Superman is a fictional superhero appearing in American comic books published by DC Comics. The character was created by writer Jerry Siegel and artist Joe Shuster, high school students living in Cleveland, Ohio, in 1933. They sold Superman to Detective Comics, the future DC Comics, in 1938.

The origin story of Superman relates that he was born Kal-El on the planet Krypton, before being rocketed to Earth as an infant by his scientist father Jor-El, moments before Krypton's destruction. Discovered and adopted by a farm couple from Kansas, the child is raised as Clark Kent and imbued with a strong moral compass. Early in his childhood, he displays various superhuman abilities, which, upon reaching maturity, he resolves to use for the benefit of humanity through a "Superman" identity.

Superman debuted in Action Comics #1 (cover-dated June 1938) and subsequently appeared in various radio serials, newspaper strips, television programs, films, and video games. With this success, Superman helped to create the superhero archetype and establish its primacy within the American comic book. The character is also referred to by such epithets as the Big Blue Boy Scout, the Man of Steel, the Man of Tomorrow, the Last Son of Krypton, and the Greatest Hero of All Time.
