Superman is a fictional character and one of the most famous and popular comic book superheroes of all time. Created by American writer Jerry Siegel and Canadian artist Joe Shuster in 1932 while both were growing up in Cleveland, Ohio, and sold to Detective Comics Inc. the same year Superman debuted in Action Comics #1 (June 1938), the character has since appeared in radio serials, television programs, films, comic books, newspaper strips and video games, contributing to his long-standing ubiquity. Superman is born Kal-El on an alien planet — later named Krypton — and is rocketed to Earth as an infant by his scientist father moments before the planet's destruction. The rocket lands on Earth, where he is found by passing motorists who adopt him and give him the name Clark Kent. As Clark reaches maturity, he learns he has superhuman abilities which he resolves to use to help others, fighting anything from petty crime to universal threats. After adopting a Kryptonian fabric costume consisting of a blue shirt with a stylized "S" on the chest, a pair of red briefs over blue pants, a pair of red boots, and a red cape, he becomes Earth's champion, with the media giving him several nicknames including "The Man of Steel", "The Man of Tomorrow" and "The Last Son of Krypton". To keep his identity secret when not fighting evil as Superman, Clark lives among humanity as a "mild-mannered" reporter for the Metropolis newspaper The Daily Star (later changed to the Daily Planet). Clark works alongside reporter Lois Lane, with whom he is romantically involved (and married in the mainstream current comics' continuity).
