Springtrap

His actual name is William Afton.

The hair and clothes are a drab olive colour, with darker colours on the insides of his ears. A great portion of his right ear is missing, with a single red wire sticking out of the stump. Springtrap's entire body and clothes are torn and tattered, with gaping holes bearing exposed wires and caging throughout. The middle and other fingers of Springtrap's right hand are notably missing their fingertips, exposing bone. While both of Springtrap's hands and feet are attached and generally intact, his legs are entirely stripped from the mid-shin down, fully exposing the endoskeleton wiring and metal. Springtrap has a wide, permanent grin, as the material surrounding his teeth has deteriorated.

William Afton/ Springtrap is the textbook definition of evil. He is the sadistic serial killer who sparked the downfall of his own company, Fazbear Entertainment, murdered over a dozen children in cold blood, and started the tragic chain of events. It is heavily implied that William's true motive is to gain the secret of immortality and live eternally. Judging by his actions and appearance within the games, William is wicked, cold-blooded and methodical, clearly showing no remorse for his actions. He was even malicious enough to murder his closest friend and business partner Henry's only daughter Charlotte, an event which caused Henry immense emotional turmoil to the point where he nearly committed suicide, showing that William is more than willing to harm his friends, whether it be mentally, emotionally, or physically. "Dittophobia" shows that William had always been twisted, doing cruel experimentation on innocent children for the sole purpose of getting results, proving he feels no remorse for anyone.

He died in a Springbonnie suit after destroying the animatronics (Freddy, Bonnie, Chica, Foxy) with the children's souls inside. He entered the suit and then the springlocks went off, killing him and leaving him to rot in a room for 30 years.

He had three kids, Elizabeth, being the youngest, Evan being the middle child, and Michael, being the eldest. They died to the hands or jaws of his own animatronics, as he was trying to get them to kill other children, but never his own. Evan died to the Fredbear animatronic over at Fredbear's family diner, which was started before Freddy Fazbear's Pizza. Evan's head was put in Fredbears mouth by Michael and the jaw closed down. A couple more years passed, he loved his daughter Elizabeth, warning her not to go near Circus Baby, as he had programmed the animatronic to capture and kill children. But, Elizabeth disobeyed and had herself killed, pulled into the animatronic and crushed. He doesn't know what happened to Michael as he's half dead and had gone through a fire after the horror attraction he had once lived in had got burned down, trapping him.
