continuity reboots in 1985 and 1994, respectively, Nightwing was reimagined 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 Grayson briefly assume the title, including his fellow Robin alumnus Jason Todd.

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.

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, whose crimefighting tactics were similar to Batman's.

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.

Other items were lock picks, a first-aid kit, a mini-cellphone, flexi-cuffs, antitoxin assortment, wireless listening devices, and a small flashlight.

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.

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).

2) #118-122[13] run features Jason Todd wearing Dick's costume and killing in New York City which led to a police manhunt against Nightwing.

[14] The "One Year Later" storyline features a metahuman fashion designer named Cheyenne Freemont donning a modified Nightwing costume to help Grayson.

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 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.

[17] Following the events of Nightwing (vol.4) #114-116 Bruce adopts the suit and name while Dick Grayson has left Blüdhaven to cure his fear of heights.

"[18] Based on Nightwing's increasing popularity, DC Comics decided to test the character's possibilities with a one-shot book and then a miniseries.

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.

Devin Grayson then returned to the book to write the "Mobbed Up" plotline that involves Dick going undercover to take down a New York mafia family.

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.

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.

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.

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.

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.

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.

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.

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.

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.

[24] 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.

In the character's second appearance within the film series, Batman & Robin, Dick Grayson pursues being a vigilante on his own and wears the Nightwing costume design.
