Red Bird is Jason Todd. Another deviation from the history of the normal universe is that Jason Todd didn't die by the Joker's hand. He moved on and became his own hero. He stopped dying his hair black (it seems DC forgot that he was originally blond) and roamed the world studying different disciplines of martial arts after retiring as Robin. The day the Justice Lords emerged he confronted Batman about how this was against everything he ever taught him, but Batman wouldn't listen. This caused a falling out between them. Back before he left Bruce gave him a generous amount of money to start his life on his own. Not really needing all of it he invested it wisely. Upon returning from his trek around the world he had a fortune, mind you not as vast as Wayne's but enough he could have lived a normal life and never worked. He invested this into the Justice Rebels and as Jason Todd (he is the only rebel that the Lords don't know his secret identity. I guess Batman may have heard more than Jason thought for not giving up his name to them) he continues to acquire money though other investments to fund there war effort. After Batman's defection to the rebels he and Jason had a heart to heart talk. They are now a dynamic duo against the Justice Lords.
