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.
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. 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.
