William Afton (voiced by P. J. Heywood in Sister Location, Pizzeria Simulator, Ultimate Custom Night, and Special Delivery) is the series' central character and main antagonist. The founder of Afton Robotics, LLC, he is responsible for the creation of the Funtime Animatronics, and one of the co-founders of Fazbear Entertainment, Inc. Afton was first introduced in the minigames of Five Nights at Freddy's 2, depicted as an unnamed purple figure identified colloquially as the "Purple Guy". These minigames, as well as those from later installments, establish Afton as a child murderer, who killed at least six children (Gabriel, Jeremy, Susie, Fritz, Cassidy, and Charlotte Emily) before the events of the series; these children's spirits would go on to haunt some of the animatronic characters of the franchise, including Freddy Fazbear, Bonnie, Chica, Foxy, Golden Freddy, and the Puppet. Afton himself was killed due to mechanical malfunctions of the Spring Bonnie suit he had worn during the murders and has appeared post-mortem as various incarnations throughout the series; most notably as Springtrap in Five Nights at Freddy's 3, Scraptrap in Pizzeria Simulator, and Burntrap in Security Breach. He has also been speculated to be the protagonist of Ultimate Custom Night, where he endures torment in either hell or his nightmares at the hands of the vengeful Cassidy, who refuses to let Afton die. A character known as Glitchtrap, or "the Anomaly", appears as the main antagonist of Five Nights at Freddy's: Help Wanted, and it has been debated among fans whether he is the real Afton or a digital copy of his consciousness.
