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.
He exhibits the same strength effortlessly and yet still has more room for growth. At this point, he hasn't ever needed to use his full power, whereas Goku frequently needs to reach his limits. All in all, Saitama wins this competition.
Deus ex machina is the most powerful character in Future Diary. He is known as the ruler of Time and Space. His control over these domains allows him to create the Future Diaries. Due to his ability to warp reality, he can defeat Ultra Instinct Goku as easily as Featherine.
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.
With Ultra Instinct, master or not, Goku could evade all of Saitama's attacks leaving his prodigious, signature ability completely useless.
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 (1000 IQ) VS 1.000. 000 Colossal Titans: 1.000 IQ, 100 IQ, 10 IQ!
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 has his transformations and innate Saiyan traits. On the other hand, Saitama has overwhelming raw strength that, so far, surpasses anything that Saiyans can do.
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.
Goku may never pass Zeno and 4 other Dragon Ball characters
While his fight with Moro showed he can beat another Ultra Instinct user, Whis' Angelic heritage and proficiency is unfathomable.
Super Saiyan 3 Goku at full power has a battle power of 24,000,000,000, 2 billion above Kid Buu's level.
With the snap of a finger, Zeno is capable of erasing entire universes from existence, so regardless of Goku's Saiyan abilities, his mortal constraints will almost certainly prevent him from overpowering Zeno.
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.
Going by the facts offered by the last chapter, it can be argued that Goku has fought against opponents with equal or more strength than Saitama's in Dragon Ball's history. So a single Serious Punch from the bald hero would not be enough to destroy him as of yet.
In the OPM web comic, it is stated by the infamous Dr. Genus, that Saitama has "removed his limiter." Even though Saitama is a human, he has surpassed his limiter to getting stronger, while Goku still has that. As a Saiyan, Goku has a very, very big limiter.
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.
Finally, Genos's death gave the hero the push he needed to show what he was truly capable of. Debuting the Killer moves in his Serious Series, the past few chapters have shown that Saitama's strength is at least planetary level and possibly universal.
Goku's power level at the first rank of Super Saiyan blows Deku's cowling away already granting Goku about 5o times his base power and with no real risk to Goku's body.
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 from One Punch Man is the strongest character in anime, period. Even with new anime launching all the time, no one can hold a candle to him, because he's designed around the concept of being the strongest.
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.
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.
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.
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).
