Shazam's sworn archenemy, Doctor Sivana uses both science and magic to carry out his evil schemes.

Shazam may be the World's Mightiest Mortal, but there's one villain who has consistently given him a run for his money—the evil genius known as Doctor Thaddeus Sivana. Either alone or with the help of other DC super-villains, the bald, diminutive inventor has repeatedly used his brilliant scientific mind to try and defeat Shazam, the hero to whom he once gave the derisive nickname "the Big Red Cheese."
