The original Robin, also known as Dick Grayson.
Quite possibly the coolest part of the Batman everything.
Nightwing is a badass mofo with long black hair and ninja moves. Very shweet!
Dude 1: Dude! Batman is on! Let's watch!

Dude 2: Is it the one with Nightwing?!?

Dude 1:...No.

Dude 2: Well fuck that then!

Nightwing is Dick Grayson, the first Robin. He left Gotham and founded the first Teen Titans and later turned from Robin to Nightwing. He patrols Bludhaven, a sad crime-ridden excuse for a city.
Robin matured... a lot. Rawr.

Nightwing (Dick Grayson/ Former Robin) is a well known character in the comic universe. But oh boy, what he's most famous for is his masterpiece of an ass. He really sets himself up, skin-tight suit, acrobatics that require ultimate flexibility, absolute menaces that sit behind the comic art. My god, there hasn't been a day where Nightwing's ass hasn't been the highlight of my comic. And no, this is not a cry for help.
"Objectively speaking, who's the big booty bitch of DC? Catwoman, right?"
"Dude..It's Nightwing. Have you seen Nightwing's ass?"
"Shitttt, how is that thing even allowed?"
"Swear."
