How it starts

The most widely accepted version of events begins in the early 1970s, when William Afton and Henry Emily go into business together, opening a restaurant called Fredbear's Family Diner built around animatronic mascots — Henry generally credited as the engineer behind the animatronics themselves, William as the more business-minded partner. Their restaurant eventually becomes Freddy Fazbear's Pizza, the setting of the very first game.

The Missing Children's Incident and the Bite

Most interpretations agree that at some point, five children are lured into a back room at the restaurant by a man in a golden or yellow rabbit-style suit and killed. Their bodies are never found, but their spirits are widely believed to end up possessing the restaurant's main animatronics — Freddy, Bonnie, Chica, Foxy, and a fifth, golden animatronic. Separately, an incident fans call “The Bite” — where an animatronic's jaw injures a child — is generally treated as a real event referenced across multiple games, though which specific game's bite is “the” Bite, and exactly when it happened, is genuinely disputed between fans (this is one of several points where sources actively contradict each other, covered further down).

William Afton, the man behind it

William Afton is almost universally accepted as the man responsible for the murders, generally referred to by fans as “Purple Guy” based on his in-game color palette before his name was confirmed. He's widely believed to have wanted access to something the games call “Remnant” — a substance tied to the lingering souls of the dead, which he uses in his later creations. Most fans read Afton as growing more obsessive and less stable over time, culminating in acts that eventually destroy his own family as well as his victims.

The possessed animatronics

Community consensus holds that each of the original animatronics is possessed by one of the murdered children's spirits, and that a separate character, the Marionette (or Puppet), is possessed by Henry's own daughter, generally called Charlotte or “Charlie” Emily — herself killed under circumstances that different sources describe differently, ranging from a direct act by Afton to an accident involving the animatronic suits' spring-lock mechanisms. The Puppet itself is widely read as more of a protector than a threat within the story — fans generally interpret it as having quietly watched over the other possessed souls, handing out “gifts” (implied to be the missing children’s stuffed bodies, hidden inside the suits) so they could be found and laid to rest, rather than acting out of malice like Afton’s other creations. A separate figure fans call the “Crying Child” — William Afton's own, unnamed youngest son — is generally understood to have been bullied and traumatized around the animatronics as a child, and to die from his injuries after the Bite, his spirit later associated with the golden animatronic Fredbear/Golden Freddy.

Elizabeth, Michael, and the underground facility

Afton is widely believed to have built a second, more advanced line of animatronics — the “Funtime” models, including Circus Baby — partly through a separate company, and to have built an underground facility to house and test them, forming the setting of Sister Location. His own daughter, generally named Elizabeth Afton, is understood to have been killed by or absorbed into Circus Baby, her spirit becoming trapped inside it much like the earlier victims. Afton's older son, Michael Afton, is widely believed to be a recurring, unnamed playable character across several games — most commonly read as the technician in Sister Location and the security guard in the original Freddy's — driven by guilt and a desire to either atone for or undo what his father did, including trying to recover his missing siblings.

Springtrap and Fazbear's Fright

The most consistent version of events has William Afton eventually returning to the abandoned original restaurant, years after its closure, to destroy the animatronics and any remaining evidence — only to be confronted by the vengeful spirits inside them. Cornered, he hides inside an old spring-lock suit called Spring Bonnie. The suit's internal mechanism fails, killing him inside it, and his remains fuse with the suit over the following decades, creating Springtrap — the antagonist of Five Nights at Freddy's 3, discovered decades later when the ruins are turned into a horror attraction called Fazbear's Fright.

Henry’s ending, and what Pizzeria Simulator changes

Freddy Fazbear’s Pizzeria Simulator is generally read as the point where Henry Emily finally re-enters the story directly. The most common interpretation of its true ending has Henry deliberately luring Afton — by then Springtrap — and all of the still-trapped, possessed animatronics into one final building, then setting it on fire with everyone, including himself, still inside. Most fans read this not as revenge but as a mercy: a way to finally free the children’s souls that had been trapped for decades, delivered through a closing monologue many consider one of the most direct pieces of storytelling in the entire series, even if it still leaves plenty unexplained. It’s also one of the few moments the fandom treats as close to settled rather than purely theoretical.

Glitchtrap, Vanny, and the Pizzaplex

Even Springtrap's apparent destruction doesn't fully end things, by the most common reading: Afton's influence is generally believed to survive in a digital, virus-like form fans call Glitchtrap, spreading through VR software in Help Wanted and eventually influencing a real person, Vanessa (“Vanny”), who becomes his agent in the real world. This thread carries into Security Breach and its Ruin DLC, set inside a massive new entertainment complex, the Mega Pizzaplex, where Afton is widely understood to return in a physical, half-destroyed form referred to as Burntrap. This part of the story has its own layer of ambiguity: Security Breach’s ending also introduces a separate shapeshifting entity called the Mimic, capable of copying other characters’ voices and appearance, and a genuine fan debate exists over whether “Burntrap” is really Afton himself or the Mimic using his remains — a question Secret of the Mimic was expected to clarify, but which the fandom is still actively working through. Most fans read Ruin's ending as the point where Afton and his influence are finally, genuinely stopped — and where several long-trapped children's souls, including Charlie's, are finally freed — though how permanent or literal that resolution is remains debated.

Where Secret of the Mimic fits

Secret of the Mimic (2025) is set in 1979 — chronologically the earliest point in the story so far — and centers on a shapeshifting animatronic called the Mimic, generally understood as an early, dangerous prototype connected to the same technology and ideas Afton later builds on. Because it's the newest release, the fan community is still actively working out exactly how it connects to everything above; nothing here about it should be read as settled.

Where fans genuinely disagree

A few points where reasonably well-informed sources actively contradict each other, rather than just filling in gaps:

• Exact names and number of the five murdered children — most lists include Susie, Gabriel, Jeremy (or Fritz), and Cassidy, but sources swap names in and out and disagree on the order they were killed.
• The exact date and location of “The Bite.” Some sources place it in 1983 at Fredbear's Family Diner as a separate incident from the five murders; others treat it as effectively the same event, or place it years apart.
• How Charlotte Emily actually died — versions range from a direct murder by Afton to an accidental death connected to the springlock technology itself.
• Whether the player character in the original 1993 game is Michael Afton at all, versus an unrelated hired guard — both readings have long-running support in the community.
• How literally to take the ending of Ruin — whether Afton is truly, finally gone, or whether the games have left room for him to return again, the way they have multiple times before.
• Whether Burntrap is really William Afton, or the Mimic wearing his remains — both readings have real support, and it’s one of the more actively contested points since Security Breach.
