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.
A frequent theme is the use of Todoroki's quirk in relation to fast food. Maybe his ice or fire power could be used to cool down or heat up his food in a unique way. Also, the exploration of Todoroki's character development through his experiences with fast food is common. He might start to loosen up and become more social as he gets involved in the fast - food culture in the fanfic. Additionally, there could be themes about the fast - food industry in the BNHA world, like how it operates and what kind of strange fast foods they might have.
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.
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.
Another theme is self - discovery. Working in a fast - food place or just being in that setting makes them learn more about themselves. For example, Todoroki might discover he has a liking for a certain type of fast food that he never knew before, which is also a symbol of his personal growth.
One common theme is family. Given Todoroki's complex family situation in the original story, many fanfics explore his relationship with his father, mother, and siblings further. Another theme is friendship. They often show how Todoroki forms deeper bonds with his classmates.
One common theme is friendship development. Given their different personalities, seeing how they grow to become friends or at least respect each other more is a popular plot. For example, they might start off as rivals in a hero training exercise and end up having each other's backs.
A common theme is the struggle to balance his hero duties and his family life. In many pregnant Todoroki fanfics, he has to figure out how to be there for his partner during the pregnancy while still being a hero. There's also the theme of hope for the future, as the coming of a new baby represents a new beginning full of possibilities for Todoroki and those around him.
One common theme is isolation. In many of these fanfics, Todoroki feels alone despite being surrounded by people. He has trouble opening up about his past and his emotions, which leads to a sense of being cut off from others.
One common theme is rivalry. Bakugo's aggressive and competitive nature against Todoroki's more reserved yet powerful self makes for an interesting dynamic. Another theme is friendship development, as they often start off at odds but then find common ground.
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 the characters' costumes. It's fun to see how the writers imagine the heroes and villains in different Halloween - themed outfits.
