Nightwing is a fictional superhero appearing in American comic books published by DC Comics. The character has appeared in various incarnations, with the Nightwing identity most prominently being adopted by Dick Grayson when he moved on from his role as Batman 's vigilante partner Robin.
Although Nightwing is commonly associated with Batman, the title and concept have origins in classic Superman stories. The original Nightwing in DC Comics was an identity assumed by alien superhero Superman when stranded on the Kryptonian city of Kandor with his pal Jimmy Olsen. Drawing inspiration from Batman and Robin, the two protect Kandor as the superheroes Nightwing and Flamebird. Following the Crisis on Infinite Earths continuity reboot in 1985, Nightwing was re-imagined as a legendary vigilante from Krypton whose story inspires Dick Grayson 's choice of name when he leaves behind his Robin identity.
Other stories set among the Batman family of characters have seen acquaintances and friends of Dick Grayson briefly assume the title, including his fellow Robin alumnus Jason Todd. Meanwhile, Superman stories have seen Power Girl and Superman 's adopted son Chris Kent take up the name for brief turns as Nightwing. Various other characters have taken the name in stories set outside DC's main continuity as well, and at times the role has been unoccupied, such as when Dick Grayson operated as Batman and after faking his death.
