Dick Grayson, once a member of the acrobatic Flying Graysons, was taken in by Bruce Wayne, who was secretly the vigilante Batman, as his legal ward after witnessing his parents' tragic deaths. Under Batman's guidance, Dick trained rigorously, combining his natural acrobatic abilities with the Dark Knight's expertise in combat and detective work.
He became the first Robin, fighting alongside Batman to bring justice to Gotham. As he matured and sought his own identity, Dick eventually adopted the mantle of Nightwing, stepping out of Batman's shadow to fight for justice on his own terms.
