During the "Batman R.I.P." storyline, Nightwing is ambushed by the International Club of Villains. He is later seen in Arkham Asylum, frothing at the mouth and presumably drugged, believed by the staff to be Pierrot Lunaire, a member of the Club. 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 fianceè at the time, as bait.

As Jezebel's capture is revealed to be a red herring, due to her being a part of the Black Glove, Nightwing's lobotomy is still pending, but he manages to escape by besting...

Dick's good looks and sensitivity have always made him attractive to others (in fact, it is something of a running joke that every female metahuman in the DCU is attracted to Nightwing). He maintains a tenuous friendship with Flamebird (Bette Kane), despite her long-held, unrequited feelings for him. Donna Troy, the original Wonder Girl, has also known him since childhood, and the two are particularly close and not afraid to admit that they love each other as brother and sister. However, there have been points in his past where Dick has fantasized about not only falling in love with Donna,...

From Wikipedia, the free encyclopedia
Nightwing is a name that has been used by several fictional characters in the DC Comics Universe. It was conceived as a Kryptonian analogue to the character of Batman, with Nightwing's frequent partner Flamebird based on Robin.

Robin, The Boy Wonder

He was first introduced in Detective Comics #38 (1940) by Batman creators Bill Finger and Bob Kane. Robin's debut was an effort to make Batman a lighter, more sympathetic character. DC Comics also thought a teenaged superhero would appeal to young readers, being an effective audience surrogate. The name "Robin, The Boy Wonder" and the medieval look of the original costume are inspired by the legendary hero Robin Hood, as well as the red-breasted American Robin, which parallels the "winged" motif of Batman. Dick Grayson was born on the first day of spring, son of John and...
