes fire. Including watching fire, setting other things on fire, and being on fire. His mind is also so damaged(being turned into a conduit to the Elemental Plane of Fire will do that to you) that he doesn't seem fully aware that other people don't share his enthusiasm for this.
  • The antagonist of Borderlands 2, Handsome Jack. Although he is intelligent enough to pull off some impressive Batman Gambits, he's also a completely deranged psychopath. Among other things, he laughs as he tells a story about gouging out a man's eyes in front of the man's children. Despite being the CEO of the most powerful Mega Corp. in the 'verse, he cannot resist calling up the Vault Hunters just to sling childish insults at them. He also brags about being rich enough to blow his money on a pony made out of diamonds, which he calls Butt Stallion.
    • There's also the Goliaths, slow-witted giants who apparently regard combat as "play time", and the psycho bandits, who ramble all sorts of nonsense (often about their mothers) as they try to kill you.
    • Mr. Torgue from the DLC pack "Mr. Torgue's Campaign of Carnage" is a likable guy, but he's very loud, loves cookies, is obsessed with explosions and manliness, and writes everything in crayon. He also bonds quickly with explosives-loving Creepy Child Tiny Tina.
  • The Brutes in Command & Conquer: Red Alert 2: Yuri's Revenge are mutated humans with an Incredible-Hulk like physique, who can kill tanks with their bare hands. They also have the mentality of a five-year old, look on fighting as "playing" and when damaged sob about how they want to go home.
    • The Grinder Tank introduced in Command & Conquer: Red Alert 3: Uprising is similar: they're weaponised steamrollers that can grind anything and anybody that crosses their path into a mangled mess. Their crew go about their work with the intelligence and emotional state of children, giggling about much fun it is to break their "toys".
    Who wants to play?
    We here to crush!
    Go tank! Go tank!
    He go bye-bye...
    Here I coo-oome!
    Make him look funny.
    I break all my toys!
    CRUSH THEM!
    Ouch! That hurts!
    They're picking on me!
    I just wanted to play...
  • The Boogeyman from Cause of Death. After a burglar (unwittingly) saved him from a lifetime of abuse by killing his parents, he recruited Eli to help in further burglaries. Eli, meanwhile, thought saving him from abuse was the whole point of Jeb killing his parents. So what does he do? He starts killing other abusive parents in turn. And he simply cannot get rid of the trappings of childhood, such as treehouses. He genuinely wants to befriend and play with the children he rescues (and no, those aren't euphemisms), but honestly can't comprehend that he's traumatizing them instead.
  • Jinx, from League of Legends. She is a hyperactive girl ostensibly in her late teens/early twenties with Girlish Pigtails who is just out to have some fun. Except her idea of fun involves lots of wanton mayhem and Stuff Blowing Up. Her main reason for coming to Piltover was because she thought the city had too much "pathetic neatness" and needed some buildings blown up. She names all her guns and occasionally has conversations with them.
  • The Advance Wars series has Penny from Days of Ruin and Lash from the other games. Penny's mind is so far gone she doesn't even have a grasp of good or evil, and can only be pointed at an enemy army and told "go play". Lash on the other hand definitely acts like one but can also act dead serious at the drop of a hat and is very cunning, and neither the player or the characters in the game can decide if it's an act or if she has a Split Personality.
  • Bobby Barrows, the original Scissorman from the Clock Tower series is a solid type B. He giggles playfully and dances for joy every time he overpowers you with his massive scissors, unless your health is low. Then he just impales you. The second Scissorman (Bobby's brother Dan) is much more of a type C as he's intelligent and capable enough to be a Manipulative Bastard.
  • Fawful in the Mario & Luigi series. He may be a genius Mad Scientist with world domination ambitions and be one of the villains in two different games, but he's also one of the most crazy, childish and overly unhinged characters in the franchise, with an attitude that can be summed up as this trope meets the Narcissist. He especially likes to chortle, laugh or joke about his plans and the presumed imminent demise of his enemies.
  • Scarlet Briar in the Guild Wars 2 is a type C. She is a genius who is behind many of the major storylines from the Living World's first season, but also treats her crimes as games and her victims as toys to amuse her.
  • Tenzan, from Super Robot Wars Original Generation, despite being in his 20s, thinks it's acceptable to act like a 13 year old Griefer playing Halo in a real war.
  • Dead or Alive Dimensions depicts the first Kasumi Alpha clone as a mix of Types C and D. She's very beautiful and is just as powerful as the real Kasumi, and yet is very immature and childlike, to the extent that she breaks Kasumi out her cell at DOATEC Germany with the intent to kill her and have Hayate all to herself. Her entry on the Dead or Alive Wiki explicitly describes her as acting like "a misguided child with too much power."
  • Peri from Fire Emblem Fates is not always on the player's opposing side (it depends on the route chosen), but otherwise is a perfect Type D: she's a cheerful, cute, naive older teenager with the speech patterns of a little girl (the Japanese version has her speaking in third-person)... but she's also incredibly violent in the battlefield, and likes murdering people with little provocation outside of it. She also has a pretty tragic reason to be like this: she witnessed her beloved mother's murder at the hands of a servant and the trauma completely broke her mind and heart.
    "I'm feeling stabby!"
  • Call Of Duty Black Ops III: Turns out, when you raise an artificial intelligence using the minds of fifty-four mind-raped criminals, the results are UGLY. At the end, Taylor explains that the AI is NOT a super-intelligent mastermind hell-bent on ruling the world, but an angry 10-year old kid who knows how to use advanced technology but has the hatred, short temper, and stupidity of a spoiled brat, which is why he's threatening to destroy the world for no real reason.
  • A type D/E appears in Way of the Samurai 4, at the end of the Four Samurai Lords VS Yakuza Quartet job-line. The titular Yakuza Quartet are a fearsome foursome of murderous, blood-thirsty gangsters, and through the missions leading up to your confrontation with them, you've met three of them. When you face off against them as a member of the Four Samurai Lords, however, their fourth, final, and most fearsome member finally makes an appearance... It's 'Manmaru', the mentally-retarded man you've probably seen running around town now and then, holding a pinwheel and generally acting and talking like a young child. Only, now he's wielding a blood-stained version of the hideous, barbed sword made famous by the terrifying Psycho for Hire, Kyojirou, from the second game - and merrily declaring his eagerness to 'play' with you. During the fight, he'll sound like he's having a great time, too... right up to the point where you cut him down, anyway. Oh, and since you never get a chance to find out what his deal really is, he's arguably a type F too. Considering that 4 takes place in the same town as 2, several decades later, it's not impossible that he's somehow the son of the aforementioned Kyojirou - or at least that the sword he wields actually is her old weapon.
  • One of the killers in the third part of Lakeview Cabin Collection has a child-like cry, wears an odd child-like mask, loves teddy bears (which can be exploited to get free hits on him), and just merely rushes at the player.
  • In Starbound, pretty much every Floran who isn't a Greenfinger. They're bloodthirsty, have a taste for sentient flesh, view the world through a simple, warped lens, and only just capable of empathy towards non-Florans. A "friendly" Floran is typically one whose violent tendencies are directed usefully. Just don't assume they're as stupid as they seem.

    Webcomics 
  • The Order of the Stick
    • Thog is a half-orc fighter/barbarian with extremely violent tendencies, a sunny disposition, and an Intelligence score that's probably no higher than 5. Thog is probably the only person alive who gets along equally well with Elan and Nale. Elan and Thog bond over the "Manchild" part, and Nale appreciates the "Psychopathic" part.
    • Though more intelligent than Thog, Nale himself falls into this trope once he stabs his own brother simply for not wanting to join his group.
    • Xykon, the Big Bad, an epic-level sorcerer who is trying to take over the world more or less For the Evulz.
    • Belkar Bitterleaf, who sorts the world into people he wants to stab, people he can't (yet) stab, and people he finds gratifying in the moment — and the categories overlap.
    • Remember how Elan used to be a benign Man Child? Well, his father General Tarquin devolves into an evil version of this once his Villainous Breakdown really starts kicking in and he vows to kill all of Elan's friends (and cut off his hand) just to get him to finally follow his narrative plan.
  • Richard from Looking for Group often shows childish tendencies and extremely bratty and whimsical behaviour.
    • Tim the ogre would be a textbook psychopathic manchild (he refers to Cale'Anon as "Chicken", ex. "Chicken needs squishy?"), but has been described by one of his associates as being taking one too many maces to the head.
      • Tim is certainly a manchild, but he is really not the violent psychopathic sort.
  • Sluggy Freelance:
    • Reakk: Even though he's a demon who eats people's souls, it's hard not to like the dimwitted little guy.
    • Oasis, with her underdeveloped personality and sadistic fondness of killing. Bun-bun described her as a "demented toddler", and while she's theoretically opposed to killing innocents, once she eliminates someone from that category, she's willing to do things such as cut their ribs out one at a time out of curiosity while they're still alive.
    • Agent Gnaaaw, a young woman possessed by a brutish demon, is childishly confused about the distinction between liking someone as a person and enjoying eating them.
  • Camille Domino of Bloody Urban, a century-old vampire who is extremely short, dresses like a teenager, throws hissy fits when she doesn't get her way, abuses her powers for selfish ends, and generally sees no problem in acting horribly towards other people.
  • Kharla'ggen of Drowtales is clearly insane and enjoys turning people into living dolls unable to move, but it's implied she's not actually that bad a person under her insanity. Being under the thumb of a Psycho for Hire who used her as a figurehead leader didn't help her at all.
  • In 8-Bit Theater, Black Mage is a rare example of a "heroic" Type C, in that he is intelligent and relatively well-put-together, but takes a psychotic, child-like glee from hurting close friends and innocent people for little reason more than the amusement it causes him. His tantrums tend to devolve rather quickly into childish whining as well.
    • Fighter is a Type A, who generally enjoys beating the living shit out of people, but is quite friendly and rather... slow.
  • Ethan from Ctrl+Alt+Del, who is almost completely bereft of maturity and/or responsibility, even from his own actions. He's Peter Griffin, except he's a gamer. Yup.
  • Lawler of White Noise could be considered this. He's a skilled, ruthless, cheerfully sadistic operative who's obviously quite a few bananas short of a bunch. Yet he has a child-like unquestioning devotion to his boss, and spends his spare time having fun by drawing all over his hands. Aww.
  • Spot of Get Medieval has a childlike enthusiasm for fire and explosions and pure hate for those who try to stop him from making either.
  • Jared of Jared, despite being very intelligent and a Badass, is childishly selfish and obsessive.
  • Butch of Chopping Block can be this, though the degree to which it applies varies wildly from strip to strip. In one case, his mutilation of corpses was compared to a child playing with a cardboard box.
  • Slick, the devil and God (!) show such tendencies in Sinfest.
  • Homestuck: Lord English, despite being the untouchable master of Weird Time Shit, is still the same surly Jerkass he was when he was young. Explained in-universe as the result of him putting a hit out on the dream self of Calliope, his sister/good personality, instead of doing a Split Personality Takeover as is normal for their species. Without her he was unable to mature properly, and we later his adult form (which always looked different from adult Cherubs, most noticeably in that he had no wings) isn't really an adult at all, but rather Caliborn fused with a few other characters, most notably the muscular Arquiusprite. It was his physique that made Caliborn appear as an adult. All this makes him a Type B.
    Land of Boredom and Confusion: HOW DO YOU GO FROM MURDEROUS PSYCHO DOUCHEBAG TO HILARIOUS DORK IN TEN PAGES. HOW.
  • Quant from Tower of God is a Ranker of the Tower, a position commanding great respect and implying a terrifying amount of power, which he does possess. His greatest weakness is his incredible immaturity, which not only let him self get lead on twice by the examinees he had to train and test, but also caused 197 people to die because he didn't give a shit about concocting a complicated preliminary exam and just settled with a 30 minute death match.
  • Schlock of Schlock Mercenary manages to combine this with Sergeant Rock to make for one dangerous blob of ambulatory goo. He's childish, violent, loves Stuff Blowing Up, can and will eat anything he can fit in his mouth, (including people) and the idea of having his hand-held rotary cannon effectively turned into a personal artillery field piece rigged to fire grenade rounds gives him a gleeful expression like a kid on Christmas. Oh, and for a brief period he was Dual Wielding sawed off starship cannons. He's by no means stupid, proving on several occasions to be a cunning tactician and combat leader, but his Blood Knight tendencies and immaturity guarantees he'll never be promoted above sergeant. And so long as he gets let off his leash to indulge in a bit of ultra-violence he's probably ok with that.
  • The titular Axe Cop has a sort of meta-justification in that he's actually written by a small child.
  • Agathoth from Cloudscratcher is described like so.
  • Dom of Plume acts like a bratty tween most of the time, but is also a ruthless and trigger-happy murderer.
  • Commander Kitty has Zenith, who, while very effective at creating Body Horror and a would-be Galactic Conqueror, and far from stupid, has approximately the personality of a self-obssessed Bratty Teenage Daughter: she's childishly jealous of her perceived rivals ("She gets her own button an' everything!"), insists that creating a perfected Mix-and-Match Critters Flesh Golem will advance her agenda when she really just wants a boyfriend, is afraid of bugs, etc. This doesn't last forever... unfortunately.

    Web Original 
  • The Angry Video Game Nerd showcases a bit of a Type F personality in his early-mid episodes.
  • In Alfred's Playhouse, Alfred Alfer has a Split Personality. Regular Alfred Alfer, is a manchild trying to repress memories of sexual abuse by imagining himself in the titular Playhouse whenever he was being abused or having a flashback. The psychopathic personality is Dictator Pickles, who is the part of Alfred's personality who had to take the abuse when Alfred was imagining himself in the Playhouse, and is now angry and vengeful. He wants to Take Over the World, hates Alfred, and shows no remorse for what he does.
  • Pretty Pink Ponytails from Angel Of Death is a twenty year old woman who has a high pitched voice, wears cloths made for small children (they're cut apart, and have extra fabric added to them.) She skips everywhere and loves to sing nursery rhymes. She also seems to enjoy torturing people and often describes things like death how a little girl would, despite seeming to comprehend these things fully. She also uses brightly colored handguns, and loves explosions.
    • It's not clear if she really thinks she's a little girl, feels compelled to act like a little girl, or is just taking on the persona of a little girl. If the latter is the case, then she seems to keep up the act 24/7, as she's never been seen out of character, even in private conversations with her brother.
  • The Emperor of If the Emperor Had a Text-to-Speech Device, when he's not Grumpy Old Man, has moments when he appears to be this.
    Holy shit, a giant skeleton space robot planet that shoots molecule-breaking beams and destroys everything it spots... I want one!
  • One possible interpretation of HABIT from Everyman HYBRID.
  • Blaine Eno and Cillian Crowe from Survival of the Fittest are each brutal killers brought onto the island specifically to spice up the competition (it's implied that the terrorists actually broke Cillian out of his asylum to take him to the island), but Blaine is mentally and emotionally seven years old and has no real grip on what he's doing, while Cillian is almost under the control of an imaginary, daemonic, friend named Haddy.
    • Lately Liam "Brook" Brooks has shown signs of being one of these after having some Sanity Slippage which resulted in Ax-Crazy tendencies.
  • Dragon Ball Abridged:
    • Nappa.
    "Look Vegeta...a Pokémon!"
    • Freeza comes off as intelligent and cool-headed at first, but when it comes down to it he's really more like a bored rich kid who gets his entertainment from killing innocent people. As he loses more of his cool, his immaturity shows.
    • Vegeta.
  • The title character of Salad Fingers, though this may be a subversion as he's more True Neutral in the "uncaring, detached, and having no regard for either good or evil" sense.
  • The Nostalgia Critic is a Type B. Imagine him as a twelve year old boy with no supervision and a gun and you get the idea.
    • The Nostalgia Chick is a Type D. You get the impression sometimes that she genuinely doesn't know why Nella would be pissed off about cameras placed in her bedroom. And there's no guilt involved either.
      • Elisa's characters Dr. Tease and The Makeover Fairy both enjoy torturing people through science and makeovers far too much.
    • Genki Girls Allison Pregler and Pushing Up Roses occasionally wander into this trope when their excitement gets a touch too extreme.
  • In the Agents Of Cracked webseries on Cracked.com, this is Michael Swaim all the way. He's a Depraved Extreme Omnisexual and Idiot Savant with a cheerful "just for fun" attitude who kidnaps schizophrenic women as his "wives." Reversed in Cracked's other content, where Swaim is a polite android, while D.O.B. and Brockway have the drug-fueled, destructive benders.
  • Every one from Profound Moments In Left 4 Dead 2 could count as this.
  • Dr. Wondertainment, considering the toys he/it makes.
  • Leslie, the Psycho Lesbian who showed up occasionally in the short-lived web series 3 Way. She stalked her ex-girlfriend, Geri, obsessively despite having been warned by a court order to stay away, making creepy phone calls and jumping out of random hiding places to frighten Geri. Yet, despite some of her acts of terrorism being inspired by those of fictional movie villains (Glenn Close's in Fatal Attraction, most notably), they are all of the Poke the Poodle variety. She also sleeps with a Big Bird doll.
  • Jalix 'Trap-Deezy' has shades of this, often exploding into tirades of excessive alliterative insults at people for even doing the most harmless of apparently "stupid things". Also having a fondness for cute things, littering his videos with inane babble and odd images and making videos where he almost always appears as an intelligent yet morally divorced teenager with world-views beyond his years and an aversion to people, watching his serious videos is just plain awkward.
  • The Downfall parodies' portrayal of Adolf Hitler is this. For starters, try telling him that his Xbox Live account has been banned for life.
  • Mr Deity is a Type C. He's a Jerkass God who deliberately puts all sorts of evil things into his creation for no real reason and frequently inflicts horrifically cruel punishments for minor crimes, but behaves in a very childish manner, particularly in the way he responds to criticism.
  • Nutty from Happy Tree Friends is a Type D, assuming he is actually an adult. He will do anything to get his candy, and while ordinarily he only hurts himself, there are exceptions, most notably "Class Act" where he begins eating Sniffles alive because Sniffles was wearing a candy cane costume.
  • Imaginee from The Autistic World of the Autist is a Type 2. He acts in a very playful manner when torturing people, gets really excited when his plans work (which they usually do) and frequently throws a tantrum when things don't go his way (then find a way to spite whoever foiled his plan).
  • The "tendies" 4chan meme features an austistic man living at home who terrorizes his family into giving him "tendies" (chicken tenders) in exchange for "good boy points".

    Visual Novels 
  • SHIKI from Tsukihime started off as a mischievous yet unstable kid...then his brutal awakening of his demon blood while simultaneously the Big Bad was taking him over from the soul outwards, impaling his Only Friend and being confined cracked his mentality to become this. Now as an adult, he's extremely powerful, but now he's prone to violent temper tantrums, self-centered, aggressively possessive and just plain creepy.
  • Ilyasviel von Einzbern from Fate/stay night whose child-like attitude is slightly justified by the fact that she was orphaned at a young age and never received anything even resembling a traditional upbringing. She's pretty, cheerful, carefree and has an attachment towards Shirou...but after being abandoned by her father and being raised as a Tykebomb Artificial Human with no concept of morality, she will toy with Shirou while pleasantly torturing him.
  • Regina Berry of the Phoenix Wright: Ace Attorney series is a rare example of a female Type A. Regina is the teenage daughter of a circus ringmaster, who raised her without ever letting her know about the outside world. As such, she has absolutely no understanding of things like death or pain—to her, everything is a game or a lighthearted practical joke. Unfortunately, this makes her completely (though unknowingly) selfish and cruel: she does whatever she wants to do whenever she wants to do it, never bothering to consider how her actions might affect the people around her. The biggest example of this is the fact that she inadvertently put one of the circus's trapeze artists into a coma by playing a prank on him, and repeatedly talks about how he's "sleeping" instead of being nearly brain-dead.

    Western Animation 
  • Ren from The Ren & Stimpy Show is the clearest example of this trope, behaving like an Ax-Crazy psycho, but behaving childish sometimes.
  • Aqua Teen Hunger Force: Master Shake constantly whines and throws temper tantrums, cares for no one but himself, and constantly goes above and beyond to torture Meatwad For the Evulz.
  • When Family Guy first premiered, Peter Griffin, though stupid and thoughtless, usually had good intentions behind his actions. Unfortunately, as time went on, flanderization set in and he's now degenerated into a type E motivated solely by self gratification regardless of the consequences to others.
    • Glenn Quagmire, Carter Pewterschmidt and Cleveland have become psychopathically childish adults in recent seasons.
    • Also Stan and Roger from American Dad!. To be honest, nearly every adult on Seth MacFarlane shows shows signs of this.
  • Futurama's Bender, the alcoholic, amoral gambler who deals porn and has no qualms with selling children as dog food occasionally becomes incredibly childish, most notably in the Mom-centric episodes.
    "Mom! Mom! Look at me, Bender! Hey-ho, I want attention!"
    • Though he is only four. At first.
    • Zapp Brannigan also counts. He's very cowardly, dim-witted, immature, narcissistic, and perverted. He's also a high-ranking officer in the Earth's military, with disastrous results.
  • Toyman of the DCAU, recreated as a childish madman who wears a doll head with a creepy smile.
  • The comic book sequel of Batman: Mask of the Phantasm implied that The Joker himself was a psychopathic manchild after his transformation. Despite Phantasm's hatred for the Joker, when he's finally caught at the climax, there's a moments hesitation as Phantams realizes Joker isn't the same ruthless mob hitman from years ago, but just a grinning lunatic, no longer capable of remorse, and motivated only by a desire for personal stimulation through murder.
  • Batman: The Animated Series has a rather Tear Jerker Deconstruction in "Baby-Doll"; The eponymous supervillainess is a 30 year old actress with a medical condition that causes her to look about five, despite having the emotional and intellectual maturity of her actual age. Because of this, she was never taken seriously beyond her original role in a sitcom and ended up being Driven to Madness, throwing up her Cheerful Child stage persona as a psychological shield against her miserable existence (though it isn't perfect-she slips up and reveals her true, depressive personality on occasion). The plot is driven by her attempt to recreate the show's setting in an attempt to return to the one happy part of her life. Her emotional immaturity is a mask to help her avoid her problems with adulthood, as revealed when she crosses the Despair Event Horizon.
  • The eponymous character of Invader Zim can edge toward this. His interactions with his leaders, especially.
    Zim: My Tallest! My Tallest! My Tallest! My Tallest! My Tallest! It's me! Look at me! My Tallest? My Tallest!

    Zim: But I must get my equipment or... I won't... get it.
  • Courage the Cowardly Dog: Eustace Bagge is essentially a Bratty Half-Pint in an old man's body; in the episode "Mother's Day," upon seeing that his Abusive Mom got Courage a teddy bear, he throws a temper tantrum and whines, "Why don't you ever get me anything?!"
  • Squidward from SpongeBob SquarePants. While he's generally reserved and keeps to himself, a lot of the time he's Not So Above It All and will join in on Spongebob and Patrick's antics, usually taking it too far. Probably the best example is "Snowball Effect", where he at first stays away from snowball fights and discourages them. After trying to manipulate them into fighting again, he starts violently throwing snowballs, causing Spongebob and Patrick to do the mature thing and leave the fight while he's reduced to a psychotic wreck.
    • Plankton also may count. It was in the early seasons an evil enemy, especially as he is seen in the film, but at least as seen in the episode "FUN", seems to have pretty a childish side with SpongeBob when he befriends him. And it is assumed that Plankton is almost as old as it is Mr. Krabs.
    • And SpongeBob himself in later seasons.
    • Patrick could also count, given how often his stupidity puts himself and those around him in danger.
  • Grimlock from Transformers Generation 1 is a Psychopathic Mech-Proto who regularly tries to defeat Optimus Prime for leadership of the Autobots, destroys Decepticons with pleasure and rules his faction of Dinobots with an iron tail... in his down time, he enjoys fishing with said faction, hearing stories about the Good Ole Days from Kup (in the middle of battles) and giving human children and annoying, rhyming Autobots piggy-back rides. He also has his own brand of Hulk Speak.
    • Speaking of rhyming Autobots, Wheelie might actually fall into this catagory. He fights about as well as any other Autobot and has taken down robots three times his size, but generally speaks in sing-song rhymes and hangs out with a 12-year-old human boy.
    • Galvatron in Season 3 definitely fits this trope, from treating potential mass murder as 'sport' and 'hunting season' for Autobots he acts like a child whenever he loses with the Decepticons taking the brunt of his tantrums. They eventually get sick of it and tell his loyal lieutenant Cyclonus to do something about his insanity.
  • The Warden from Superjail! puts the Manchild in Psychopathic Manchild. He acts his shoe size and is barely sane enough to keep his emotions together. For example, in the pilot as the Warden sings and pets a dead rabbit, he rips its skin off in a moment of unprovoked aggression, then promptly puts the bloody skin on his head and orders Jared to get bunny suits for the inmates.
  • The X-Men animated series' rendition of Kevin McTaggert aka Proteus. The cartoon took the character and made him a teenaged mutant with the mind of a young child after being locked away from the world by his mother Moira, due to said powers. He possesses people and mindrapes them while doing so, has minor reality warping power (which work like a charm on none other than Wolverine and reduce him to a borderline blubbering wreck for a while), and does all kinds of terrible things... because he desperately wants to see the father who left the family shortly after his powers manifested. While this is a far cry from the horror version of the character in the comics, it's a Justified Trope since this particular X-Men cartoon was an animated series geared towards kids and young teens in The '90s; Proteus wouldn't have fitted in the cast, had his portrayal not toned down.
  • The Batman's version of the Cluemaster. He was a former game show contestant and he believes he lost because his opponent cheated. He has spent 30 years doing nothing but plot his revenge. In his mothers basement no less.
  • Brak progressed from a supervillain in Space Ghost to being an annoying loudmouth with a childlike attitude in Space Ghost Coast to Coast, Cartoon Planet, and The Brak Show. It is said that he suffered brain damage after Space Ghost.
  • Quackerjack from Darkwing Duck, going along with his "power" of making deadly toys.
  • Cheryl from Archer combines the D and E types.
    • Archer himself might qualify, being somewhere between C and E. (No, not D.) He views killing people as play and is a whining self-centered brat whose world revolves around his mother.
    Commander Kellogg: Archer broke both of Wu's arms while shouting "woo!"
    Archer: Happy coincidence!
  • The Legend of Korra:
    • Tarrlok has shades of this in episode 8. He has a lot of power in Republic City but comes off as a spoiled brat who will do anything to get what he wants and won't listen when others try to reason with him. However, it's much more complicated
    • Amon/Noatak is ultimately shown to be a this in the finale. He comes across as a naive man who just wanted the good life with his younger brother (who happened to be the aforementioned Tarrlok) that their abusive childhood at the hands of their father, Yakone, denied them.
  • Discord from My Little Pony: Friendship Is Magic is an omnipotent Reality Warper and a Magnificent Bastard, but he's basically an all-powerful Trickster God who views the entire world as his own personal play thing. This includes the ponies, who he gleefully Mind Rapes, breaks, and drives insane. He's well aware of how evil his actions are, but doesn't care so long as he's having fun. He also pretty much Rage Quit when Fluttershy actually won his mind games, brainwashing her via brute force and leaving in a huff.
  • Baron Vain from The Modifyers, the Big Bad who gleefully goes "Yay!" when his favorite agent shows up, to ecstatically feeding incompetent henchmen to a gigantic fish while playing opera music.
  • Darth Maul shows spades of this in his return in season 4 finale of Star Wars: The Clone Wars. He hides himself from Savage behind boxes and can only be lured out by Mother Talzin's bright, floating energy ball, which he chases after in a way you would expect a small child to. Sure, he gets "better", but the effect is still fairly tragic and quite disturbing.
  • Senor Senior Junior is a mild form of this trope. At one point when his father told Kim Possible when rescuing a band from the former's clutches, told her that he'll unveil his new toy: a laser turret. Junior then tells Senior that he told him earlier that the turret was not a toy (implying that Junior attempted to play with it), before Senior explained that he meant the term figuratively.
  • South Park:
    • Satan is whiny, insecure and fickle. He doesn't even seem to be that much of a bad guy, and on his good day his domain can be quite nice a place. But he easily falls under bad influence and will launch an invasion against Heaven or Earth at the drop of a hat.
    • Stan's father Randy Marsh sometimes falls into this category, one such example is from the episode "Night of The Living Homeless" in which he threatens the other townsfolk with a shotgun holding them hostage fearing they could become "one of the homeless" (treated like a zombie plague), he then murders his friend Glen after learning he lost his house, then later acting as if he were still alive.
  • Shredder's mutant henchmen Bebop and Rocksteady from the 1987 1987 Teenage Mutant Ninja Turtles cartoon were shown to read comic books, watch cartoons, and play video games in their spare time. In general, they also did tend to act very childish.
  • Eddy's brother from Ed, Edd 'n' Eddy. He's an adult and he still likes to beat up kids, especially his brother Eddy.
  • Adventure Time: The Ice King has shades of Type B and E, though he's a mostly lighthearted example, mostly harmless despite his habit of kidnapping princesses. Then the story takes a much darker twist when his origins are revealed, and how far he's fallen from the man he once was.
  • Wander over Yonder:
  • Snaptrap in Tuff Puppy who constantly makes evil schemes for petty reasons (like blowing up the sun to make popcorn), acts like a immature dick to his henchmen, and constantly argues with his mom.
  • Humphrey Dumpler, aka Humpty Dumpty, gets given this treatment in Beware the Batman. Whereas his comics incarnation was an Ineffectual Sympathetic Villain, placed in Arkham Asylum because he was genuinely mentally ill even if he was normally non-violent and inoffensive — he finally snapped because of all the abuse his grandmother gave him, murdered her with an axe, then sewed her together with bootlaces to try and "fix" her — the cartoon Dumpty is a child-like man who is driven by revenge, kidnapping people he blames for the brain damage that left him how he is and trying to blow them up in his first episode, then setting up lethal deathtraps in his second episode.
  • Dan Vs.: The titular character has argued over sci-fi memorabilia with Chris, and has no job or girlfriend, let alone a wife.
    • Chris' wife Elise seems to switch between endearment and irritation with Dan. It's gotten to the point where she sometimes treats him as if he were their kid. In "Dan Vs George Washington" she lets him sleep with them (because he couldn't sleep) and proceeds to tell him a bedtime story, much to her husband's disdain.
    Dan "Tell me a story..."
    Elise "There was once a little prince who was so very angry-"
    Dan "Was his name Dan?"
    • In that particular instance, Dan couldn't sleep because he was upset that his plan failed, and he says it in a very childish way, sounding more like a kid with a drawing no one wants to look at than a man on a vengeful rampage.
  • Scoutmaster Lumpus in Camp Lazlo, who confiscates Bean Scout toys so he can play with them himself and often throws tantrums when things don't go his way. Hell, Slinkman once told him to go to his room and think about what he did. Miss Mucus is a Psychopathic Womanchild as her man-hating qualities border on an almost elementary-age manner and she hoards toys as well.
  • Doctor Doofenshmirtz from Phineas and Ferb is a mix of Types C and E. It's shown a number of times that, despite ordinarily seeming like an Ineffectual Sympathetic Villain, he actually could be a serious threat if he really tried-it's just that he's too distracted trying to get petty revenge for old grudges. He also often treats the fight between good and evil as though it's just a game he and his friend/nemesis Perry like to play with him as the bad guy, and gets annoyed by other villains who "cheat" (such as building devices without self-destruct buttons or devising traps that hold their nemeses for longer than the Exposition they're about to give requires), despite himself often breaking those same rules.
  • Uncle Grandpa can be a Type E at his kookiest.
    I do like it when the Earth explodes...
  • Xavier: Renegade Angel is an anti-heroic example; while he always means well, it's clear he's a total lunatic. His basic response to any problem is to walk in with no clue what's going on, poorly act like he knows what he's doing, screw everything up, and then throw a hissy fit if someone suggests he's done something wrong. In the first episode of Season 2, an unnamed bully asks him "Are you going to go crying to your mommy about it?"-and Xavier answers "Yes, I am". His trying to find his mother in order to do so is the basic plot of the second season.
  • Spliced:
    • Entree is a Type E. A good example is in the "jokes" he pulls on Fuzzy in "Sgt. Snuggums" which include, among other things, getting killer bees to attack him and throwing him in a volcano.
    • Peri is a Type A. He's really a very nice guy, but he's just too stupid to avoid getting manipulated into going along with Entree's insane schemes.
  • Creator/Filmation has many a Big Bad who are profoundly childish, egotistical and immature which contrasts with their formidable powers and makes them ironically more kid-friendly:
    • Filmation's Ghostbusters has Prime Evil who despite being an all-powerful sorcerer from another dimension who can summon and materialise the dead from limbo, is also a self-important fool who gets angry at his henchman for having an idea, because only he is allowed to have ideas and wishes revenge for really exaggerated slights like a haunted house attraction which he sees as insulting and statues in honour of the ghostbusters despite the fact that the living have no reason to honour or even like him.
  • Bill Cipher of Gravity Falls comes across as this occasionally, especially in the Grand Finale of the series. His main interest in using his extremely dangerous Reality Warper powers is having his own sick brand of "fun." Bill likes to mock his enemies with childish insults ("It's funny how DUMB you are!"), and, when he pulls a Grand Theft Me on Dipper in one episode, spends his time gleefully drinking soda "LIKE A HUMAN!" and deliberately causing his new body pain. In the last episodes, he even outright tells Ford that he plans to rewrite humanity's universe into the "ultimate party," envisioning himself and his demonic minions goofing off as they conquer space and time. True to form, Bill's psychopathic tendencies come out when he doesn't get his way or has to wait for something; the problem is that his temper tantrums are deadly.

Alternative Title(s): Psychopathic Womanchild, Psychotic Manchild
