A fanfiction idea could be that Saitama's hair growth is the result of some strange experiment. With his new handsome look, he accidentally becomes a model for a new line of superhero - inspired fashion. However, he still goes on his usual hero - hunting adventures, and his friends are both amused and a bit jealous of all the attention he's getting.
Well, perhaps Saitama's hair gives him some new powers. Since he's now handsome with hair, his confidence soars, and this unlocks a hidden potential within him. He could use these new powers to defeat stronger villains more easily.
Saitama is a very powerful hero in the One Punch Man universe. He can defeat any opponent with just one punch. He has a simple appearance and a somewhat laid - back personality.
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.
Sometimes King is paired with Saitama. King, known for his false reputation of being a super - strong gamer in the original story, could be in interesting interactions with Saitama in the fanfiction's gaming context. Maybe they compete in a gaming tournament within the fanfiction, and Saitama's effortless wins baffle King.
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.
Genos could be an unexpected opponent. He might be forced to fight Saitama due to some mind - control or a misunderstanding in the rules of the tournament. It would be really interesting to see how Saitama would handle fighting his own disciple, and how Genos would fare against his master's incredible strength.

Initially, Saitama Shirazawa only wanted to study hard. It was only when she found a sealed blood-colored notebook in the law firm that she broke her peaceful life.
Sister Sadako, why are you in my book?
Human-faced Hound, why are you chasing me!
Tomie-san, let me explain!
Demons and monsters, supernatural beings, but why are you always chasing after me!
With no other choice, Saitama Shirazawa could only pick up her notebook and begin her crazy exorcism.
"Everyone, don't be anxious. I'll ferret you all over."
"Wait, I'm here to release them. Why are they all in my book?"
"Master, please use this servant's Spirit-Cleansing Technique to your heart's content!"
Shirasawa Saitama: "Tokyo City Legends Training Record???"
"This is different from what I thought!"
I hope you will like this book.
He could interact with Tsukune, the main human character in the Yokai Academy setting. They might share their experiences of being different in their respective worlds.
Well, Saitama All Fiction could potentially refer to a fan - created idea that emphasizes Saitama's ability to be above all the normal rules of the fictional One Punch Man universe. For example, his strength is so overwhelming that it's like he exists in a realm of his own, where the typical limitations of the story don't really apply to him. He can defeat any foe with just one punch, and this 'All Fiction' concept might be an attempt to explain how and why he's so powerful in such a ridiculous way.
