Nightmare is a cold, cruel, yet understanding mafia leader who is creative with his punishments and knows exactly how to make traitors repay him; whether they live or die depends on how he was betrayed. He's about 7'5 and has a singular teal eye, the other covered by a tar like substance that coats his whole body. He's very understanding, and cares for his underlings like family. But nothing covers up his seriousness and cruelty. He takes business very serious. and has tentacles in his back.
