Bumping this for interest.

I've added mini-timeline, hopefully someone will post a character soon.

I will post a Ra's Al Ghul sheet later.

EDIT: Trying to work on history, and will likely finish it up tomorrow.
Anyone wants to create a new Batman, or play Oliver Queen, or some other DC character, go for it. Or even some Marvel character, that's fine. Having Arrow fight alongside Daredevil would be cool.
