Speaking of the Hulk, you know that old saying that anything that doesn't kill you will make you stronger? Well, imagine the kind of stud that emerges after surviving a zapping by a gamma bomb. So it was that Dr. Bruce Banner got turned into the Incredible Hulk, a perennially pissed-off giant who manages to always find himself pitted against the U.S. Army.
Is he a man or a monster? That's a question left to readers by the character's creator, Stan Lee, who said the inspiration for the Hulk grew out of his desire to combine Jekyll and Hyde with Frankenstein.
What he gave us was a sulky, misunderstood misanthrope with enormous wrecking capacity. This is a specimen that can cross continents with a single bound!
