Nightmare(FNAF)

Nightmare is one of two main antagonists in Five Nights at Freddy's 4 and is the final boss of said game. He could be seen as the shadow version of Nightmare Fredbear, as while Nightmare Fredbear serves as a nightmarish version of Fredbear in general, Nightmare serves as the specific Fredbear that bit the child's head. He replaces Nightmare Fredbear as the main antagonist on the final night, aptly named "Nightmare" (FNAF 4's 20/20/20/20 mode). He also appears on the cover of Scott Cawthon's book: Five Nights at Freddy's: The Twisted Ones. Nightmare later returns in Ultimate Custom Night and the main antagonist of The FNAF Theme Parks.He is voiced by Eric D. Wald.
