From Warner Horizon Television and DC Comics, Krypton takes place 200 years before the Superman legend we know, when the House of El was shamed and ostracized. This drama, which is in development, follows the Man of Steel's grandfather (Seg) as he brings hope and equality to a Krypton ruled by the living God RAO, turning a planet in disarray into one worthy of giving birth to the greatest Super Hero ever known.
