WARNING: The following contains spoilers for Robin & Batman #1, on sale now from DC Comics.
In the DC Universe, one of the most important parts of Dick Grayson's evolution from Robin into Nightwing is where Dick Grayson derived the name from. While hie leaving the Robin mantle behind was likely always in the cards, finding the correct moniker was something he spent a lot of time on. With his adult identity, Dick still wanted to instill more hope than the Dark Knight. And in Robin & Batman #1, by Jeff Lemire, Dustin Nguyen and Steve Wands, DC just offered a new answer as to how Dick found his new name.
Nightwing has always been linked to Dick's fascination with Kryptonian culture. In 1963's Superman #158, Superman and Jimmy Olsen got trapped in the bottled city of Kandor and were wrongfully blamed for a crime, and they went on to take on the identities of Nightwing and Flamebird. These were two winged creatures native to Krypton, which influenced the symbol on Dick's chest.
In a Chuck Dixon and Scott McDaniel story from 1999's Nightwing: Secret Files and Origins, Superman came to offer words of wisdom to Dick after he left the Robin title behind. The Man of Steel told him about a vigilante and outcast in Krypton who went by the name of Nightwing. Inspired, Dick used the legend to forge his new persona.
However, this first chapter by Jeff Lemire, Dustin Nguyen and Steve Wands alters that by diving into Dick's earliest days in training. Right after Bruce took him in from the circus, the young Grayson dons a black costume but ends up bumbling a robbery in a mission that almost kills him. Batman saves him and yells at the rash kid as he's not ready, which then motivates Dick to suit up in his red, yellow and green colors. But as he sketches, plotting his future and wondering if Bruce could be his new dad, he struggles to think of a name.
As he thinks about whether or not his mom's old nickname for him, "Robin," is enough to strike fear into the hearts of evildoers, he thinks of alternate names like "Nighthawk" and even "Nightwing," simply as he tries to think of a cool superhero name.
Dick quickly forgets about the "Nightwing" name, which sets him up to officially become Robin. While it's not clear if or how this interacts with the rest of Dick's past, it potentially strips the influence of Superman from Nightwing's history. Dick's superhero career takes a balanced influence from his two mentors, with Nightwing using Batman's tactics with Superman's optimism. While this nomenclature change potentially affects the explicitness of that influence, it doesn't ultimately change the hero that Dick grew up to be.
If anything, Dick's thinking here transforms "Nightwing" into something closer to home when he was alone and pondering the concept of family. Ironically, Titans had Dick choosing this name during a stint in prison, inspired by Alazul, a mythical bird who saved innocents. That wasn't as personal so it didn't register as much, but a young Dick coming up with a future title that helps him escape his turbid past and turbulent present with Bruce resonates much better as it showcases his wild imagination.
