For now, the Namor rumors remain just that — rumors. As it is, we may not know whether Tenoch Heurta is portraying the Sub-Mariner until the film is released, because Marvel Studios remains quite good at keeping their secrets. They’re also likely to be extra careful about any details surrounding their “Black Panther” sequel.
Even still, there’s at least one very good reason to think “Wakanda Forever” will head into the depths of the ocean and introduce Namor, which is a very Easter eggy tease even Marvel die-hards might’ve missed in 2019’s “Avengers: Endgame.”
That tease came during Natasha Romanoff’s (Scarlett Johansson) debrief with the undusted remnants of The Avengers. During her exchange with Danai Guria’s Okoye, the Wakandan warrior informs her of an earthquake off the coast of Africa, before informing Natasha, in a rather snarky manner, that there’s not much to be done about such things. She may regret not taking a closer look at that disturbance, though, as it could possibly have signaled the arrival of Namor, the mutant son of a sailor and Atlantean princess who now holds dominion over the fabled underwater city of Atlantis.
Should that be the case, “Black Panther: Wakanda Forever” will indeed be taking Marvel fans somewhere they’ve never been. And should that casting rumor prove true, it will also introduce a beloved character who has played the part of hero, antihero, and villain in the pages of Marvel Comics over the years. We’ll just have to wait and see which version of Namor debuts in the MCU first … or even if he’ll debut at all.
