Sivana has kept his role as one of the key archenemies of Captain Marvel, now also known as Shazam, through to the character's appearances in DC Comics, which eventually acquired the rights to Fawcett's superhero characters. In 2009, Doctor Sivana was ranked as IGN's 82nd-greatest comic book villain of all time.
The character made his cinematic debut in the DC Extended Universe 2019 film Shazam!, portrayed by Mark Strong, who reprised the role in a post-credits scene cameo in the 2023 sequel Shazam! Fury of the Gods.
