Nightwing

From Thebatwiki

Nightwing (Dick Grayson) is a circus acrobat WHOSE PARENTS ARE DEAD. He was Batman's first robin, and then graduated to being the leader of the Teen titans, and briefly a member of the Outsiders. He has inheirited some part of Batman's gift for outthinking and outfighting ridiculously overpowered opponents. Fanon for the character states that he is probably the best-endowed of the male batfamily, as evidenced by the fact that he can satisfy Starfire.
