Superman was born on the planet Krypton and named Kal-El. As a baby, he was sent to Earth in a small spaceship by his scientist father Jor-El moments before Krypton was destroyed in a natural cataclysm. His ship landed in the American countryside; he was found and adopted by farmers Jonathan and Martha Kent, who named him Clark Kent. Clark displayed various superhuman abilities, such as incredible strength and impervious skin. His foster parents advised him to use his abilities for the benefit of humanity, and he decided to fight crime as a vigilante. To protect his privacy, he changes into a colorful costume and uses the alias "Superman" when fighting crime. Clark Kent resides in the fictional American city of Metropolis, where he works as a journalist for the Daily Planet. Superman's love interest is his fellow journalist Lois Lane, and his classic arch-enemy is the genius inventor Lex Luthor. He is a friend of many other superheroes in the DC Universe, such as Batman and Wonder Woman.
