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.
