After the Hulk rampages through a monolithic statue of Ben Grimm, a mega-monster battle breaks out! The Green Goliath and the Thing come to blows, but their duel is halted when both combatants are presented the opportunity to revert to their human forms...permanently.
We begin with Ben on Yancy Street, having just taken a tomato in the kisser from a local teenager. Afer a quick flashback to tell us the origin of Ben and the rest of the Fantastic Four, we resume with Ben chasing down the kid and his friends only to be unexpectedly teleported away.
Meanwhile, out in the deserts of Utah, a sculptor is just finishing his masterpiece- a sculpture of Ben Grimm as the Thing, probably about 50 foot high. Unfortunately, the Hulk is bounding through that same desert, and finds and destroys the statue. After a quick pause to learn the origin of the Hulk, we find the Hulk angrily smashing the statue, declaring "Hulk hates Rockman!" As the Hulk turns on the sculptor, Hulk is also unexpectedly teleported away.
The Watcher assumes the role of narrator, and we learn that the Thing and the Hulk have been pulled to the planet of Matriculon by Stamben Malelet, a local bureaucrat. He needs some people to deliver a document to an important scientist from the clutches of a local criminal, and those people need to be large, rugged, and not too smart. So, he's chosen our heroes.
The Thing and the Hulk materialize on Matriculon, and we're told the Hulk is being bombarded with "positive cerebral ions"and will remain relatively calm for the next day. The two are then offered, in effect, two wishes if they'll retrieve the scientist. These wishes include the possibility of both Ben and the Hulk being premanently restored to their human forms. Ben eventually agrees, but the Hulk doesn't care. Ben tells the Hulk he can promise him something if he helps- a "good time," and the Hulk agrees.
So, on a planet full of aliens in a far distant solar system, the two set off on foot cross-planet to try to locate the missing scientist...
