Doctor Sivana

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."

Sivana is in many ways the prototypical "mad scientist," even coining the phrase "Curses! Foiled again!" He is also prone to uproarious laughter after each of his wicked misdeeds. 

For decades Sivana used technology against Shazam and his family of heroes, but in recent times, the genius inventor has turned to mastering the art of magic as well. In his current incarnation, a bolt of magical lightning hit him in the eye, partially blinding him and leaving him with the power to see magical energy all around him in ways that ordinary people couldn't. But whether he's using his genius to create deadly weapons or casting ancient spells, Doctor Sivana will stop at nothing to master all forms of knowledge in an effort to destroy his archnemesis.
