Sometimes hero, sometimes anti-hero, and occasionally outright villain, Namor the Sub-Mariner isn’t just one of Marvel’s most complicated characters. He’s also their first superhero. Created in 1939, Namor quickly made a strong impression thanks to his complicated back story, dramatic eyebrows, and super-short green swim trunks. And now Namor is finally joining the Marvel Cinematic Universe in Black Panther: Wakanda Forever, where he'll be played by Narcos' Tenoch Huerta. We got our first look at Namor in the Black Panther: Wakanda Forever trailer that dropped at Comic-Con, so let’s learn all about the passionate player known as the Sub-Mariner, and why he’s far more than just Marvel’s answer to Aquaman.
