"This Monster Unleashed!"
The Hulk has taken the reluctant Betty Ross and fled to New York City. Meanwhile, the Communist Chinese have dumped a monster on America's doorstep, a savage who was exposed to their nuclear weapon tests. Now the creature is a radioactive behemoth on a rampage, known as the Missing Link. The Hulk tries to stop the monster from threatening Betty when the military arrive on the scene, carrying a device built by Mr. Fantastic that will stop the threat of the Hulk. All they do is manage to transform the Hulk into Banner just as the Missing link bears down on them. 20 pages.
