Nightmare Hidden Mickey is a fan made antagonist in Abandoned Discovery Island.
He looks similar to Hidden Mickey, but with a bunch of different colors. He has no pupils in both of his eyes and lacks his left arm. His left leg is also lacked while his right leg is not as been replaced by two spikes. His right arm is also a little bit broken and so his gloves either.
Nightmare Hidden Mickey's behavior is similar to almost all the suits of the game. He starts in Character Prep 1. Then he goes to the Staff Area. Then the Meat Freezer where he is staring really closely to the camera. He goes to the lounge, sitting down in the couch. Then finally, he comes to the office. Unlike other suits, you must shut off the power.
- He is a reference to Nightmare Photo Negative Mickey from Five Nights at Treasure Island: Nightmare Before Disney.
- His jumpscare shows him jumping to the player, choking him with his right arm.
- He spins his head around for 2 seconds and then attacking you which looks like he is eating you.
