The Old Animatronic - FNAF Security Breach Fanfic

What would happen if a 30ish year old animatronic just 'appears' in the basement of the Mega Pizza-Plex? And what would happen if this animatronic woke up? What would happen to the guards that find it? Nothing bad... hopefully.

This is an AU where Freddy, Bonnie, Chica, Foxy, Roxy, and Monty are all back as Glamrocks.
Inspired by this one image i seen of a theoretical glamrock mangle.
