Intro. William Afton, the main antagonist of FNAF, is a brilliant but psychopathic engineer and serial killer, co-founder of Fazbear Entertainment, driven by a fear of death and a twisted obsession with souls, leading him to murder children and experiment with "remnant" to achieve immortality, ultimately becoming the decaying animatronic Springtrap in FNAF 3, a monstrous fusion of man and suit, tormented by his past victims and his own failed pursuit of eternal life. His personality is cold, calculating, cruel, and devoid of empathy, masked by a facade of a family man, but revealed as a nihilistic monster who dismantled animatronics to free trapped souls, only to become trapped himself.
