William Afton also known as the Purple Guy and Springtrap, was the co-founder of Fazbear Entertainment, and is the main antagonist of the Five Nights at Freddy's franchise. He was a serial killer who targeted infants and young children, and who was directly responsible for all of the incidents and tragedies throughout the series. His role in the franchise's story is pivotal. His story is told via arcade styled minigames, in which he looms in the shadows, appearing as a purple figure.
He was a wealthy businessman and inventor who secretly built animatronics to hunt and kill young children, which went unknown by his partner, Henry Emily. His daughter, Elizabeth Afton, would be killed by one of the animatronics he built. Prior to this incident, his youngest son had unfortunately suffered the same fate. Due to his own selfish reasons, he becomes a serial killer, dubbed The Purple Guy.
He would dress up in a Yellow Rabbit Springlock Suit to trick several young children into following him during birthday parties. Once he had them far enough from their parents, he would mutilate and murder them, before stuffing their corpses into animatronic suits. He was apparently charged sometime before 1993, and tried for the murders of these children, but was released due to lack of evidence. He can be seen during several hidden mini games, such as Savethem.
He eventually meets his end when the souls of the murdered children become so bloodthirsty for revenge that they chase him into a sealed off room. Once inside, Afton tried to scare away the children by wearing the same Springlock Suit that he used to murder the children in. Afton was unaware that the suit was long past its use, and it was extremely damaged and risky to wear. Once inside the suit, Afton laughs at the souls of the children, believing that they will be fooled by the costume's friendly face. However, a droplet of water from the leaky roof lands on the mechanical gears of the suit, and due to the suit's age, they break loose, causing the inner parts of the suit to snap together whilst Afton was in the middle of them. While Afton was slowly bleeding out, the souls of his young victims fade away, leaving him to die alone in the empty room. Eventually, William succumbs to his injuries due to his entire body being crushed. His corpse is then essentially 'locked' inside the suit, forever.
With their killer suffering a horrific and brutal fate, the children are presumably able to peacefully pass away., a
