From Wiki-
Thaddeus Bodog Sivana is a
supervillain appearing in
American comic books published by
DC Comics. Doctor Sivana is the archnemesis of
Captain Marvel created by
Bill Parker and
C. C. Beck, first appearing 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.

Sivana has kept his role as one of the key archenemies of Captain
Marvel (now Shazam) throughout 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.
[3][4] 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.
[5] He returned to Earth, establishing himself as a villain, and clashed with Capt. Marvel in the latter's first fight. Eventually back to me:
