Namor, the Sub-Mariner Epic Collection #1

In "Chapter 5 Return to the Deep!", Namor, the Sub-Mariner, faces off against the colossal Giganto in a clash that sends shockwaves through the ocean floor. With the Human Torch sweeping him and his foe into the sea, Namor’s final vow—“I'll be back!”—hangs in the water like a promise.

In "The Master of Flame vs. The Monarch of the Sea!!," the Human Torch seeks to prove himself by challenging Namor, the Sub-Mariner, in a clash of wills and powers—only to trap the sea king beneath the ocean floor and return to the surface, leaving the outcome of their confrontation unresolved.

When the Avengers worry over the Hulk’s rampage after his departure, their search leads to a clash with the green giant—until Namor intervenes. Drawn into the conflict, the Sub-Mariner and Hulk form an unexpected alliance against the team, setting the stage for a tense confrontation beneath the waves.

In a frozen Arctic mystery, Namor’s assault on an Inuit village unleashes Captain America, frozen since World War II. When the Avengers rescue him, they’re soon confronted by an alien who turns them to stone—offering salvation only if they help recover his shattered spacecraft. As Cap and Rick Jones pursue the alien’s trail, the team faces a shocking clash with Namor and his undersea forces, testing their unity in a battle that could reshape their fate.

In a twist that sends shockwaves through the underwater world, Namor finds himself at the center of a clash between ideologies when Magneto invades his realm with an offer to join the Brotherhood—spurred by a rumor that he might be a mutant. Drawn in by the Scarlet Witch’s enchantment and the promise of purpose, Namor hesitates, caught between loyalty and allegiance. As the X-Men arrive to stop the invasion, he must decide where his true allegiance lies—before the tide turns.

In "The Sub-Mariner Must Be Stopped!", the Fantastic Four’s usual antics take a sudden turn when Ben and Johnny, eager to impress a pair of LIFE Magazine reporters, decide to intercept Namor before he reaches New York. Their plan goes awry when Namor appears, seemingly anticipating their ambush, and the resulting clash leaves him disillusioned—convinced he’s been misled. Reed and Sue arrive just in time to see the fallout, and the brothers face the consequences of their reckless stunt, as a furious Namor declares their next encounter will be final.

In "In Mortal Combat with... Sub-Mariner!", Namor takes a dramatic stand against humanity, hiring lawyers Franklin and Murdock to fight for his people in court—only to find the system utterly deaf. When diplomacy fails, he deliberately arrests himself, but when justice remains out of reach, his rage ignites a violent confrontation that draws in Daredevil, who tries in vain to stop him. The story ends with Namor retreating to the sea, not in defeat, but to protect Atlantis from a new threat.

Namor returns to Atlantis to find his throne seized by Warlord Krang, and after being betrayed by Lady Dorma, he’s imprisoned as a traitor. With only the legendary Trident of Neptune offering a chance to reclaim his kingdom, Namor makes a daring escape to begin his quest.

In "Escape... to Nowhere!", Namor plunges into the Forbidden Deeps on a desperate hunt for Neptune's Trident, while Seaweed Man is sent by Krang to halt him. Back in Atlantis, the people stir with unrest beneath Krang’s oppressive rule, setting the stage for a clash of power and destiny.

In "A Prince There Was!", Namor races through the depths in search of the fabled Trident of Neptune, dodging a creeping seaweed threat before being overwhelmed by the blinding lure of the Diamonds of Doom. Meanwhile, back in Atlantis, Krang’s frustration with Lady Dorma’s cold demeanor reaches a breaking point, leading him to banish her to the mysterious realm of the Faceless Ones.

In "By Force of Arms!", Namor must navigate treacherous waters both above and below the sea as he journeys to the land of the Faceless Ones to rescue Dorma, while Neptune's electric eels aid his fight against the Demon of the Diamonds. Back in Atlantis, the tide turns as the people rise in revolt against Krang’s rule.

In "The End of the Quest!", Namor fights to protect the unconscious Dorma as the Nameless Ones close in, only to be saved by Neptune himself, who bestows his trident upon the Sub-Mariner. With Dorma’s life hanging in the balance, Namor entrusts the trident to Vashti the Elder before rushing her to the revitalizer ray—just as Krang, lurking in the shadows, prepares to destroy them both.
