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.

The thing with Superman is that he's completely emotionally open to the reader. Meaning what he tells you is what he's feeling; there's a transparency there. And what he tells other characters is usually as transparent as can be. What he says he believes in. So there's an honesty that is both really inspiring writing the character. One thing I love about Clark Kent is that there is a badassery that you don't see a lot. Even as Superman, he's always kind of restraining himself. When you challenge him, I think there's nobody that has a stronger spine than Superman.

You take the thing that is the worst thing that could have happened to you, the worst challenge in your life, and you turn it into fuel. You don't give up. And that's what Gotham is about.

- If I tell you, will you let met go? - You bet, partner. [...] - You promised! - Nope. I said "you bet." You did ... and you lost.

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.

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

[Duke] is the same way that Harper Row is a character who doesn't want to know who you are beneath the mask, and that makes her interesting. She'll show up and help Batman, but she never wants to know if he's Bruce Wayne.
