A random company called by Coso generic name(Entertainment) opened a restaurant, which for some reason closed, so a new one opened. A guy named ´´James´´ (forgot the name) lured two brothers into the staff room, and cosplayed as William Afton, so the souls of the brothers possessed the animatronics and blablabla. For some reason, ´´James´´ went to work as a night guard, but he is captured and placed inside Old Coso. Coso Entertainment opens a new restaurant again, but this time the night guard is Edward, that is, the parents of the dead children. After Coso, Cosa, Meow and ´´James´´ vugo Old Coso mutate, they are placed in the new restaurant, but police find ´´James´´ inside SpringCoso and the place is closed. After further mutations, the remaining animatronics were placed in storage, to be discarded at the end of the week. ´´James´´ reassembles himself with pieces of other animatronics and becomes Metalo (cringe), again Edward is hired as a night guard. At the end of the week Metalo destroys the other animatronics using the parts to enhance himself becoming Metalfield. Edward is trapped in storage due to the lack of light, having to open the exit door manually using the tablet, so the two fight an epic battle, which once you get the hang of it becomes easier than night one. Edward manages to escape and has to listen to a boring speech from ´´James´´.

• Demolished Proto Coso theory : He doesn't appear in FNaC 2, so he was probably in the restaurant from FNaC 1, but his jaw is a different color than the rest of his head, so he stole the jaw from one of the Advanceds, but he wasn't in FNaC 2, so he must have had contact with some Advanced in FNaC 3, but he doesn't have any in the game, so Proto Coso killed them or just took the jaw of one, because Metalo must have killed the Advanceds to build himself then ´´ ?´ But still, Proto probably stole Coso's arm before FNaC 2, so that's why Demolished has part of a broken arm on his spine, if I can call that a spine.
