William Afton is the co-founder of Fredbear's Family Diner & Freddy Fazbear's Pizzeria & Arcadia, alongside his best friend and business partner, Henry Emily!


William Afton is the textbook definition of evil. He is the sadistic serial killer who puts on a kind mask when in public. It is heavily implied that William's true motive is to gain the secret of immortality and live eternally. Judging by his actions, William is wicked, cold-blooded and methodical, clearly showing no remorse for his actions.William shows a rather calm and neutral personality. This is likely to hide his true intentions and evil mindset, while showing that he is a manipulator and seemingly theatrical, being able to easily put on a character to fool people. Occasionally, Afton can be seen dancing gleefully after murdering a victim, taunting them while they are trapped inside of a robotic suit and suffering a slow and painful death. Both of these examples show that William is extremely ruthless and sadistic and appears to take delight, satisfaction, and pride in the murder of innocent people while watching his victims suffer in agony.
