SuperPatriot, once called Johnny Armstrong, first appeared in Savage Dragon #1 (June 24, 1992).
SuperPatriot was once Johnny Armstrong, a U.S. soldier in World War II. He was captured by the Nazis and used as a guinea pig for scientific experiments, but instead of killing him the experiments gave him superhuman powers. Using his new power of superhuman strength; he broke free and released the other prisoners before destroying the base at which he was being kept so the Nazis could not replicate the process on their own troops. Afterwards, Johnny would don an American flag-styled costume to become SuperPatriot.
SuperPatriot was created by Erik Larsen. The character was derived from a design that Larsen had come with for a failed story pitch that he and Fabian Nicieza had come with for a new X-Factor series in the 1990s; involving a severely crippled Crimson Commando to be rebuilt as a cyborg. Even after Marvel rejected it, Larsen recycled the character as a short-lived character Cyborg X as seen during his run in the Spider-Man comic series.
