(Action Comics 028, 1940)
AKA the Leopard Skin Thief AKA the Strongarm Bandit - this is our first example of a clear super-villainous character who has not bothered to give themself a name and so we must take one from the text boxes or (as in this case) from the names given to them by the other characters.
Mr Leopard Skin is fun because he is obviously dressed as a circus strongman, and that is because his crime career is an attempt to frame a circus strongman. The actual culprit, the circus clown, has to basically be caught before anyone else at the circus thinks to mention that the clown used to be the old strongman before a stronger strongman showed up and he got demoted and maybe might want revenge.
