Black Adam

Black Adam is a major antagonist in DC Comics, being one of the three arch-enemies of Shazam . Though his origins vary between versions, in all that he is depicted as the former champion of the Wizard, who was corrupted by his power, resulting in him becoming a villain and an adversary towards the Marvel Family. In recent years, however, he has frequently been depicted as a more neutral or anti-villainous character.
