Freddy Fazbear

Freddy Fazbear is the main antagonist in Five Nights at Freddy's. He is an animatronic bear who, like the other animatronics in the game, he roams around Freddy Fazbear's Pizza, along with the other animatronics, until 6 AM.

Of course, just like the other animatronics, he'll attempt to kill you.
