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.
Shigeo Kageyama or Mob has psychic powers and is powerful beyond measure. He can destroy people with his mind alone and has defeated the strongest of opponents without much effort. Therefore it is easy for him to defeat one punch man.
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.
The mere comparison of strength between the two characters is crazy. Goku is an extraterrestrial being who has to lose a fight in order to get stronger. Saitama is a man that can defeat any foe with a single punch. If the two of them were to face off in a one-on-one battle, Saitama would easily win.
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 vs cat
[ 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.
Saitama may get full marks for putting up a good fight since he undoubtedly is stronger of the two. The problem lies with Saitama and Naruto's similar abilities: One-Punch and Rasenshuriken (wind release Jutsu), respectively. Naruto wins by virtue of his stamina and speed.
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.
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.
According to Saitama, he became strong due to his rigorous workout routine. It consisted of 100 push-ups, 100 sit-ups, 100 squats and 10 kilometers of running. Saitama pushed himself and worked out everyday for about three years, which also led to hair loss.
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.
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.
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.
The character was the holder of the Rinnegan eyes, and aided by his seemingly boundless chakra, he wreaked havoc on numerous villages causing countless deaths. Despite this, Saitama would easily defeat Pain without breaking a sweat.
Unfortunately, since Saitama cannot also elevate his strength into another form, it would be unfair to compare Super Saiyan Goku to base Saitama. In terms of base form strength, Saitama from One Punch man takes home the win against Goku.
Saitama, also known by his hero name Caped Baldy, and also as One Punch Man, is the titular protagonist of the webcomic/manga/anime series One Punch-Man, and the most powerful known being in the series.
Saitama has yet to lose any battle on screen, but in the manga so far there's been three opponents that Saitama has used more than a Normal Punch against. Beast King is very easy to write off, because he wasn't actually that strong.
Saitama is incredibly powerful and he could decimate most Marvel characters if he saw fit, but Dr. Strange could trick him and gain victory through magical mental manipulation. If Strange subjected Saitama to a series of hallucinations, he's likely have little recourse and not know how to overcome the illusions.
The big reveal is that when Saitama finally meets him, he will put two and two together and find out that Blast is his dad. Yes, he is supposed to be an elusive character, but especially with the other stuff we know about him, this just makes sense. The writers are still setting up their fateful meeting.
Don't go for his innocent face; Rimuru Tempest is one of the strongest anime characters who can easily defeat Saitama. Saitama can handle enemies in hand-to-hand combat easily, but what about an enemy with magical powers? The list of Rimuru's powers is endless.
Another interesting theory posits that God and Saitama are, actually, the same person, due to the hero's recently revealed ability to manipulate spacetime and alter timelines.
