Krypto the Superdog is a fictional superhero dog appearing in American comic books published by DC Comics, commonly in association with Superman. He is the main protagonist of the television and film series of the same name. In most continuities, Krypto is Superman's pet dog, usually depicted as a white dog of a generic pedigree.
For the first time in history, Superman assembles an all-star league of superheroes, Batman, Wonder Woman, Green Lantern, and more to save the Earth from an equally assembled league of Supervillains led by Lex Luthor, the Legion of Doom.
