One Punch Man Monster Saitama Fanfiction: What are some interesting plot ideas for it?

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.

One idea could be that Evil Saitama is actually a clone created by a mad scientist. The clone has all of Saitama's power but none of his morality. He starts to create chaos in the hero world, challenging heroes and causing destruction. Another plot could be that Evil Saitama is an alternate version from a parallel universe where he turned bad due to a tragic event in his past. He then travels to the main One Punch Man universe to seek revenge on the heroes there.

One idea could be Saitama and Tatsumaki teaming up to face a new, extremely powerful villain that even Saitama has trouble with at first. Maybe this villain has the ability to manipulate reality in a way that nullifies Saitama's strength for a short time, and Tatsumaki has to use her psychic powers to protect Saitama while he figures out a way to overcome this new obstacle.

One idea could be Saitama facing an enemy that can copy his strength but not his speed. This would create a unique dynamic as Saitama has to use his wits more than just his punch. Another plot could involve Saitama traveling to a different dimension where his power is nullified and he has to start from scratch to regain his strength. And perhaps a plot where Saitama has to train a new hero who is having trouble controlling their own power, similar to how he was once a regular person trying to become strong.

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.

Maybe Saitama accidentally breaks a world record in strength while doing something mundane like opening a jar. Scientists and the media get involved to investigate this strange occurrence. They test his strength in various ways and are completely astounded by his limitless power. This discovery makes Saitama a global sensation and he finally gets the recognition he has long been overlooked for.

One interesting fanfiction storyline could be that Genos discovers a prophecy that Saitama is going to lose his powers. Genos then goes on a mad quest to find a way to prevent this from happening. He visits all kinds of strange places and consults with various powerful beings. Another could be that there is a competition among heroes to see who can train the best new recruit, and Saitama and Genos enter together. They face off against other hero - trainer pairs in various challenges. Also, a story where Genos creates a virtual reality world for Saitama to experience different kinds of battles that he normally wouldn't encounter in the real world, just for Saitama's amusement.

One possible plot could be that in this fanfiction, an alternate dimension where Saitama is a cannibal. Maybe there's a virus that has infected him and turned his moral compass upside down. Writers might explore how the other heroes react to this new, terrifying Saitama. Do they try to cure him? Or do they see him as a threat and try to stop him by force?

One possible storyline could be Boros surviving his encounter with Saitama and then seeking redemption. He realizes the vastness of Saitama's power and decides to train under him. This would be an interesting twist as Boros was initially a villain. Another could be a what - if scenario where Saitama and Boros team up to face an even greater threat that arrives on Earth. It would show their dynamic as they work together, with Saitama's nonchalant attitude and Boros' more serious and battle - hungry nature.

The plot could involve Saitama teaching a group of new heroes how to face their fears. He would tell them about his own journey, starting as an ordinary guy who decided to become a hero just for fun. Saitama could teach them that no matter how strong the enemy is, one should not be afraid to take the first step. He might use his one - punch knockout strategy as a metaphor for facing difficulties head - on, even if it seems impossible at first.
