Nightmare (FNAF)

Just like Fredbear on Night 6, Night 7, and Night 8, he takes the same role, appearing at 4 AM, and replacing all animatronics, taking up their duties. He must be handled the same way, but Nightmare is more aggressive than Fredbear. Also, he always directly appears at the doorway. Upon being attacked by him, he will appear in a screen similar to Golden Freddy instead of a complete animation. His existence is unexplained, and his purpose is unknown. He is acknowledged in the gallery as a separate entity from Nightmare Fredbear, meaning that he must have some sort of significance. He is the True Main Antagonist of FNAF 4 and its Series.
