Detective Comics #222 (1955)

THE GREAT BATMAN SWINLE! Ned Judson, a wealthy yachtsman, is called to a mysterious castle once built by an eccentric millionaire, and comes face-to-face with the Brotherhood of Batmen. The leader, Batman Number One, convinces Judson that the figure of Batman is actually four people, and, because of the death of one of their members, he is to become Batman Number Four. Judson agrees and joins the Brotherhood, not knowing that all the members are actually criminals who want to take advantage of Judson's admiration for Batman. The crooks "train" Judson and allow him to "capture" some criminals to make their charade believable. A short time later, the crooks start asking for money from Judson in order to provide him with his own Bat-Vehicles and equipment, which of course is a fraud to steal his money. Soon, the real Batman and Robin learn of the situation and they decide to help Judson realize the trap he has fallen for. The Dynamic Duo train Judson and after an extensive regime, the trio capture the Brotherhood of Batmen. Judson, finally learning of his mistake, is happy that he got to work with the real Batman. THE OCEAN PEST! THE MAN WHO SLEPT 200 YEARS!
