Nightwing

Richard "Dick" Grayson, known as the first Boy Wonder (Robin). Adopted by Bruce Wayne (Batman) after the tragic deaths of John and Mary Grayson at the Flying Graysons' show. From there, Batman trained the young man his ways to become the sidekick of the vigilante. Things changed after a controversial between the two, as Grayson abandoned Bruce to become Nightwing. Still being Batman's consistent partner, he patrols Bludhaven.
