Richard Grayson (Earth-2899)

Richard "Dick" Grayson is the son of a famous couple of acrobats who travelled the United States showing their feats to everyone. While on a tour to Gotham City, New Jersey, Dick's parents were killed by mob boss Black Mask after their circus' owner refused to pay the gangster and his False Facers a tribute. Left orphaned, he was taken upon by Bruce Wayne, who adopted him and made him a vigilante just like himafter Grayson discovered his secret identity as Batman. Calling himself Robin, they had a famous career across the city until Dick decided he wanted to live his own adventures and moved to Bludhaven, New York, where he adopted the persona of Nightwing and started a career against crime on his own and often alongside other vigilantes such as Spider-Man, Daredevil, Luke Cage and Jessica Jones.
