Ellen Ripley
20th Century Fox initially conceived "Alien Resurrection" as centered around a teenage clone of Newt, inspired by Buffy Summers in "Buffy the Vampire Slayer". However, the studio reconsidered abandoning the emphasis on heroine Ellen Ripley and told screenwriter Joss Whedon to make the story about a clone of Ripley instead. Although Sigourney Weaver favored Ripley's death at the end of "Alien 3" in the hope that it would deter rumored "Alien vs. Predator" films, she supported Whedon's concept of a human-Alien hybrid because of the character's uncertain loyalty to either half of her genealogy.
