The theory presented combines all previous theories about the Five Nights at Freddy's (FNAF) series. It explains that the main killer is not the Purple Guy, but rather the Pink Guy, who is actually an animatronic controlled by the spirit of a child, specifically the daughter of the Purple Guy. The Purple Guy, who is the father of the children, is a protective and caring character who lost his children to the animatronics created by Henry. The Purple Guy's goal is to dismantle the animatronics, but he ends up being killed by the Springtrap animatronic. The theory also explains the connection between the different games in the series and the events that led to the Purple Guy's demise.
