Superman, also known as Kal-El or Clark Kent, is a fictional superhero who appears in American comic books published by DC Comics. The character, created by Jerry Siegel and Joe Shuster, first appeared in Action Comics #1 in June 1938, and immediately became a sensation. The typical Superman storyline has him using his immense strength and extraterrestrial flying abilities to rescue people from danger, in between periods of working undercover as a journalist to spy on organized crime and other subtle examples of evil. Continuously published every since, Superman has become a cultural icon, appearing in radio, television, film, and video games. While not the first superhero, Superman nonetheless appeared early enough to become the blueprint for the characters who followed, and was instrumental in establishing the superhero genre.
Superman was a comic book character, created in the United States, and proved to be very popular with its readership. The comic was banned in the Confederate States under the Freedom Party because Superman often battled Confederate forces, but his popularity was so great that the ban was widely ignored until the C.S. government created the similar Hyperman to fill the Confederate demand.
Chaim Weinberg told Vaclav Jezek that his relationship with his wife Magdalena was going down the drain, and not even Superman would be able to stop it. Jezek asked who and Weinberg explained Ubermensch was a comic book hero in the US and showed him some comic books he had. Weinberg explained Metropolis was similar to New York City but hastened to elaborate that he meant the background skyscrapers and cars and such and not the hero rescuing a scantily clad girl with one hand while carrying an enormous locomotive with the other while a bad guy's Tommy-gun's bullets bounce off his chest as though he were a panzer.
