Batman was human. He had no powers. He stood next to Gods and said, "I handle my city.

I really wanted to make sure that if we set Duke up, that he's set up the right way and he's his own hero for the right reasons.

A post-9/11, modern take being Batman training people to be the heroes they know they can be on their own.

I spoke to Geoff Johns a lot. We went back and forth, and found a way to bring up the best qualities in his personality and psychology and also fill a niche in Gotham that we've never seen. It became about is there a way to really plant this hero in Gotham and say this is someone you haven't seen before - both in terms of who they are as a person and who they are as a hero.
