There Is No Justice League
Richard "Dick" Grayson
Dick Grayson possesses the peak athletic strength and endurance of a man in his mid-twenties who regularly engages in intensive physical exercise. His martial arts skills rival those of Batman. He is a master of dozens of martial arts disciplines and was rigorously trained by his mentor in everything from escapology to criminology, fencing, stealth, disguise, and numerous other combat/non-combat disciplines. Dick Grayson is 5’ 10" (1.78 m) and 175 lbs (79 kg).
Nightwing is a master of a half-dozen martial arts disciplines (including aikido, savate, judo, and capoeira) with an emphasis on aikido, as well as being armed with twin Eskrima sticks made from an unbreakable polymer. He also carries several dozen modified batarangs (called wing-dings) along with de-cel jumplines and gas capsules.
Grayson is a prodigious natural athlete, possessing a peak human level of agility/acrobatic skills. He is regarded as the greatest human acrobat in the DC Universe. He is the only human on Earth who can do the quadruple somersault (formerly one of three, the other two being his parents). Having had the finest education as Bruce Wayne’s ward, he fluently speaks in English, French, Spanish, Russian, Mandarin, Cantonese, and Japanese and has some knowledge of Romany, the alien language of Tamaran, and American Sign Language. He is also a brilliant and experienced strategist with superlative leadership skills, having served as leader to the Titans, the Outsiders, and even the Justice League. Additionally, Dick’s interpersonal skills and efforts to remain in contact with other heroes makes him a master at rallying, unifying, and inspiring the superhero community, a skill in which he has surpassed his mentor.
Besides his resources as Bruce Wayne’s adopted son and heir apparent, Dick’s parents also left him a trust fund which Lucius Fox turned into a small fortune. Although it is not comparable to Bruce Wayne’s wealth, it has been enough to maintain his Nightwing equipment, purchase the rights to Haly’s Circus (saving Dick’s former home from financial troubles), and secretly buy his former Blüdhaven apartment building at 1013 Parkthorne Avenue.
The youngest in a family of acrobats known as the “Flying Graysons”, Dick watches a mafia boss kill his parents in order to extort money from the circus that employed them. Bruce Wayne, secretly the superhero Batman, takes him in as his legal ward, retconned in some cases as his adopted son, and eventually as his crime-fighting partner, Robin. He is written out by many authors as the first son of Batman as well as his prodigal son.
Throughout Dick’s adolescence, Batman and Robin are inseparable. However, as Dick grows older and spends more time as the leader of the Teen Titans, he retires as Robin and takes on his own superhero identity as Nightwing to assert his independence (others would fill in as Robin). As Nightwing, Dick leads the Teen Titans and later the Outsiders. Following the events of the Zero Hour miniseries, he temporarily replaces Bruce Wayne as Batman. In an eponymous series, launched in 1996 and continuing until 2009, he becomes the protector of Blüdhaven, Gotham’s economically troubled neighboring city. Following the destruction of Blüdhaven, at the command of Deathstroke, Nightwing relocates to New York. Following “Batman: Knightfall”, Dick Grayson takes up the mantle of Batman while Bruce was recovering from a broken back as he considers Dick his prodigal son.
After the events of “Batman R.I.P.” and Final Crisis, Dick moves operations to Gotham to protect the city following Bruce’s apparent death. Despite Bruce’s will instructing him not to, the chaos in Gotham following Bruce’s disappearance prompts Dick to take up his mentor’s identity once again as Batman. With Bruce’s return, Dick once again picked up his previous identity as Nightwing.
