Animatronics

The Animatronics are the main antagonists of the Five Nights at Fredbear's series.

In the first game, the main animatronics consist of the titular Fredbear, as well as Spring Bonnie, JJ, and the elusive Static JJ.

In the second game, the aforementioned animatronics make a reappearance as phantoms, along with their newer counterparts, Freddy Fazbear the Bear, Bonnie the Bunny, plus the new Chica the Chicken and Foxy the Pirate Fox.

Five Nights at Frebear's
In the first game, the animatronics wander about Fredbear's Family Diner after hours in free-roam mode (due to their servos locking up) and sometimes coming after the protagonist Warren Madsen. This is confirmed by Phone Girl on the first night.

Because the security guard is at Fredbear's Family Diner after hours, the animatronics see him as a bare endoskeleton. As this is against the rules at Fredbear's, they will attempt to forcefully stuff the player in an animatronic costume. Unfortunately, there is not enough room for a human to survive in one. The only body parts that would be seen again would be the eyeballs and teeth that pop out the front of the mask.
