The fanfiction about Fubuki and Tatsumaki in One Punch Man is alluring because it gives a chance to expand on their characters. Fubuki, with her ambition to be a great hero, can be explored further. Maybe in a fanfic, she overcomes her insecurities related to her sister Tatsumaki's much stronger powers.
Many One Punch Man fanfics with Fubuki and Tatsumaki focus on their interactions with other characters too. They could be paired with Saitama in some comical or action - packed situations. Like, Fubuki trying to recruit Saitama into her group while Tatsumaki is constantly skeptical of his abilities.
One Punch Man is a really popular anime. Fubuki, as a character in it, has a lot of potential for fanfics. In a fanfic about them, it could explore their relationship in new ways. Maybe it could show Fubuki trying to recruit Saitama into her group in a more detailed and different way than in the original story. It could also develop her character further by showing her reactions to Saitama's overpowering strength in unique scenarios.
She is often portrayed as extremely powerful. Her psychic powers are usually magnified in fanfiction, allowing her to perform even more incredible feats. For instance, she might be able to move entire cities with her mind.
One possible plot could be that Fubuki, being frustrated with her lack of progress in terms of power compared to Saitama, decides to train with him. This would lead to a series of comical and at the same time, character - building moments. Saitama would probably give her some really simple but effective training advice that she initially scoffs at but later realizes is genius.
Tatsumaki in fanfiction can be portrayed in different ways. One aspect could be her origin story exploration. Writers may delve deeper into her past, perhaps how she came to be so powerful. This could involve her training, or any events that shaped her personality. Also, her interactions with villains in fanfiction can be interesting. She might face new and more challenging foes that test her limits in ways the original manga may not have.
One popular theme is Tatsumaki's relationships. It could be her relationship with other heroes like Saitama or Genos. Another common theme is her growth as a character, both in terms of her powers and her personality. Some fanfictions also explore her backstory in more depth.
One popular plotline is Tatsumaki trying to get Saitama to take things more seriously in battle. Since Saitama is so overpowered, Tatsumaki, with her strong sense of pride in her own abilities, might feel frustrated by Saitama's nonchalant attitude. Another plotline could be a team - up against a powerful new villain. The contrast between Saitama's simple yet extreme strength and Tatsumaki's more complex psychic powers would make for an interesting dynamic in combat.
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.
