The Squadron Supreme is a superhero team appearing in American comic books published by Marvel Comics, of which there are several notable alternate versions. The original team was created by Roy Thomas and John Buscema, derived from the previously created supervillain team Squadron Sinister.

Roy William Thomas Jr. is an American comic book writer and editor. He was Stan Lee's first successor as editor-in-chief of Marvel Comics and possibly best known for introducing the pulp magazine hero Conan the Barbarian to American comics. Thomas is also known for his championing of Golden Age comic-book heroes – particularly the 1940s superhero team the Justice Society of America – and for lengthy writing stints on Marvel's X-Men and The Avengers, and DC Comics' All-Star Squadron, among other titles.
