Superman was born on the planet Krypton and was given the name Kal-El at birth. As a baby, his parents sent him to Earth in a small spaceship moments before Krypton was destroyed in a natural cataclysm. His ship landed in the American countryside, near the fictional town of Smallville. He was found and adopted by farmers Jonathan and Martha Kent, who named him Clark Kent. Clark developed 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 colourful 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 supporting characters include his love interest and fellow journalist Lois Lane, Daily Planet photographer Jimmy Olsen and editor-in-chief Perry White. He has many foes such as his archenemy, the genius inventor Lex Luthor. He is a friend of many other superheroes in the DC Universe, such as Batman and Wonder Woman.
Although Superman was not the first superhero character, he popularized the superhero genre and defined its conventions; superheroes are usually judged by how closely they resemble the template established by Superman. He remains the best selling superhero in comic books of all time and endured as one of the most lucrative franchises even outside of comic books.
