Lisa Trevor is a character and enemy in the remake of Resident Evil and Resident Evil: The Umbrella Chronicles.
Lisa Trevor is the daughter of George Trevor, the architect behind Ozwell Spencer's Arklay Mansion and the Queen Zenobia cruiser, and his wife Jessica. Following the completion of the mansion's construction, Spencer invites the family to stay there, but betrays George by kidnapping Jessica and Lisa and uses them as human test subjects for genetic experimentation.
George is also forced to try to escape the mansion, eventually getting lost and dying of malnutrition. Lisa undergoes a series of painful experiments, including receiving the Progenitor virus, while her mother is secretly murdered. Lisa emerges with a grotesque and twisted physical appearance, but gains enhanced strength and nigh-invincibility. Further experimentation on Lisa allows Umbrella's top scientists, Dr. William Birkin and Albert Wesker, to develop the G-Virus. Lisa is then executed and buried, but she survives and hides in the Arklay forest.
She encounters STARS operatives during the events of Resident Evil before ultimately finding her mother's corpse, granting her some closure. Lisa makes her final appearance in The Umbrella Chronicles, where she is defeated by Wesker and left to die as the Arklay mansion and research facility self-destruct.
