Biography[]
Robin was out to stop crime until he was kidnapped by The Joker & Harley. Robin was mentally and physically tortured by The Joker, who attempted to make him into his own image. It became too much for Robin so he began to reveal secrets about Batman to Joker. Now his skin was chalk white, and his face was permanently changed into a giant grin, Robin was now called "J.J.". Joker asked J.J. to "deliver the punch line" and kill Batman. Resisting Joker's orders he instead shot the BANG gun right through Joker's heart. He was traumatized of what he saw that night he saw a psychiatrist, Dr. Leslie Thompkins until he was back to himself. Bruce forbade him to be Robin after that night, so he left Bruce to become his own man.
