One interesting storyline could be that your OC is from another dimension and has come to the One Punch Man world. They bring with them a different set of powers and values. This could lead to all sorts of clashes and also new alliances. Maybe they initially think the heroes in this world are too laid - back or too violent, and they try to change the way things are done. Or perhaps their power is something that is desperately needed in this world to fight a new and powerful enemy that the regular heroes can't handle on their own.
One idea could be a male OC who has the power of telekinesis. He could be a former scientist who was exposed to some strange radiation during an experiment. This power would set him apart from the existing characters in One Punch Man. He might initially struggle with controlling his power, leading to some comical or dangerous situations.
First, focus on the character's origin. Explain how your male OC got his powers or what led him to become the person he is. For example, if he has super strength, was it a genetic mutation or the result of some training? Then, create a conflict. Maybe he wants to join the Hero Association but faces discrimination because of his unorthodox methods. This conflict will drive the story forward.
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.
A possible plot is that the OC is a former enemy of Fubuki who has seen the error of their ways. They try to make amends by helping Fubuki in her quest to become stronger and more respected in the hero community. This could involve training sessions where the OC shares some unorthodox fighting techniques that complement Fubuki's psychic powers. The OC could also have connections to some powerful and mysterious figures in the One Punch Man universe, which could open up new storylines for Fubuki.
The OC can be introduced as a new recruit in Fubuki's group. For example, they could be a young and inexperienced hero who is in awe of Fubuki's powers and leadership. They start by following Fubuki's orders and gradually prove themselves useful in battles.
First, think about their power. In One Punch Man, powers can be really wacky. So for your OC, it could be something like the ability to turn into any type of food, which would be both funny and unique. Then, consider their backstory. Maybe they were an ordinary chef who got their powers from a strange experiment in the kitchen. Also, don't forget about their personality. They could be really laid - back and love to share their food - power with others. This way, your OC will fit well into the One Punch Man DoS fanfiction world.
It could work well if the OC's powers and personality are balanced and integrated seamlessly. The DC universe is vast, so there's room for unique characters.
Another fanfiction concept could be that the monsters in the 'Danmachi' dungeon start to mutate in a way similar to how the monsters in 'One Punch Man' are strange and powerful. This would force the adventurers in 'Danmachi' to come up with new strategies, and perhaps some of the heroes from 'One Punch Man' could come to help out, like Genos, who could provide some technological insights on dealing with these new threats.
Similarities? Well, both are super - powerful. They both are often the ones to save the day in their respective universes. Differences? One Punch Man's power is very straightforward - that one punch. Superman has a whole range of powers. In fanfiction, One Punch Man might be more of a comical character in his overpoweredness, while Superman is more of a traditional hero figure.
