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.

There's nothing comparative to Damien [the current Robin] or any of the other characters. I love those characters. And this isn't, "This is better than that." I think a couple of people misread what we had said in the first issue about that stuff.

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.

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 got fascinated by the idea that our universe itself is comprised mostly of dark matter and dark energy. Things that we can't perceive at all, and we've only discovered that relatively recently. So it's almost as if our universe is the foam on the ocean of things that we can't see, or know, or perceive, and yet we feel the affects of those things right and left.

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

I always, always got to be the last man standing.
