Namor (Earth-616)

Prince Namor, the Sub-Mariner is a character appearing in Marvel Comics. The champion of the long forgotten Tenth Realm of the World Tree, known to Midgardians as Atlantis. As a Mutant Human/Atlantean hybrid, Namor is a child of two worlds, though his loyalty is generally with his fellow Atlanteans. Frequently blurring the lines between hero and villain, Namor frequently alternates between ally and enemy of the Avengers, seeing "hero" and "villain" as arbitrary distinctions.

History
During the early 20th Century, the icebreaker Oracle arrived in Antarctica searching for vibranium deposits believed to be buried beneath the glacial ice. The ship's presence attracted the attention of the Atlanteans, who found their realm threatened by the mining. While Emperor Thrakorr sought to destroy the interlopers, his daughter, Princess Fen, took it upon herself to talk to the miners in an attempt to find a peaceful solution. Leonard and Fen soon became romantically involved, but Thrakorr violently disapproved of this union. When he learned the two were planning on getting married, he sent troops, led by General Krang, to disrupt the ceremony. Leonard and Fen were separated during Krang's ambush, with each believing the other had been killed. Fen, unknowingly pregnant with Leonard's child, would give birth to a son she called Namor, which meant "avenging son" in her native language.

Namor grew up a proud, headstrong young man prone to self-righteous rages. As the surface nations prepared for World War II, Namor initially saw no distinction between the opposing sides. Mistakenly believing that the surface world was preparing to invade Atlantis, Namor attacked New York, doing battle with the original Human Torch, James Hammond. Eventually, Namor realized the Axis Powers were the true enemy, and he and the Torch joined Captain America, Destroyer, and Union Jack in an early version of the Avengers (informally nicknamed The Invaders) that battled Nazi supervillains Red Skull and Master Man.

Not long after the war ended, Namor lost his memory after a battle with telepathic supervillain Destiny. He is found in the modern era by the second Human Torch, Johnny Storm. His Atlantean physiology meant that Namor had barely aged a day, but being separated from the ocean for all that time had driven him insane. He regained his memory when Johnny, in an attempt to clean him up, inadvertently dropped him in the Hudson River.

Namor attempted to return home, only to discover that his people had migrated to one of the other realms, leaving the city little more than a deserted outpost. Angered at the prospect of being denied his birthright, Namor lashed out at the surface world. After fighting the Fantastic Four and failing to defeat them, he reinvents himself in the form of the enigmatic Professor Falton, an expert on Atlantean history. It soon became apparent that Mr. Fantastic's intellect rivaled his own - Namor also saw Richards as a rival for the affections of Susan Storm, who he saw as a good fit for Queen of his new Atlantis. While planning his revenge on the Fantastic Four, Namor encountered the Hulk and fought him to a draw. Impressed by such a worthy opponent and recognizing his anger at surface dwellers who wronged him, Namor teamed up with the Hulk and went after the Avengers, then consisting of Iron Man, Thor, Ant-Man, and Wasp. Namor initially acquitted himself well during the battle, using his elemental powers to incapacitate Iron Man and even managing to disarm Thor. But then Namor made the mistake of attempting to grab the discarded hammer and use it as a weapon. Neither he or the Hulk were worthy enough to lift it, and the shock of trying caused the Hulk to revert back to his human form of Bruce Banner and run away. Now hopelessly outmatched, Namor fled by swimming into the Atlantic.

Namor later takes on Iron Man individually during a dispute in the South Atlantic. An elderly farmer named Hiram Dobbs had been living on one of the islands, and now soldiers were trying to force him off his land. Namor, indebted to Dobbs for saving his life, took it upon himself to fight off the soldiers. Iron Man intervenes when the soldiers tell him that island is contaminated with radioactive waste, they are simply trying to evacuate the inhabitants. Namor attacks the Armored Avenger, leading to an aerial duel where they appear evenly matched, but once the fight goes underwater, Namor easily overpowers him. The Atlantean tells Iron Man he's been lied to, the soldiers are private military contractors hired by Roxxon Energy, and they are attempting to seize control of the island because it is rich in vibranium. The two join forces and attack Roxxon's forces, but the island is destroyed in the process. It is not long after this that Namor becomes an Avenger himself.

After the Kree-Skrull War, Namor is summoned to the Imperial Palace in Wakanda by Iron Man, along with Mr. Fantastic, Professor Charles Xavier, Dr. Stephen Strange, and the Inhuman leader Black Bolt. Iron Man announces they are forming a new "think tank", the Illuminati, designed to "solve problems before they begin." Black Panther - who hosted the meeting but declined membership himself - warns them to be circumspect in their power, and not to "play God" with the lives of those they are responsible for protecting, as abusing their power will cause them to be hated and feared.

When the machinations of Obadiah Stane force Tony Stark into exile and destitution, several members of the Illuminati debate whether they should help him. Namor insists that Stark should solve this problem on his own to prove that he is worthy to lead them.

Powers and Abilities
Namor's Mutant/Atlantean physiology means that he is amphibious and ages slower than normal humans. He is capable of flight, with his ankle wings providing him a degree of balance in the air, similar to antennae. He possesses superhuman strength, speed, and durability in and out of water, though he is stronger in water: On land he is evenly matched with the likes of Thor or the Hulk... under water he can actually beat them. He has a genius level intellect, and has shown himself to be a highly skilled businessman when negotiating with leaders of the surface world.

Weaknesses
Although Namor is amphibious, being away from the water for too long causes him to suffer from dehydration. He is also implied to have post-traumatic stress disorder from his experiences in World War II.
