Nightmare, SapphireAngel128 Wiki

Nightmare's appearance is almost identical to Nightmare Fredbear's appearance; the only drastic differences are that the costume color is changed to black, and the bow-tie and top hat are changed from purple to yellow. If images featuring Nightmare were brightened, it would reveal that Nightmare's costume is actually translucent, as if his endoskeleton is cloaked in a shadow. As such, nearly all of his endoskeleton can be seen by brightening images of him. The only exception is around his mouth
