Saitama is definitely a popular choice. His overpowered nature provides a lot of interesting angles for fanfiction. For example, you could write about a time when his nonchalant attitude gets him into trouble with the other S - Class heroes who don't understand his strength.
Another plot could be that an S - Class hero loses their powers. They then have to start from scratch and learn what it's like to be a normal person. Along the way, they discover new aspects of themselves and the world around them. This could lead to them developing a different kind of strength, not just physical but also emotional and mental, which in turn could help them regain their powers in a more evolved way.
There's 'Sneaky Swordsman', a Z - class hero in One Punch Man Z - class fanfiction. He doesn't have the most powerful sword skills, but he is very sneaky and can use his environment to his advantage when fighting monsters. And then there's 'Patchwork Puppet', a hero who has a body made up of various parts and can disassemble and reassemble himself to surprise his opponents. These characters stand out because of their unique abilities and the ways they deal with the challenges in the world of One Punch Man.
One idea could be that Saitama enrolls in the school from 'Class'. He'd be this super powerful student that no one really understands at first. His nonchalant attitude towards the school's challenges would be really funny.
Another plot could involve Saitama using his new S - Class status to reform the hero system. He might see all the flaws in it, like how some heroes are more concerned with fame than actually saving people. So, he starts making changes from the inside. He could introduce new training methods or even a new ranking system that focuses more on a hero's selfless deeds rather than just their power level.
One interesting plot could be a Z - class hero's journey to become stronger. Maybe they start off as a weakling in the Z - class but through various trials, like facing off against low - level monsters alone, they gradually gain experience and new abilities. Another idea could be a Z - class hero forming an unlikely alliance with other Z - class heroes to take on a threat that the higher - class heroes overlook. It could be a group of misfits coming together to prove their worth.
Well, One Punch Man fanfiction can be really interesting. Some fanfictions might explore the backstories of the characters in more depth. For example, they could expand on Saitama's life before he became so overpowered. It's fascinating to see different interpretations of the characters' personalities and relationships. Some fanfictions might also introduce new villains or scenarios that the original manga or anime didn't cover, which can add a fresh perspective to the One Punch Man universe.
Yes, there likely is. The Naruto and One Punch Man fandoms are both quite large, and it's common for fans to create crossover fanfictions. These crossovers can be really interesting as they combine the unique elements of both universes, like Naruto's ninja skills with Saitama's one - punch power.
One interesting fanfiction could be where the S class heroes team up in a different way than in the original to face a new super - strong villain. Maybe they have to rely more on strategy rather than just brute strength, which gives a whole new perspective on their characters.
One popular aspect in One Punch Man subterranean fanfiction is the re - imagining of the subterranean races. Writers often give them more complex backstories and motives. For example, some fanfics might depict a subterranean character who has a change of heart and decides to side with the surface - dwellers. This adds an interesting layer of depth to the story as it challenges the traditional view of the subterranean as simply enemies in the original work.
