"It Walks Like a Man!"
A submarine trespasses on Atlantean territory, dumping a canister of radio-active waste. The presence of the radiation spawns an inhuman monster, who causes carnage to a local military installation and attacks Atlanteans. While Namor tangles with the monster, the military prepare to retaliate for what they think are aggressions on the part of the Sub-Mariner.
After having defeated the Abomination for the safe recovery of Betty Ross, the Hulk disappears. Bruce Banner has gone into hiding. Betty grieves, and Rick Jones has the Teen Brigade scouring the world to no avail. It is ultimately the stress of finding a cure that triggers Banner's transformation, and when the Hulk looks for a way to leave the mad world of Mankind behind, he spots a UFO, and seeks to grab it for a ride to any other world. What he mistook for a spacecraft is the Silver Surfer.
