Krypton (comics)

Krypton is a fictional planet appearing in American comic books published by DC Comics, most commonly appearing or mentioned in stories starring the superhero Superman as the world from which he came. The planet was created by Jerry Siegel and Joe Shuster, and was named after the chemical element krypton. It was first mentioned in Action Comics #1 (June 1938) and made its first appearance in Superman #1 (June 1939). Krypton is destroyed immediately after Superman, as the baby Kal-El, is sent from the planet in a spacecraft by his parents, although the exact details of its destruction have varied over publication history. The planet is portrayed as having been far more technologically advanced than Earth, and having orbited a red sun. Kryptonians were the dominant species on Krypton, and its inhabitants included Kara Zor-El, Krypto, Beppo, Kara Zor-L (in her case, an alternate-universe version designated "Krypton-Two"), and the supervillain General Zod. Krypton appears in several television series such as Adventures of Superman, Lois & Clark: The New Adventures of Superman, Superman: The Animated Series, Smallville, Supergirl, Krypton and My Adventures with Superman. It also appears in the films Superman (1978), Man of Steel (2013) and Supergirl (2026).
