(i do not like this one even though he deserves it i steal hate this one this one is a horrible death)
Michael got locked inside a room that he died in.william eventually when fnaf three came out he reemerged to hunt down his son Michael who was the night gaurd(btw i never new this intill research😀)
at the time When Michael sent the place on fire it was on bight five i believe.
William/springtrap survived while😰😥M-Michael died in the fire.before he died he got into a fight with enard and pushed enard down into the sewers Michael layed there dead but heard Elizabeth voice and he got revived once that happened enards eyes showed up in the sewers.
