Lisa Trevor (リサ・トレヴァー,Risa Torevā?) (c.1953-1998) was an American superhuman, and the first person to become a Progenitor adapter since at least the Neolithic. Trevor was abducted as part of a retroviral research project by what would later become Umbrella Pharmaceuticals. Having survived and mutated from exposure to a Progenitor strain, Trevor's enhanced abilities made her a regular and reliable test-subject in bioweapons research. Trevor's usefulness to the company ended in 1988 after twenty years of testing, when a Progenitor strain dubbed Golgotha Virus was isolated in her blood. Trevor's abilities allowed to her to survive her planned execution, and she would go on to live in the mountains until 1998 when she involved herself in the Mansion Incident, ultimately dying when the facility was destroyed.[excerpt 1][excerpt 2]
Lisa Trevor was born around 1953 to architect George Trevor and his wife, Jessica. Trevor & Chamberlain was at the time a well known construction firm which specialized in eccentric and elaborate building designs. From 1964-1967 the company built the elaborate Spencer Mansion in the Arklay Mountains, with Trevor herself being immortalized in its design as a wall painting in its gallery. Upon the mansion's completion, the family was invited over to as guests of the client, Dr. Oswell E. Spencer, Earl Spencer. With George himself caught up with work, Jessica drove on to the mansion with Lisa where they planned to stay over the week until George arrived.
Arriving at the mansion around Friday 10 November, the two were immediately detained by Spencer's security guards and taken into an underground cavern. There, they were injected with the 'Type-A' and 'Type-B' strains of Progenitor Virus, a newly-discovered retrovirus Spencer believed would be useful for eugenics but which required alteration to successfully mutate a human. Over the next few days, both were subjected to further testing while their mental state deteriorated, likely the onset of brain-damage as an effect of the Progenitor disease. While Jessica made plans for a break-out on Monday 13 November, her immediate execution prevented any hope of Lisa escaping. Unlike her mother, however, Lisa's body reacted much better to the Progenitor infection and she developed a degree of superhuman strength, though not to the extent a properly engineered Progenitor strain would have accomplished. On Wednesday 15 November, Lisa's deterioration continued in spite of her enhanced abilities, and she went into a violent outburst during dinner with a Spencer employee impersonating Jessica. When Lisa realized the deception, she believed the woman had stolen Jessica's face, and attempted to cut it off and give it back to her mother. It is uncertain if the woman died from these lacerations. Over the next several days Lisa's mental state worsened further, with her diary suggesting she had briefly escaped the lab following the attack. Her claims of having found the graves of both her parents cannot be reconciled with known events, however, as George was at the time still alive.
Over the next twenty-eight years, Trevor remained beneath the estate, and was moved into the Arklay Laboratory upon its completion. Trevor's existence was kept a company secret, with none of the researchers at the facility knowing her name, and few knowing she existed at all. Over this period Trevor continued to deteriorate, falling into a stupor, though kept chained to her bed in the event she recovered. For much of the first twenty years she was fed through intravenous therapy, and transported by wheelchair if she needed to be moved. From 1978, Dr. William Birkin, the facility's new chief researcher, made considerable use of her abilities as the need for test subjects increased. In 1988, Trevor was selected to be the host of a NE-α Type parasite. These parasites had been engineered by Umbrella Europe to replace the brain functions in a B.O.W. to improve performance, but had a low success rate. During the surgical implantation, Trevor's immune system attacked the organism and destroyed it, absorbing its DNA into her own. Not only was her consciousness restored with a degree of intelligence, but she grew tentacles on her back. When searching for an explanation, Birkin isolated a Progenitor mutant strain entirely distinct from the t-Virus she had previously been tested with.
Over the next seven years, Trevor became a hindrance to research; with her mind restored, she was once more able to use her enhanced strength in her obsessive need to collect faces, making her a danger to all women especially. Following the deaths of three researchers in 1995, the executives had had enough, and orders were given for the Umbrella Security Service to execute her. Owing to her regenerative abilities, the U.S.S. waited three days before declaring her deceased, and her body was taken away for disposal. Disposal was handled by Birkin's successor, Dr. John Clemens, a researcher the Intelligence Division considered a potential security risk owing to his views on research ethics.
Where Trevor was taken is uncertain, but she made her life in the Arklays as a mountain woman surviving on her own means. Following the t-Virus outbreak at the Arklay Laboratory in May 1998, Trevor's territory expanded or moved to encompass the estate and land to the east, making a home out of a shed the staff used to store pumpkins and other vegetables grown nearby. Based on the findings of the Raccoon Police Department's Special Tactics and Rescue Service who stayed at the facility from Thursday 23-Saturday 25 July, Trevor had made use of the underground tunnels she was first infected in, accessed from a trap door in the shed. In one room were a number of objects she had stolen from the mansion. Trevor made repeated threats on S.T.A.R.S., and at one point fell into a chasm when she found her mother's corpse. On the Saturday morning, Trevor had made her way out of the chasm just as the facility's self-destruct system was activated. Exploring the lab regardless of the situation, Trevor encountered Dr. Albert Wesker, one of her torturers who had since become a S.T.A.R.S. Captain. Wesker by this point had also become a superhuman thanks to exposure to a t-Virus strain with more typical Progenitor properties, and was able to escape her. Following him into the mansion, Trevor continued to harass him, eating up more and more time. During her fight with Wesker in the entrance hall, Trevor was pinned down by a falling chandelier, allowing Wesker to escape as the mansion exploded.
↑Excerpt from Art of Arts, p.52: "アークレイ研究所で進められ、後の大規模な生物災害の引き金にもなった「t-ウィルス計画」。その裏には、ある一家の悲劇が隠されている。アークレイ山中に建設されたアークレイ研究所は、地上の西洋建築によって巧妙に偽装された極秘研究施設で、洋館内には侵入者の脱出を遮るさまざまな仕掛けが施されている。この建物を設計したのが、有能な建築家ジョージ・トレヴァーである。彼は、オズウェル・E・スペンサー卿からの依頼で5年の歳月をかけて洋館を建築したが、 竣工後にお礼と称して洋館に招待され、結果的にそのまま幽閉された。スペンサーの目的。それは、まさに彼の口封じ。洋館の隅々まで知り尽くしている人間をスペンサーが自由にするはずはなく、ジョージは家族ともどもt-ウィルス計画の生体サンプルにされるという哀れな運命をたどることになる。 最初に実験材料となったのは、ジョージの妻であるジェシカと娘のリサだった。ジェシカには始祖ウィルス変異体のTYPE-A、リサにはTYPE-Bが投与されたが、ウィルスの定着化に失敗したジェシカは非情にも廃棄処分にされた。一方、リサの方はウィルスの定着化が認められたために厳重な観察下に置かれ、以後約30年もの間、生体サンプルとして利用されることになる。残されたジョージについては、彼が綴った「トレヴァーの手記」からもわかる通り、一度は洋館からの脱出を試みている。しかし、スペンサーが新たに設置した仕掛けによって行く手を阻まれた彼は、最終的に妻と同じように始祖ウィルス変異体を投与され、実験失敗後に廃棄処分となった。 ウィリアム・バーキン主任研究員の下で進められたウイルス研究では、試作ウィルスを開発してはリサに投与するという実験が繰り返された。ウィルス投与によって自我を失い、徐々に異形へと姿を変えていくリサ。 しかし、20年以上が経過してもなかなか成果が現れないために、リサはいつしか研究員たちから「デキソコナイ」と呼ばれるようになっていた。リサが再び有益な研究対象として注目されたのは、バーキンが彼女の体に寄生生物「NE-α型」の原型を移植したころである。リサの体内で新たなウィルス「G」の原型が発見されたことで、バーキンはすぐさまt-ウィルスを超える「G-ウィルス」の開発計画を発案。一方、リサはネメシスを取り込んだことでわずかながら知性を取り戻し、奇径な行動を取るようになる。母親の面影を追い求めるあまり、女性研究員を襲っては顔面の皮をはぎ取るリサに対して、アークレイ研究所が出した結論は「廃棄処分」だった。研究が新たな段階に入った以上、彼女を生かす理由がどこにもなかったのだ。 リサの最終処理は念入りに進められた。その理由は、 彼女が長年のウィルス投与実験によって驚異的な生命力を身に付けていたからにほかならなし、しかし、3日間にわたって生命反応停止が確認されたにもかかわらず、リサは死んではいなかった。処分後もアークレイ山中の闇の中をさまよい続け、3年後には洋館事件の調査で山を訪れたS.T.A.R.S.の前に出現。最終処理前と変わらぬ怪力で隊員の命を奪おうとする。"
