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 sheer untapped power of Saitama from One-Punch Man beats Dragon Ball's Goku in terms of strength. There are two names repeatedly brought up when discussing the most powerful anime characters.
With Ultra Instinct, master or not, Goku could evade all of Saitama's attacks leaving his prodigious, signature ability completely useless.
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.
Saitama (1000 IQ) VS 1.000. 000 Colossal Titans: 1.000 IQ, 100 IQ, 10 IQ!
Goku: 76, even though you might think his IQ could be even lower sometimes, he often proves he can do some smart things too, especially while fighting and especially during DBZ.
Unparalleled Strength: Saitama possesses seemingly limitless physical strength and is capable of effortlessly defeating powerful monsters and villains with a single, casual punch (although this strength is not limited to punches). His punches are so powerful that many monsters simply explode when struck.
6 Light Yagami (Death Note)
Sometimes the best battle fought is one that isn't fought at all. Light Yagami's Death Note is the ultimate weapon he has with him. Basically, all he has to do is lift his fingers, jot down Saitama's name, and Saitama would be dead.
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 fight wouldn't last a second let alone enough time for Goku to transform into a Super Saiyan.
Saitama is also theoretically much faster than even the Zero Causality Fist, as it appeared to cause him no strain or fatigue when using it, implying even this isn't his maximum speed. Though Goku may be one of manga's most iconic powerhouses, One-Punch Man's Saitama is closing the distance with every chapter.
Secondly, some people claim that the writer of OPM(One) has said that the limit of Saitama's power is that he can destroy half a universe with one full-powered punch. This isn't true. One has never said anything like that, and it is only a rumor.
Goku has multiple fusions that he could use in battle against Saitama. Examples of his fusions include Gogeta, Vegito, and Den-Goku. These fusions would give him the added abilities of his allies, including Vegeta and Dende, and this could help give him the leg-up in battle when fighting someone as tough as Saitama.
There is about a 1% Saitama will ever beat Goku even when high balling. Saitama (One Punch Man) has beaten almost all of his opponents with one hit however when you look at the scaling of everyone there it's not hard.
If Saitama trained the same way Goku did he would become the absolute most powerful being in fiction far above anyone in dragonball possibly even Zeno and that is no exaggeration. He would literally “one punch” everyone.
Goku. Goku is the main protagonist of the Dragon Ball franchise. His abilities include super strength, utilization of ki, teleportation, super speed, and durability. However, he is the strongest anime character because he overcomes adversity and thrives on improvement.
Saitama Beats God and Destroys the Universe.
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.
Lord Boros is the mirror antagonist to Saitama. Like Saitama, he was too powerful to find a worthy opponent and became extremely bored. Boros serves as a reminder of what Saitama could be if he didn't have a heroic foundation.
This comes from Saitama's rigorous, albeit simple, work-out regimen. Indeed, he's withstood the best that his opponents have given him, and rarely comes away with a scratch. Accordingly, there is no evidence suggesting that he would be physically unable to withstand even his own attack in One-Punch Man.
The origin of Saitama's immeasurable power remains mysterious and unclear. Although he tells everyone he got his incredible power through mere physical training, no one believes him at all.
The force required to hold something against gravity, or lifting, is calculated using the formula m (mass in kilograms) x g (gravity force, 9.8). To lift that air carrier, Saitama would then produce 882 million joules of force.
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.
