Interviewer: Charles, how do you plan to differentiate between whose power-set supersedes and takes precedence over another? Even who throws the first punch?
Soule: One of things that I would like to do is have the way they approach battles grow over time as they get to know each other better so that fights become more coordinated. Wonder Woman has the background as a warrior dating back to when she was very little. Ares, in the New 52, was her warrior teacher when she was 12. She has a strategic, practical approach to battles where Superman, it's not like he rushes in guns-a-blazing, but he has a slightly less schooled approach to his attack.
When you are constructing a battle scene with characters this powerful, you have to differentiate between the two. Otherwise, it's just two people punching things. Obviously, Diana has her lasso. She has her sword. She has military training. While Superman has his various superpowers like heat vision, x-ray vision and stuff like that so the way that those can be combined and played out is going to be a lot of fun.
Interviewer: What can we expect from the opening arc? Which challenge or villain do they face?
Soule: I don't want to share too much just yet, but what we're planning on doing in the first main story arc is based on seeds that have been planted in "Action" and "Superman" for a while. Once you see the direction that it's going to go, I think you'll say, "Okay. Cool." At the same time, it's very important to me, actually it's crucial that we make this incredibly accessible. I don't want a book steeped in Superman and Wonder Woman continuity. Anyone who picks up an issue should be able to figure out what's going on from within those pages.
The goal is to really show people something new about these characters and maybe have them try a book about these characters when they aren't necessarily reading some of the other books. It's just about creating another access point for these fantastic characters. We want to make it a satisfying experience for those reading all of the books but also who haven't been reading any of the books.
