|Bio: While not affiliated with the Justice League, Nightwing
watches over Blüdhaven, a city with a population of 1.2 million. When he
moved to the 'Haven from Gotham City is unknown.
Note: Nightwing's appearance in "Grudge Match" was a cameo in the
strongest sense. He was seen along the top of a building next to a row
of Gargoyles. He then turned his head and the identifiable mullet from
his The New Batman Adventures design was rim light by the city lights.
He did not speak and was simply thrown in as a nod to fans. His
appearance held no relevance to the story.
