No clue. He was made up purely for the excitment and drama of the show. But some people think its Jason Todd, the dead Robin(the joker killed him). They think this because when Robin is red x, and BB is trying to explain that its not Robin, he makes a chart. On it is a monkey robin, a robot robin, larry, and A robin labled Jason Todd(i might be wrong about some of the stuff on the bored and the episode, but every thing else im positive of).
