Super-Villain Team-Up #13

The cover of this 1977 Marvel issue says it all — Dr. Doom's armored visage looms enormous in the background beneath a sweeping green hood, while a bare-chested Namor the Sub-Mariner clashes furiously with the armored Warlord Krang in the foreground, blasts of energy lighting up the struggle. Cover pencils by Keith Giffen and inks by Frank Giacoia give the scene a real sense of underwater menace, framed by the urgent question "Who Shall Save Atlantis?" With Bill Mantlo and Giffen also handling the interior story, this issue pairs two of Marvel's most formidable antiheroes against a dangerous undersea rival in a way that feels genuinely high-stakes.
