One idea could be that all his friends at UA plan a surprise birthday party for him. They decorate the common room with his favorite colors, blue and red. Another plot could be Todoroki spending his birthday with his family, trying to reconcile with his father on this special day. Maybe he receives a heartfelt gift from his mother that has a deep emotional significance.
A possible plot is that Todoroki decides to spend his birthday alone, reflecting on his life and growth. But his classmates find out and one by one they come to him, sharing their memories and how he has influenced them. It could also be a story where Todoroki has a birthday adventure in a dream world, where he has to overcome challenges related to his past and his powers.
For a Todoroki birthday fanfic, you could write about how he spends his birthday helping others in the city. He could be saving people from small disasters, and in return, the citizens of the city throw him an impromptu birthday celebration. Or perhaps he discovers a long - lost family heirloom on his birthday that reveals more about his family's past.
You can make the characters more interesting by exploring their backstories in relation to Todoroki's birthday. Maybe a character had a similar experience on their own birthday that makes them connect with Todoroki on a deeper level. Also, show different sides of the characters. For instance, Uraraka could be the one who comes up with the most creative birthday gift idea, showing her creativity and thoughtfulness towards Todoroki.
One plot idea could be Todoroki exploring his identity through crossdressing in a modern AU. He might start as a bit of an outcast but then find a group of friends who accept him for who he is. Another could be a situation where he crossdresses for a undercover mission at UA and has to deal with the reactions of his classmates. Maybe he also discovers new things about his own self - confidence and how appearance can be a form of self - expression.
Perhaps in a high - school AU for the 'crop top Todoroki fanfic', Todoroki is part of an art project where students have to design and model their own unique outfits. A character creates a crop - top - inspired look for Todoroki, and he has to overcome his initial shyness about wearing it. This could explore his self - confidence and how he deals with being in the spotlight in a new way.
Another interesting concept is a Todoroki family fanfic set in an alternate universe. In this universe, the family could be a normal, happy family from the start. There would be no hero - villain drama, and it could show their day - to - day life, like family dinners, outings, and how they deal with normal family issues.
An OC fanfic could revolve around a healer - type OC who helps Todoroki deal with the emotional scars from his family. The OC uses their calming quirk to soothe Todoroki during his moments of distress, and they form a deep bond.
One plot idea could be a story where the male reader is a new teacher at Fuyumi's school. They initially meet in a professional setting but gradually develop a deeper connection as they discover shared interests. For example, they both might be passionate about helping underprivileged students. Another idea is a scenario where the male reader saves Fuyumi from a dangerous situation, like a villain attack in the My Hero Academia universe. This event could be the starting point of their relationship, with Fuyumi being grateful and slowly falling for the male reader's brave and kind nature.
One idea could be a story where Fem Todoroki has to overcome her self - doubts while training in a new and challenging environment. Maybe she's sent on a special mission with a group of heroes she doesn't know well, and she has to prove herself.
A fanfic could be set during a school festival. Momo is in charge of one of the booths and Todoroki volunteers to help her. They have to deal with various problems like running out of supplies. Momo creates new items with her quirk while Todoroki helps with keeping things cool (literally with his ice) or heating up things when needed. In the process, they share some personal stories and get closer, realizing they have more in common than they thought.
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.
The character's personality traits being highlighted in an endearing way can make a Todoroki fanfic cute. For instance, Todoroki's initial shyness or his confusion about normal, everyday things can be really charming. If the fanfic shows him blushing when complimented or his awkward attempts at small talk, it adds to the cuteness factor.
