A fanfiction where someone is reborn as Saitama would likely involve some comical elements. Since Saitama is often bored because he defeats enemies with one punch, the reborn character might come up with creative ways to make his hero life more interesting. They could also interact with other popular characters in One Punch Man in unique ways. For instance, they might have a different approach to dealing with Genos, perhaps teaching him some new skills rather than just having him as a disciple.
It could be really exciting. The character might use their prior knowledge to deal with threats in a different way. Maybe they would try to train others to be stronger faster, instead of just punching everything alone.
The story could start in the middle of a fight. The character, now reborn as Saitama, is in the middle of a battle against a monster. They instinctively use Saitama's one - punch power to defeat the monster and then are left standing there, realizing what has just happened. They then start to think about how they got there and what they should do next in this new life as the world's strongest hero.
In a fanfiction scenario between Tornado and Saitama, Saitama would likely win. He's so overpowered that he can defeat any opponent with one punch. Tornado is extremely strong with her psychic powers, but Saitama's strength seems limitless. His simple training routine has made him so powerful that no enemy has been able to withstand his punch so far.
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.
Tornado of Terror would likely be one of the first to try and take on Evil Saitama. She's powerful and confident, but she would soon realize the extent of his power. Mumen Rider, despite being weak, would still stand up to Evil Saitama out of a sense of justice. He would be quickly defeated but his act of courage might inspire other heroes to step up.
A plot where Saitama travels to different dimensions in the One Punch Man universe. He could encounter strange versions of himself or other heroes and villains, leading to humorous and action - packed situations.
Saitama would be shocked at first. He's used to Genos being around, always eager to learn from him. He might stand there in disbelief for a while.
If Saitama joined the Avengers, it would be a game - changer. His incredible strength could easily defeat most of the villains they face. For example, Thanos might not even be a challenge for him. Saitama's simple - minded but determined personality would also bring a new dynamic to the team. He might not fully understand all the complex superhero politics, but he would just focus on getting the job done, which could inspire the other Avengers to be more straightforward in their approach.
Well, a lot of One Punch Man fanfictions about heroes seeing Saitama are really interesting. Some focus on their initial shock at his power. For example, Genos is always in awe of Saitama's strength in the original work, and in fanfictions, this can be explored even deeper, like how he tries to understand the source of that power.
One common theme is the exploration of Saitama's power in different universes. For example, when he crosses over to a universe with magic, how his physical strength compares to magical abilities.
The novelty. Since Saitama is originally male, a female version brings a fresh perspective. It allows for new storylines and character interactions. For example, how would a female Saitama interact with the male - dominated hero society in One Punch Man? It also gives room for exploring different power dynamics and emotional responses.
