Black Panther’s name was temporarily changed for being too controversial in the stories of Marvel Comics due to political reasons.
Marvel’s once temporarily changed Black Panther’s name due to it being too controversial during the 1970s with the rise of the Black Panther Party in the United States of America. Marvel Comics made Black Panther the Black Leopard for a handful of months in 1972, in an effort to avoid confusion that he was associated with the Black Panther Party. However, the publisher eventually changed the name back realizing doing so to begin with was a mistake.
Black Panther was one of the first Black Superheroes to star in a mainstream book. Co-created by Jack Kirby and Stan Lee, T’Challa first appeared in Fantastic Four #52. Over time, Black Panther has become a key part of the Avengers and one of the most beloved Marvel heroes in existence. The hero was adapted to the big screen in Captain America: Civil War and starred in his own self-titled solo film. In the Marvel Cinematic Universe, the hero was played by the late Chadwick Boseman.
