William Afton

William likes theater, music, animatronics, junk-food and sweets, purple, office stylw, children, circus and science. He is brittish btw

William had a wife, who gave birth to his children: Michael, Elizabeth and the youngest son. He doesn't like his children because he never actually wanted them, but he should raise them to look like a nice guy. He is very friendly and is a friend to Henry Emily. They were so close they made deadly plans together, made business together and...well, sometimes they had weird affection to each other (actually they both bi, but they do not know it because they are in 80s).

William Afton is the textbook definition of evil. He is the sadist who started the tragic chain of events. It is heavily implied that William's true motive is to gain the secret of immortality and live eternally. William is wicked, cold-blooded and methodical, clearly showing no remorse for his actions. William is more than willing to harm his friends, whether it be mentally, emotionally, or physically.
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. One of William's voice lines in Freddy Fazbear's Pizzeria Simulator suggest that he is opportunistic and will proceed with his intentions, regardless of the risks.

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. The fact that he created the Funtime Animatronics, which are very advanced and technological, shows that he has a genius level intellect, a talent for robotics, and is very proud of his creations.

He is arrogant, boastful, and overconfident, and even suggests that he wants his victims to fear and respect him. This is in stark contrast to his subtle, poetic, and calculated voice. His mannerisms are incredibly flamboyant. Given his nature, William is most likely not insane, he just seemingly does not care for the difference between right and wrong, and simply chooses to be evil for no other reason than to achieve his twisted and unethical desires.

It is heavily suggested that William's greatest fear above all is his own death. This fear is so immense that he has developed an unbreakable iron will to live, no matter the circumstances. Ultimately, this is what pushes him to survive even in the deadliest situations time and time again. He showcases his willpower by confidently stating "I always come back".
