It's the battle of the century! Iron Man versus the Hulk! Who will win? Brute strength against genius intellect!

The Mandarin is in the United States and has sent a Hulk robot to kidnap Tony Stark and Janice Cord who are once more attempting their merger deal. When the meeting is attacked by the faux Hulk, who kidnaps Janice, Tony changes into Iron Man.

Battling the fake Hulk across the city, Iron Man finally destroys the behemoth by knocking him into a generator causing a huge explosion. When the smoke clears, the severely damaged Hulk robot's true nature is revealed and Janice is saved. Although the Mandarin had failed in capturing Stark and Cord, he did succeed in something else entirely: Having viewed the entire battle, he has deduced that Iron Man and Tony Stark are one and the same.
