The Main Villain.

Background: Willaim Afton, once a Caring and loving father slowly transcendence into madness. William Afton was the co-founder of Fazbear Entertainment and Afton Robotics, LLC. making him the father of all things Freddy Fazbear. William had three children with an unknown wife: his daughter Elizabeth Afton, his son Michael Afton, and an unnamed third son.

Personality: William's motives for his actions, as well as his backstory, remain unknown to this day, with many believing he became a killer because he was driven by some unknown tragedy (most often interpreted as the loss of his family), a selfish goal for immortality, or he was just a twisted and sadistic monster who wanted to see people suffer, while some believe his motivation might be a combination of the above. However, there is still no official confirmation as to why Afton became the monster he is today.
