"Titans Reunited"
In 1996, following the success of the miniseries, DC Comics launched a monthly solo series featuring Nightwing (written by Chuck Dixon, with art by Scott McDaniel), in which he patrols Gotham City's neighboring municipality of Blüdhaven.
Upon the request of Batman, Dick journeys to the city of Blüdhaven to stop the gangster Black Mask. He then becomes the arch-enemy of the villain Blockbuster. Dick decides to stay in Blüdhaven until he destroys Blockbuster's drug cartel. After Cyborg is put in danger by a galactic threat, Dick reunites the Teen Titans[1] to rescue him. They reform as the Titans, but Dick is pulled away to Gotham City when it is declared a No Man's Land. Following the recuperation of Gotham, Dick stays active as both the leader of the Titans and stays in Blüdhaven.
Following the deaths of Lilith Clay and Troia, Dick officially disbands the Teen Titans. Dick then returns to Blüdhaven and becomes more and more like Bruce, straining his relationships and eventually blurring the line between being a police officer and a vigilante.[2] The vigilante Tarantula then kills the Blockbuster, who Dick fails to save. Blockbuster's death haunts him to the point of temporarily retiring from crime-fighting.[2][3] At length, Nightwing shakes himself from his depression and takes responsibility for his inaction.
Infinite Crisis and The New 52
Due to a crisis of conscience, Dick adopts the new villainous persona of Renegade in order to infiltrate Lex Luthor's (Alexander Luthor Jr. in disguise) Secret Society of Super Villains. This ruse includes Nightwing aligning himself with his long-time enemy Deathstroke in order to track the manufacturing and distribution of Bane's Venom serum and to keep tabs on the Society's activities in Gotham and Blüdhaven. He also begins training (and subtly converting) Deathstroke's daughter Rose Wilson.
Deathstroke takes revenge on Nightwing after Blüdhaven's destruction. The Society drops the supervillain Chemo onto the city, killing 100,000 people. Dick tries to rescue survivors, but faced with radiation poisoning. He is then rescued by Batman, when Nightwing asks forgiveness from Batman about Blockbuster's death, Batman persuades Dick to finally move beyond. Inspired by his mentor, he then proposes to Barbara Gordon, who tearfully accepts.[4][5]
Batman then entrusts Nightwing to alert other heroes about the danger that the Crisis poses. Dick flies to Titans Tower, but due to the chaos resulting from the Blüdhaven disaster, the
"One Year Later"
One year later, Dick Grayson returns to New York City (his previous home base with the Teen Titans) in order to find out who has been masquerading as Nightwing. The murderous impostor turns out to be the former Robin, Jason Todd. Grayson leads the Outsiders once again, operating undercover and globally.
Nightwing follows an armored thief named Raptor, whom he suspects is responsible for a series of murders. Later, Raptor himself is murdered in a manner similar to the other victims by an unseen contract killer, who proceeds to bury Grayson alive. Nightwing frees himself, wondering the relation between his experience and a mysterious voice who tells him that he is "supposed to be dead". Nightwing is having trouble finding things to keep him busy during the day due to the cast on his right arm. Incapacitated from his injuries, he tries without luck to find jobs, which forces him to take a job as a low-paid acrobatic instructor at a local gym, and continues to research into the mysterious assassin.
At one point, Dick agrees to attend a party for Bruce and their relationship seems to flourish. Bruce praises Dick for his success on the Raptor case, and also mentions to look into the Landman Building which hosted ex-Lexcorp scientists; most likely those who worked on the Raptor project. Dick also continues to keep a close brotherly relationship with Tim Drake, and helps Tim deal with his many losses during the last year.
After dealing with the Raptor issue, NYC is plagued by a villainous duo called Bride and Groom. Nightwing begins pursuit of these two after some grisly murders, including that of the Lorens family (close friends of his after the Raptor incident). Dick began to get obsessed with finding them, not knowing how far he was willing to go to take them down. Eventually, he formed a makeshift team with some "villains" to find them.
"Titans Return"
Nightwing joins a new team of Titans, with the same roster of the New Teen Titans,[10] to stop an as-yet unnamed offspring of Trigon from enacting his vengeance over Raven and the Titans of every generation. Nightwing yet again leads the team, and they manage to stop the sons of Trigon from accomplishing their first attempt at global destruction and again a few days later.
Following the defeat of Trigon's sons, the Titans are approached by Jericho, who had been stuck inhabiting the body of Match, Superboy's clone. The Titans managed to free Jericho, but found themselves once again in trouble, because Jericho's mind had become splintered due to all the bodies he had possessed in the past. Torn between evil and good, Jericho possesses Nightwing's body in order to keep from being captured. During this time, Jericho forces Nightwing to relive all of his greatest pains. Soon afterward the JLA arrived, intent on taking Jericho in, but they fail to apprehend him.[11]
Following this, Nightwing decides to leave the team again, due to the events of the "Batman R.I.P." storyline and Batman's apparent death, as Nightwing feels his attention is better aimed at protecting Gotham City.
