Nightwing
Nightwing was the first of Batman’s Robins. When his family was killed in a tragic circus accident, Bruce Wayne adopted the young Dick Grayson and helped him bring Tony Zucco to justice. Over the years, Dick grew up and left the Robin identity for the moniker of Nightwing, going so far as to leave Gotham City for new locations like Bludhaven and Chicago in the New 52. Most recently, he’s become an agent of SPYRAL in the monthly Grayson comic.
Dick becoming a spy rubbed fans the wrong way, but over the past few months has grown on them. It’s here where the story would be set, alternating between his present time in SPYRAL and flashbacks as a child acrobat, Robin, and eventually Nightwing. Combat would work as it does in the Arkham games, though he wouldn’t have the same arsenal his mentor does. The game could draw influence from various portrayals of Robin over the years, from the classic animated series to his role as a hacker in the Young Justice series.
