Namor is the king of all that he surveys (so long as it's deep underwater). Born from the marriage of a sea captain and an emperor's daughter, Namor is the king of Atlantis. Marvel's very first mutant, he is also capable of flight and he's practically unmatched as a fighter when in the seas. He's also crazy, crazy strong. How strong? In Avengers #3, he knocked The Hulk out in no time at all. And that's not the only time they've fought or the only time that Namor has won, either. True, he's had a tougher time over the years as The Hulk's power level has slowly risen but odds are still good that the Submariner could lay the smash-down when called on.
