Ben Grimm, better known as the Thing, is the original quintessential tough-guy of the Marvel Universe. But, because of his transformation, he's also the tragic member of the Fantastic Four. Ben was an ace test-pilot until exposure to intense cosmic radiation mutated him into a rock-skinned monster with immense superhuman strength. Ben's exterior is much harder than stone which gives him a rather gruff disposition; but deep down, he has a heart of gold.
