It is certain that most heroes from One Punch Man, especially Saitama, would likely stand out due to their incredible strength in Marvel Comics. Saitama might even rank among the most powerful characters. Saitama’s ability to end fights with just one punch makes him seem invincible against many threats.
However, he could run into difficulties when facing cosmic entities or beings with reality-altering abilities, which are common in Marvel stories. Generally, these heroes would appear far stronger than most, taking down enemies that usually require the combined efforts of Avengers.

How One Punch Man Characters Would Compare in Marvel
Saitama: Recognized as the most powerful in his universe, Saitama would likely surpass figures like Thanos or the Hulk. His unmatched strength allows him to defeat almost any foe with minimal effort. However, his abilities might not be enough against cosmic forces such as the Living Tribunal or beings capable of altering reality.
Genos: With his advanced cybernetic body and high-energy attacks, Genos could be viewed as a top-tier hero, comparable to Iron Man or Vision. Even with his formidable abilities, he may still fall short against the strongest figures in Marvel, placing him in the middle tier of powerful characters.
Bang and Fubuki: Both of these heroes have exceptional skills, but they wouldn’t be among the most dominant in Marvel. Bang’s mastery of martial arts and Fubuki’s psychic abilities make them formidable, but they would not match the sheer strength of Marvel’s strongest superheroes.
King: His reputation as an all-powerful warrior would likely carry over into Marvel, much like in his own world. While he is feared for his supposed abilities, in reality, he lacks actual combat power. This could lead to situations where he is mistakenly relied upon for battles far beyond his capability.
Possible Issues and Challenges
Lack of Real Competition: With Saitama being stronger than almost anyone, most Marvel villains would likely fail to challenge him, making fights uninteresting for him. This could lead to frustration as he struggles to find an opponent worth his time.
Doubt and Distrust: A hero as overwhelmingly powerful as Saitama might initially face suspicion from Marvel’s superheroes. His unmatched strength could raise concerns until they fully understand his true nature and motives.
Dealing with Cosmic-Level Threats: Even with all his power, Saitama could face difficulties against Marvel’s reality-altering entities. Beings that manipulate existence itself might pose a challenge, as their abilities go beyond brute strength.
