"I think you'd better watch out for Phantom Bonnie. He is a lot more, um, dangerous than the others..."
Phantom Bonnie is Bonnie from the first game, however burned and charred. His eyes are gone, with just small white pupils.
Phantom Bonnie is very active and likes to scare people. He seems to really love CAM 02 because his costume is in there. If you bug him, he will disable every system, as he does not like being bothered.
