(Action Comics 027, 1940)
What makes them a super-villain? It's 100% the name plus the fact that "air pirate" along with "submarine pirate" and for that matter "regular pirate" are styles of crime that just reek of super-villainy for me.
What about them is interesting? Aside from the inherent romantic nature of the air pirate, the only real thing of note about the Blue Raider is that his plane is named Hank.
