Namor is extremely strong, both in the Marvel Comics and the Marvel Cinematic Universe (MCU). In the comics, he has superhuman strength, speed, durability, agility, and reflexes. He is often described as the strongest Atlantean ever known, with strength sufficient to effortlessly toss water-filled ocean liners, lift submarines, and even hold up an island pillar. His strength is enhanced when in contact with water and he possesses great stamina and resistance to injury. Namor's abilities also include flight, telepathy, and control over marine life. He has fought beings as powerful as the Hulk and has held his own or defeated him, especially underwater. His strength on land is described as "unearthly," but it reaches superhuman levels when fully hydrated or in water. In the MCU, Namor is portrayed as one of the strongest characters, comparable in strength to both Hulk and Thor. He has shown the ability to easily overpower enemies and outclass protagonists like Shuri in physical combat. His fighting capability is bolstered by his amphibious nature, flight, and combat skill. While Namor can lose to some powerful characters, he is depicted as a high-tier powerhouse with strength rivaling major MCU heroes. Overall, Namor is one of the strongest characters in Marvel's universe, with strength exceeding nearly all humans and Atlanteans, able to match or surpass iconic figures like Hulk and Thor under the right conditions.
