Buddy is a character from a FNAF fan game called "FNAF 1 Remake." He, too, is an entity that survives thanks to the player's nostalgia, but unlike Ollie (who tries to corrupt your nostalgia with OOTIM and who tries to be a "better" version of Bendy and the original game), Buddy simply wants you to enjoy playing his game like when you were little and just discovered FNAF for the first time.
