Powers and Abilities
The Sub-Mariner is one of the strongest mutants in the Marvel Universe being classified as a Class 100 character. When Namor is underwater his strength has been stated to be virtually unmatched. Namor is strong enough to hold his own in hand to hand combat with the Hulk, Thor as well as the Blue Marvel. He has superhuman stamina, durability, agility and speed, but his powers slowly decrease as he spends time out of the water. He can survive indefinitely in water or on land, and is able to withstand all pressure and cold in the sea. He has the durability to withstand the pressure of the depths of the ocean, extreme heat temperatures, and sonic attacks.
Although being deprived of water for long periods can make him ill and relatively weak, he once spent several years living as an amnesiac human in the Bowery region of New York after being mind wiped by Paul Destine. He can swim at torpedo-like speeds. He also has an extended lifespan being over 90 years old, yet physically still in his prime. Namor also has the ability to channel the powers of any aquatic life in the sea. For example, channeling the power of an electric eel and shooting electric bolts from his hands. He has also used radar powers like a blind fish to see Sue Storm whilst she was invisible.
All Atlantean magic flows from Namor, their king. His royal blood also is a magic ingredient that can be used in spells.
Mutant Power
Namor's mutant power are the wings on his ankles which appear to allow him to fly and his greater degree of strength. Namor was actually the first comic book character with the power of flight, already flying in his second comic book appearance in Marvel Comics #1, while all other contemporary characters like Captain Marvel, Superman and Wonder Woman only could leap great distances and didn't fly canonically until several months later.
His skin is very resistant to any physical damage, he can resist bullet fire with ease and is fireproof.
Powers and Abilities
As an immortal god, Poseidon possesses vast strength and endurance. His physical capabilities are superior to those of the majority of Olympian gods. He has virtually inexhaustible stamina, and does not tire appreciably after any exertion. Like all Olympians, Poseidon is immortal, possessing a life essence that can not be ended by any conventional means. He can be wounded in battle, but his godly life force gives him incredible recuperative abilities. He can fully recover from penetration wounds (such as by knife, sword, or bullet) in anywhere from minutes to hours, depending on their severity. Only an injury of such magnitude that it incinerates him or disperses a major portion of his bodily molecules could cause him physical death. Poseidon commands all the power of the seas, enabling him to manipulate everything from weather patterns, to whirlpools and ocean currents, to sea vegetation. He also uses his trident to fire powerful energy blasts.
