On the first four end-of-night minigames, William will dismantle the animatronics when they attempt to go to the Safe Room. Upon attempting to enter the room, the "ERR" message will be displayed. If they do not enter the room, Afton will dismantle them regardless.

On Night 5, however, the five spirits of the children he killed appear and enter the Safe Room along with William. After chasing him for a while, he runs into the Spring bonnie suit. Thinking he is safe, he laughs at them, but then the spring locks in the suit malfunction due to his excessive motions and the moisture in the room. Afton then decides to go chase pink unicorns, then instead of dying, the unicorns brought him to heaven. He died because he got killed by Foxy, feeling abandoned. However, he comes back as a zombified animatronic-human hybrid and is more bloodthirsty than ever - he then is scavenged by Phone Dude (who may have been employed by Henry) and haunts Fazbear's Fright until someone (supposedly his son, Michael Afton) burns down the attraction.

He is also the co-creator of th Funtime Animatronics and the former owner of the Circus Baby's Entertainment and Rental, and, by extension, Circus Baby's Pizza World.

It's revealed in the final cutscene received after beating Golden Freddy Mode that Michael Afton is William's eldest son, whom William sent to his rundown factory (Sister Location Facility) to find his daughter and Mike's sister, Elizabeth, but he is 'scooped' by his own sister as, Baby, tricked him. Ennard then takes control over his body. Michael/Ennard then takes on the alias "Mike Schmidt" and works at the 1990s Freddy's Pizza for seven nights until Mike's skin decomposes so badly that he is fired for his putrid smell and for tampering with the animatronics. Ennard and Baby are force ejected from Mike's body and he lives on as a walking bag of rotten flesh and swears to find his father and make him pay for his misdeeds.

Trivia

 * For the longest time, Michael Afton was thought to be the same entity as William Afton, but it was figured out in the final cutscene in V. Hard Golden Freddy preset (Custom Night) that he was not. Also, in the first murders, Michael would be too young to use a vehicle and can't have known about safe rooms as he was an employee after the simultaneous spring lock failures. Only William would know.


 * William seems to have a British accent, with Elizabeth and Michael having one too.
 * In the Silver Eyes and The Twisted Ones, William becomes Springtrap, like in the games, and Michael, his brother (the 'Bite of 83 Child') and sister (Elizabeth) aren't mentioned.
 * William Afton took on the alias of 'Dave Miller' during the mid 1980s to lose the Police and Henry's trail

Pink & Purple Guy
Pink Guy and Purple Guy both appear first in the Fnaf 2 minigames, and they are both William Afton's forms. Springtrap, Glitchtrap, Scraptrap, and Burntrap are his other forms. Pink Guy and Purple Guy were thought to be different people, but this wasn't true.
