'Duke' Mordrogar is a boss and one of the Hellions.
The Hellions are at the bottom of the heap, even in Paragon City. But every so often, one of them displays some real power. The self-styled 'Duke Mordrogar' is one of the few Hellions who display some level of real power even without making an unfavorable contract with a demon. This has given him an inflated ego, and an ambitious drive.
