“Who Strikes for Atlantis?”

From the depths of Marvel's 1968 Silver Age comes this dynamic chapter in Prince Namor's solo series, with a cover by John Buscema and Frank Giacoia that crackles with raw energy — Namor reels under the hammer blow of a powerful armored villain, while a crowd of monstrous figures looms ominously in the background. The title "Who Strikes for Atlantis?" promises high stakes for the undersea kingdom, and the cover delivers that tension in bold, kinetic style. Roy Thomas scripts and John Buscema pencils the interior, making this a fine example of late-'60s Marvel at full throttle.
