Zeno from Dragon Ball Super couldn't just defeat Saitama but could put an end to everyone in the One Punch Man universe. He is the god of the multiverse and is so strong that he can wipe out the entire universe with a single thought. If Saitama infuriates Zeno, he can kill him without even raising his hand.
Both the narrator and Garou mentioned that Saitama has limitless potential, and despite the lack of challenge, he is constantly growing. This means that even if someone is strong enough to possibly push Saitama to his limits, the Caped Baldy will surpass it and proceed to defeat his opponent.
Being a supernatural deity, Rimuru is immune to any kind of physical attack, so Saitama's punches are a no-go. Moreover, destroying his physical body won't kill him unless his core is destroyed, that is, his soul. Until Saitama uses some special magic spell, he cannot defeat Rimuru.
Shonen Jump heroes are generally known for their ridiculous strength; however, One-Punch Man's Saitama is on a completely different level. Renowned for being able to end almost any fight in one punch, he just might be able to defeat Naruto — or any other shonen protagonist — in a one-on-one fight.
This matchup is too close to decide with absolute certainty, but, in all likelihood, Saitama would claim victory. The fight would ultimately come down to who can last the longest, and Saitama is physically unmatched in every regard. A single punch would floor Goku, but the Zenkai Boost may not be enough to help.
Goku wins this. Sure, Goku risky fighting style may lead Saitama to outpace him from time to time - but Goku has just that much raw power that Saitama simply lacks. Not to mention, we know he's smart enough to use his highest Kaiohken in a last burst, since it's exactly what he did against Frieza.
A leading fan theory regarding the source of Saitama and most characters' strengths is that they trained and dedicated themselves to an inhuman level. The result of their high-level dedication is supernormal strength that is unusual for a human. In fact, many heroes in One-Punch Man can be linked to this theory.
In a battle against Hulk, every little bit counts. Saitama having this ability provides him a slight edge, as he effectively has a source of projectile attacks that he can use at a distance.
Thus, it is safe to say that Limit-breaker Saitama cannot beat Goku in his Ultra Instinct form. It is far too powerful a transformation to contend with. Even if Bald Cape lands his Zero Punch, Goku has been seen multiple times being more than capable of taking a hit.
3) Kakashi
But his moves like Chidori, Raikiri, Kamui, or the ability to copy his opponents wouldn't work on Saitama at all. In fact, the shinobi's low chakra reserve is a major weakness for him. If Saitama used his sneeze against Kakashi, the latter would be defeated in seconds.
Baraggan Louisenbairn is one of the major antagonists of the famous anime, Bleach. He is an Arrancar of Aizen's army, and his immense spiritual powers can easily defeat Saitama. The deadliest ability he can use against Saitama is Senescencia, with which he can slow time near him.
Boros. Boros was the first on-screen opponent of Saitama that survived after getting punched, much to his surprise. In his fight with Saitama, Boros was hit with 3 normal punches, a Consecutive Normal Punches attack, as well as the shockwave from the hero's Serious Punch.
If we calculate this distance over time, Saitama speed comes up at 150 9236 miles per second, which is quite close to the speed of light. It's safe to assume that he merely jumped. with no charging up, which means he can be faster. In short, Saitama can travel at the speed of light.
With each hit Vegeta takes, his power increases by unleashing his emotional controls and letting him lean into the fight. The advantage of Ultra Ego against Saitama is that not only would it allow Vegeta to take Saitama's signature punch, but will make him stronger as a result.
Immeasurable Strength: Saitama possesses an immeasurable amount strength and as a result is capable of destroying powerful monsters and villains with a single one punch (though this strength is not limited to punches).
Saitama (One Punch Man)
Saitama's strength and speed far outstrip even the Mad Titan's own, and these abilities would allow Saitama to easily overcome Thanos's regenerative abilities.
By his current feats, Saitama doesn't stand a chance against the Beyonder. I doubt even his full strength will be enough. Who is the strongest Marvel Comics character Saitama (One Punch Man) could defeat? Saitama is powerful enough to defeat any Marvel character who is planetary or below.
In the end, unless Clark is capable of defeating Saitama in the early stages of their fight, Saitama will be the clear victor. Not only does his limitless potential help him surpass Clark's power, but he could also last longer in combat.
Saitama. The title protagonist, Saitama (サイタマ), is a bald-headed 25-year-old man who is bored of fighting because he is able to effortlessly defeat enemies with a single punch. He lives in an apartment in City Z.
The character referred to as “God” in One-Punch man is an otherworldly being that appears to grant people power but at great cost. The well-drawn character has made its appearance in different chapters in the manga, puzzling fans on the true nature & goal of this being.
Saitama pushed himself and worked out everyday for about three years, which also led to hair loss. Apparently this endurance training was the reason for his strength. Genos found this hard to believe, because a training routine such as this would not yield such results.
