Black Adam later leads the Sivana's to the wizard Shazam where Sivana tricks him into getting the powers of Captain Marvel. He takes down Batman however Billy Batson tricks him into saying Shazam which turns him normal and the wizard takes his powers back. He later appears in the episode "The Malicious Mister Mind" as the leader of the Monster Society of Evil and has them steal parts for a death ray that he is constructing and to fight the Marvel family. However the society appears to not like him and later they choose Mr. Mind as the leader over him. As the episode progresses Sivana appears to grow jealous of Mr. Mind between him improving the death ray and him being able to defeat the Marvels. He later betrays mind and tries to kill Mind with the death ray but he reveals it to be a growth ray which turns mind into a giant monster who attacks the city however Sivana is happy since he proves that Mr. Mind is really a bad leader.

He also appeared as a villain in the show The Kid Super Power Hour with Shazam!

Dr. Sivana also appears in the Mad Sketch Shazam and Cat. In the sketch, Dr. Sivana steals electricity from a telephone wire to charge up his battery. Billy Batson tried to stop him as Shazam, but was fooled to change back by Sam and Cat, allowing Dr. Sivana to get away. Shazam tried to stop him again on top of a satelite, but was fooled to change back into Billy Batson again by Dr. Sivana. Just then, Sam and Cat appeared on a motorcycle and ram Dr. Sivana with it. Dr. Sivana, however, revealed his plan was for good as he explained he was trying to destroy the satelite to stop Dan Schneider from making any other bad shows. Billy, Sam and Cat agreed to help as they were seen attacking the satelite with whips made of chains. Dan Schneider saw this and decided to save himself by making a tv show called "Definately Alive with Dice."

A mad scientist who appeared in a 1940's Fleischer Studios' Superman cartoon somewhat resembles Sivana, likely since both were based on classic mad scientist tropes of that era.

He will be the main antagonist in the DC Extended Universe film Shazam!, and will be portrayed by Mark Strong, who also portrayed Frank D'Amico in Kick-Ass.
