Bruce sees in this character - who fought all the way through "Superheavy" when his parents were missing, and now is determined to fight even though his parents are telling him he's worth nothing - the essence of Batman.

It's one of the worst nightmare situations we could create for a young character, having the people who are supposed to believe in you keep telling you you're nothing.

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.

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.

This one's like that because it's about these things that I think weigh heavily on me in terms of my own failings and the things that I worry about and my personal demons. Is the sum of my personal demons greater than the things that I like about myself? Is this moment - because it's a particulary high tension, scary moment for all of us in terms of the global climate - going to bring out the best or the worst in us?

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.

[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.
