Supremia Province was one of the domains of Battleworld that is loosely based on Earth-17021. It was under the rule of the Squadron Supreme. The Squadron Sinister of Supremia's neighbor domain Utopolis defeated the Squadron Supreme and killed its members with the exception of Nighthawk, who was selected by the Squadron Sinister's Nighthawk to be used as a puppet regent over Supremia once it was annexed by Utopolis.
