It’s well known that the first comic with a black main character was Dell’s western character Lobo in 1965, and that the first black superhero was the Black Panther and first African American hero in the comic was The Falcon.
In 1949 Fawcett Comics released Jackie Robinson Baseball Hero which ran for six issues until 1953. Yeah you say, but that was “non-fiction” right, or at least a comic book version of non-fiction.
Yes, it was based on the real life experiences of Jackie Robinson; however each of the six issues also featured Robinson in a purely fictional story, such as Jackie Robinson and the Teen-Age Terror or Jackie Robinson and The Human Cat.
So wouldn’t that make him the both the first American comic with an African American main character?
