The 'Bite of '87' EXPLAINED (I think)
The victim of the bite of 87 was the purple guys' son, and his older son, caused it. This lead him to kill all of his older sons' friends as well as his oldest son, after his second almost died. Still working as security at the pizzeria, phone guy (purple guy) the older sons' friends notice him, and try to kill him. Purple guy leaves tapes for his son, Mike Schmidt, to survive the night. But, since the Mike and the Purple Guy look so much alike, the animatronics mistake him for Purple Guy. Mike always blames his brother, who is now possessing Foxy. FNAF 4 is a flashback of when Mike was in the hospital. There might have been a miracle or something where the frontal lobe healed, still leaving him more than scarred for life.
But hey, that's just a theory. A FAN THEORY! THANKS FOR READING.
