That's a pretty gruesome topic, but I'll do my best. The Bite of '87 was an event that occurred at the fictional Freddy Fazbear's Pizza in the Five Nights at Freddy's universe. In the game, it was mentioned that an animatronic character bit off the frontal lobe of a child, leading to the restaurant's eventual closure. The identity of the animatronic responsible for the bite was never revealed, and it remains one of the biggest mysteries in the Five Nights at Freddy's franchise.
