Sub-Mariner #52

Namor and Sunfire clash in spectacular fashion on this Gil Kane and Joe Sinnott cover, the two powerhouses grappling mid-air above churning waters while a massive ship looms behind them — and those charged word balloons ("If that ship sinks — the Earth is doomed!" / "Then let it die, Namor!") make the stakes feel genuinely enormous. "When Sunfire Strikes!" delivers a charged premise for the interior story "Atomic Samurai," with Bill Everett handling writing and art duties. At just 20 cents, this 1972 Marvel issue pairs one of comics' great water-born royals against a fiery, formidable adversary in a way that's hard to put down.
