He was a sadistic child murderer before the spirits of his victims manipulated him into jumping into the Springtrap suit, as he died inside when he thought he was protected in there. After 30 years, his spirit began to possess the suit and began terrorizing the night guard of the Fazbear's Fright building. The murderer known as Purple Guy (AKA William Afton) has been terrorizing the Freddy Fazbear's pizzeria for many years. Before he went on a killing spree, however, he was a worker at the pizzeria and one of the CEOs. He began killing children around the restaurant, police quickly catching up to the murderer. However, William Afton, being the intelligent criminal that he is, has tricked the police and avoided being arrested. But it wasn't the end. The soul of the children he killed have possessed the animatronics of Freddy, Bonnie, Chica and Foxy. William realized it and decided to destroy the robots. What he didn't predict, though, is the souls of the victims escaping the robots and coming after the murderer himself. In a desperate attempt to survive, Afton equipped the damaged Springbonnie suit. He laughed, assured of his safety, before the suit's spring locks crushed him to death inside of the suit. The children left, believing they were avenged. As William’s corpse rotted inside of the suit, he was discovered after three decades, when the creators of the future Fazbear's Fright attraction searched for equipment. The building was supposed to scare visitors, using the "legend" of the haunted animatronics. However, the suit soon came to be possessed by Purple Guy's spirit, who then resumed his murderous rampage under the name Springtrap, this time targeting a helpless security guard.
