One interesting story could be about an OC with a unique power that they struggle to control at first. For example, an OC who can manipulate time in small increments but accidentally freezes themselves often. Another might be an OC who is a hero trying to prove themselves in a world dominated by Saitama's overpowering strength.
You can start by looking on popular fanfiction websites such as Archive of Our Own (AO3) or FanFiction.net. Just type in 'One Punch Man OC' in the search bar and browse through the results. Check the ratings and reviews of the stories to get an idea of their quality.
You could create an OC who is a gamer in the One Punch Man universe by giving them a special power related to video games. For example, they might be able to use 'power - ups' from games in real - life battles, like a speed boost or invincibility for a short time. Their backstory could be that they were a normal gamer who got sucked into the One Punch Man world and had to adapt their gaming skills to survive.
Another concept might be an OC that has a strange origin story. Maybe they come from a far - off planet where the laws of physics are different, and they have to adapt to Earth's environment while also dealing with the various threats in the One Punch Man world. This could lead to some really cool character development and interactions with other characters.
To improve 'bad oc one punch man fanfiction', one needs to focus on the plot. A good plot should have a clear beginning, middle, and end. It should build tension and resolve it in a satisfying way. Also, the oc should be integrated into the story in a natural way. They should have interactions with the existing characters that make sense. Moreover, getting feedback from other One Punch Man fans can help identify the weak points and areas for improvement.
One common problem could be out - of - character portrayals. For example, the original One Punch Man characters might act in ways that completely go against their established personalities in the official story. Another issue might be a lack of a coherent plot. It could jump from one random event to another without proper build - up or connection. Also, bad grammar and spelling mistakes can make it difficult to read and understand the fanfiction.
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.
Start with a relatable situation for the gamer OC, like being new to the One Punch Man world and having to figure out the rules. Then, introduce a conflict such as a powerful villain that the OC's gaming skills are uniquely suited to defeat. Throw in some twists, like the villain also having some knowledge of gaming mechanics and using it against the OC.
One of the main challenges is the power scaling. DC Comics has a complex power hierarchy, and One Punch Man characters are often absurdly powerful. Integrating an OC with that level of power without breaking the existing power balance is tough. Another issue is the tonal difference. One Punch Man has a very distinct comical and somewhat satirical tone, while DC Comics has a range of tones from dark and gritty to more light - hearted. Making the OC fit into the various DC storylines while maintaining their One Punch Man - like essence is difficult. Also, there's the matter of character design. Ensuring that the OC doesn't look out of place among the iconic DC character designs is a challenge.
