Detective Comics #317

THE SECRET OF THE FLYING BAT-CAVE Batman and Robin bring the Flying Bat-Cave to Center City for a police convention and help a rookie cop nab a national crime syndicate, the Condor Gang. THE CHALLENGE OF THE ALIEN ROBOTS Four alien robots land in a capsule on Earth, complete with full operating instructions. They are discovered by Jasper Dowd, a criminal, who uses the automaton's mighty powers to help him pull off spectacular robberies. J'onn J'onzz battles the robots, but is stymied by their gas, lightning, and fire powers, and by their ability to teleport away when Dowd wishes. Diane Meade tracks down Dowd, but is captured by his robots. However, the Manhunter destroys one robot, assumes its guise, and trails the other robots back to Dowd's hideout. There he smashes the other robots, saves Diane, and captures Dowd.
