Nightwing

Nightwing is a codename used by multiple characters appearing in American comic books published by DC Comics. Since its debut in Superman #158 (January 1963), the codename has been tied to both Superman and Batman comic book titles and characters. Originally, the usage of the codename originated from Superman acting as a vigilante in Kandor, naming himself after an alien bird species from Krypton. The name would also become associated with a relative of Superman in Kandor, Van-Zee. Paralleling Batman and Robin, Nightwing is commonly associated with a sidekick, Flamebird. Since Tales of the Teen Titans #44 (1984), the name has instead been primarily associated with Dick Grayson; when asserting his independence from Batman as a superhero and a young adult, the character is told the story of a legendary Kryptonian vigilante by Superman who was similarly disowned but used his talents to help others. Inspired by the story, Grayson adopts the codename for himself. The name is also adopted by Chris Kent (also known as Lor-Zod) in association with a protector god Nightwing created by chief god Rao. Several other characters also utilize the name alternately, including Power Girl in a Kandor-related storyline and Jason Todd in one storyline impersonating Grayson. Other versions of Nightwing have also appeared in non-canonical and alternate universe stories, including in other media. As Nightwing, in 2013, Dick Grayson's version placed 5th on IGN's Top 25 Heroes of DC Comics and Grayson as Nightwing was ranked the #1 Sexiest Male Character in Comics by ComicsAlliance in 2013.
