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.
Another way is by exploring their insecurities. Tatsumaki might be insecure about her powers not being enough in some situations, and Saitama, although he seems invincible, might have his own internal struggles. When they open up to each other about these insecurities, it creates a more profound connection. Writers can then build on this connection, showing how they support each other and how their relationship evolves as a result.
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.
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.
Writers develop their characters by exploring their backstories more deeply. For Genos, they might expand on his past traumas that led him to become a cyborg and his determination to avenge his family. For Saitama, they could dig into his days before becoming so powerful. Another way is through dialogue. The conversations between Genos and Saitama can show their growth and how they influence each other. For example, Genos might start to question his own motives after talking to Saitama about the true meaning of being a hero.
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.
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.
When writing their character dynamics, consider their powers. Saitama's physical strength is limitless, while Tatsumaki's psychic powers are vast. This can lead to interesting situations. For instance, Tatsumaki might try to use her powers to move Saitama as a joke, but it doesn't work. This creates a humorous moment and also shows their relationship. Also, show how Saitama's lack of fear affects Tatsumaki. She might be used to people being intimidated by her, but Saitama is different. This can lead to her respecting him more and changing her attitude towards him. Their character dynamics should be a mix of comedy, action, and a bit of romance if the fanfic is going in that direction.
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.
In a fanfiction, Mosquito Girl could develop a grudging respect for Saitama. After being defeated by him, she realizes that there are beings far more powerful than her. And Saitama, on the other hand, might start to see Mosquito Girl as more than just a villain. Maybe he discovers that she has some good qualities, like her tenacity. So their relationship could shift from pure enmity to a more complex dynamic of mutual understanding.
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.
Well, it could develop in a really comical way. Imagine Tatsumaki trying to teach Saitama some 'proper' hero etiquette, but Saitama just doesn't get it. However, through these interactions, they start to understand each other better. Tatsumaki sees Saitama's kindness and Saitama sees Tatsumaki's determination. This mutual understanding could lead to a unique relationship in the fanfiction.
