Namor's powers and abilities
Mutant/Atlantean Physiology: Namor's powers come from his being a unique hybrid of Atlantean Homo mermanus and mutant Homo superior physiologies. Because of his unusual genetic heritage, Namor is unique among both ordinary humans and Atlanteans; he is sometimes referred to as "Marvel's first mutant," because, while the majority of his observed superhuman powers come from the fact that he's a hybrid of Human and Atlantean DNA, his ability to fly can't be explained by either side (Atlanteans are an off-shoot of "baseline" humanity).
Amphibious Physiological Adaptation
Namor's body is specially developed for underwater conditions, granting him specialized blood circulation to withstand freezing temperatures and highly developed vision to see clearly even in murky ocean depths. This hybrid physiology means he can survive indefinitely underwater or on land, though he would still need occasional contact with water to survive.
Like all Atlanteans, Namor is superhumanly strong but his physical strength is greater than that of any member of his superhuman race. The exact level of his strength is dependent upon his physical contact with water and his strength diminishes slowly the longer he is out of contact with it. Out of the water, Namor was able to defeat Luke Cage with ease, and use his body as a club to knock out the She-Hulk by striking her by surprise from behind. He was shown as an even match for the Thing in the same issue. Under water, he battered the Red Hulk and stopped him from getting to the surface until he threw him out. Namor has in an occasion even knocked out the Savage Hulk. He was also able to hold his own against the Sentry for a little while, but Emma Frost mentally convinced the Sentry to stop, since Namor couldn't win. He has been seen several times lifting thousands of tons without effort. Namor has once swam against a temporal storm for a brief period, even pressing on despite getting dehydrated by that act. Furthermore his physical prowess is so great that he has been referred to as one of the most powerful beings on the planet.
Namor can run and move at speeds greater than even the finest human athlete. His speed is greatest, however, while swimming. Whereas most Atlanteans can swim at speeds greater than 60 miles per hour, Namor has shown that he can reach a speed of over 300 knots.
Namor's advanced musculature produces considerably less fatigue toxins during physical activity than the musculature of normal human beings, and most other Atlanteans for that matter. At his peak, Namor can physically exert himself for at least more than 24 hours before the build up of fatigue toxins in his blood begins to impair him. Namor's stamina, much like his strength, steadily declines the longer he is out of contact with water and will diminish to the point where he only has slightly greater stamina than the finest human athlete.
Namor's agility, balance, and bodily coordination are enhanced to levels that are beyond the natural physical limits of even the finest human athlete. He can perform acrobatic feats in the air sufficient to enable him to easily evade/dodge most military aircraft.
Namor's reflexes are similarly heightened and are superior to those of the finest human athlete since he can react at impressive levels of super speed-as demonstrated through his catching missiles and throwing them back at their point of origin.
The tissues of Namor's body are much harder and more resistant to physical injury than those of normal human beings and most other Atlanteans. Namor can withstand tremendous impact forces, high caliber bullets, falls from orbital heights, exposure to temperature and pressure extremes, blows from powerful superhumans and powerful energy blasts without sustaining injury.
If he was somehow injured, Namor's body can heal damaged tissue faster and much more extensively than a human or most Atlanteans. Namor's accelerated healing is at it's peak while he is immersed in water and does diminish the longer he is out of contact with water or if he is completely dry.
Namor can absorb certain levels of radiation. His potential is unknown, but the full power of the Radioactive Man is enough to rapidly drain him of his strength.
Atlanteans age much slower and live much longer than human beings with the average Atlantean lifespan being about 120 years. Namor, at this time, is considered to be in his physical prime.
Like all Atlanteans, Namor can breathe indefinitely underwater due to having gills located behind his ears. Unlike most Atlanteans, however, Namor can also breathe on land indefinitely as well without the aid of breathing devices whereas most Atlanteans can only survive being out of the water for a matter of minutes.
Namor possesses a telepathic rapport with all forms of marine life. He is able to mentally communicate with most forms of marine life and can mentally persuade them to do his bidding. Namor can also mentally communicate with other Atlanteans (giving mental-telepathic orders to all his men) and probably Humans as well.
Namor's enhanced vision enables him to penetrate the ocean's depths and see through murky water.
Namor also possesses vestigial "wings" on both of his ankles, by which he seems to fly at the speed of escape velocity when exerting himself fully. His flight speed at "normal" levels is enough to enable Namor to fly faster than military aircraft. Since the "wings" by themselves could never carry Namor, it has been speculated that he uses the wings for steering and flies in some other manner, perhaps by telekinesis. Namor's ability to lift weights when flying is sufficient to enable him carry a fifty ton anchor with one hand without a discernible loss of speed/momentum.
Namor's extended lifespan and his involvement in numerous conflicts both under the sea and in human wars have granted him a great deal of experience in hand to hand combat. Growing up, he demonstrated natural skill in both armed and unarmed combat and likely received extensive training in both later on. He is a master swordsman, marksman, and is capable of wielding other weapons such as spears but rarely does so due to his preference of hand to hand combat.
Namor is also a highly skilled leader and capable ruler.
As the leader of a sovereign nation, He often visits the United States or the United Nations for political reasons. He enjoys diplomatic immunity during these trips.
He is a highly accomplished tactician.
Namor speaks virtually every language on Earth.
He is adept at designing and improving Atlantean technology.
