Namor and Aquaman share many of the same strengths and abilities. As well as them both being able to breathe underwater and manipulate water, the two heroes also have superhuman strength, speed, and endurance. Namor and Aquaman have had instances of immense power in their respective comics, but Namor has the edge.
While in his element, Namor is able to trade blows with beings as powerful as the Hulk, clearly making him much more formidable than DC's underwater hero. Namor has the ability to fly, which his DC counterpart lacks entirety. It should be noted, however, that Aquaman no longer has any weaknesses in modern comics.
This makes Animal Man one of the most formidable heroes around and will allow him to beat Namor. If Namor takes the fight under water, he'll soon discover he doesn't have the advantage he thinks he does. Animal Man can regenerate and heal himself from injury by tapping into insect and reptile abilities.
Namor has two consecutive defeats in the Secret Empire storyline. First, he is defeated by Hydra forces, which destroy an Atlantean temple and force him to hand over a Cosmic Cube shard. Then, Namor's own people turn on him after he becomes a tyrant in order to protect them from the Hydra government.
MCU Namor was stated by the authors to be on par with hulk and thor in terms of strenght. To clarify this, the director said he's as strong as Thor out of water and as strong as Hulk in water.
However, while one might assume the Hulk's strength was too much for Namor to handle, Marvel's first mutant has actually beaten the Hulk in a fight before - more than once.
Though his successor, Shuri, eventually managed to defeat Namor, T'Challa likely would have had the battle better in hand than his sister did. T'Challa was ultimately more experienced than Shuri, giving him an extra edge in battle, even against the likes of Namor.
When he is short on water, Namor's strength, stamina, and durability are significantly affected, which makes him considerably weaker and more vulnerable to attacks.
Superman beats Namor in every possible category. Superman is several levels above namor in raw power. NO MATTER WHETHER NAMOR IS IN THE WATER OR NOT. Superman is easily one of the most powerful beings in the universe.
Aquaman has a known speed of around 7K mph and a top speed of 50K miles per hour. Namor is not know for his swimming speed as much as his flying speed and his strength. While he is quite possibly the fastest in Marvel it is without a doubt that Aquaman is the fastest in DC with a speed of Mach 65 in one hour.
Namor's origin is slightly different from the comics, in that both of his parents are human, and his underwater abilities came from the plant his mother ingested while pregnant. His mutant gene also, as stated by Namor, endowed him with wings on his ankles and his pointed ears.
As for Namor he has always been bullet proof, knife proof, tank proof etc. since the very beginning. In fact very few things can hurt him or even pierce his skin. He has used his body as a weapon to go through any form of rock and steel and is very strong.
I think Namor wrecks unless he is all dried out. Super experienced superman with vibranium stuff and killer state of mind beats novice superman with swingy webs. Namor just seems to be ~a tier above Spider-Man.
If Namor has an arch-villain, it is probably Attuma, a fellow Atlantean and ruthless warlord. He believes himself destined to conquer Atlantis, and he has attempted it on several occasions, succeeding more than once.
However, a side-effect of the herb required them to make their nation of Talokan in the ocean, and it seems likely that the shift from more natural skin tones to blue when out of the water comes from a lack of oxygen absorption through the skin when Namor's people come to the surface.
Namor was alive and active during Infinity War, but he also needed to keep his kingdom a secret from the surface world. He didn't care if the entire planet burned as long as Talokan remained intact. My best guess is that Namor didn't know what Thanos was trying to do.
With his claws possible assuming they were knocked out before he attempted to kill them he could. He likely couldn't kill a conscious Namor or Aquaman because they are just that much faster and stronger than him.
The Silver Surfer struck back and Namor knocked him down again. The two of them went back and forth striking blows until Namor finally convinced The Silver Surface to forfeit and assist him in destroying the device.
According to the actor who is playing Namor: “Namor is as strong as Thor.” “And if there is enough water nearby, he can be as strong as the Hulk.” Ryan Coogler confirms that #Namor is as strong as Thor & the Hulk.
Namor nearly overwhelms Scarlet Witch as he blasts her with Phoenix fire, but she taps into all of the magic available to her and uses her magic not only to block the fire but as a forcefield to ricochet the fire back at Namor. Namor is consumed by the Phoenix Fire and plummets to the ground.
Marvel Studios' Assembled: The Making of Black Panther: Wakanda Forever saw fight coordinator Aaron Toney explain why the Black Panther had to damage Namor's ankle wings in the movie. According to Toney, the decision was made to humanize Namor in his fight with Shuri — and the wings will grow back in the MCU.
