looks like robin or nightwing.... maybee even riddler in a batsuit, not batman. No other people around for reference and you can tell his build is not large enough to represent batman regardless of the actor. And the collar on the cape is a feature on robins cape, never batmans, making my head hurt.
Getting heavy Arkham vibes here, very mechanical in nature. It sure what to make of it yet until we see it clear. You can’t even see his cowl that well. First vibes I’m getting are he’s too thin, but then it’s too dark to tell either way.
