William Afton, also known as the Purple Guy among other names, is the main antagonist of the ScottGames era of the Five Nights at Freddy's franchise.

He is the former co-founder of Fazbear Entertainment, the business partner of Henry Emily and the father of Michael Afton, Elizabeth Afton and the Crying Child. He helped Henry establish Fredbear's Family Diner and Freddy Fazbear's Pizza, as well as managing the establishments while Henry built the animatronic mascots. Despite being a successful businessman, Afton led a double life as a serial killer who murdered many children across several Freddy Fazbear's Pizza locations in the 1980s, including Henry's own daughter, Charlotte. At one point in his life, he founded Afton Robotics, LLC and created the Funtime animatronics, which were made to capture and kill children.

Note: this is springtrap version too.

Thirty years after his death, his appearance Afton's flayed corpse still wears the withering Spring Bonnie suit, unable to take it off. Now known by the name Springtrap, the suit has decayed to a sickly olive color and the many holes and tears expose parts of the rusted metal endoskeleton. His mouth has rotted into a permanent wide grin, the teeth being chipped and yellowing. His human-like eyes are a pale gray and he's missing the top half of his right ear, as well as the casing on his feet.

Rare boot-up screens for the game show glimpses of Afton's almost mummified skull inside of Springtrap's mask. His mouth has been permanently speared open by metal rods and his eyes are organic, the spring-locks stabbed into his eyelids and holding them open in a gruesome fashion. What appears to be human innards can also be seen wrapped around the endoskeleton through a large hole in the torso.
