Bonnie (also fully known as Bonnie the Rabbit[1] or Bonnie the Bunny, by fans) is an antagonist in Five Nights at Freddy's. Bonnie is an animatronic rabbit and children's entertainer housed at Freddy Fazbear's Pizza, along with Freddy Fazbear and Chica. He is the guitarist in Freddy's band, positioned at the left side. At midnight, he is left in a "free-roaming mode" until 6 AM, to prevent his servos from locking up.

Along with the other animatronics, Bonnie will try to forcefully stuff any human he sees after hours into a Freddy Fazbear suit, resulting in death.
