Origin
Young Richard “Dick” Grayson had a charmed life. He was a member of a family of traveling circus performers known as the Flying Graysons. There he learned acrobatics, showmanship, and circus skills.

Then one day, in the middle of a performance, someone cut the ropes to the trapeze act and Dick saw his family fall to their deaths. Dick sought out the man that killed his parents and was saved by Batman when the killer also tried to end Dick’s life. Batman later adopted Dick as his legal ward and Dick moved into Wayne Manor.

Unfortunately, Dick felt like an outsider as Bruce Wayne kept his distance, not wanting the Bruce Wayne “persona” to become the surrogate father.
Later, Dick tracked down his parent’s killer a second time, and was again saved by Batman when he was beaten. Batman later revealed his identity and offered Dick the job of sidekick. Dick agreed and was trained by Batman in martial arts, detective work, tracking, and other skills. He became Robin, Batman’s partner in defending Gotham from evil.

Dick flourished as Robin and became a leader in his own right by helping to establish the superhero team the Teen Titans. Things began to sour between Robin and his mentor, though, as Bruce became colder and more calculating in his crime fighting.

Things came to a head when Dick decided to leave the Bat family and stop being Robin. In a conversation with Superman, Dick heard about an old Kryptonian legend of Nightwing, and with Superman’s blessing Dick decided to take up the Nightwing Mantle.

As Nightwing, Dick cleaned up the city of Blüdhaven, became an honorary member of the JLA and leader of the villain hunting team The Outsiders, and helped save the world countless times. 

More recently, Nightwing prowls the streets of New York City.
His relationship with his former mentor Bruce Wayne is repaired and Dick has become a mentor of his own with the new Robin, Tim Drake.
