The original Robin, Richard "Dick" Grayson grew up and left Gotham. Wanting to be treated as an equal by Batman rather than just his sidekick, he not only told off Bruce but left for awhile and, when he returned to Gotham, he adopted the new codename of 'Nightwing. However, he left Gotham again after reconciling with Bruce and aiding Tim Drake (the third Robin), and relocated to Bludhaven where he combats the crooks that are too dangerous for the cops.
