The concept could be expanded by giving the punch different properties. For instance, it could have the ability to nullify an enemy's special powers instead of just knocking them out physically.
In some fanfictions, the strongest punch could have a different impact on Saitama himself. Instead of being a simple display of his overpowered strength, it could start to drain his energy in a new way. This would add an interesting twist to his character, as he would have to be more cautious about when and how he uses his ultimate move.
Saitama is the main character. He is a bald - headed hero who can defeat any opponent with a single punch. He's a bit of an underdog in the sense that his power is so great that he's bored with fighting most of the time.
Genos is also a main character. He is a cyborg who becomes Saitama's disciple. He is very powerful but not nearly as strong as Saitama. He is constantly seeking ways to improve his strength and learn from Saitama.
It's a tough call. Goku has the ability to keep getting stronger through training and achieving new forms like Ultra Instinct. However, Saitama has shown that he can defeat any opponent with one punch so far. But Goku's powers are more defined in terms of levels and growth potential. So, it's hard to say who would be the strongest in a crossover. It could depend on the situation and how the writer wants to portray their encounter.
Saitama is the most important character in the One Punch Man background story. He's the One Punch Man himself, with his extreme power. Genos is also important. He's a cyborg who becomes Saitama's disciple. He admires Saitama's strength and wants to learn from him. King is another notable character. He has a reputation as a very strong hero, but in reality, he just has a lot of luck and often takes credit for Saitama's work.
Definitely Saitama. He's the main character and his nonchalant attitude towards his incredible power is always interesting to explore in fanfiction. Also, Genos. His loyalty to Saitama and his own journey to become stronger make him a great addition.
Saitama is definitely the most memorable. His nonchalant attitude towards fighting and his extreme strength make him stand out. He doesn't care about fame or glory, he just wants to be a hero for fun.
Sure. Saitama is bound to be an interesting character in it. His nonchalant attitude towards his extreme power is always fun to explore. Genos, his disciple, with his intense loyalty and robotic nature, would also add depth to the story.
