Nightwing

Nightwing, real name Dick Grayson as a character of DC Comics.

Context
Richard 'Dick' Grayson is the youngest member of a family of acrobats and trapeze artists known as the Flying Graysons. Dick witnesses an attempt to extort money from the circus that employs them. When the circus manager refuses to pay, mobster Tony Zucco sabotages the Flying Graysons' show, killing the entire family. Dick is the only survivor. He is taken in after the death of his parents by Bruce Wayne. Dick wants to avenge his parents' death, and asks his guardian to find the culprit. Bruce Wayne refuses, trying to convince him of the futility of this act. When Dick tries to take justice into his own hands, he discovers that Batman is Bruce Wayne. He then asks the Dark Knight for help and assumes the identity of Robin.

While fighting crime alongside Batman, he forms the Teen Titans, a team of teenage superheroes, with Kid Flash and Aqualad, and becomes their leader. As a young man, Dick Grayson increasingly distances himself from his mentor. An argument breaks out between Dick and Bruce when Robin is injured by the Joker. Batman eventually chases him away, forbidding him to wear the suit again.

Dick Grayson returns to the Young Titans to save his friends who had been betrayed. He definitively emancipates himself from his mentor and takes on a new identity as a hero, Nightwing. This new name was inspired by a Kryptonian story Superman told him.
