Freddy Fazbear

Freddy Fazbear is the titular antagonist of the Five Nights at Freddy's franchise, who later appears as multiple variations in the succeeding games, and is the mascot of Freddy Fazbear's Pizza.

He is an animatronic bear who, like most of the animatronics in the games, is supposedly left in a "free-roaming mode" at night, during which he wanders around the pizzeria, along with the other animatronics, until 6 AM, to prevent their servos from locking up. Like the other animatronics, Freddy will try to forcefully stuff any human he sees after hours into an animatronic suit, resulting in their death.

Secretly Freddy and the other animatronics are haunted by children murdered by a man named William Afton, him and the rest are now seeking revenge against their killer attacking anyone in the pizzeria in blind rage.
