I think thing that makes Batman so endlessly interesting is that he's one of the most flawed and deeply human characters, even though he seems completely the most inhuman and infallible in costume. Psychologically he's one of the most complicated in both his strengths and his weaknesses. For me, one of his great strengths and weaknesses is that confidence. His emotional self-protection is one of the things that makes him heroic and sacrificing; he doesn't have a personal life. He sacrifices those to be the best hero he can be.

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.

[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.

I had to fight for wingdings. Batman needs to curse sometimes!

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

I love The End of the Batman story. I have my original copy, the hardcover, at my house from when I was a kid, whenever that was,'88 or '89. It was very influential to me because it was so explicit in touching on the notion that Batman might be mad and that he might belong in the mad house.

One of the things that's great is that Batman is a character that lends himself to very personal stories.
