"I felt it was important that — for Diana — that she isn’t just every other superhero guy’s girlfriend at some point. Because that’s a little insulting to her. It doesn’t really serve her terribly well, and it doesn’t really serve any of the traditional love interests of any of these characters." Characters like Lois Lane, for example.
"Greg was saying to me ‘Steve Trevor is a little bit Steve Rogers [aka Captain America].’ They’re of the same generation, they’re of the same era, traditionally. They’re good guys looking for a cause, and finding a modern version of that is providing Diana with a good guy that is completely and utterly unthreatened by her ability. Because he’ll just think that she’s awesome, because she is. And she’ll just think that he’s awesome because he is. And the fact that there’s an incredible power difference and genetic difference between them is irrelevant."
I couldn’t help but point out that the Steve Trevor she and Rucka have shown readers in the first few issues of Wonder Woman was already breaking the conventions of characters with similarly masculine, action-hero-type backgrounds by being depicted as loving and emotionally vulnerable — and by being depicted as shirtless and naked quite a bit.
"Oh good!" she responded, after I made it clear that I was not complaining in the slightest. "I love drawing him shirtless and naked, and there will be more of it."
