This is how i would picture Jason making his first appearance in the Arkham games. He's fought tooth and nail to find his way back to Gotham to clean up the city like only he can knows how, kill all the criminals and you kill off crime. Jason is still a little crazy after Ra's gave him a dip in the Lazarus pit. Jason's been hitting Batman and Nightwing's secret caches around Gotham and Bludhaven and he's taken the equipment he needs. I thought mixing bruce and dick's suits into one would make the most sense since he's stealing pieces from wherever and whoever he can.
