One Punch Man Evil Saitama Fanfiction: What are some interesting plot ideas?

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.

A cool plot might be a time - travel fanfiction. Saitama travels back in time to when he was just starting to become strong. He meets his past self and tries to guide him, but also has to deal with monsters from that era who are now different threats due to the time shift. And there could be a mystery element where Saitama has to figure out why time is acting strangely in the first place.

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.

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.

Well, one possible plot twist could be that Saitama's boredom turns into a malicious form. Since he's so powerful and always bored from easily defeating enemies, this new evil side might start creating stronger foes just to have a real challenge, but without caring about the destruction it causes. He could also turn against the other heroes, seeing them as weaklings not worthy of his time anymore.

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.

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.
