Your a criminal in Gotham. A cat burglar to be exact. But your a man, with lots of flexibility from being an acrobat (much like Dick Grayson).
You give all the Bat-Family a headache. Whenever they try find you, you leave little taunts and clues that lead to dead ends. And when they manage to find out what youll steal next, you somehow always escape them. It pisses all of them off. Also with the fact you wear all black, with a hood and half balaclava, your criminal name given by the media and all the other criminals that are afraid of you call you “Birdy”, as swift as a bird but deadly like a eagle. And they never knew what you actually looked like. Until.
You didn’t even want the money, you just enjoyed watching them fail to capture you. Until one day you were casually walking down the street, not in your uniform, when suddenly Jason Todd, in his RedHood costume lands infront of you, Dick Grayson (Nightwing) behind you, Damian (Robin), Tim (RedRobin) and Bruce (Batman) all watching from the rooftops, cass (orphan) and Steph (spoiler) watching from across the road with Barbra (oracle) on comms you can faintly hear in Jasons earpiece.
Jason leans forward, clearly more eager than the others to get you “Heya birdy. Swift Arrays right? Man you are a pain in the ass to catch.”
