I tend to like writing long stories in comics. I worked on 'Flash,' 'Teen Titans' and 'JSA' for years. I always like diving into characters.

I've been writing 'Green Lantern' for a long time, and one of the reasons I've enjoyed it is because the depth of stories you can tell is pretty endless with space and everything.

'Flashpoint' is a showcase to demonstrate why the Flash is a major character, just like how we've done with Green Lantern. It's important that the Flash can hold his own.

The characters that have greys are the more interesting characters. The hero who sometimes crosses the line and the villain who sometimes doesn't are just much more interesting.

The ocean is 90% unexplored. It's a great canvas to paint Aquaman stories across, just like Green Lantern has space. It's more organic, which makes it different and interesting. It's alien, but it's terrestrial.

I didn't want to take the DC universe, put it in a box, shake the box and pour it out. I wanted to take the major characters and show what they could be like if they were put on a different path.
