Lisa Trevor

Mo... ther...

Lisa Trevor was a human test subject forced to undergo a plethora of heinous and illegal biological experiments conducted by the nefarious Umbrella Corporation. The side-effects of the experiments have mutated Lisa into a monstrous abomination.

Background
Lisa was born to George and Jessica Trevor around the year 1953. Several years after her birth, Oswell E. Spencer hired George to design a special mansion complex for him high up in the secluded Arklay Mountains, which would also host a secret underground laboratory. Spencer, paranoid that George would someday leak the mansion's secrets to the public, began plotting a suitable fate for him and his family.

Inviting the Trevors to the mansion, George was expectantly forced to arrive several days after his wife and daughter's arrival. During this time, Lisa and Jessica were apprehended by Spencer's men and dragged to the research facility underground, where they were to be experimented on as human test subjects for the Progenitor virus.

When George finally arrived, he was informed by Spencer that the two had left earlier to attend an unwell relative. After finding the right opportunity, George was also apprehended, though managed to escape. He would never find his family, though would soon realise that they were still in the estate - somewhere.

On November 10 1967; some time after George's death from malnutrition, Lisa was administered the "type-B" variation of the virus, while her mother was administered with "type-A". Lisa's body didn't immediately begin to exhibit signs of mutation and absorb the virus. Over a period of time, under observation, both Lisa's mental and physical state were grotesquely altered.

Jessica made preparations to escape and sent a letter to Lisa informing her of it. The two were to pretend to be unconscious from the drugs while their water was changed. Jessica knew that this would be the right moment to run out of the door. However, the letter would never get to her in time.

Umbrella killed Jessica shortly after she was given the virus because she displayed no reaction to the treatment. In order to pacify Lisa, who had been separated from her mother during their imprisonment, Umbrella sent in staffers who had been disguised as Lisa's parents to provide her with a sense of security. However, Lisa was able to recognize them as impostors and violently killed them. Umbrella made repeated attempts to subdue Lisa, but all attempts failed when she ripped off their faces and attaching them to her own body for safe-keeping. The increasingly mentally unstable and lonely Lisa grew obsessed with finding her true mother so that she could "give her back her face". Lisa was able to find the secret tomb of her mother, built under the Spencer estate. While she was able to recognize the scent of her mother, she was unable to open the stone coffin and "reunite" with her.

Even after her mother's death, Lisa continued to serve as a test subject for even more biological experiments. Unlike her fellow, more fortunate test subjects, Lisa was able to survive all of their tests, regardless of the potency of the implanted virus or parasite. This uncanny immunity earned the attention of Umbrella Corporation researchers, Albert Wesker and William Birkin, who injected their formidable guinea pig with a specimen of the NE-α Parasite. To their astonishment, Lisa not only overcame the specimen, but also managed to absorb it and adapt its powers into her system. Ultimately, this was a major breakthrough for the Umbrella Corporation, that would later go on to play a pivotal role in the engineering of the G-virus.

After the G-virus was extracted from Lisa, the Umbrella Corporation lost interest in her. As time passed, Lisa's mutations and loneliness lead her to become increasingly violent. On one occasion, she brutally assaulted and killed three lab researchers. As Lisa was now seen a vestigial threat, Umbrella Corporation officials called for Lisa's destruction. Sometime in 1995, Lisa was supposedly slain in an undisclosed area of Spencer's estate. However, little did the Umbrella Corporation realize, the myriad of experiments conducted on Lisa had left her impervious to almost all forms of physical battery, rendering her immune to all gunfire, to the extent an anti-tank missile had little to no effect on her aside from swatting her against a wall. Even with her death "confirmed" after three days of monitoring her vital signs, she was able to regain her life some time after being dumped in an unknown location. Lisa would go on lurking through the catacombs of Spencer's estate, secretly taking residency under a neglected, dilapidated cabin in the Courtyard.

During the 1998 "Arklay Mountains Incident", various members of Raccoon City's Special Tactics And Rescue Service (S.T.A.R.S.) encountered Lisa while seeking refuge in the estate. After Jill Valentine solved the puzzle of Trevor's crypt, Jessica Trevor's skeleton was finally exposed. Lisa suddenly became emotionally crazed. After a bizarre display of closure, Lisa jumped into the abyss surrounding the altar.

Shortly after his revival, Albert Wesker met Lisa in the Laboratory, next to an elevator. But yet again, due to her regenerative abilities, she managed to awaken shortly after the elevator went up with Wesker in it. Later, at the Main Hall, Wesker met her again. Knowing he had mere minutes left to evacuate before the Mansion's auto-destruct sequence finished its countdown, he counted a fight with Lisa as a "non-priority", and so looked for another way out. After failing to escape her, he resorted to fight her, knocking her out again, and abandoned her. She then managed to find him by heading to the Main Hall. After the final battle, she was crushed by a chandelier while Wesker escaped, and was killed for good when the mansion exploded due to the self destruct sequence set off by Rebecca Chambers.

Appearance
As aforementioned, Lisa’s mutations have hideously deformed her physical build. Lisa’s hideous face is partially masked by collections of flesh from her victims. During some cut scenes, one may be able to notice one of Lisa’s uncanny eyes through a small hole in her mask. In Rebirth 2 it is possible to see her teeth. Her oversized arms and hunchback give her an orangutan-like appearance. She is draped in a tattered hospital gown with her hands held together by a pair of wooden manacles lined with iron, which acts as deterrent to Lisa's attacks. There is also an eyeball-like tumor visible on her back, a typical sign of the G-virus. Lisa can therefore deal considerable amounts of damage to her victims, and should not be confronted directly, as no weapons can truly stop her. Numerous tentacles will emerge from her body and undulate violently when she is attacked, a sign of the NE-α parasite used to create the Nemesis T-Type.

While in various parts of the Spencer Estate, one may hear the harrowing wails and cries of Lisa. This characteristic suggests that Lisa is incapable of using a higher level of thought and therefore conforms to a more animalistic nature. However, it should be noted that Lisa was able to start a fire in order to warm herself, as well as write a few crude entries in her journal. She also is able to croak, "Mo...ther..." upon finding her mother's skull.

Mutation/Abilities
Lisa was administered the "type-B" variation of the Progenitor virus. After that she served as a test subject for even more biological experiments. Lisa was able to survive all of their tests, regardless of the potency of the implanted virus or parasite.She was injected a specimen of the NE-α Parasite in which, to the Umbrella researchers' surprise, Lisa not only overcame the specimen, but also managed to absorb it and adapt its powers into her system.

Lisa main attacks includes pummeling herself towards her enemy and hitting them with her chain and shackles. However, Lisa's true power is immortality, as she is capable of taking huge amounts of damage and still manage to get up after an extremely short regeneration time. There were rumors that she actually became immortal from experiment and even Albert Wesker doubted if she really was while fighting her.

Trivia

 * Lisa did not appear in the original Resident Evil; she was added to the remake in order to provide additional support to the background story of the game, along with providing reference to other games (Resident Evil 2 and Resident Evil 3: Nemesis).
 * Lisa's improvised living space bears a strong resemblance to Larry Drake's hideout in the 2001 film, Dark Asylum. Furthermore, the opening sequence of the movie is very similar to the cut scene where one first hears Lisa in the mansion's main hall.
 * It is interesting to note that the Guardians of Insanity creatures from RE5 Lost in Nightmares chapter bares a striking resemblance to Lisa Trevor. They have similar appearances such as the shackles around the feet, tattered robes and hunchbacks with the G-Virus eye. They could be a reference to Lisa Trevor as well as the other original RE references.
