When I first did 'Empire,' it was a severe break from everything I'd written up to that point, which is all very continuity-driven, super-heroic, and ethics and morals-infused. 'Empire' was a chance to break away from that.

If you go back and look at the first issue of 'Indestructible Hulk,' if you have a sharp eye, you'll catch something that I totally forgot to put in there. In my horror, I only realized after the fact that I took totally for granted that everyone in the world knows what triggers the transformation.
