The question of whether Goku or Saitama is stronger is a complex one, debated extensively by fans of both Dragon Ball and One-Punch Man. Different sources present conflicting conclusions.
Some sources claim Saitama is stronger. This argument centers around Saitama's defining trait: he defeats any opponent with a single punch. The implication is that his power is limitless and transcends conventional power scaling. One source even states, "Saitama would easily win" in a one-on-one fight. [Reference: 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.] This perspective emphasizes Saitama's unparalleled ability to defeat any opponent regardless of their strength.
Conversely, other sources argue for Goku's superiority. These arguments highlight Goku's vast feats of strength, speed, and ki manipulation, demonstrated throughout the Dragon Ball series. For example, one source points to Goku's raw power, suggesting it would ultimately overcome Saitama. [Reference: Jan 9, 2023 ... 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… ] Furthermore, arguments are made that Goku's ability to consistently surpass his limits through training makes him potentially stronger.
Ultimately, the answer depends on the interpretation of the characters' powers and the limitations placed on the comparison. The nature of Saitama's power, intended to be limitless and a humorous subversion of typical battle shonen tropes, makes a direct comparison problematic. One source summarizes the debate as "useless," highlighting the inherent subjectivity involved. [Reference: Goku vs Saitama is the most useless debate of all time.] Several sources emphasize that Goku has demonstrated feats of strength on a universal or even multiversal scale, which some argue makes him undeniably superior. [Reference: So Goku is Universal to Universal + (Low-Ball) Low-Multiversal when scaled properly Multiversal (High-Ball) So No, Goku is stronger than Saitama]
In conclusion, there's no definitive answer. The debate hinges on interpretations of narrative intent and power scaling methodologies that aren't directly comparable.
