Kull, the Conqueror #4

Marvel's sword-and-sorcery saga surges forward in this 1972 entry, subtitled "Night of the Red Slayers!" — and John Severin's cover makes the threat feel immediate. Kull dominates the scene, muscles straining as he sword-fights through a press of armored warriors while shielding a blonde woman in green, red-helmeted soldiers closing in from every angle. It's a vivid snapshot of the barbaric world Robert E. Howard's king-conqueror inhabits, brought to life inside by the combined talents of Gerry Conway, John Jakes, Marie Severin, and John Severin.
