Fan Casting Namor the Submariner in Marvel Studios' Avengers: Doomsday

King Ch'ah Toh Almehen, a Talokanil mutant, rules the underwater kingdom of Talokan as K'uk'ulkan, revered for his slow aging. After his mother’s death, he saw Spanish colonization’s horrors, earning the name Namor by violently opposing it. To shield Talokan from surface threats, he grew wary when the U.S. sought vibranium near his realm. Namor proposed a military alliance with Wakanda, but their refusal led him to attack, killing Ramonda. Defeated by Shuri, the new Black Panther, Namor yielded, believing Wakanda would eventually seek his aid.
