Bio: Kelly was a thirteen year old schoolgirl and scout whom Batman saved from muggers on the night of his return from retirement. She then spent her lunch money on a Robin outfit and set out to attack petty con-men and to find Batman. Kelly used a slingshot and firecrackers as weapons. She also wore green-tinted sunglasses.
Batman accepted her as Robin when she saved his life just as he was on the verge of being killed by an enemy. He often threatened to fire her but she showed considerable ability and improvisation which impressed him enough to give her a stay of dismissal even when she disobeyed his orders.
Notes: Carrie was Robin in The Dark Knight Returns, and later became Catgirl
