Nightmare

Nightmare is a shadow version of Nightmare Fredbear and a hidden antagonist in Five Nights at Freddy's 4. He returns in the Ultimate Custom Night.

Appearance
Nightmare appears identical to Nightmare Fredbear except colored black with a yellow top hat and bowtie.

He is transparent in colour and has the same ombre affect on his teeth like Fredbear. His eyes are red and are mechanical, with a silver backdrop.

Ultimate Custom Night
Nightmare Fredbear & Nightmare: This tag-team duo are invisible to the cameras and can only be seen when they reach your doorways (Nightmare Fredbear takes left, Nightmare takes right), and even then only their eyes are visible. Close the doors on their faces to send them back into the darkness!

=Gameplay= Nightmare will appear at your right door with a sound cue. Only his eyes will be visible. Close the right door to get rid of him.

Trivia

 * His roster image seems to be taken from the Thank You image.
 * This marks the first time Nightmare has an animated jumpscare rather than a still one.
