Namor, the Sub-Mariner #24

Namor and Wolverine go claw-to-claw in this March 1992 Marvel showdown, with the cover by John Byrne putting both combatants nose-to-nose in a tense, snarling face-off amid dense jungle foliage — Wolverine's adamantium claws gleaming between them. Billed as "Green War!" the image crackles with barely contained ferocity, capturing two of Marvel's most formidable bruisers at their most primal. Byrne handles the full creative package here — writing, art, inks, and lettering — with colors by Glynis Oliver rounding out a cover that's hard to look away from.
