With one magic word, young orphan Billy Batson transforms into a man imbued with the powers of the gods. But even one gifted with the Wisdom of Solomon can learn from a Superman. While Superman must stop members of a cult from stealing ancient artefacts from the Metropolis Natural History Museum, Billy must battle giant robots rampaging through Fawcett City. These separate events lead the heroes to cross paths, and a mighty friendship is formed as Earth’s most powerful defenders team up to stop such menaces as Lex Luthor, Dr. Sivana, Eclipso and the monstrous Lord Sabbac.
