William then renamed himself to "Fritz Smith" and got a job at Freddy's, He was a suited performer and a security guard. One day, He lured 5 children into the saferoom using the Freddy Fazbear suit, He then got out of the suit and killed all the 5 children. This caused rumours about "The Purple Man" to start, Describing him as a tall purple man with glowing eyes lurking in the pizzeria and killing children. Some stories said that he enjoyed it, Others claimed this was the company trying to cover up fatal malfunctions from the animatronics. He then, as a security guard recorded some tapes as a reminder for himself for his plans. He then went to meet his childhood friend, Sammy Cutz and told him about his plans. One day Freddy Fazbear's Pizza was shut down and he went back to the said place to dismantle the animatronics, However when he did. He avoke the ghosts of the 5 children he murdered. He then hid inside the Springbonnie suit thinking the children will not recognize him but they will instead think he is Springbonnie, He then stood up. The trick had worked at first but the raindrops leaking from the ceiling dripped on the suit causing the springlocks to malfunction and kill William/Fritz inside. He fell down and started to bleed out and twitch violently, The children then disappeared. Leaving him to rot. After 30 years. Afton woke up inside the suit, He saw that he was not himself anymore. He was a rotten green animatronic rabbit with his corpse inside it. He then realised he was not in Freddy Fazbear's Pizza, but another place that had green lighting all around it. He got out of the room he was in and then he saw hanging costumes of the old animatronics that he dismantled. He then renamed himself to "Springtrap"
