Michael Afton (FNaF)

Michael Afton is a tragic antagonist (in the backstory)-turned-main protagonist of the Five Nights at Freddy's game series. He is the older brother of Elizabeth Afton (Circus Baby) and the son of William Afton (Springtrap). In the past, he was presumably an unintentional accomplice of his father's crimes, but after discovering his father's crimes, he wanted answers and attempted a job as a night guard of Freddy Fazbear's Pizza under the false name of Mike Schmidt, eventually succeeding. However, he isn't aware that the vengeful spirits of the children his father killed will return and attempt murder anyone they see in the pizzeria wearing an uniform while possessing the animatronics, but Michael eventually succeeds to survive.. After he completes the nights in the first game, he returns again under the name of Jeremy Fitzgerald, in the brand new FNaF location, now with redesigned, brand new technology animatronics who serve as the new antagonists. Still attempting answers even after being haunted, he still keeps his job as a night guard in the third game, but now he guards the Halloween renovated pizzeria who was called Fazbear's Fright, but is not aware that his undead father is haunting the pizzeria in the Spring Bonnie suit.

In the prequel-sequel game, FNaF 4, he is a child, as the story is from his childhood, after his brother murdered him unintentionally in Fredbear's mouth. However, he was rebuilt as a robot by his father, who set illusions to torment him for leaving the house and visiting Fredbear's location, illusions in the form of Nightmare animatronics and the main antagonists of the game.

In FNAF: Sister Location, he presumably learns that the spirits of the children are possessing the animatronics, but he is now haunted by late technology remote-controlled circus animatronics, which were in fact built by his father to kill children for unknown motives. In the end, the four main animatronics combine their endoskeletons to create the entity known as Ennard, and take Michael's form to escape the location, after scooping and entering his body. However, Ennard causes him to transform into a purple man, like his father is, but Michael spits Ennard out and is mysteriously brought back to life.

In FFPS, he is haunted one last time by Afton, Scrap Baby, Molten Freddy (the reincarnation of Ennard after Baby removed herself out from the amalgamation for unknown motives) and Lefty (a black bear animatronic with red hat and bowtie, part of the Rockstars Assemble, and The Puppet's new animatronic vessel). After salvaging all the 4 animatronics for parts, he makes a noble sacrifice, setting the place on fire, with Afton's spirit being condamned to Hell and the other spirits being presumably freed, with him also dying in the end, but as a hero.
