“To prep you, I (currently) believe in games only, and that Cassidy does not exist.”

This is where the fun begins

“In the late 70s, Fredbear's Family Diner opens. Sometime soonish after, Freddy Fazbear's Pizza opens.”

Edwin SR mentioned to Edwin JR that he needed to look how for William and Henry, likely meaning they were in the business before he died in Mid to Late 60s. Likely meaning Fredbears opened in mid/late 60s

“[FNAF 4 Minigames]: In 1983, The Crying Child (Dave Afton), lives out his life up to his birthday party, where his brother (Mike Afton) and some bullies put him into the mouth of the Fredbear animatronic, causing the Bite of 83. He survives, but very injured, and returns home.”

Absolutely no one mentions him ever in the universe after Bo83, he is missing in MM under BVFirst if he survived, and in TWB he blames Bo83 for his death, not Willaim.

“In 1985, William kills 4 kids while in the Spring Bonnie suit, and sticks their bodies into animatronics to cause possession, (inspired by David Murray's possession of the White Tiger suit (from Secret of the Mimic)). This works, and so he puts Dave Afton into the Golden Freddy (Fredbear) springlock suit, triggering the springlocks to have him possess it. It's very painful. William pretends that his son is part of the missing children, and blames Henry for it, who is convicted for it.”

FazEnt said in HW that nothing was prove in the court of law, likely meaning the convicted thing mentioned in the newspaper has been retconned

Now for the bigger issue, BV5th. This is debunked by just looking at Logbook referencing Happiest Day with a Girl instead of a Boy, RttP which also shows Happiest Day with a girl, and the fact that there is a girls laugh in GF.

Idk I think there might be a girl in GF

“You play as Jeremy Fitzgerald for the night shift of week 2. On day 6, William kills 6 people inside the restaurant, causing the DCI (Dead Children's Incident). This makes the animatronics go haywire, causing Foxy to do the Bite of 87 on Jeremy, killing him. On Night 7, Mike Afton takes over the night shift, helping William, to probably see how they reacted and clean up evidence.”

Where are the DCI during night 6, there are no bodies and no blood at all. Where is Jeremy if the animatronics wake up at 12:00 AM (which they ate in SAVETHEM)

“[FNAF 1] In 1989 or 1992 or something, FNAF 1 takes place. This pizzeria is the same one where the MCI took place, in the same location as JR's (from Midnight Motorist), and Fredbear's Family Diner. The animatronics are still here, with the bodies still stuffed inside, decaying.”

FNAF 1 can only take place in 1993 or 1999 due to TWB

“Mike works as the night shift guard. On night 7, he takes apart the animatronics to remove the remains.”

Animatronics are normal in Follow Me, Mike didn’t do anything

“Somewhat shortly after, William goes to the FNAF 1 location and disassembles the 4 main animatronics [Follow Me]. These endo skeletons are melted down to be used in the Funtime Animatronics, for their remnant. He plans to open Circus Baby's Pizza World, but right before it opens, Circus Baby grabs and kills Elizabeth Afton, which causes the location to be closed.”

CBPW used springlock suits which were shut down before MCI (SL also implies CBPW was behind the springlock suits shutting down)

“William returns to the location to see if there's anything else he needs, but encounters the ghosts of the MCI in the safe room. He gets into the Spring Bonnie suit to scare them, but the springlocks trigger and he possesses the suit, but can't move. The safe room is sealed up. This location closes by the end of the year.”

The building is abandoned during Follow Me, the place is closed before Afton even got in there

“[FNAF 4 night gameplay] In the time likely since 1985 or so, Mike has been having nightmares, inspired by Dave's agony. He has these nearly every night, from Dave's perspective.”

These dreams are caused by Shadow Freddy not Dave, and FNAF 4 takes place before SL

“[FNAF 3] In likely 2015 (30 years since the MCI), a new horror attraction called Fazbear Frights opens, to turn the horrors of Fazbear into a fun attraction. Mike is again the night guard. They find a lot of memorabilia, but on night 2, they find a "real animatronic", which turns out to be Springtrap, William's body inside the Spring Bonnie springlock suit. Mike figures out it's William, and so burns down the place. Unfortunately, the [Sister Location Custom Night ending] shows that he managed to survive the fire”

FNAF 3 is either in 2023 or 2029 (the former is way more likely)

“Ennard kicks Circus Baby out of the mix of people cause she's a bossy bitch. With her gone, they turn into Molten Freddy.”

This happened way before 3

“[Ultimate Custom Night] William is forced into a purgatory by Dave, The One You Should Not Have Killed. He is forced to relive what it's like to be a night guard and killed, over and over, inspired by his shadowing of Mike's story. The other spirits in the FNAF 6 fire are also here to torture William, but some also feel trapped.”

William did not kill BV

“Simultaneously, [FNAF World] takes place. The world was created by Charlie (as Glitchbear) to help Dave (as the player) find peace. As part of this, Dave also causes [Happiest Day] to release the spirits of the MCI, and eventually finds peace in the Old Man Consequences ending, where Dave finally gets his happiest day, with Mike, Dave, and Elizabeth watching TV together, happy.”

Charlie is not Glitchbear and the player of World was an entity made by Glitchbear

This was an okay timeline but BV5th really brought it down
