As a writer, my job is to think of evil ways to destroy the world and save it. What could be more fun?
Anything is possible in the superhero world.
At first I was thinking of it as superheroes who happened to be teenagers. Then I realized, no, I'm writing about teenagers who happen to be superheroes. Thinking like that changed everything for me. I started approaching the stories through the characters' core emotions, rather than leading with the superpowers.
I get letters from adults saying that they love the books because they are more in-depth with characterization than the comics. The luxury of writing a whole novel is you can really explore who the characters are.
