Another idea for a fanfic could be that Todoroki's brother is a support character who helps Todoroki overcome his internal struggles. He might be the one with great emotional intelligence, able to understand Todoroki better than anyone else. Through their interactions, Todoroki could grow and develop as a character, and the fanfic could focus on their bond, which is often overlooked in the original story.
One common theme is self - discovery. Since the Todoroki character has a complex family background, in fanfics with a female Todoroki, she often has to discover who she really is outside of her family's expectations. For example, she might find new ways to use her quirk that her father never considered.
Maybe the fanfic could focus on the brother's backstory. He might have been bullied as a child because of his family name or his lack of a 'powerful' quirk at first. This could lead to him developing a strong sense of justice and a desire to protect those who are weak. His journey from a bullied kid to a confident hero - in - training would make for an interesting story.
One common theme is Todoroki's reaction to new and different fast foods. Since he has a rather reserved personality in the original series, seeing him react to something as ordinary as fast food can be really interesting. Another theme could be his interactions with other characters in a fast - food setting. For example, his friends might be dragging him to try new things.
One popular 'bnha female todoroki fanfic' is 'A New Path for Todoroki'. It explores a different side of a female Todoroki in the BNHA universe, showing her struggles and growth in a unique way.
One popular BNHA Todoroki fast food fanfic could be 'Todoroki's Fast Food Adventures'. It might show Todoroki trying different fast foods in a really fun and comical way. Another could be 'Fast Food and Todoroki's Quirk', which might explore how his quirk could interact with fast food in some unique situations.
The Bnha universe's reaction would be mixed. Those who are into complex stories, like Todoroki, might study the relationships in Hamilton fanfiction. But others, like Mineta, might not be interested at all because it doesn't have much to do with his usual interests. Overall, it would depend on the individual characters' personalities and interests.
Midoriya's friends like Uraraka and Iida would be extremely worried. They would immediately start looking for him. Uraraka might use her quirk to search in the air, while Iida would lead the ground search with his speed. Bakugo, on the other hand, would be furious. He would probably go on a solo mission to find Deku and take on Todoroki without hesitation.
Some would be inspired. Characters like All Might might see Peter Parker's journey as similar to his own in some ways. Both are trying to do good in a world full of challenges. All Might could appreciate Peter's determination to protect his city despite having a normal life outside of being a hero.
For heroic - centric fanfictions, they would likely be disdainful. Since they oppose heroes, seeing stories that glorify heroes would annoy them. They might scoff at the idealized versions of heroes in those fanfictions.
