With the Leader seemingly deceased, Hulk (still with Banner's intellect) leaves the villain's lair in Rome, carrying the Ultimate Machine he stole from a Watcher (in the previous issue).
Hulk stops somewhere in the Alps and tries on the Ultimate Machine. He sees his friend Rick Jones in trouble mentioning the White House. But the device data torrent is too excesive. Hulk manages to pull it away on time before suffering the same outcome as the Leader.
That experience makes Hulk lose Banner's intellect.
Hulk leaps away, destination USA to save Rick, forgetting the Ultimate Machine which is later recovered by its owner, the Watcher.
When Thunderbolt Ross is informed that the Hulk is heading for Washington DC, he authorizes the use of the T-Gun, Banner's newest weapon. Strangely, its power is unknown by the military. A shot of the T-Gun hits the Hulk, and he is sent five centuries into the future!
Hulk arrives in that distant future, and is attacked by armored men. It seems not much has changed for the incomprehended monster!
