Nox Decious was Merlin's younger brother and arch-nemesis, a relative of Mario and Luigi, one of Ganon's henchmen, and the Darkness' creator and former boss. He became corrupted by evil when he learned from Merlin that the Chosen One wasn't himself. The two then fought, which ended in Decious donning a mask to cover his burnt face caused by Merlin. Decious' main goal was to take control of Earth and destroy all good and recruited his henchman the Darkness to assist him.
