One common theme is the power dynamic. Since Todoroki has powerful abilities in the My Hero Academia world, the OC often has either complementary powers or is in awe of his powers. Another theme is the breaking down of Todoroki's emotional barriers. He can be a bit reserved, and in these fanfics, the OC usually helps him open up. Also, friendship - to - love is a typical theme. They start as friends or classmates and gradually develop romantic feelings for each other.
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.
One popular Todoroki x OC fanfic is 'A New Flame'. It has a well - developed OC who enters the world of the My Hero Academia universe and has an interesting relationship with Todoroki. The story focuses on how their bond grows over time, with the OC having unique powers that complement Todoroki's. Another great one is 'Todoroki's Unlikely Companion'. This fanfic delves into how an OC with a troubled past manages to break through Todoroki's somewhat cold exterior and form a deep connection with him. It's really engaging as it shows the character development of both the OC and Todoroki.
Once upon a time, there was a Todoroki sister OC named Hana. She had the same white and red hair as her brother Shoto. Hana was often in the shadow of her powerful siblings. But she had a unique power of her own - the ability to manipulate ice and fire separately, not just together like Shoto. One day, she decided to prove herself. She entered a hero competition at school. At first, everyone underestimated her. But as the challenges went on, she showed her true strength, impressing everyone with her precise control over her powers.
One idea could be that the OC is a new student at UA High School. She has a unique quirk that Shouto finds fascinating. They get paired up for a training exercise and gradually start to understand each other better. As they face challenges together, a bond forms between them.
Love and friendship are also common themes. The fanfics often show how the OC and Todoroki grow closer, whether it's through shared experiences at UA or facing external threats together. Their relationship can start as friends and slowly develop into something more romantic over time.
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.
You could write their first meeting in a really intense situation. Like during a villain attack at the school. The OC could be trying to save some students and Todoroki comes in to help. Their eyes meet, and there's an instant connection. Or perhaps it's a more ordinary setting like in the cafeteria. The OC accidentally spills their drink on Todoroki and they start off on a bit of a rocky note, but then Todoroki is intrigued by the OC's apology and sincerity.
There's 'A New Hope for UA' which is also a very good MHA OC fanfiction. In this, the OC has a quirk that is initially seen as weak but they manage to use it in innovative ways. The fanfiction does a great job of integrating the OC into the existing MHA universe, with lots of references to the original series.
One aspect of Todoroki x Midoriya fanfic could be the exploration of their contrasting personalities. Todoroki is often stoic and reserved, while Midoriya is more enthusiastic and emotional. In fanfics, this contrast can lead to interesting character dynamics, such as Todoroki being gradually thawed by Midoriya's warmth and Midoriya learning from Todoroki's calmness. It can also delve into their shared experiences at UA High, like how they support each other during battles or training sessions, which deepens their bond in the fan - created stories.
