Nightmare Epic Mickey is an fan made antonigist in Abandoned Discovery Island.
He appears as the normal Epic Mickey except that one of his eyes has a little human eye and one of his ears is broken. He also has spikes on his right leg and right arm.
Nightmare Epic Mickey starts in the Janitor's Closet where he is looking at you at that camera. Then he goes to the bathroom where you can see him hiding behind the toilet. Then he goes to the Meat Freezer. Then the lounge and then the office. You must shut off two cameras to survive making him a dangerous antonigist.
When he moves he can say the following things.
- I was epic but now i'm a monster.
- Why did you hurt me?
- I will murder you for the damage you did
- You can't murder me but I could murder you.
