Lion-Man is the very first African-American superhero to ever appear.
He made his debut in All-Negro Comics #1 in 1947. It was the only issue ever published, and his only appearance. Lion-Man was created by writer=penciller George J. Evans, Jr.
Lion-Man's real name was never given. He was said to be an American-born, college educated scientist. The United Nations sent him to the Gold Coast (Gulf of Guinea in west Africa) to guard the "Magic Mountain", which contains the world's largest deposit of uranium. His job is to stop anyone from taking the element.
Lion-Man had a sidekick, a big-headed caricature of a black youth. His name was Bubba, and he was a war orphan.
