Doctor Sivana is one of the non-playable characters in LEGO Dimensions 2: The Rise of Enoch, from the DC Comics franchise.
Doctor Thaddeus Bodog Sivana, Sr. is Shazam's arch-nemesis. A brilliant evil mastermind, he is arguably the archetype for the "mad scientist". Sivana was the first to figure out Shazam's identity, and has been a constant pest to the Big Red Cheese (as he prefers to call the Captain). He has been associated with the Monster Society of Evil and the Secret Society. He also had a son, Thaddeus Sivana, Jr., and a daughter, Georgia Sivana, who both resemble him.
