I was going for a stylized macho Batman but I see now that it looks more like the Hulk dressing up as Batman for Halloween. Oh well. I still learnt a lot though that's what counts I guess.
Didn't the other incarnation of Red Hood appear in Batman Origins? That might confuse things somewhat. There's been some odd developer quotes about the "Gotham Knight" not being Batman, but a separate character developed by Rocksteady. Given that Batman is clearly in the game from the trailer, I'm imagining someone else…
