Burntrap, formerly William Afton, is a twisted animatronic with an exposed human jawbone and glowing purple eyes. His suit, a mix of Springtrap and Scraptrap, has missing sections revealing a flesh-like texture and endoskeleton. Silent but sadistic, he controls other animatronics, including attempting to possess Glamrock Freddy. Assisted by Vanny, Burntrap relentlessly pursues his dark agenda, continuing Afton's legacy of manipulation and cruelty.
