[@Ezekiel] Who's open up for being played? I was thinking maybe playing a Tim Drake Robin if that's okay with you.

As the Batman only appeared a few years ago, it would certainly be the first Robin, although it's more than possible for that to be Tim Drake.

The primary issue is you'd have to talk to Ruby about being a Robin, and she's quite busy IRL at the moment.
