Superman, also known as the Man of Steel, is one of the most powerful superheroes in the DC Universe. His abilities include incredible super-strength, super-speed, invulnerability, freezing breath, flight, and heat-vision. Born as Kal-El on the dying planet Krypton, his parents Jor-El and Lara sent him in a rocket to the planet Earth where he would be the last surviving member of his race. His rocket was discovered by the kindly Jonathan and Martha Kent, who raised him as their son Clark Kent in the town of Smallville, Kansas. His upbringing provided him with strong moral values, and life-long friends Lana Lang and Pete Ross. In his secret identity he works as a reporter at the Daily Planet in the city of Metropolis. This is where he interacts with his love interest Lois Lane, and his co-workers Perry White and Jimmy Olsen. His greatest nemesis is the brilliant super-villain Lex Luthor. To preserve the memory of his home planet and provide him rest from his double-life and adventures, he maintains a Fortress of Solitude at the North Pole. Superman remains proud of his dual heritage, taking seriously the lessons of his birth-parents and his adopted parents. Although he is an alien to this world, he heavily values his humanity, and fights with conviction for truth, justice, and the American way. There are several other heroes inspired by or directly related to his legacy, including Superboy and Supergirl. He is also a member of the Justice League of America and the Legion of Super-Heroes. Superman was created by Jerry Siegel and Joe Shuster in 1938, first appearing in Action Comics #1. His supporting cast and his villains have had a lengthy publication history, making him one of the three most important characters at DC Comics including Batman and Wonder Woman.
