Bio: After college Dick Grayson left Gotham to travel the world
on his own, much like Bruce Wayne did in the years before he became
Batman. While living abroad, Dick studied many different crime fighting
techniques and reexamined his feelings about taking up the role of Robin
again when he returned to Gotham. He eventually realized he had outgrown
the role of Batman's trusted kid sidekick Robin, and set about
developing a new heroic identity all his own.
When Dick returned to Gotham, he moved out of Wayne manor and into a
downtown loft above an abandoned warehouse. Money from a generous trust
fund set up years before by Haley's Circus enabled Dick to buy the
building and he has turned its top two floors into his own high-tech
urban headquarters. True, Dick's fortune is small compared to the Wayne
billions, but he's got enough cash to keep his crime fighting alter-ego
in state of the art weaponry for years.
Batman was respectful of Dick's decision to go it alone. Like any
father-surrogate he knew his "first born" had to leave the nest sometime
and watched him go with a mixture of pride and regret. Now in his new
identity as Nightwing Dick still teams up with his one-time mentor, but
Batman often finds his one-time partner has new, and in some cases
radically different crime fighting ideas of his own.
Nightwing is quickly establishing himself in Gotham City as a young,
powerful and mysterious force for good. Nightwing uses his sleek
motorcycle to patrol the streets of Gotham. Barbara also likes the
change in Batman's former sidekick and is looking at Nightwing as a
romantic possibility, something she never could see in the old Robin.
It's established that Nightwing will eventually leave Gotham to
establish himself in Bludhaven as their prominent crime-fighter.
Bio (Cartoon Network): Batman's first partner, Dick Grayson's
parents were murdered when he was a boy, leaving him an orphan (much
like the young Bruce Wayne). Batman decided to take young Dick in,
honing his skills learned as an acrobat (with his parents) into a
crimefighting career. First as Robin, half of Gotham's Dynamic Duo, then
later as Nightwing, Dick Grayson has given as much to Gotham city as the
dark knight himself. His relationship with Batman becomes somewhat
antagonistic in later years, with Dick resenting Bruce's controlling
nature. But Nightwing and Batman have been known to work together
