I'm really proud of all the stuff we've built with Green Lantern - from Larfleeze to the different corps. The universe has expanded and will live well past my run. It was more than just telling another story, but really giving back to the character by expanding and adding to their mythology.
I don't know who made the first Aquaman joke. I'm sure it was comics readers; maybe we all did. But it's the idea that the perpetuated story of Aquaman is that he only has powers in water, and he talks to fish. I think it's the idea of him in the middle of a city just doesn't make a lot of sense to people. It's just the character itself.
'Justice League' takes place in the past, and Aquaman has a lot more to prove. He's just starting out. The perception is already beginning, and all these super humans are just showing up, and here's Aquaman. The perception is, 'What's next? Now we've got a guy talking to fish. What can be next?'
Batman and the Flash have a whole lot in common behind the mask. They've both experienced loss, know forensic science, and are both a bit introverted. In 'Flashpoint,' Thomas Wayne thinks Barry is crazy, but Barry thinks Thomas is crazy. It'll be really fun seeing those two trying to figure things out.
Evil is relative - and what I mean by that is that our villains are as complex, as deep and as compelling as any of our heroes. Every antagonist in the DC Universe has a unique darkness, desire and drive. And the reason for being of 'Forever Evil' is to explore that darkness.
