Hello people i got some theories on who burnt down Fazbears Fright
Henry nolastname: Well maybe Henry wanted to get revenge from William Afton for killing his daughter so he went to Fazbears Fright to burn him and maybe we might play as Henry.
Michael Afton: Michael might have wanted to end this all by burning down Fazbears Fright and it is theorized that FNAF3 takes place after SL maybe it is possible
Springtrap: Maybe he wanted to burn everything including him but it wont make sense he knows he will go to hell
Faulty wiring: orrr maybe it was just bad wiring.
Anyways thanks for reading this.
