MY MY MY Abyss of Randomness

My Theory on FNAF

I've heard of so many FNAF theories on what happened and when things took place and whatnot, so I decided to clear some things up, using several theories I've heard from so far. This chapter will be about who caused the Bite of '87, how Phone Guy died, and much more.

So I hope you enjoy! If I'm missing any information that contradicts with this, or if you want me to post more theories, please let me know and I'll see if I will change it or not.

--------------

Freddy Fazbear's Pizza:

Phone Guy mentioned in the phonecall at Night 1 of FNAF2, "That old restaurant was kind of left to rot for quite a while," saying that there was a Fazbear restaurant that took place before this. Although some people say it was the Freddy Fazbear's Pizza from FNAF1, this isn't true. It is actually called "Fredbear's Family Diner", and does not take place in FNAF1. This restaurant had the four old animatronics you see in FNAF2 (and possibly Golden Freddy).

Later, when Fredbear's Family Diner closed down and the Freddy Fazbear's Pizza of FNAf2 came about, the animatronics from Fredbear's Family Diner were thrown into the parts and service room, while several new animatronics were made (the toy animatronics, Mangle, the puppet(?), Balloon Boy).

Later on after that, the Freddy Fazbear's Pizza from FNAF2 closed down and got "rennovated" again as the pizza place you see in FNAF1. The animatronics from Fredbear's Family Diner got rennovated into the animatronics you see in FNAF1 as well. The new animatronics from FNAF2 are scrapped, so this is why you don't see them in the first game (except for the Puppet. Some people see him in the game at random times).

The fact that Phone Guy never mentions the Bite of '87 in FNAF2 hints that it is a prequel.

The Bite of '87:

A lot of people state that the Bite of '87 was caused by either Foxy or Freddy.

Some say Foxy because of the appearance of a broken jaw, sharp teeth, and a torn suit. His sharp teeth could bite the head of a person, thus making him a good candidate for the cause of the Bite. Along with that, he may be "out of order" because of the fear of having another Bite occur.

Some say Freddy did it because if you look at Freddy's face carefully, you can see human-sized handprints on his face and lower jaw, as though someone were trying to pry his mouth open to free something in it. Along with that, one of the rules state "Don't touch Freddy", probably enacted after the Bite. This could be the reason why people suspect him.

But once it is implied that FNAF2 is a prequel, people began dropping these theories. Because the v1 animatronics are put in the storage room and that they would be too scary for the kids, it is unlikely that Freddy or Foxy bit anyone. So it was more likely one of the new animatronics.

Toy Chica couldn't have been responsible because of her beak. Even without her beak, her teeth are more human-like and can't be used to bite someone's head. The Marionette and Balloon Boy can't be either, due to lack of a hinged jawpiece. 

Mangle, however, has a hinged jawpiece and sharp teeth (two sets on one head, one set on the other), due to being a remake of Foxy. For more support: Mangle's jumpscare animation shows him swinging down from the ceiling and biting what seems like the top of your head, or your frontal lobe. The victim of the bite was bitten on their frontal lobe, and since Mangle bites you, Jeremy is probably the victim of the bite.

On Night 6, Phone Guy asks you to go on a shift for a birthday party. The Bite of '87 takes place at a birthday party. He asks you to stay near the animatronics to make sure they don't harm anyone. Jeremy must've been at the Kid's Cove, guarding Mangle when for some reason he attacked and bit Jeremy, thus killing him. Either that, or Mangle crawled up the ceiling, left Kid's Cove, and attacked Jeremy somewhere.

The Missing Children:

There's one theory that four of the children missing were stuffed into the four animatronics (Freddy, Foxy, Chica, Bonnie) and that the fifth child was Mike. According to the theory, Mike survived somehow after the murderer killed his four friends, returning as the night security guard. When you see the words "It's Me" in hallucinations, it's a way for the children/animatronics to speak to you, calling out to you, like saying "It's me, Mike". Probably the children's souls and the animatronics themselves are fighting against one another, like the children are being forced to kill Mike. Golden Freddy is the suit Mike would've been stuffed in.

I agree with this theory because it makes sense.
