Doctor Thaddeus Bodog Sivana is a fictional supervillain appearing in
American comic books published by DC Comics. Created by Bill Parker
and C. C. Beck, the character is a recurring enemy of the superhero
Captain Marvel/Shazam, both of whom first appeared in Whiz Comics #2
(cover-dated February 1940) by Fawcett Comics. A mad scientist and
inventor bent on world domination, Sivana was soon 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.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.Infamously evil, Doctor Sivana appeared in
well over half of all of the Golden Age Captain Marvel comic stories,
and in all of the first four stories, after having deduced Captain
Marvel's dual identity as boy radio broadcaster Billy Batson early on.
Depicted as a brilliant, if evil, scientist, Sivana used all manner of
unusual inventions and techniques against the Marvels. He was at first
a good man who wanted to help humanity, but big business, bosses and
other concerns blocked and checked him and even called him mad, until,
embittered, he turned against humanity and moved to Venus. He somehow
held high status among the beings of the planet Venus. He returned to
Earth, establishing himself as a villain, and clashed with Capt.
Marvel in the latter's first fight. Along with the Marvel Family,
Sivana entered publishing limbo in 1953, following a ruling in the
National Comics Publications v. Fawcett Publications court case
finding that Captain Marvel was an illegal infringement of Superman. Doctor Sivana Biography, NetWorth, Height, Age, Weight, Family, Married, Son, Daughter
