Nightmare is a game character that makes his appearance in Five Nights at Freddy's 4. He is like Nightmare Fredbear but he is black with a yellow bowtie and hat, and he only appears on Nightmare Night. He must have the deepest and scariest voice out of all the nightmares. And he should breath menacingly after or before he talks, kind of like how he sounds in Ultimate Custom Night as his voice reference.
