Is Michael Afton Really Dead? The Evidence Speaks
If mrs afton exist. This theory is actually backed up with sister location, fnaf 1, 1:35am, dance with me, the freddy files, ballora. Michael being the fnaf 3 protagonist is implied but not 100% confirmed as it's likely that we could be playing as a random person or henry. It's just speculation though. Again, we know michael's voice speaks is at the end of the game, so logically, the afton that speaks at the beginning of the game must be william.
My evidence for that is completley from the silver eyes. Michael afton could've been the michael that was supposedly killed by purple guy, but changed. Michael afton, regardless of which brother he is, is dreaming from the bite victim's point of view, since if mike were dreaming from the older brother's point of view, there'd be no reason for.
