Nightmare

Nightmare is an animatronic from the fourth Five Nights at Freddy's game. He is similar in appearance to Nightmare Fredbear, but he has black fur and a golden bow-tie and top hat.

Gameplay Mechanic
Nightmare is invisible to the player's cameras and can only be seen when he reaches the office's right doorway. The player must listen for deep laughter from the right side and close the door when his eyes are visible in the doorway.

Death Screens
Nightmare will jumpscare the player with the same sound effect as the other Nightmare animatronics. He has several lines of dialogue that may play over the "Game Over" screen:
 * "You will not be spared. You will not be saved."
 * "The shadow fears me."
 * "I am your wickedness, made flesh."
 * "I am here to claim what is left of you."
 * "I will vomit you back to relive your horror."
