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.
There could be a story where they both participate in a hero - training exercise together. At first, Tatsumaki tries to show off her powers and outdo Saitama. But Saitama doesn't really care about competing. As the exercise goes on, they face unexpected challenges that require them to rely on each other's unique abilities. This could be a great opportunity for their relationship to grow, whether it's a friendly bond or a romantic one.
One idea could be Saitama and Tatsumaki teaming up to face a new, extremely powerful villain that even Saitama has trouble with at first. Maybe this villain has the ability to manipulate reality in a way that nullifies Saitama's strength for a short time, and Tatsumaki has to use her psychic powers to protect Saitama while he figures out a way to overcome this new obstacle.
In some fanfictions, Saitama's growth is shown in his relationship with Tatsumaki. He might start to care more about her well - being, which is a new emotion for him. This could be a sign of his growth as a character who was previously quite detached from others on an emotional level. Tatsumaki's character growth could be about her learning humility. When she sees Saitama's true strength and his simple yet effective way of being a hero, she could become less prideful and more focused on the essence of heroism rather than just her own power and status.
In a romantic setting, their relationship might start off slowly. Saitama would probably be oblivious to Tatsumaki's initial feelings. Tatsumaki, being the proud and strong - willed character she is, would have a hard time expressing her emotions directly. It could start with small acts of kindness from Tatsumaki towards Saitama, like using her powers to fix his apartment when it gets destroyed in a fight. Saitama might just think it's a normal thing at first.
One possible plot idea could be that Tatsumaki gets injured during a battle and Saitama has to take care of her. This would force them to interact closely and start to understand each other better. Another idea is that they are both chosen for a special mission together. Along the way, they face various challenges that require their combined powers. Tatsumaki might initially be dismissive of Saitama, but as they work together, she realizes his true strength and value. This could lead to the development of a deeper relationship between them.
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.
Some writers develop their relationship through shared experiences. Let's say they both get transported to a strange dimension. In this new and dangerous place, they have to depend on each other. Saitama might use his strength to protect Tatsumaki from physical threats, while Tatsumaki uses her psychic powers to navigate and solve puzzles. Through these shared experiences, a bond forms. They start to respect each other's abilities and personalities more, which could lead to a deeper connection, be it friendship or love.
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.
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.
