What Happened Every Time The Thing Fought The Hulk?
1. Fantastic Four #12-13
Before, when the Thing turned back human in the middle of fighting the Hulk, it ended...less than ideally for him. However, back then, he didn't have Alicia around to protect/impress, so it makes sense that he'd be a bit more motivated this time around.
When Ben and his new bride Alicia head off to finally take a much needed vacation, the Hulk - controlled by Alicia's father Puppetmaster, interrupts and attacks him.
The Thing, knowing there are too many innocent people around to safely fight, and also knowing he's about to turn back human for the next two weeks in just a few minutes, actually swallows his pride at first and acquiesces the title of strongest one there is to Hulk, which might have worked on a Hulk in his right mind. But the Puppetmaster makes him attack anyway.
The fight, due to the Thing being kept on his back foot because of the above mentioned handicaps, is brutal as hell, but right as the time limit runs out, the Thing manages to put an end to the fight with one last punch that shatters the rock on his arm with the force, knocking out the Hulk right as Ben transforms back to human.
