The Sub-Mariner

From: toonarific.com
The Marvel Superheroes consisted of five different segments, each starring a well-known superhero from a particular Marvel comic - The Sub-Mariner, Captain America, The Incredible Hulk, Iron Man, and Thor.

"The Sub-Mariner" was the title given by surface dwellers to Prince Namor of Atlantis, a half-human, half-Atlantean. More anti-hero than superhero, Namor hated all surface-dwellers regardless of who they were. As luck would have it, the moody prince often found himself fighting against polluters or other villains who wanted to hurt his underwater home as well as the innocents on land. Blessed with super-strength and the ability to fly using wings attached to his feet, The Sub-Mariner would repel any threat to Atlantis and usually ended up helping the “land-lubbers” he so disdained.
