Nightwing is a superhero legacy name associated with the planet Krypton and the Batman Family, usually working alongside a sidekick and partner named Flamebird. Originally it was an alias used by a mysterious Kryptonian figure, and later adopted by Superman and Van-Zee in the bottle city of Kandor. Later the name was adopted by the human vigilante Dick Grayson, taking it after he had graduated from the position of Batman's sidekick Robin. It is currently held by Chris Kent, General Zod's son living on New Krypton.
