He's from the planet Krypton, sent to Earth as a baby. Then the comics show his growth on Earth, his discovery of his powers, and how he decides to use them for good. He faces various villains like Lex Luthor who try to defeat him. Each issue of the comic is like a chapter in the overall story, gradually building the character and the world around him.
