The Squadron Supreme is a fictional superhero team appearing in American comic books published by Marvel Comics. The core members of the Squadron Supreme are Hyperion, Nighthawk, Doctor Spectrum, Power Princess, and the Whizzer. The team also has several minor members. As with the Squadron Sinister super-villain team, members of the team were initially based on characters published by rival DC Comics, and the team itself was a stand-in for the Justice League. A number of characters that were not based on DC heroes were added to the roster later.
