Summary
Highlights
William Afton and Henry open 'Fazbear's Family Diner' which later expands to 'Freddy Fazbear's Pizza'. Henry creates the Puppet to protect his daughter, Charlie. William murders Charlie, and her spirit possesses the Puppet. William's son, Evan, is accidentally killed by an animatronic in the 'Bite of '83', leading William deeper into madness.
William murders five more children, stuffing their bodies into the animatronics. He discovers 'Remnant', a material that allows souls to possess objects, believing it's the key to immortality. He uses this knowledge to create 'Circus Baby' to murder children, and his daughter, Elizabeth, is killed by Baby.
William sends his son, Michael Afton, to free Elizabeth's soul from Circus Baby. Michael works at William's new facility, where animatronics are scooped and their endoskeletons merge into Ennard. Ennard then scoops Michael, using his body as a disguise to escape, while Remnant keeps Michael alive as a reanimated corpse.
Michael searches for William. William dismantles the original animatronics, awakening the spirits who corner him. He attempts to scare them by wearing his old Spring Bonnie suit, but the spring locks fail, crushing and seemingly killing him, transforming him into Springtrap. The suit is later found and becomes an attraction in a new horror-themed Freddy's location, where William reanimates.
Henry devises a plan to end the cycle. He opens a new pizzeria to attract all the roaming animatronics, including Michael (as a security guard) and William (Springtrap, later ScrapTrap), along with Circus Baby (now Scrap Baby) and Ennard (now Molten Freddy). Henry burns the pizzeria down, freeing the souls and seemingly ending William Afton's reign of terror.
Before his fiery demise, William uploaded his consciousness into binary code. When a virtual FNAF experience is developed, William's digital consciousness, Glitchtrap, enters the game and possesses a woman named Vanessa. In 'Security Breach', a new mall-sized pizzeria is built, where William, through Vanessa (Vanny), controls new Glamrock animatronics. Glamrock Freddy malfunctions, rescuing a homeless child named Gregory. Together, they confront William, who is eventually captured by 'The Blob' (a mass of animatronic souls), as the complex burns down.
