a solo series focusing on Dick's exploits as an agent of Spyral. The series lasted until June 2016 and was succeeded by a new Nightwing series with DC Rebirth. DC Rebirth Following the erasure of the knowledge regarding his secret identity from most of the world in the final issue of Grayson Dick went back to the Nightwing identity in the DC Rebirth era solo series, and the costume's colors were changed back to the traditional black and blue. At the start of the series (rebirth) Nightwing is still a member of the Court of Owls (after Robin War) and he goes on missions around the world for the Court. They give him a partner named "Raptor" and like Nightwing he wears a costume, but he is much more violent than Dick and multiple times Dick has to try to stop him from killing. Throughout the story arc, Dick must work as an undercover agent but also has to keep his morals and not kill even if the Court tells him to. Later on in the series, an event causes him to lose his memory, which leads him to the name change of Ric Grayson and temporary retirement of the Nightwing alias. Infinite Frontier In March 2021, the series became part of DC's new relaunch Infinite Frontier. Tom Taylor became the new writer with Bruno Redondo as the artist. The series follows Dick Grayson's return to Blüdhaven as he fights crime while grappling with newfound responsibility from inheriting billions in wealth from Alfred Pennyworth. Dick begins to mentor Jon Kent and decides to use the money to launch a nonprofit organization named after Alfred to support the people of Blüdhaven, which puts him into conflict with Blockbuster and Heartless, a mysterious serial killer preying on the homeless. Dick also meets Melinda Zucco, his long lost half-sister who becomes Blüdhaven's mayor.
