Nightwing
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.
Marv Wolfman
In 2006, Wolfman was editorial director of Impact Comics (no relation to the DC Comics imprint), publisher of educational manga-style comics for high school students. That same year, starting with issue No. 125, Wolfman began writing DC's "Nightwing" series. Initially scheduled for a four-issue run, Wolfman's run was expanded to 13 issues, and finished with No. 137. During the course of his run, Wolfman introduced a new Vigilante character. Following Wolfman's departure from the pages of "Nightwing", the Vigilante was spun off into his own short-lived title, which Wolfman wrote. He wrote a miniseries starring the Teen Titan Raven, a character he and George Pérez co-created during their run on "The New Teen Titans", helping to revamp and update the character. He is working with Pérez on a direct-to-DVD movie adaptation of the popular "Judas Contract" storyline from their tenure on "Teen Titans". In 2011, he and Pérez completed the "" graphic novel, which they had begun working on in the late 1980s. Wolfman revived his "Night Force" series with artist Tom Mandrake in 2012.
