Namor the Sub-Mariner is a fictional character featured in Marvel Comics, and one of the oldest superhero characters. He was created by cartoonist Bill Everett in 1939.A trademark character of Marvel during the 1940s, Namor is the son of a human sea captain and of a princess of the mythical undersea kingdom of Atlantis (Although the Underwater kingdom was left unamed until the 1960s). Possessing the super strength and aquatic abilities of an Atlantean, Namor was alternatively portrayed as a good-natured but short-fused superhero and hostile invader, seeking vengeance for wrongs misguided surface dwellers committed against his undersea kingdom. He was thus arguably the first comic book anti-hero.
Although his stature has lessened, the Sub-Mariner has remained a somewhat popular and important Marvel character.
A Sub-Mariner feature film is in development. Chris Columbus is slated to direct.
