So basically it starts in the 1950s when a talking bear circus got invented and a few years later (probably in the 1970s) when William Afton saw this and decided to make his own version using anamatronics. Then Henry Emily ripped him off using animatronics with springlock technology and William got pissed at him but still decided to work with him to make a pizzeria (which pizzeria I don't f**king know) even using the character Chica, who Henry made. Blah blah blah Bite Of '83. Afton went insane and decided to get revenge on Henry Emily, because the bite was caused by activating springlocks. Afton killed his kid Cassidy and kept coping and seething over his kid being killed. Afton's kid (crying child) haunted him and his brother because his brother put him in the mouth. William Afton went even more insane and kept killing more kids. I don't know what the bite of '87 is. Something happened and Michael Afton (crying child brother) got scooped in the scooping room, but he kept living for some reason. I think more pizzerias got made because of the events of the first one (I guess Henry made them) and Michael worked at them to find answers and burned them down after he was done working on them. something something William Afton wife made robot versions of all of her kids (at least Matpat said she did)
