In my opinion, it's highly unlikely. Goku has mastered multiple forms and techniques that give him a wide range of powers. Saitama's one-punch style might not be effective against Goku's diverse skills and battle experience.
I don't think there's a clear winner. Both Manga Goku and Manga Saitama have unique and powerful abilities. It could come down to strategy, luck, or even the author's imagination!
I think Saitama is stronger. His power is seemingly limitless and he has never struggled in a fight. Goku, although powerful, has had many intense battles where he was pushed to his limits.
In my opinion, Saitama doesn't have a chance against Goku. Goku has mastered multiple forms of Super Saiyan and has fought incredibly powerful foes across multiple universes. Saitama's strength is impressive, but it's not on the same level as Goku's.
Saitama is a very powerful hero in the One Punch Man universe. He can defeat any opponent with just one punch. He has a simple appearance and a somewhat laid - back personality.
It depends on the size and location of the hole punches. Small holes in non-critical areas might not have a huge impact, but large or in key parts could lower the grade significantly.
The division of martial arts techniques in fantasy novels can be seen in the following examples:
First Punch:X Punch
[Second Punch: Y-Punch]
Third Punch: Z-Punch
Among them, X, Y, and Z represented different fist techniques or names. They could be specific names or code names, or they could be words that represented the characteristics of fist techniques.
In the novel, readers could better understand the X Fist by describing its characteristics such as its strong attack power and low defense power. At the same time, it could describe the characteristics of Y-Fist and Z-Fist and their effects in battle to let readers better understand their usage.
The most important thing in the novel was to make every punch have its own unique characteristics, and these characteristics could bring about substantial changes in the character's combat. This way, the readers would be able to get more involved in the character's battle.
Genos could be an unexpected opponent. He might be forced to fight Saitama due to some mind - control or a misunderstanding in the rules of the tournament. It would be really interesting to see how Saitama would handle fighting his own disciple, and how Genos would fare against his master's incredible strength.
It's very likely that such fanfiction exists. Fanfiction writers often take existing characters and put them in all kinds of situations. Since Bella and Mike are characters from some well - known fictional universes, a writer might have been inspired to write a story where Bella punches Mike. Maybe it's a comical take on their relationship, or a way to add drama to a story.
