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.

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.

What Batman is saying is that, "I want to try something new that's more about this era and this moment." And I do think that it speaks to a modern take [as opposed] to a 90s take or a 2000s take being maybe the older program about having a sidekick.

First of all, what made him [Duke in "Zero Year"] captivating is this sense of somebody who wants to save the city regardless of whether Batman wants to or not, but has been inspired by Batman. He's always been - not combative with Batman or anything - but I think he has a sense that what Robin is and what heroism is in Gotham is something that's inspired by Batman and sort of separate from Batman.

The hope that they have legs. That's the biggest fear you always have creating new people. You love them, but then they kind of dissipate. Sometimes you don't get to write them as much as you'd like, like me and Harper Row.

With this particular series [The Cursed Wheel] I'm going farther in that direction than I've tried before in terms of the elasticity of the mythology.

On this global stage, Superman is someone that we can all look up to and he's almost kind of ultimately American.
