Formed by Spencer, with two intellectual confidants, Edward Ashford, and James Marcus, Umbrella grew to become more than just a pharmaceutical company. Through its investment, and political power, it quickly took hold, and enveloped the Midwestern town of Raccoon City, spreading it shadowy influence over the inhabitants, like a virus. Covertly, Umbrella employees conducted illegal viral experimentation, with plants, and animals; their goal, as instructed by Spencer, the creation of deadly bio-weapons. Lisa Trevor, more than any other individual, provided Spencer, and Umbrella with their most influential, and successful asset. Her body became a living canvass to a spectrum of viruses, cast upon her during the most heinous experimentation, in pursuit of one goal. Bio-weapon development.

I feel dizzy after that shot they gave me. I don't see Mom. Where did they take her? She promised that we would escape together. Did she escape alone and leave me behind ?

The tragedy of Lisa Trevor can be traced back to a treacherous night in 1967, November 10th. It was on this fateful night that Spencer instructed his men to kidnap both Lisa, and her mother, Jessica, from their respective rooms, as her father, George, remained delayed with business. On his arrival, at the mansion, his families disappearance will be covered up by the devious Spencer, as George too, falls foul to Umbrella’s insidious activities.

Lisa’s first, and seemingly safe encounters, whilst at Spencer’s invitation, are chronicled in the files to be found in BIO HAZARD 15 minute demo, and George Trevor’s Notes, published in The True Story Behind Biohazard. Lisa & Jessica Trevor’s fate were sealed upon their arrival at the Spencer mansion, irrespective of George’s late arrival. They initially enjoy Spencer’s grand hospitality. Lisa entertains her mother, and Spencer by playing Beethoven’s Moonlight Sonata, on the newly delivered grand piano, in the smoking lounge. However, later that night both mother & daughter are incarcerated within the mansion’s underground research facility, and immediately become victim to the scientists evil, viral experiments.

Five days from their initial incarceration, and daughter has murdered mother, in confused, violent frenzy. Notwithstanding Lisa’s likelihood for mistaken identity, this female not being Jessica, she has certainly committed her first kill, with a horrific characteristic. This savage, signature assault would come to illustrate Lisa’s increasing mental instability, generated by forceful removal from her mother, and institutionalised isolation, coupled with the devastation caused to her cognitive abilities, at the hands of Spencer’s new virus. From this day onwards, and for years to come, Lisa will mournfully carry the hideously detached faces, of those whom she seek to be her mother, with determination, and devotion for their reunion. Her mind now catastrophically destroyed, as Progenitor wreaks its havoc, she becomes pitifully enslaved to the delusion of returning her mothers detached facial flesh to an alive & well Jessica. Here lies the origin of this psychologically motivated assault, that was to become a characteristic attack. It stems from Lisa’s reaction to the grim discovery that her mother’s mind has been lost to Spencer’s viral experimentation. From the initial elation that she has at last found her beloved mother, to the grave, and deep devastation upon the discovery that Jessica’s mind had been destroyed to an unrecognisable extent.

As a consequence of Lisa’s diminishing intellect, the possibility exists that this tragic victim was not Jessica; Lisa’s first kill being in fact a case of mistaken identity. Jessica’s unfamiliarity {‘But she was a fake..same face but different inside’} a symptom of the havoc wrought by Progenitor, confusing the mind of her daughter to the extent that Lisa mistook a female scientist as her mother, rather than mental retardation within the true mother being the cause of the anomaly that Lisa perceives. Those unfortunate Umbrella staff, charged with the grim task of conducting research on this lab rat, would fall victim to this savage assault, birthed in fury upon Lisa’s realisation that she has wrongly presumed these woman to be her devoted mother.

Just one week after Spencer's betrayal, it's November 17th 1967, and Lisa Trevor finds a crypt, deep below the mansion her father designed, housing her mother's tomb. Despite her inability to remove the stone lid of the coffin, she can recognise Jessica's scent, but any realisation of her mother's demise is clouded by further cognitive deterioration ~

from inside box, scent of mommy. maybe true mother there. stone box hard. It hurt. steel rope in the way. can't see mother becuz 4 stones.

While Lisa was able to recognize the scent of her biological mother, she was unable to open the stone coffin and finally reunite with her. Despite continued failure in her mournful search, Lisa Trevor has already become terminally obsessed with finding her true mother. To merely, finally see her mother, is the only element Lisa craves for this reunion. She will return to this scene, and her wish will be granted, but not in the manner that she would have desperately desired, during all those years of isolation, and loneliness. Shortly after the t-virus outbreak, initiated by James Marcus, in the autumn of 1998, some considerable 30 years after this first discovery, Lisa will revisit the tomb housing her mother's corpse.

November 19th 1967, and it would seem that Lisa’s virus ravaged brain is in the throws of a total mental breakdown ~

daddy atached first, momm atached scond, iNside reD and sLimy, whiTe and haRd, not true moM wheRe, dunno dadd, found mum again, whne atachd mommy, she move no more, she screaming, why?, Jst want to b with her, mom, where, I mis yuo.

Now two days from the grim discovery of her mother’s crypt, the short lived elation felt from a potential reunion with her parents, would have been refreshing, if not limited release from Lisa’s hellish nightmare. But this was to be no happy family reunion. Lisa has already killed her mother in confused anguish, so the ‘mother’ she identifies in this journal entry cannot be Jessica. We know that the ‘dad’ referred to here, who also falls victim to her now characteristic, fatal assault cannot be George, for we have diary entries in his journal with dates proceeding November 19th. These victims, now adding 2 further trophies to Lisa’s grim, and growing collection cannot be her parents. Lisa harrowing attempts to identify the murdered couple with a personal autopsy. Again she is left disappointed and lost, unable to identify her parents scent amongst the victims intestines. The true identities of these poor souls, faces viciously torn off whilst alive, and now adorning Lisa’s grotesquely mutating body, belong to Spencer’s researchers. In order to pacify the uncontrollable Lisa, her behaviour increasingly unpredictable as Progenitor wreaks havoc within her body, a male & female researcher, may have been disguised as her parents, for appeasing interaction. This technique would be but a vain, counter-productive attempt to provide any sense of security, or to illicit calm behaviour, because her face-ripping, signature attack, perversely represents a deep desire to be reunited with her parents, rather than a violent rejection of Spencer’s mimics. To resemble George or Jessica Trevor, in the presence of their daughter, mind now ravished by Progenitor, would have been a known folly, of life threatening proportion. It is far more likely that victims two, and three, faces sliced, and serving as gory ornaments, now adorning their assailant, do belong to said research team, but were murdered as a consequence of Lisa’s cognitive crippling condition, as they conduct their mandatory observations of her, and not due to a purposeful ruse to impersonate her parents. To serve in Spencer’s employment is a dangerous profession, and there will be further casualties amongst the staff assigned to this tragic experiment. They too will fall victim to this horrendous fate, assisting Lisa with her gory collection.

The deterioration in both handwriting & language, is caused by her cognitive deterioration, at the hands of the invading viral onslaught, now into its fourteenth day. And that is all we know of Lisa’s early life within the Spencer mansion, as authored by her own hand. But what of her continued existence. For details of this prolonged, torturous life, in the years prevailing 1967, one must consult the second report of Umbrella employee, Albert Wesker ~ 

Lisa Trevor is referred to as ‘the woman’ by Umbrella scientist, Albert Wesker in Wesker's Report II. It has been just over a decade since Lisa’s initial incarceration, and in the summer of 1978, an 18 yr old Wesker casts his eyes over the estate that houses the Arklay facility, from his vantage point on the helicopter, high above. Together with young, brilliant scientist William Birkin, both men felt the trepidation that comes with the employment of Oswald E.Spencer, as their aerial ride came to an abrupt halt, on the helipad of that infamous mansion. 

Wesker’s Report II then begins an account of the two men’s early experiences in the Arklay facility, working with mutated viruses, in the development of biological weaponry. One such research program included the t-virus project; and one such test subject was to be the guinea pig for this program... Lisa Trevor.

Right from the first night of her capture, and mercilessly continuing on through the next decade, Lisa was experimented upon, like a lab rat, by Umbrella's scientists in the Spencer Estate Arklay Laboratory. Spencer’s scientists, including Birkin, exposed Lisa to many viruses, including the Ebola Virus and the Progenitor Virus. Miraculously, she managed to survive this viral onslaught, when the same such experiments had killed all the other human specimens captured by Umbrella. However, whilst her physical form battled on, twisted, and mutated by the invading poisons, her mental capacity suffered greatly. Such was the extent of her cognitive degeneration, that she no longer recognised her own mother. She became unpredictably violent, attacking a female scientist, she mis-identifies as Jessica. Eventually, after extensive testing, with her dangerous nature outweighing any further positive value, she was deemed useless by Umbrella, and left to rot in her cell, far from the minds of those scientists, who forgot her pitiful existence.

Wesker spent not time in maneuvering for his own specimen, and despite early protestation from Birkin, sought to have this new 'Nemesis Prototype’ the focus for their continued research. With Spencer’s influential hand, the two ambitious men obtained their specimen, a wholly different, and superiorly evolved design to what they had previously worked with. The Nemesis specimen was a parasitic living body, birthed from genetic mutation. Umbrella’s French division’s research had provided evidence that this parasite had an intellect. As a single organism it could not act alone; however, introduce it into the brain of a host, and it would gain control of that animal, and significantly demonstrate a highly developed ability for combat. But as with all of Umbrella’s endeavours, the relative success of this program was restricted by high death rates. When the Nemesis parasite infested itself into a test-subject’s brain, after a mere 5 minutes that subject would expire. Wesker & Birkin sought to increase a carrier’s survival period once the parasite had gained control of its host. Wesker’s eyes inevitably fell upon Lisa Trevor...

In the summer of 1995 Albert Wesker chronicles in detail the development of the G-virus program, which commenced in 1991, and which he had chosen to abandon, pursuing his own path. He has not seen his previous colleague for over 4 years, since William Birkin had re-located to a new facility for testing the G-Virus, covertly located underneath Raccoon City. Through his research into the characteristics of the G-virus, Birkin discovered unique abilities within the surviving body of Lisa Trevor. The program’s initial results showed the G-virus to have a significantly unique quality not seen with the t-virus. Organisms that were infected with G continued to mutate independently. Normally, in order to mutate a virus that has been administered to another body, and external element would have to be added, such as radiation. Uniquely with G, any organism that were to be infected with this virus, would keep mutating itself without the requirement of an external influence. However, unlike its inferior predecessor, t-virus, the G-virus lacked predictability of result. Infected organisms would mutate with any combination of change, and intervention by the researches was fruitless, in attempting to halt such mutation. Initially after administering the Nemesis parasite to Lisa, no immediate physical change was recorded. Yet, internally her gene structure mutated with verve, her continued survival made good by her constant ability to merge, and co-exist with all the numerous viruses she had been exposed to over the past 21 years. This prolonged period of exposure to such viruses had caused her internal system to evolve an ability to accept this parasitic organism. It is this consumption of the parasite that sets Lisa apart from all other B.O.W.s that were consequently infected with the G virus, and grants her an immortality that exceeds all other G infectants, including the Nemesis Tyrant, William Birkin G monster, and Curtis Miller G monster.

The Trevor family tragedy; The deaths of two loving parents, and up until her final release from Umbrella’s servitude, upon the mansions explosive destruction, a daughter too. The demise of a treasured wife, Jessica, is evidenced by Lisa’s discovery of her mother’s skeletal remains, and consequent body identification, corroborated in harrowing detail by her wailing, mournful scream “mother". Her fate, and arguably, that of George Trevor too, is most clearly, and poignantly detailed in the following file ~

Lisa Trevor may have perished in the flames of the Spencer Mansion, but her legacy lived on, as she may have been the inspiration for the development of one of Umbrella's most successful B.O.W.s. The major obstacle that made the mass production of the B.O.W Tyrant using the t-virus, extremely impractical, was that only 1 in 100 million people are able to mutate successfully into a Tyrant. Furthermore, the failings recorded in Umbrella's B.O.W.s in the aftermath of the Mansion Incident, highlighted low intelligence, leading to a behavioral unpredictability that would prove commercially fatal. Consequently, using the t-virus as a catalyst for the creation of Tyrants was considered a failure. The rarity of a perfect specimen Tyrant, when compared to the relative death rates involved, and the behavioral unpredictability of these rarely successful B.O.W.s , lead Umbrella scientists to look elsewhere for a new virus base, or a system for controlling the t based B.O.W.s. Such was the thought process that, in 1998, saw Umbrella combine their mass produced Tyrant B.O.W. with a parasite, developed over a decade earlier. Having recorded the beneficial mutations that lead to Lisa Trevor's increased mobility, and intelligence, after she was able to survive the injection of NE-alpha, Umbrella scientists would hope for a similar reaction within their uncontrollable, low-intellect Tyrant. Their goal in turning to this previously developed parasitic organism, was to establish a control system to combat the previous failings, whilst enhancing both intelligence, and combat ability. This parasite would effectively possess the B.O.W. , transferring its superior abilities onto the host. An increased intellect would hopefully easier facilitate the successful giving of orders. And significantly, with their Tyrant, Umbrella would hope to see a similar ability to survive this administering of the parasite, that marked Lisa out from the usual five minute survival rates. Like Lisa before, the Tyrant was able to survive the NE-alpha invasion, and the resulting B.O.W. would be the Nemesis T type; the legacy of Lisa Trevor.
