One common theme is the exploration of her family relationships. Given the complex family dynamic in the original MHA story, fanfics often delve deeper into how her relationship with her father or siblings might develop. Another theme is her growth as a hero. Writers like to show how she overcomes challenges and hones her skills.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). There are numerous MHA fanfics there, and you can specifically search for those related to the female Todoroki character. Another option is FanFiction.net, which also has a wide range of stories. Just use the search bar and type in relevant keywords like 'MHA female Todoroki' to narrow down your results.
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.
Some Tumblr blogs are dedicated to sharing and recommending fanfics. You can search for tags like #Todoroki family fanfic on Tumblr. There might be some users who regularly post their favorite fanfics or even write their own short Todoroki family fanfic pieces on their blogs.
His friends would probably take care of him. Midoriya would be very eager to help, using his kind-hearted nature. He would make sure Todoroki is fed and comfortable.
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.
I think All Might's reaction would be interesting. He might see Loid as a kind of hero in a different sense. Loid's selfless dedication to his mission to prevent war, even if it means living a double life, could remind All Might of his own role as a symbol of peace. All Might would probably respect Loid's determination.
Todoroki's character development in time travel fanfictions can be quite profound. He may start as a somewhat aloof character, but through time travel, he begins to understand the importance of relationships more deeply. When he travels back and witnesses the relationships he could have had or lost, it makes him cherish the ones he has in his original timeline. His view of heroism also evolves. He realizes that being a hero isn't just about using his powers but also about making the right choices at the right time, which is especially highlighted when he has to make decisions that could change entire timelines.
