Portal Fanfiction
Valve's puzzle classic pits silent test subject Chell against GLaDOS, the passive-aggressive AI running the abandoned Aperture Science facility. For a two-game series with three characters, its fanfic legacy is remarkable: human-GLaDOS AUs, post-Portal-2 Chell-on-the-surface stories, and the long-running fandom tradition of redeeming or re-villaining Wheatley. Writers love the toxic intimacy of tester and AI, Caroline's buried humanity, and Aperture's pitch-black corporate comedy.

ChellDOS
Chell/GLaDOS
Portal's mute test subject and the passive-aggressive AI who tries to kill her share one of gaming's strangest intimacies: GLaDOS simply cannot stop thinking about Chell, even after firing her into the wilderness with a turret serenade. Portal 2 deepens it with the Caroline reveal and a grudging cooperative arc. The fandom reads obsession, respect, and loneliness into every taunt.

Chelley
Wheatley/Chell
Portal 2's bumbling personality core escapes Aperture with a mute test subject, betrays her atop a throne of power, and ends the game stranded in space rehearsing an apology. 'Chelley' fic mostly writes the human-Wheatley redemption he never gets.
