Dragon Ball: Every Canon Fusion’s Dominant Personality

Although fusions in Dragon Ball are considered their own unique individuals, it's pretty obvious that each fusion in the series takes most of their personality from one character over the other. This was the case for Dragon Ball's first fusion, Gotenks, and holds true all the way up to Dragon Ball Super's fusions like Kefla and Gogeta.

Every fusion in Dragon Ball has a dominant personality that dictates how they behave in battle, even if it doesn't always influence their clothes or abilities. When looked at under scrutiny, Dragon Ball fusions are rarely, if ever, actually equal. One half of the fusion always gets the short end of the stick.

8 The Nameless Namekian: Piccolo

Piccolo is technically the first real fusion in Dragon Ball. Kami and Piccolo used to be the same person, simply referred to as the Nameless Namekian, or Son of Katas. After traveling to Earth, the Son of Katas aspires to become the next God of Earth, but to do so, must expel the evil from his body. This evil goes on to become the Demon King Piccolo, while the good half of the Nameless Namekian becomes Kami. In the Cell Saga, Piccolo and Kami finally refuse into one being who Goku jokingly calls Kamiccolo.

In order to agree to the fusion at all, Piccolo demands that he be the dominant personality, effectively leading to Kami's death. While the new version of Piccolo does retain some minor elements of Kami's personality (fondness for Mr. Popo and the respect of Shenron), he still considers himself a demon in Dragon Ball Super and more or less acts the same, just more mature. Piccolo does the same thing to Nail when he assimilates him on Namek, taking all of Nail's Power Level, but retaining his full personality.

7 Gotenks: Trunks

Gotenks is basically all Trunks, though a lot of this has to do with Goten being an incredibly under-written character in Dragon Ball Z. Both Gotenks and Trunks are extremely mischievous characters, whereas Goten is a bit more mild-mannered. The biggest sign Gotenks takes his personality from Trunks, however, is how he treats Super Buu.

After watching Chichi get killed by Super Buu, Goten becomes incredibly determined to beat Buu, immediately training in the Hyperbolic Time Chamber to Trunks' surprise. That said, none of this personal vendetta extends to Gotenks. Gotenks is all jokes and laughs, and doesn't think twice about wasting time to avenge Chichi, preferring to play around with Buu in Trunks-like fashion.

6 Old Kai: Young Elder Kai

Most of the Potara fusions in Dragon Ball are interesting because they really do not feel like two characters becoming one. The Old Kai is the result of an Old Witch stealing a Potara earring from the East Supreme King of 15 Generations Ago, and accidentally fusing with him.

That said, there's zero indication any of her personality exists in the Old Kai fusion. By all accounts, the Old Kai kept his entire personality, simply becoming uglier upon fusion and inheriting the Old Witch's unique potential unlocking abilities.

5 Kibito Kai: Supreme Kai

Without knowing that using the Potara earrings results in a permanent fusion (for Kais, at least), the Supreme Kai Shin and Kibito fuse into Kibito Kai during the Majin Buu arc to show Goku that he has an option to beat Super Buu. Like the Old Kai, Kibito Kai seems to effectively erase the personality of the less dominant fusee. Kibito Kai is more or less the Supreme Kai with Kibito's abilities and color scheme.

In Dragon Ball Super, Kibito Kai uses the Dragon Balls to defuse back into the Supreme Kai and Kibitio, while Dragon Ball DAIMA has them trigger the mysterious gas inside Majin Buu to disconnect them. Either way, this does imply fusions can tell when their participants would rather not remain fused – which is a little horrifying, honestly.

4 Vegito: Goku

The idea that Vegito is a Vegeta dominant fusion and that Gogeta is a Goku dominant fusion is one of the biggest misconceptions in Dragon Ball, likely stemming from the poor translation of Vegito's name. Vegito is a misspelling of Vegetto, which is a combination of Vegeta and the Japanese Kakaratto. The English Dragon Ball manga ends up renaming Vegito into Vegerot to match the Vegeta + Kakarot connection.

Either way, Vegito shows more signs of Goku's personality than Vegeta's. Vegito is playful and a tactical genius more in line with how Goku fights, but most importantly, Vegito looks just like Goku in the original Dragon Ball manga. Akira Toriyama draws Vegito with the same eyes and face shape as Goku. He even wears Goku's gi with a flipped color scheme, the only clothing he inherits from Vegeta being his gloves and boots.

3 Fused Zamasu: Zamasu

Fused Zamasu is one of the most interesting fusions, since he's the combination of the same exact characters in two different bodies. Zamasu and Goku Black use the Potara earrings to become Fused Zamasu, who retains most of Goku Black's design, albeit tweaked to match Zamasu's Supreme Kai physiology.

Personality-wise, Fused Zamasu very much feels regular Zamasu leading the charge, but it's a bit harder to tell since Zamasu and Goku Black are ostensibly the same person. That said, Zamasu is depicted as being more in control regarding their relationship, so it stands to reason he'd be the more dominant personality over Goku Black. The constant crying and monologuing seems to suggest this, as well.

2 Kefla: Caulifla

Aside from her clothes and Power Level, which come directly from Kale, Kefla is basically just Caulifla in a new coat of paint. Kefla has all of Caulifla's confidence and spunk as part of her personality, and none of Kale's more reserved, demure attitude. This makes sense on a writing-level, since a timid fusion fighting against Ultra Instinct Goku or Ultimate Gohan (in the manga) isn't exactly narratively compelling.

In the Dragon Ball Super anime, Kefla and Goku's dynamic is more or less an extension of Goku and Caulifla's relationship, now flipped into a full-blown rivalry since Kefla has the power to fight against Goku evenly, unlike Caulifla. Kefla is yet another example of a Potara fusion having a clearly dominant personality to the point where one half of the fusion might as well have experienced an ego death.

1 Gogeta: Goku

Like Vegito, Gogeta is way more Goku than Vegeta – though a bit more even considering Gogeta was perfectly comfortable killing Broly at the end of their fight, something Goku realistically would not be okay with. Other than that, however, Gogeta looks like Goku, acts like Goku, and primarily uses Goku's moves.

This makes sense on every level: Goku is Dragon Ball's main character, so it stands to reason any fusions featuring Goku would go out of their way to keep Goku the dominant personality. This does mean Vegeta has no dominant fusions in the series, since both Vegito and Gogeta take most, if not all, of their personality cues from Goku.
