In Five Nights at Freddy’s lore, the “Bite of ’87” does not have an officially confirmed culprit from Scott Cawthon, so there is no single canon answer to who did it.

What the Bite of ’87 Is

  • The Bite of ’87 is an in-universe incident where an animatronic bit a person’s head and damaged their frontal lobe.
  • It is mentioned in the first FNAF game’s phone calls as a major past accident at Freddy Fazbear’s Pizza.

Most Popular Suspects

  • Mangle: Many fans argue Mangle is the likeliest culprit because its jumpscares go for the player’s forehead, and it hangs from above like it could bite the top of someone’s head.
  • Toy Chica: Others point to Toy Chica’s Ultimate Custom Night line “Where’s my beak? Lodged in your forehead” as a wink toward her being responsible.
  • Other toy animatronics are sometimes suggested, but Mangle and Toy Chica are the main fan suspects.

Fandom Consensus vs. Official Canon

  • A large part of the community treats “Mangle did the Bite of ’87” as the default theory, especially in forum and Reddit discussions.
  • However, until Scott (or an official FNAF source) directly confirms it, the true culprit of the Bite of ’87 remains unresolved and open to interpretation.

Mini “Story” View

  • Imagine a busy 1987 birthday party at Freddy Fazbear’s: kids crowd the new toy animatronics, staff are distracted, and one malfunction or aggressive move is all it takes.
  • In that chaos, an animatronic lunges too close, jaws clamp down on someone’s forehead, and the incident becomes the infamous Bite of ’87 whispered about in every later game.

Quick TL;DR

  • No official, canon-confirmed answer.
  • Fandom’s top pick: Mangle.
  • Strong alternate fan theory: Toy Chica.
  • The question “who did the Bite of ’87” is still a deliberately unsolved mystery that keeps FNAF discussions active.
