Marvel Two-in-One Annual #4

This 1979 oversized annual — 48 big pages — teams the Thing with Black Bolt for a story titled "A Matter of Gravity," and the cover by Joe Sinnott makes the stakes immediately clear: a massive, red-skinned Graviton dominates the foreground, grappling with the rocky orange fists of the Thing while Black Bolt is sent hurtling backward in a burst of energy above a chaotic city street. A speech balloon from Ben Grimm declares "Now ya done it, Graviton — ya got me mad! And that means it's Clobberin' Time!" — about as inviting an entrance to a super-powered slugfest as 1979 Marvel could offer.
