SI Becomes One Punch Man Fanfiction: What Could the Plot Be?

Another possibility is that Naruto, in this fanfiction, is given a power similar to Saitama's. He then has to deal with the consequences of having such overpowered abilities. He might struggle with not being able to have a real challenge in battles anymore, just like Saitama. And he could try to find a new purpose in life, perhaps using his new strength to help the people in the One Punch Man universe in a more efficient way than he did in his own world.

To adapt to the One Punch Man world, the SI would have to understand the hero culture. In this world, heroes are not just about fighting but also about popularity and rankings. The SI could try to find their place in this system. They might start by helping out in small ways, like assisting in evacuating civilians during a monster attack. As they gain more experience, they could try to form their own unique identity as a hero. This would involve not only physical adaptation but also mental and social adaptation within the hero community.

In a One Punch Man fanfiction, a great plot could be the origin story of some of the minor heroes. For example, how Mumen Rider got his bike and started his hero journey. Another plot could be a tournament among the heroes to see who is the most skilled (not the strongest since that's Saitama). And a story where Saitama has to deal with a PR disaster for the Hero Association because of his non - traditional hero behavior.

The plot could revolve around a villain who targets Saitama's hair specifically. This villain might believe that Saitama's power is directly related to his hair and tries to steal it or cut it off. Saitama then has to protect his hair while also dealing with the normal chaos of fighting monsters in the city.

A plot could involve Saitama ending up in the Naruto world. He quickly realizes that the power levels here are different. He may get involved in the ninja wars, using his one - punch ability to end battles quickly. Naruto, intrigued by Saitama's power, tries to figure out how he can achieve such strength. Meanwhile, the villains in the Naruto world start to fear this new, extremely powerful intruder.

If Saitama became a monster in fanfiction, his physical appearance would surely change drastically. His bald head, which is now a symbol of his simplicity and power, might take on a more menacing look. His eyes could turn red, and his muscles might bulge in an even more grotesque way. This transformation could also affect his relationships. Genos, for example, would be in a difficult position. He idolizes Saitama as his master, but if Saitama becomes a monster, Genos might have to fight him to protect the city.

One possible plot could be that Saitama somehow ends up in the Marvel universe. He might be mistaken for a new superpowered being by the Avengers. Maybe he just casually punches a big bad like Thanos during one of his attacks, completely oblivious to the whole situation, leaving the Avengers both shocked and amused.

The plot could involve Garou somehow ending up in Saitama's world more permanently. Maybe he decides to team up with Saitama against a common enemy. This new enemy could be a powerful being from another dimension that neither of them could face alone. Their contrasting fighting styles would make for an interesting dynamic, with Saitama's one - punch power and Garou's martial arts skills.

One possible plot could be that a new and extremely powerful villain emerges who is not impressed by Saitama's one - punch ability at first. This villain manipulates the rules of the tournament to his advantage, creating unfair match - ups for the heroes. The heroes then have to find a way to overcome these obstacles while also dealing with their own rivalries and personal growth. For example, Genos could be paired against a much stronger opponent early on, and in the process of trying to defeat this foe, he discovers a new power - up within himself.

Perhaps Si could be a new hero who has the power to absorb the powers of defeated monsters. This would make him a very controversial figure among the hero community. Some would see him as a threat, while others would recognize his potential to become one of the strongest heroes. He could also have a complex backstory related to a secret experiment that gave him this power.
