Doctor Sivana is the name of two fictional, related characters appearing in American comic books published by DC Comics. The original Doctor Sivana's alter-ego is Dr.Thaddeus Bodog Sivana, a recurring enemy of the superhero Captain Marvel created by Bill Parker and C. C. Beck and first appeared in Whiz Comics #2 (cover-dated February 1940) by Fawcett Comics.[1] A mad scientist and inventor bent on world domination, the character was established as Captain Marvel's main archenemy during the Golden Age, appearing in over half of the Fawcett Captain Marvel stories published between 1939 and 1953.[2] Thaddeus has kept his role as one of the key archenemies of Captain Marvel (now Shazam) throughout 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.[3][4]
The second character known as Doctor Sivana is Dr.Georgia Sivana, P.h.D, the daughter of Thaddeus who first appeared in Mary Marvel #1, created by Otto Binder. Georgia was originally portrayed as a underling of her father who takes after her father in appearance and skills, both possessing keen scientific minds although the character is instead an arch-nemesis for Mary Marvel. Years following the New 52 reboot and during the Infinite Frontier initiative, Georgia's character is revamped into an older professor, archaeologist, and estranged daughter of Thaddeus whose reputation is tarnished due to her father's obsession with magic in the scientific community and seeks to improve it at any cost.[5]
Thaddeus Sivana has 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.
