Dark-Crawler(Marvel)

Originally called the Night-Crawler, the unnamed Dark-Crawler is a demonic extra-dimensional warlord who ruled over his Dark Dimension until it was destroyed by the Hulk. This enabled him to battle the leader of the Undying Ones, called the Nameless One, and vanquish him. He then ruled over the Undying Ones' realm for a time before the Nameless One reexerted his control.
