List of Alien (franchise) characters
Alien, a science-fiction action horror franchise, tells the story of humanity's ongoing encounters with Aliens (xenomorphs): a hostile, endoparasitoid, extraterrestrial species. Set between the 21st and 24th centuries over several generations, the film series revolves around a character ensemble's struggle for survival against the Aliens and against the greedy, unscrupulous megacorporation Weyland-Yutani.
The original series consists of four films, Alien (1979), Aliens (1986), Alien 3 (1992) and Alien Resurrection (1997), and revolves around Ellen Ripley's fight against the xenomorphs (aliens) as well as that of her clone. Ripley is the sole survivor of a xenomorph rampage on the space freighter Nostromo, which leads her to a series of conflicts with the species and Weyland-Yutani. Ripley's struggle is the plot of the original series.
The prequel series, Prometheus (2012) and Alien: Covenant (2017), depicts humanity's genesis at the hands of an ancient extraterrestrial race known as the Engineers and the indirect creators of the xenomorphs. A deadly mutagen developed by the Engineers is discovered, which is weaponized by the android David 8, to recreate and perfect the previously long-extinct xenomorph strain. The evolution of the xenomorphs is the main plot of the prequel series.
Several novel series also continue the storylines of characters from the film series, including Alien: Out of the Shadows (2014), Aliens: Vasquez (2019), and Aliens: Bishop (2023). The video game Alien: Isolation (2014), the film Alien: Romulus (2024), and the television series Alien: Earth (2025) explore stand-alone storylines.
