Chica, like her friends, attacks only because she is possessed by a dead and vengeful child that wants to avenge herself and her friends by killing their killer. However, she doesn't know how their killer looks like, only that they're a night guard (heavily implied by the SAVE THEM minigame). Because of this, she attacks any night guard, hoping that one day, she'll find the one person. She was lured and killed by Afton claiming that her dog isn't dead.
