Question: Who is Nightwing?

Nightwing




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  Superman's adopted son Chris Kent and Power Girl 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.
Nightwing  book. In 2013, Nightwing placed 5th on IGN's Top 25 Heroes of DC Comics[2] and Grayson as Nightwing was ranked the #1 Sexiest Male Character in Comics by ComicsAlliance in 2013.[3]
Fictional character biography
Pre-Crisis Era
Superman

Nightwing is first depicted in the story "Superman in Kandor" in Superman #158 (January 1963). It is an alias used by Superman in pre-Crisis stories. The story is set in Kandor, a Kryptonian city that was shrunken and preserved in a bottle by Brainiac. In Kandor, Superman has no superpowers, and is branded an outlaw there due to a misunderstanding.
To disguise themselves, Superman and Jimmy Olsen create vigilante identities inspired by Batman and Robin. Because neither bats nor robins lived on Krypton, Superman chooses the names of two birds owned by his Kandorian friend Nor-Kan: Nightwing for himself, and Flamebird for Jimmy. Nightwing and Flamebird rename Nor-Kan's underground laboratory as the "Nightcave", and use it as their secret headquarters. They also convert Nor-Kan's automobile into their "Nightmobile", and use "jet-belts" to fly into battle.
In Jimmy Olsen #69 (June 1963), "The Dynamic Duo of Kandor" introduces Nightwing's dog Nighthound. In "The Feud Between Batman and Superman" in World's Finest #143 (August 1964), Batman and Robin themselves visit Kandor with Superman and Olsen and the two Dynamic Duos team up.
Van-Zee
In Superman Family #183 (May/June 1977), Superman's look-alike second cousin Van-Zee and his niece's husband Ak-Var take up the Nightwing and Flamebird identities. The vigilantes take on crime in their city as had Superman and Olsen before them.

Dick Grayson
Both Nightwing and Flamebird team up with Batman and Robin for an adventure in Kandor that proves important to the young Dick Grayson. When Dick later gives up his role as Robin in 1984, he recalls the Kandorian adventure and renames himself Nightwing, in homage to both Batman and Superman.[4] After the events of the Crisis on Infinite Earths re-boot of the DC Universe, Superman no longer has knowledge of Kandor; instead, he remembers Nightwing as an urban legend of Krypton, which he shares with a young Dick Grayson.
Post-Crisis
Kryptonian mythological figure
Post-Crisis, there is a different originator of the Nightwing identity. Several hundred years before the birth of Kal-El, there was a Kryptonian man who was cast out from his family and decided to take on crime as the vigilante Nightwing.[5] When Superman tells Dick Grayson of this story, Dick takes the name for himself.
Dick Grayson


Dick Grayson became Nightwing after he was dismissed from the role of Robin as a teenager. Grayson's Flamebird was Bette Kane. He was featured in a Nightwing series from 1995 to 2009; after Wayne's apparent death, Grayson became the new Batman, subsequently retiring his Nightwing mantle temporarily.
Grayson's Nightwing costume was a high-tech suit specially designed for his high-flying acrobatic style. His gauntlets and boots each contained eight compartments in which he could store items. They had a self-destruct feature built into them, similar to the ones in Batman's utility belt, and, as another security measure, the suit contained a one-use-only taser charge, which automatically emitted a high-voltage electrical shock when someone attempted to tamper with either the boots or gauntlets.
Each gauntlet's sections could contain a wide array of equipment, such as sonic or smoke pellets, modified batarangs ("Wing-Dings"), knockout gas capsules, throwable tracers, and a sedative-tipped dart launcher. The right gauntlet was also equipped with a 100,000-volt stun gun. Like the gauntlets, his boot compartments could carry vital equipment such as flares, a rebreather as protection against any airborne non-contact toxins, a mini-computer equipped with fax, modem, GPS, and a minidisk re-writable drive. Other items were lock picks, a first-aid kit, a mini-cellphone, flexi-cuffs, antitoxin assortment, wireless listening devices, and a small flashlight. After coming to New York, Dick added a black utility belt to his costume, eliminating the need for his boots and gauntlets.
Held in spring-loaded pouches in the back of his costume, Dick carried a pair of eskrima clubs made from an unbreakable polymer that were wielded as both offensive and defensive weapons. Some depictions display these tools with the mechanism to shoot a grappling hook attached to a swing line, while, in other instances, they can act as "line guns" similar to the ones Batman uses. The clubs could also be thrown with such skill by Grayson (and possibly due to their design) that they would ricochet off walls and objects to hit multiple targets, then return to his hands.  These clubs also have the capability to be linked together as well as grow in size to make a staff, as depicted in many series, such as Teen Titans and Young Justice (Robin uses these weapons).
Superman
In 2001's Superman: The Man of Steel #111, Superman and Lois Lane travel to a version of Krypton later revealed to have been created by the villainous Brainiac 13 and based on Jor-El's favorite period in Kryptonian history.[6] Labeled as criminals, Superman and Lois become fugitives, adopting the Nightwing and Flamebird identities to survive, just as had Superman and Olsen in Superman #158.[7]
Tad Ryerstad
In Blüdhaven, a sociopath named Tad Ryerstad becomes a superhero, inspired by the retired hero Tarantula. He takes his name, "Nite-Wing", from an all-night deli specializing in chicken wings. Unstable, Nite-Wing beats people for minor offenses. Nite-Wing is shot on his first night out and Dick Grayson, as Blüdhaven's protector Nightwing, defends him from Blockbuster's gang, who think it is Nightwing who has been injured. After Nite-Wing is released from the hospital, he kills the gang who put him there. Not realizing how violent Ryerstad is, Grayson agrees to train him. The two attack Blockbuster's organization, but are captured and separated. After an undercover FBI agent frees Nite-Wing, Ryerstad beats him to death, and when he realizes what he has done, Ryerstad flees.[8] Nightwing subsequently tracks down and incarcerates Nite-Wing.[9] In prison, Ryerstad is cell-mates with Torque (Dudley Soames), but the two escape by drugging the prison guard Amygdala.
Jason Todd

Nightwing #118-122[10] run features Jason Todd prowling the streets of New York City under the guise of Nightwing, copying Grayson's costume.
Cheyenne Freemont
The "One Year Later" storyline features a metahuman fashion designer named Cheyenne Freemont donning a modified Nightwing costume to help Grayson.[11]
Cheyenne first met Dick when they had a one-night stand together. They only exchanged first names the next morning, Cheyenne stating she's superstitious. The two had breakfast together and then he left. When he left another man walked into her apartment. He assaulted her for getting her "plumbing" fixed in her bath robe. She hit him with a telekinetic blast.
Dick found out Cheyenne was a fashion designer from a friend of his from Bludhaven. She ran into Dick again after he accidentally became a model for her. After seeing newspaper clippings of Nightwing (Jason Todd) she started creating superhero themed designs. Cheyenne wore a Nightwing costume to help Dick and Jason from a metahuman monster named Jakob. He ate her, but she used her powers to blow him up from the inside. Due to recent events she was left broke and soon left New York City.[12]

Power Girl
In Supergirl #6, Power Girl and Supergirl assume the identities of Nightwing and Flamebird in a story set in Kandor, just as in the original pre-Crisis stories featuring Superman.
Chris Kent

Chris Kent, son of General Zod, was Nightwing during Superman: New Krypton. In that storyline, Superman was coming to terms with the death of his adoptive father; he was also dealing with 100,000 Kryptonians now living on Earth, which he had released from the bottled cities on Brainiac's ship (the same ship that contained the lost Kryptonian city of Kandor). At the end of the fourth issue of the arc, a new Nightwing and Flamebird appear in Superman's Fortress of Solitude to stop two of Zod's followers (who were living in Kandor) from releasing the Kryptonian General from his Phantom Zone imprisonment. While guarding the projector in order to prevent any Zod loyalists from freeing him from the Phantom Zone, both Flamebird and Nightwing exhibit powers that are not inherent to normal Kryptonians. Flamebird projects flames from her hands, and Nightwing uses "natural tactile telekinesis".
The pair seems to be stronger than normal Kryptonians: they knock out the two Zod loyalists with one blow apiece. In a later appearance, the duo is seen in Gotham City. Unlike previous portrayals, it seems Flamebird believes herself to be the dominant partner. When the Kryptonians led by Zod and Alura flee to a new Krypton orbiting the Sun, Nightwing and Flamebird stay in Gotham. In Action Comics #875, that Nightwing is revealed as the son of Zod and Ursa, Chris Kent. The "Nightwing" identity is revealed to be based on a mythical Kryptonian creature, whose existence is intertwined with that of its partner beast, the Flamebird. Inside the Phantom Zone Chris' mind interfaced with a piece of Brainiac technology, awakening a long-dormant connection to the Nightwing, and linking his mind to that of Thara Ak-Var, who had a connection to the Flamebird.[13]
Other uses in comic books
In the DC Comics Tangent Comics series, "Nightwing" is a secret government organization which appears throughout the series. Headed by Marcus Moore and Francis "Black Lightning" Powell, who act to protect the U.S.A. and also conceal the true nature of The Atom's involvement in the Cuban Missile Crisis.
Terry McGinnis briefly moonlights as Nightwing in Batman Beyond #4, after Detective Ben Singleton claims to know Dick Grayson's past as Nightwing, which turns into a media fiasco.
Ongoing series
Story arcs

Based on Nightwing's increasing popularity, DC Comics decided to test the character's possibilities with a one-shot book and then a miniseries.
First, in Nightwing: Alfred's Return #1 (1995), Grayson travels to England to find Alfred, who resigns from Bruce Wayne's service following the events of KnightSaga. Before returning to Gotham City together, they prevent a plot by British terrorists to destroy the undersea "Channel Tunnel" in the English Channel.
Later on, with the Nightwing miniseries (September 1995 to December 1995, written by Dennis O'Neil with Greg Land as artist), Dick briefly considers retiring from being Nightwing forever before family papers uncovered by Alfred reveal a possible link between the murder of the Flying Graysons and the Crown Prince of Kravia. Journeying to Kravia, Nightwing (in his third costume) helps to topple the murderous Kravian leader and prevent an ethnic cleansing, while learning his parents' true connection to the Prince.
Blüdhaven
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's neighboring municipality of Blüdhaven.
At Batman's request, Dick journeys to this former whaling town-turned-industrial center to investigate a number of murders linked to Gotham City gangster Black Mask. Instead, he finds a city racked by police corruption and in the grips of organized crime consolidated by Roland Desmond, the gargantuan genius Blockbuster.
With a defenseless city to call his own, Nightwing decides to remain in Blüdhaven until Blockbuster's cartel is broken. This allows him to be close enough to Gotham to still be part of the Batman family, and far enough as well to have his own city, adventures and enemies. He takes a job as a bartender to keep his ear to the ground and worked closely with Oracle (Barbara Gordon) in an effort to clean up the town. Blockbuster places a sizable contract on Nightwing's head shortly thereafter, while Grayson plies the unscrupulous Blüdhaven Police Inspector Dudley Soames for information on the kingpin's dealings. Also during his time in Blüdhaven, Nightwing helps train a violent but enthusiastic street fighter called Nite-wing, who later kills an undercover FBI agent.
Last Laugh and killing the Joker
When the Joker is told he is dying by his doctor, he unleashes Joker juice on the inmates at the Slab, causing a breakout. At the end of the arc, Nightwing is responsible for killing the Joker against the wishes of Batman and Oracle. Nightwing becomes depressed and Oracle tries to bring him out of it.[14] Soon after, Batman manages to revive the Joker.
Leader of the League
Sometime after "No Man's Land" ends, the JLA disappears on a mission to locate Aquaman and Atlantis (The Obsidian Age). Before they vanish, Batman instigates a contingency plan, in which a handful of heroes would be assembled to create a new JLA, consisting of Nightwing, Green Arrow, the Atom, Hawkgirl, Major Disaster, Faith, Firestorm and Jason Blood. Nightwing is chosen to be leader until the original JLA are found, leading the group against the powerful Atlantean sorceress Gamemnae and helping to revive Aquaman to ask for his help in sinking Atlantis, but subsequently returns to the reserve list.
Graduation Day
For several years, Nightwing leads various incarnations of the Titans and becomes the most respected former sidekick in the DC Universe. However, in the Titans/Young Justice: Graduation Day crossover, a rogue Superman android kills Lilith and Troia, an event that tears apart both Young Justice and the Titans. At Troia's funeral, Dick declares he is tired of seeing friends die and disbands the team, officially ending the Titans. A few months later, Arsenal persuades Nightwing to join a new pro-active crime-fighting team: the Outsiders, who would hunt villains, acting as co-workers rather than an extended family. He reluctantly accepts.
Death of Blockbuster
Dick plays a key role in exposing the corruption in the Blüdhaven Police Department. Despite reaching his original goals, Dick continues as a police officer during the day while spending nights as Nightwing, pushing himself to his limits and straining his relationships. The line between his police work and his vigilantism began to blur, and ultimately Amy Rohrbach (his friend and superior officer, who knew his secret identity) fires him rather than let him continue using questionable methods.
Wrongfully blaming Nightwing for the death of his mother, the mob boss Blockbuster bombs Dick Grayson's apartment complex and promises to kill anyone in Dick's life. When the vigilante Tarantula arrives, Nightwing chooses not to stop her when she shoots the villain dead.[15] He enters in a catatonic state after this action, and Tarantula takes advantage of his emotional trauma to rape him. At length, Nightwing shakes himself from his depression and takes responsibility for his inaction. He captures Tarantula and turns her and himself in to the police. Amy, however, feels the world needs Nightwing free and so prevents him from being charged.
Though, Dick has destroyed the police corruption and removed the greater part of organized crime from this city, but his role in Blockbuster's death is still a source of tremendous guilt for him. He retires from crime fighting, with Tim Drake and Cassandra Cain as his replacements.
Grayson moves to New York, where he works closely with the Outsiders. After "insiders" threaten both the Outsiders and the newest incarnation of Teen Titans, however, Nightwing realizes that the team has gotten "too personal" and quits.
Infinite Crisis and 52
Due to a crisis of conscience, Dick adopts the new villainous persona of Renegade in order to infiltrate Lex Luthor's 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, Ravager.
Deathstroke takes revenge on Nightwing when Blüdhaven is destroyed by the Society. The Society drops the super villain Chemo on the city, killing 100,000 people. Dick tries to rescue survivors but is overcome by radiation poisoning; only to be rescued himself by Batman. Nightwing confides that he let Blockbuster die and asks Batman to forgive him. Batman tells him that his forgiveness doesn't matter; Dick has to move beyond Blockbuster's death. Inspired by his mentor, he proposes to Barbara Gordon, who accepts his proposal with a kiss.
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 OMAC onslaught and other Crisis related events, the only hero who answers his call is Conner Kent. Together, they locate and attack Alexander Luthor's tower, the center of the Crisis, only to be repelled by Superboy-Prime. Prime is ready to kill Nightwing when Conner intervenes, sacrificing himself to destroy the tower, ending the destruction of the Universe.
During the Battle of Metropolis, Nightwing suffers a near-fatal injury from Alexander Luthor when he attempts to save Batman's life. Originally, the editors at DC intended to have Dick Grayson killed in Infinite Crisis as Newsarama revealed from the DC Panel at WizardWorld Philiadelphia:[16]




“It was again explained that Nightwing was originally intended to die in Infinite Crisis, and that you can see the arc that was supposed to end with his tragic death in the series. After long discussions, the death edict was finally reversed, but the decision was made that, if they were going to be keeping him, he would have to be changed. The next arc of the ongoing series will further explain the changes, it was said.”
Saved by the Justice Society, Nightwing recovers with Barbara at his side. As soon as he's able to walk again, Batman asks him to join him and Robin in retracing Bruce's original journey in becoming the Dark Knight. While Nightwing is hesitant, due to his engagement with Barbara, she encourages him to go and returns his engagement ring so he can make an honest decision for himself. Barbara feels that it is important he rediscover himself, and until he does they're not yet ready to be married. They part on good terms, though before he departs Dick leaves her an envelope containing a photograph of them as Robin and Batgirl, along with the engagement ring on a chain and a note promising he'll come back to her one day.[17]
Soon after his journey with Batman and Robin ends, Nightwing returns to Gotham, following Intergang's trail. He works with the new Batwoman and Renee Montoya to stop Intergang from destroying Gotham, shutting off dozens of fire-spewing devices spread across the city.
"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 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 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. They located them, and after killing some of his "team", Nightwing chased them to a cave, where Bride began a cave-in and the two are trapped there.
Nightwing, along with a group of former Titans, are summoned again by Raven to aid the current group of Teen Titans battle against Deathstroke, who was targeting the latest team in order to get at his children, Ravager and the resurrected Jericho. Nightwing and the other former Titans continue to work with the current team soon after the battle with Deathstroke so as to investigate the recent murder of Duela Dent.
When the Outsiders were targeted by Checkmate, Nightwing agrees that his team will work with the organization, so long as their actions in Africa are not used against them in the future. The mission however does not go as well as intended, resulting in Nightwing, the Black Queen and Captain Boomerang being captured by Chang Tzu. Later, Batman is called in by Mister Terrific who then rescues Nightwing and the others. Afterwards, Nightwing admits to Batman, that while he accepts that he is an excellent leader, he is not suited to lead a team like the Outsiders, and offers the leadership position to Batman.
Batman accepts the position; however, he feels that the team needs to be remade, in order to accomplish the sorts of missions that he intends them to undertake. As such, he holds a series of tryouts for the team. The first audition involves Nightwing and Captain Boomerang who are sent to a space station under attack by Chemo. During the mission, a confrontation erupts between Nightwing and Boomerang, who has grown tired of fighting for redemption from people like Batman and Nightwing. After taking a beating from Nightwing, he manages to throw him into a shuttle heading for Earth and quits the team. Afterwards, Nightwing furiously confronts Batman. Batman does not deny his actions, and states that this is the sort of thing that the new Outsiders will have to deal with. At this, Nightwing resigns completely from the Outsiders, which Batman feels is best, judging Nightwing too good for that sort of life.
In order to help himself regain a sense of purpose, Nightwing opted to stay in New York City again, and play the role of the city's protector. He takes on a job as a museum curator; and uses the museum as his new base of operations. During his short time there, Dick finds himself once again confronted with Two-Face, who years ago delivered Dick's greatest defeat. This time however, Dick soundly defeats Two-Face.
"Titans Return"
Nightwing joins a new team of Titans, with the same roster of the New Teen Titans, to stop an offspring of Trigon, which has not yet been named, 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, due to the fact the 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 after, the JLA arrived, intent on taking Jericho in. Unfortunately they fail to apprehend him.
Following this, Nightwing decides to leave the team again, due to the events of the "Batman R.I.P." storyline, and due to Batman's apparent death, Nightwing feels his attention should be better aimed at protecting Gotham City.

"Batman R.I.P" and "Battle for the Cowl"
As a precursor to "Batman R.I.P.", at the New York Comic Con 2008, DC Comics gave away pins featuring Nightwing, Jason Todd, and Hush with the words "I Am Batman" beneath them.
During the storyline, Nightwing is ambushed by the International Club of Villains. He is later seen in Arkham Asylum, frothing at the mouth and presumably drugged, believed by the staff to be Pierrot Lunaire, a member of the Club. Scheduled for an experimental lobotomy by Arkham himself, he's spared by the ICoV taking hold of the Asylum, wanting to use him and Jezebel Jet, Bruce's fiancée at the time, as bait.
As Jezebel's capture is revealed to be a red herring, due to her being a part of the Black Glove, Nightwing's lobotomy is still pending, but he manages to escape by besting Le Bossu, and joining the fray between the Batman Family, the International Club of Heroes and the Black Glove itself. While he's forced to witness Batman's dragging down Simon Hurt's helicopter and seemingly die in a fiery explosion with his foe, he's shown holding Batman's cape, discarded during the fight.
Following the events of Batman's apparent death during Final Crisis, Nightwing has closed down shop in New York so as to return to Gotham. He has opted to give up on having a normal job, and instead intends to put all his effort into protecting the city. After his returns he confronts Two-Face and Ra's al Ghul, proving two of his mentor's greatest enemies that he is an equal to Batman after he defeated them. He also finds himself being tasked to raise Bruce's biological son Damian with Alfred.
During the events of the Battle for the Cowl, Nightwing is said to have become unapproachable and less emotional. He is seen by the Bat-Suit display cases, still mourning the loss of Batman. Nightwing is said to be resisting the idea that someone needs to take up the mantle of Batman, in spite of arguments from Robin and Alfred Pennyworth that it is necessary.[18] It is later revealed he has no objections to becoming the new Batman, but was ordered not to in Bruce's prerecorded message for him, saying that Nightwing and Robin could carry the torch.
Robin later informs Grayson that someone is masquerading as Batman, using similar weaponry to their own. Nightwing is later forced to rescue Damian after he is ambushed by Killer Croc and Poison Ivy. However, Nightwing's glider is shot down, and the two are forced to crash land into a skyscraper. In order to give Damian time to escape, Nightwing offers himself up to the hit squad that is after them. He is about to be shot when he is rescued in a hail of gunfire by the Batman impersonator.
This eventually leads to Dick confronting Jason Todd, who has been posing as Batman. After a long battle between the two, Jason refuses Dick's help, while hanging on to a protruding ledge over Gotham's bay, Jason lets himself fall into the water.[19] After returning to the cave, Dick assumes the identity of Batman, with Damian as the new Robin.[20]
The New 52

In September 2011, The New 52 rebooted DC's continuity. In this new timeline, Grayson's costume changed the color of the "Nightwing symbol" from blue to red, and the emblem rolled over the shoulders, rather than traveling down the arm onto the middle and ring fingers. The costume also shifted from a skin-tight unitard look to an armored, full body suit, with spiked gauntlets such as Batman's rather than simply long gloves.[21]  Dick, along with all other members of the Batfamily, was a few years younger than previous incarnations. Despite being in his early twenties as opposed to his mid-late twenties, he was drawn a bit shorter than in his pre-relaunch frame. Starting with issue 19 there was a change in the suit.
After the events of Flashpoint as part of The New 52, Nightwing was relaunched with issue #1. Grayson resumes the role of Nightwing following the return of Bruce Wayne. The new series, written by Kyle Higgins, opens with Grayson having returned to Gotham, when Haly's Circus comes to town. Through a series of events, Grayson inherits the circus and is working through internal struggles with his past as he investigates the secrets the circus has brought about.[22]
During the events of Death of the Family, a Batman Family crossover, Haly's circus is targeted by the Joker. As a result, the circus is burnt down and the circus members leave. Dick is left feeling depressed and lost as a result of this and the death of Damian Wayne, the new Robin, and is at a loss for what to do with his life. However, when Sonia Branch reveals to him that she believes her father, Tony Zucco, is alive and living in Chicago, Dick makes the decision to take him down. Therefore, in 2013 Nightwing relocated to Chicago to hunt down Tony Zucco and also take down The Prankster, a new supervillain hacker in Chicago.
As part of the Forever Evil storyline, Nightwing's identity is revealed on every electronic device in the world when Superwoman takes his mask off.  Nightwing was captured prior when bringing Zsasz to Arkham Asylum and mistakes Owlman for Batman, which leads to Owlman knocking Grayson out. Currently, Grayson is being held captive by the Crime Syndicate. Owlman plans to ask Grayson to join them to fill in the spot of Earth-3 Richard Grayson who was Owlman's sidekick Talon who died when the Earth-3 vigilante Joker killed him and put his body parts in boxes for Owlman to find.

During his captivity, Nightwing is imprisoned in a containment unit built to hold Doomsday, with his heart monitored to set off a bomb should he attempt to escape. The alliance of Batman, Lex Luthor, Catwoman, Captain Cold, Bizarro, Sinestro, Black Manta and Black Adam break into the fallen Watchtower in order to free him but also to sabotage the Syndicate. When they are detected, the bomb is triggered to detonate in minutes. Batman tries to free Nightwing, but Luthor, believing there is no time, incapacitates Batman and Catwoman before suffocating Grayson until his vitals drop and he appears dead. The bomb is deactivated. An enraged Batman begins to brutalize Luthor, while Luthor tries to tell him that there may still be time to revive Dick before he is gone for good – and so they do. However, with his secret identity compromised, he gives up the Nightwing persona and is persuaded by Batman to fake his death and infiltrate the Spyral organization.
On January 21, 2014, DC Comics announced that the series would end in April with issue 30. It was succeeded by Grayson, 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,[23] 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.
Collected editions
Most of the original ongoing Nightwing series was collected in several trade paperbacks while the series was being published. Beginning in 2014 the series was then reprinted, with the new editions including material that had been omitted from the previous run of trade paperbacks. Both the New 52 and DC Rebirth ongoing series have been collected in trade paperbacks as well, during their publication.

At the end of the movie, he pilots the Batwing to rescue Batman, Talia and Damian.
In Batman vs. Robin, Nightwing returns to help train Damian while Batman is busy investigating the Court of Owls. Dick is dating Starfire in this film (as he called her "Kori", matching the redhead image on his phone), who phones him and tries to entice him to come over to her place.
In Batman: Bad Blood, Nightwing is forced to take Batman's place and don his spare costume during the time he's missing. He later helps Batman break free of the conditioning Tailia put him through.
