One possible plot could be that Tornado initially challenges Saitama out of pride. She sees his nonchalant attitude and wants to prove that her psychic powers are superior. Saitama, being Saitama, just goes along with it. As the battle unfolds, Tornado throws everything she has at Saitama, but he just dodges casually. Eventually, Saitama throws a light punch that knocks Tornado back, but not seriously hurt, which makes her realize his true strength.
In a fanfiction scenario between Tornado and Saitama, Saitama would likely win. He's so overpowered that he can defeat any opponent with one punch. Tornado is extremely strong with her psychic powers, but Saitama's strength seems limitless. His simple training routine has made him so powerful that no enemy has been able to withstand his punch so far.
One Punch Superman Saitama VS Tornado was the 191st chapter.
Chapter 191," Tornado's Counterattack ", tells the story of the battle between Saitama and Tornado. The two met on the street and Saitama was provoked by Tornado and was involved in the battle. In the battle, Tornado displayed her powerful strength. She used a type of Qigong wave called "Tornado" to attack her opponent, forcing Saitama to display even more strength to fight against her. In the end, Saitama defeated Tornado through his relentless efforts, demonstrating his unparalleled strength and tenacious will.
Identity exploration is also a theme. The sister might be struggling with being in Saitama's shadow or trying to find her own identity as a hero or just as an individual. She could be trying to make a name for herself without relying on her brother's fame.
One good fanfiction could be 'Saitama's Sister: The Hidden Power'. It explores the idea of Saitama having a sister with her own set of powers. In this story, she tries to keep up with her brother's reputation while also finding her own place in the hero world.
Saitama's true strength was recognized by many in One Punch Superman. With the help of his neighbor and teacher, Dr. Orochi, people gradually understood his strength. Dr. Orochi had once told Saitama that he had powers beyond that of a human, and that he could strengthen himself through training. In addition, Saitama's teacher, Hungry Wolf, also called him the " strongest human." In addition, other characters such as Superman and Atom also acknowledged Saitama's strength.
Saitama might be really frustrated with Mosquito Girl. Since he can defeat most powerful foes with one punch, but a mosquito girl would be a different kind of annoyance. She could be constantly buzzing around and trying to bite him, and Saitama would probably just try to swat her away like a normal mosquito at first. But when he realizes she's a 'villain' in her own right, he might just give her one quick punch to end the nuisance.
In a battle between One Punch Man and Superman, it's really tough to say. One Punch Man can defeat any opponent with just one punch. But Superman has incredible strength, speed, and a whole bunch of other powers like heat vision and flight. If One Punch Man managed to land his one punch, he could win. However, Superman's speed might make it difficult for One Punch Man to even get a hit in. So, it could go either way depending on the circumstances.
To write a character - driven story about Saitama, focus on his boredom. Show how his extreme power has made his life lackluster. For example, you could write about his attempts to find a hobby that actually challenges him. Maybe he tries painting, but he's so good at it immediately that he gets bored. This exploration of his search for something to fill the void in his life can be a great character - driven story.
