Nightwing (Arkhamverse)

Nightwing (Richard John "Dick" Grayson) is a playable character in Batman: Arkham City. He is only available through DLC and does not impact the storyline.

History
Dick Grayson was part of a circus family, dubbed the "Flying Graysons" for their death-defying stunts and acrobatics. After a performance that Bruce Wayne was in attendance to, Dick was left as an orphan by the hands of the mob. Feeling sympathy for the child, Wayne decided to take the boy in as his own and treat him as family. Eventually, Batman gained enough respect and trust for Grayson that he bestowed upon him the great secret, even going as far as to train the acrobat and develop a new sidekick, Robin. Through hard work of training and exercising, the duet was almost unstopable. After years of partnership, Dick grew tired of Bruce's power over him and his strict personality. Once Grayson was through with puting up with it, he left the Bat to fight crime on his own, and developed a new alias, Nightwing, a Kryptonian god (being that Dick always looked up to Superman).

Batman: Arkham City
Nightwing is available for DLC on November 1st, 2011. He will include the playable character, his costume from Batman: The Animated Series, and two additional challenge maps, Wayne Manor and Main Hall. He will be playable on all other challenge maps also. Nightwing does not make an appearance in story mode, unlike all of the other playable characters.

Abilities
Nightwing was taken under the wing of Bruce Wayne, and was given the mantle of Robin the Boy Wonder. To do so, he had to be trained by the Dark Knight himself. He was trained to physical and mental peak, being almost as trained as Batman. His strength is beyond most humans, barely falling under uncanny.
