In the comic, Blackstone traveled the world, performing amazing feats of magic and battling exotic villains. In issue #5, Blackstone rescues a young woman named Rhoda from pirates, and she becomes his regular sidekick. Blackstone appeared in the comic published monthly until February 1946 (Vol. 4, issue #10). The following month, he was replaced by another lead character, "Elliman, Ace of Magic".
