Thanos has the infinity gauntlet with all six
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. The only question in this fight would be "how many times would Saitama have to punch Thanos to win?"
Let's say Saitama knew about the Infinity Gauntlet's powers, and had to go for the kill ASAP. Saitama would knock Thanos down the second he got the infinity gauntlet. Thanos would need to stand back up, and when Saitama is about to punch Thanos, Thanos would try to raise his fist to block it.
Yes he can. As long as speed is unequalized, then saitama can blitz the infinity barrier.
Saitama would stand no chance against Gojo and his infinity. He could keep punching the Jujutsu Sorcerer but it would be of no avail due to the infinite pocket of space between them. Gojo can also use his domain expansion to end the fight by immobilizing the hero.
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.
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.
It is true that we have not seen Saitama's full power, and his fight with the God of his universe is fast approaching, but until we see him at his full potential, it is clear that Saitama is no match for Zeno now.
At one point, the protagonist of One Punch Man even slapped himself. While he gave himself a huge red mark, he seemed mostly unaffected by it, which suggests that he could likely withstand his own punch as well.
The more popular theory in the fandom suggests that, like Hulk, Saitama will be able to lift Mjolnir because of his brute strength, and not because he is worthy. In the One Punch Man universe, Saitama is by far the strongest being who surpassed his limit breaker a long time ago.
Saitama could defeat Deadpool with one punch, but then Deadpool would heal and come back to life.
A key advantage that Hulk has over Saitama is his ability to heal/regenerate himself. Hulk has one of the strongest healing factors in all of Marvel, rivaling even Wolverine's ability to heal. This is not a power that Saitama is ever shown to have.
He would find he can't lift it. At best Saitama has demonstrated planetary levels of strength with ease. However, Mjolnir is not something you can lift via strength.
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.
He seems to attract monsters left and right and then receives credit for their defeat after other heroes, primarily Saitama, has defeated the monsters. So, regardless of his reputation, he's just a normal human and thus is no match for Iron Man.
According to Saitama, he achieved immense strength by performing 100 push-ups, 100 squats, 100 sit-ups, and running 10 kilometers daily for about a year. Genos hears this and doubts the credibility of Saitama's explanations, suggesting that the routine isn't stressful.
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.
4) Saitama (One Punch Man)
Saitama may be the least-known hero in his own series, but he is known in all anime and manga as perhaps the only character who can beat Goku. The Avengers do not stand a chance against him.
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.
[ Still trying to do the math on how, the only thing to ever actually damage Saitama in the series is a cat scratching his face.
Boros is the strongest villain in the One Punch Man series so far. He was one of the few characters acknowledged by the Caped Baldy as a strong fighter. Boros' latent energy is so high that he can blow away planets. During this fight, he sent Saitama to the moon, showing just how strong he was.
Boros is credited with being the strongest opponent Saitama has ever fought. Not only was he able to survive multiple punches from Saitama, but he was also strong enough to kick him to the moon and even put his body back together after Saitama literally punched him to pieces.
