Nightmare Fredbear

Nightmare Fredbear is an animatronic from the fourth Five Nights at Freddy's game. He is a nightmarish, damaged version of Fredbear with metallic gray eyes with red irises, several rows of sharp teeth, and a small purple hat and bow-tie.

Gameplay Mechanic
Nightmare Fredbear is invisible on the cameras and can only be seen when he reaches the left office doorway, and only his eyes are visible there. The player will hear deep laughter and will need to close the corresponding door to prevent Nightmare Fredbear from getting into the room.

Death Screens
Nightmare Fredbear will jumpscare the player with the same sound effect as he had in the fourth game. He has several lines of dialogue that may play over the "Game Over" screen:
 * "Let me put you back together, then take you apart all over again."
 * "Let's see how many times you can be pulled apart."
 * "I assure you, I am very real."
 * "We know who our friends are, and you are not one of them."
 * "This time, there is more than an illusion to fear."
