Sub-Mariner, aquatic anti-hero

Sub-Mariner first appeared publicly in Marvel Comics #1 (Oct. 1939) — the first comic book from Timely Comics, the 1930s-1940s predecessor of the company Marvel Comics. During that period, known as the Golden Age of Comic Books, the Sub-Mariner was one of Timely's top three characters, along with Captain America and the original Human Torch. The son of a human sea captain and of a princess of the mythical undersea kingdom of Atlantis, Namor possesses the super-strength and aquatic abilities of the "Homo mermanus" race. Through the years, he has been alternatively portrayed as a good-natured but short-fused superhero, or a hostile invader seeking vengeance for perceived wrongs that misguided surface-dwellers committed against his kingdom.
The first known comic book anti-hero, the Sub-Mariner has remained a historically important and relatively popular Marvel character. And soon at a theatre near you!
