Son of Leonard McKenzie, Captain of a U.S. Ice Breaker, and Princess Fen of the Royal House of Atlantis, Namor McKenzie (also known as the Sub-Mariner, the Avenging Son of Atlantis, and Subby) has been both beloved and reviled by Humans and Atlantians alike.
He is a rare hybrid endowed with great strength, power over the undersea world, the ability to breathe both in and out of water, and the gift of flight. He fought valiantly with the Allies in both the Atlantic and Pacific during World War II. He has been King of Atlantis at times and the C.E.O. of Oracle, Inc. at others, but he has also been exiled from his undersea homeland as a traitor and hunted by the Avengers and the Fantastic Four as a criminal. His adventures span more than 60 years of history.
