Namor, the Sub-Mariner, is one of Marvel Comics' earliest superheroes, first appearing in 1939. Born to an Atlantean mother and a human father, he is the prince of Atlantis. His unique heritage grants him extraordinary powers, setting him apart from both humans and fellow Atlanteans. Over the decades, Namor has evolved from a villainous character, often at odds with surface world heroes like the Human Torch, into a more complex figure balancing his duties as a ruler with his personal beliefs. He has had numerous notable storylines that delve into environmental issues, the politics of power, and the dichotomy between land and sea. His appearances span across comics, animated series, and films, making him a central figure within the Marvel Universe, especially regarding stories involving the Avengers and Defenders. With his indomitable spirit and fierce loyalty to Atlantis, Namor remains a pivotal part of Marvel's rich tapestry of characters.
