Sub-Mariner

Powers
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.


 * Superhuman Strength: 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.[70] Underwater, he battered the Red Hulk and stopped him from getting to the surface until he threw him out.[71] Namor has on occasion even knocked out the Savage Hulk.[19][72] 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.[73] 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.[74]Furthermore, his physical prowess is so great that he has been referred to as one of the most powerful beings on the planet.[75]


 * Superhuman Speed: 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,[76] Namor has shown that he can reach a speed of over 300 knots or 345 mph.[77]


 * Superhuman Stamina: 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.


 * Superhuman Agility: 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.


 * Superhuman Reflexes: 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.


 * Superhuman Durability: 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.


 * Aquatic Healing: 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 its peak while he is immersed in water, but does diminish the longer he is out of contact with water or if he is completely dry.


 * Radiation Absorption: 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.


 * Extended Longevity: 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.


 * Underwater Breathing: 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.


 * Aquatic Telepathy: 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[78]) and possibly humans as well, should he develop his power to its fullest.[79]

Augmented Vision: Namor's enhanced vision enables him to penetrate the ocean's depths and see through murky water.
 * Electrolocation: Like some fish, Namor has a limited ability to navigate by sensing faint electrical currents within the water.[76]

Flight: 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 50-ton anchor with one hand without a discernible loss of speed/momentum.

Hydrokinesis: After siphoning off some of the power of Hydro-Man, Namor gained hydrokinetic powers.[79] He wields enough to power to part a large section of water with ease.[78]

Aquatic Life Mimicry: The Sub-Mariner has the ability to mimic the characteristics of all the undersea creatures. Some of the abilities he has demonstrated are:
 * Sonar: Namor possesses a natural form of sonar
 * Hybrid Sense: He can follow radio beams.[84]
 * Lateral Lines: Namor can detect subtle movement or vibrations around him, particularly underwater.
 * Bioelectricity: Namor can discharge bio-electricity similar to an electric eel, but seldom uses it. He seems to be able to absorb certain energies and convert them into bio-electricity; blasts similar to his own such as from the Wasp seem easiest to absorb. It would appear that he needs to absorb energy from outside sources to produce a charge.

Abilities
Expert Combatant: 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.

Bold Diplomat: Namor is also a highly skilled leader and capable ruler.

Diplomatic Immunity: 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.

Expert Tactician He is a highly accomplished tactician.

Multilingual: Namor speaks virtually every language on Earth.

Skilled Engineer: He is adept at designing and improving Atlantean technology.

Talented Business Executive: Ever since he was a teenager, he proved to be very adept in the field of business, as it came easy to him.

Weaknesses
Due to his mingled bloodline of Atlantean and human breeding, a number of natural dependence and unique vulnerabilities has occurred.

Water Deficiency: When not exposed to water, many of Namor’s physical attributes gradually decline and can reach a point where he possesses only a small fraction of his powers. Namor's strength, stamina, and durability are affected most and, at their minimum known level, are much closer to the levels possessed by the vast majority of other Atlanteans. Renewed exposure to water will immediately restore his abilities.

Oxygen Imbalance: Namor has demonstrated a vulnerability to oxygen imbalance when remaining too long in either water or air, resulting in manic-depressive mood swings.
 * Bipolar Tendencies: Namor is believed to be in the midst of an imbalance during the times in which he becomes angry very easily, which he is well known for, and is unable to think clearly and logically. He can prevent this imbalance, however, by dividing his time between the two atmospheres. He has occasionally used scientific or magical means to regulate his oxygen levels. With the imbalance properly controlled, Namor has shown himself to be a much more capable leader and generally much easier to be in contact with.

Dehydration: Very powerful heat-based attacks are somewhat of a concern, as they cause dehydration, causing his body to dry faster, and weaken at an accelerated rate.
 * Head Problems: Though the complete circumstances are unknown, if hit just right, Namor has at times succumbed to physical head injuries very easily, such as being knocked out by a lead pipe wielded by a normal human man. This may come from oxygen imbalance or after the permanent head damage he suffered by the psychic Destiny. Still, there are times he has withstood constant high force attacks, such as the Hulk`s fist.

Pollution: If Namor is immersed in or exposed to polluted water, it can have a negative effect both on his physiology and the efficiency of his physical attributes.

Wings: Despite being incapable of providing lift, Namor's wings seem to be essential to his flying abilities, and their lose renders him grounded. These appendages seem to be slow to heal when damaged, given that after losing them, he required an extended period of time to regrow them.

Weapons
Neptune's Trident: Neptune's Trident is in part made of Enchanted-Adamantine Metal while possessing other properties which have yet to be completely revealed. The trident is capable of many things centering but not limited to water-base feats.
 * Water Manipulation - Ability to control any body of water, create water elementals, speed ships and other water vehicles with water, create fogs and storms of high intensity, summon waves of water to propel him at great speeds, and create earthquakes by increasing water pressure.


 * Mystic Beams - (Protruding from the trident) It's been constantly depicted that lights or lasers of many colors with many of their own attributes from healing, damaging, cursing and granting.


 * Mystic Formation - A unique power to transform objects, willing subjects, and even the wielder, to any desired form with added abilities.
