I was on Batman with "Superheavy" or "Zero Year" where there was a lot of fun and bombast, but it was also personal. [In All-Star], I wanted to take that to its complete extreme, like the end of the Earth extreme, where it's over-the-top humorous, yet at the same time really deeply about what I think is of this particular moment in time, at least for me. The things I'm terrified of and the things I'm hopeful about. My life is the page.

Having that North Star for every story [about Batman] is really key for me. It allows me to go farther and farther off the reservation.

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.

What I'm interested in exploring with Clark Kent is when you have the power to do something that goes beyond what you think is the right thing to do and the difficulty of that. Meaning, to be Superman also means to withhold a lot of power. He could reshape the world however he thinks it should be. But Superman doesn't, historically, do those things. He allows a certain level of self-governing and a certain level of independence, I think out of an admiration for humanity. Because he's inspired by the best in us and he challenges us to inspire each other to be the best that we can be.

Duke is a character who believes that heroism and the Robin mantle can exist entirely separate from Batman himself.

If I know what something's about, and I can always have that touchstone, I feel like I can reach for really ridiculous humor and also go really dark in terms of the things I'm afraid of.

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