ALTER EGO: DICK GRAYSON
Dick Grayson was the original Robin until he and Batman disagreed on crime fighting techinques. Dick decided it was time to give up the persona of Robin and move on with his life. He didn't want to quit crime fighting altogether, however, and became a member of the Teenage Titans. At one point he became the leader of the Teenage Titans. Eventually he left the Titans and went out on his own as Nightwing. He does occasionally help out Batman and Robin when they need it.
