Like a sudden riptide beneath calm waters, fan theories surged the moment Namor resurfaced in Avengers: Doomsday discourse. Speculation rolled in with tidal force, fueled by memories of Wakanda Forever and the uneasy silence surrounding Talokan’s king.

Namor the Sub-Mariner remains Marvel’s most mercurial monarch: a mutant ruler balancing ancient grudges, geopolitical strategy, and raw power. From declaring war on surface alliances to manipulating multiversal threats, his history proves he rarely chooses the predictable path, especially when provoked.

Together, these five fan theories feel uncannily perfect, echoing Namor’s volatile legacy while aligning seamlessly with the high-stakes chaos promised by Avengers: Doomsday.

The theory positions Shuri as the rare strategist willing to invite controlled danger into an already doomed room. Recruiting Namor is not diplomacy but deterrence. Avengers: Doomsday demands forces that frighten even allies, and Talokan’s ruler fits that requirement uncomfortably well.

Black Panther: Wakanda Forever ended with an alliance built on necessity rather than trust. Namor openly framed Talokan as Wakanda’s future insurance policy, not its friend. That line now reads less like foreshadowing and more like a contractual obligation waiting to be enforced.

Letitia Wright’s post about the Black Panther Doomwar comic did not feel accidental. In that storyline, Doctor Doom targets Wakanda’s vibranium while Shuri answers with intellect over brute force. Translating that dynamic to the Marvel Cinematic Universe places Namor as the weapon Shuri deploys, not controls.

Doctor Doom represents a threat that erases borders, oceans included. Talokan survives through isolation, not submission. An alliance led by Shuri and enforced by Namor becomes less about heroism and more about mutually assured devastation, which feels alarmingly appropriate for Avengers: Doomsday, whose synopsis confirmed everything that fans feared about Doctor Doom.

This theory imagines Namor not as a visiting menace but as a ruler without a throne. Exile reframes him from sovereign threat to displaced power. Avengers: Doomsday thrives on broken kings seeking relevance, and Talokan’s monarch fits disturbingly well.

Marvel Comics already tested this transformation decades ago. After losing Atlantis, Namor accepted Avengers membership under Captain America’s moral supervision. That arc recast fury as purpose, suggesting the Marvel Cinematic Universe could weaponize exile as character rehabilitation rather than punishment.

Black Panther: Wakanda Forever quietly plants the seeds of rebellion. Namora’s visible dissatisfaction with Namor’s surface alliance signals ideological fracture. Talokan values purity over compromise, and kings who choose diplomacy often discover loyalty has an expiration date.

Stripped of kingdom and pride, Namor would require a new battlefield. Doctor associate Doom offers that opportunity. Fighting alongside the Avengers becomes less redemption and more survival, transforming Namor from a volatile outsider into an indispensable, perpetually irritated teammate.

The theory that Namor allies with Doctor Doom rests on precedent, not shock value. Avengers: Doomsday demands morally flexible alliances, and Namor has always prioritized sovereignty over virtue. Partnering with Doom reflects calculation, not corruption, especially when survival outweighs principle.

Marvel Comics repeatedly pairs Namor and Doctor Doom when their interests overlap. From their first alliance against the Fantastic Four to Namor joining the Cabal after Atlantis fell, their cooperation is transactional. Doom even offered refuge when others abandoned Namor, forging reluctant loyalty.

The Marvel Cinematic Universe introduced Namor as a ruler motivated by preservation. Black Panther: Wakanda Forever framed him as pragmatic, not cruel. Doom offering Talokan security would appeal to Namor’s priorities, even if the partnership feels morally radioactive.

These partnerships never last. Doctor Doom manipulates, Namor resents control, and betrayal would follow. Avengers: Doomsday could use this inevitability to pivot Namor back toward the Avengers, weaponizing his anger against the very ally he once trusted.

The theory proposes Namor and Doctor Stephen Strange reviving the Defenders in comic-accurate form. Their partnership would echo Marvel Feature #1, where Strange, Namor, and the Hulk united without formal allegiance, assembling only when conventional hero structures proved insufficient.

Unlike the Avengers, the Defenders functioned as a deliberate non-team. Doctor Stephen Strange acted as a reluctant organizer, while Namor and the Hulk served as volatile allies. Their cooperation depended on necessity, not loyalty, making the group unstable but uniquely effective.

Avengers: Doomsday could provide the catalyst by forcing Strange into Talokan in pursuit of a mystical solution to Doctor Doom. Working alongside Namor would reveal a shared pragmatism, forming an alliance that operates beyond political borders and institutional heroism.

This theory aligns naturally with Namor’s anti-hero identity and Strange’s role as Earth’s mystical custodian. A Defenders revival preserves Namor’s independence while honoring comic tradition, offering a third path distinct from Avengers membership or mutant alignment.

The most probable theory places Namor alongside the X-Men, grounded firmly in textual confirmation rather than implication. Black Panther: Wakanda Forever explicitly identifies Namor as a mutant, making him the Marvel Cinematic Universe’s first in-universe bearer of the X-gene.

Marvel Comics history reinforces this positioning. Namor is publishing history’s first mutant and has repeatedly aligned with the X-Men. Both Charles Xavier and Erik Lehnsherr sought his loyalty, and Namor formally joined the mutant cause during Avengers vs. X-Men.

Talokan’s isolation mirrors mutant persecution with aquatic flair. Namor understands secrecy, fear, and preemptive aggression. The X-Men offer alignment without obedience, a philosophy that suits a king who believes compromise should always feel uncomfortable.

As Avengers: Doomsday reshapes alliances, this theory lands cleanly and conclusively. Namor belongs with mutants, not committees. It is the most faithful outcome, the most narratively sound, and the only ending that feels less like speculation and more like destiny.
