Superbia was a mobile city-state in DC Comics continuity. It initially floated above the radioactive ruins of Montevideo, Uruguay, which was destroyed by a villain called Vandal Savage. For several years, it is the home of the Ultramarine Corps, superheroes who were started by the corrupt United States military officer General Wade Eiling. After recovering from Eiling's manipulations, the Corp struck out on their own in concert with former members of the Global Guardians and any other heroes who wished to join them.
