Fantastic Four #195

This 1978 entry in Marvel's flagship series puts Sue Richards — the Invisible Girl — front and center alongside the Savage Sub-Mariner, both straining against crackling energy beams fired by a massive armored robot adversary. The Thing, Human Torch, and the rest of the FF look on from portrait circles above, while the cover tagline promises they're all "helpless against the unleashed fury of the Rampaging Retrievers." George Pérez's pencils, inked by Joe Sinnott, pack the scene with kinetic tension, making this a thoroughly compelling snapshot of the team under serious mechanical threat.
