Warren Ellis and Cary Nord really nail this one imo. No knowledge about the Ultimate universe is really necessary for enjoying this one, just understanding of the basics of Iron Man and Hulk. The study of the Hulk on Venus and Mars was incredible. We'll see how the whole thing pans out, but the first issue has excited me more than any other "superhero" comic in a while. Its beauty is in the science fiction thus far. But it's likely The Leader will become a common foe for both "heroes", creating a more comic-like story (which is appropriate and satisfying). Id vs Ego Hulk vs. Iron Man let's hope this one doesn't experience the endless delay of another unnamed Ultimate Hulk vehicle.
