Captain Nazi first appeared in Master Comics #21 (December 1941) and was created by William Woolfolk and Mac Raboy.

[1] The super-strong Captain Nazi was genetically altered by his scientist father, and developed into the "perfect specimen" to fight for Adolf Hitler and the Axis Powers during World War II.

[4] Junior, crippled in his Freddy Freeman form by the attack, continues to hold a vendetta against Nazi, and the two frequently battle one another.

Nazi also serves as a member of Mister Mind's Monster Society of Evil, one of the most powerful organisations of villains in the world which included Adolf Hitler, and assists their first plan to steal magic fortune-telling pearls from a princess, leading Captain Marvel to their hideout, and revealing their existence, during the World War II years, before making his final Fawcett Comics appearance in the story "General Nippon's Elusive Earthplane", published in Captain Marvel, Jr. #19 in 1944.

Captain Nazi appeared only sporadically in DC Comics' 1970s/1980s revival of the Marvel Family characters under the title Shazam!, save for reprints of the original Fawcett stories.

Following writer Roy Thomas and artist Tom Mandrake's new interpretation of the Captain Marvel mythos in the 1987 four-issue miniseries Shazam!

: The New Beginning, Captain Nazi was re-introduced in a 1988 four-part story in Action Comics Weekly issues #623-626.

[11] He has since appeared as leader of a Nazi-themed team in Justice Society of America named "The Fourth Reich" after the "One Year Later" jump, and is an opponent of Wonder Woman in "The Circle".
