so it all starts with William afton, and his buddy named Henry. Afton was a dad, had a daughter named Elizabeth, a son named Micheal, and an unnamed (probably had name, was just never brought up) younger child, of whom is known as crying child, due to his constant crying in literally any situation. Now Afton and his buddy were geniuses that somehow created machinery centuries ahead of its time (fnaf starts in the 1980-2000’s), and start a new diner of which had two functional kiddie entertaining robots, those being fredbear (a bear), spring Bonnie (a bunny), and the security puppet (a marionette).Considering the amount of restaurants that existed, they were pretty successful. now another thing to mention, is that Afton (and only afton) is also a psychotic murder, and murdered what is possibly his first kiddie victim, although maybe not, some voice lines in UCN prove that chica (Susie) was the first victim.
