Kaleb of Hydros was a galactic resistance fighter against the Emperor, Lex Luthor LX. Luthor was systematically destroying all planets that met the specifications and criteria necessary for their citizens to gain super-powers under the sun of another world. While attempting to destroy the planet Hydros in this manner, a group of rebels managed to sneak onto the planet and rescue its last remaining survivor, a man named Kaleb. Once off-world, Kaleb began to absorb the radiation of yellow solar energy, and became the hero the rebels had been waiting for, the return of the legendary Superman.
