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.
It expands the universe by exploring the backstories of the characters more deeply. For example, we might learn more about the childhood of characters like King. It also creates new scenarios for the heroes to face, like battles in different dimensions. This gives more depth to the world of One Punch Man.
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.

A fanfiction could show Saitama getting lost in Gotham. Batman finds him and is immediately on guard because of Saitama's strange appearance. But when Saitama just asks for directions in his usual bland way, Batman is a bit taken aback.
One way is to explore his life before he became a hero. Maybe he had a normal job and was constantly frustrated with the mundanity of it. This could have been the catalyst for his intense training.
Overall, 'One Punch Man: The Strongest Man' manga is excellent. It has a unique plot, amazing action scenes, and a good sense of humor. The character development is also impressive.
One way is to delve deeper into his training. Maybe add more details about the hardships he faced during his intense training regimen. For example, he could have had to overcome various natural disasters that occurred while he was training in isolation, like surviving a volcanic eruption near his training area.
They're quite similar. The One Punch manga and One Punch Man have a lot of common elements, like characters and storylines.
In the One Punch Man manga, the train concept is not a central element. The story is more about Saitama's adventures and fighting various monsters and villains.
The punch in One Punch Man manga is often shown as incredibly powerful and decisive, instantly defeating enemies with a single strike.
