The New Nightwing

 
In the aftermath of Battle of The Cowl, Dick Grayson is no longer Nightwing. However, that doesn't mean that superhero name is gone. A different hero, also called Nightwing, appeared in the pages of Action Comics, paired with a female hero named Flamebird. This Nightwing is Kryptonian Christopher Kent.
