After Micheal's experience with this, he wanted to find out what was going on. He went to William who told him the story. William asked Micheal to become a security gaurd and watch the animatronics. What he didn't know is that there were 7 more kids missing there.

The seventh kid was the one that was in the Fruity Maze minigame. Her do died, and Springtrap lured her to the pizzeria, and kept her hostage.

This would explain the weird Toy Chica anime cutscenes, explained by Dawko right here.

Micheal didn't want them to know he was William's son. He remembered two kid's names that went missing in the old pizzeria. Jeremy and Fritz, and put the two names together. Micheal Afton got the name Jeremy Fritzgerald. This is FNAF2. He tampers with the animatronics to get the children free, and was fired.

Then the Bite of 87 happened. All I'll say is that it was nor a child, but a man that we already know.

The place shut down, and the toy animatronics were scrapped due to the odor they smelled, which was the blood and corpse of the children, which were dust by then. BB and Mationette weren't scraped, and were put into the location with the other animatronics. William plans to get rid of the animatronics once and for all, and uses Foxy to his advantage. The Foxy minigame in FNAF 2. The cops found out about William's plans, and got him into jail.

After this, the children were set free by Marionette, and they went to go find animatronics to posess. We'll get to that later. Micheal decides to try again, and changes his name to Mike Shmidth. He tampered them again, and was fired. Micheal meets Henry, and Micheal lived with him, qith an,animatronic named Lefty. Then to goes to talk to William after a few years of jail. William asks him to go to Sister Location, and free his sister and mother. FNAF 6, which we know how it ends up ending like.

After night 2, Micheal was back at Henry's place, and Lefty escaped to the old pizzeria, but couldn't go in.

Michael realized that this was all William's fault, and he he then went to confront him. During night 4 or 5, William got free, and went back to the location he was caught at.

He realized the mistake he made, and wanted to set them free. The souls attacked him, and as we see, it didn't go well. But who is the crying child, well there's only two explanations. Marionette or Golden Freddy. You decide, I think it's Golden Freddy. So after this, everyone that helped out with all of the pizzerias and diners came together to make Freddy's Fright, where everything that was about the pizzerias and diners was kept there. Micheal meets Henry, And they become friends, and make a plan to destroy everything. Burn the place to the ground, with everything in it. It didn't work though, as we know everything that was found was sold in an auction. So they made another plan.

They made another pizzeria, that was secretly a trap for all the animatronics. Henry would help Micheal survive the nights, knowing his experience. As we know what happens, I don't think I need to go further.

William is left to rot in hell, while Micheal, Henry, and a lot of others go up to heaven. William is tormented by one soul that does not want to rest, and that'll be explained in The FNAF UCN Story. This isn't a story only about a murderer. It's a story of a greedy owner that felt betrayed by an old friend, who tried to go over the top, and win. It's sad, and just look at what it did to him. If this story has a lesson, it's to never let jealousy get a hold of you, to not let it overcome you, or else, in the end, it won't work out for you. Even though I have the Timeline done, there are still plenty of other things to look at. What about all the games, what does each game hold. What does every character hold. That's what I'll explain, when I see you next time, I'll see you later.
