Robin: All hail the boy wonder

Batman and Socko doesn’t quite have the same ring, but Socko was one of many names Batman creators Bill Finger and Bob Kane debated with artist Jerry Robinson when they decided Batman — a smash hit since his 1939 debut — needed an assistant. Amazingly, no superhero before had had a teenage sidekick.
Mercury, Wildcat, Pepper and Davy (as in Crockett) were suggested until Robinson had a brainwave: “I thought of a young Robin Hood and suggested adapting his costume for the new character. I added the final touch, the small R on his vest.”
