Fantastic Four #178

January 1977 brought Marvel readers this action-packed clash as the cover — penciled by John Romita and inked by Joe Sinnott — throws the entire Fantastic Four into battle against the Frightful Four. The Thing takes center stage, trading earth-shaking blows with a massive grey powerhouse called the Brute, while the Human Torch blazes nearby, Mr. Fantastic and the Invisible Girl fight their own opponents below, and a purple-costumed villain unleashes a whirling rope weapon in the corner. With the cover boldly promising "At Last! The Showdown with the Frightful Four," this one has the feel of a confrontation that's been building for a while — and the interior story, "Call My Killer — the Brute!" by Roy Thomas and George Pérez, looks ready to deliver on that promise.
