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.
To make your Kid OC x My Hero Academia fanfiction stand out, explore unique relationships. Maybe your OC has a crush on Todoroki and tries to get his attention in a cute but clumsy way. Or they could have a rivalry with Mineta because they think his behavior is inappropriate. Additionally, don't forget to describe the world of My Hero Academia vividly. Mention the different hero agencies, the technology used, and the social hierarchy among heroes and villains.
There's also 'Growth Together'. This fanfic shows how Deku and Todoroki support each other during tough times at UA. They face challenges not only from villains but also from within the school. Their relationship develops as they help each other overcome these obstacles.
A great first meeting scene could be during a hero training exercise. The OC is new to the class and Katsuki sees her as an easy target to show off his skills. He charges at her during a mock battle, but the OC surprises him with her quick thinking and unique quirk, leaving him both frustrated and a bit intrigued.
Your fanfiction could start with the OC accidentally stumbling upon Todoroki in a moment of vulnerability. Maybe he's having a flashback about his father. The OC offers comfort, and this starts their relationship. Then, they could be chosen to represent their class in a hero tournament. Working side by side, they face tough opponents and their bond grows stronger. You could also add a sub - plot where other students are jealous of their newfound closeness, creating some interesting drama.
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.
Todoroki was on a mission to rescue some hostages. As he entered the building, he didn't notice the hidden traps. One of the traps, a powerful blast of energy, hit him directly. He was thrown back, hitting his head on a wall. His vision blurred and he could feel a sharp pain in his ribs. He struggled to get up, but his body was in shock. The villains took advantage of his weakened state and closed in on him. He thought about his training and tried to gather his strength to fight back.
Well, a good start would be to establish their relationship at the beginning. Are they friends, rivals, or something more? If they're friends, you could show them training together. Let's say your OC has a power related to speed and Momo uses her creation quirk to make things that help in training, like agility courses. As for the plot, it could involve a school competition where they have to work as a team against other students. You can also add some drama by having someone from the school misunderstand their relationship and cause some trouble. This will add layers to the story and keep readers interested.
First, you need to understand the characters well. Nejire is known for her bubbly and energetic personality. For the OC, develop a unique backstory and set of powers. Then, think of a situation that brings them together, like a joint mission. Maybe the OC has a special ability that Nejire is intrigued by, and they start to form a bond as they face challenges during the mission.
Another concept is that Todoroki was turned into a vampire by a villain's quirk gone wrong. He then has to find a way to reverse it. He teams up with Midoriya, who is determined to help his friend. They search for a mysterious old hero who might know a cure, all while Todoroki battles his inner vampire nature.
To write a fanfiction about a My Hero Academia OC in a class, start with a strong concept for your OC. Let's say your OC has a quirk called 'Sound Mimicry' where they can imitate any sound they've heard. They enter the class and immediately face the challenge of standing out among so many unique quirks. You can write about their first day in class, how they introduce themselves, and how the other students react. As the story progresses, you can create story arcs for them. Maybe they get involved in a tournament and have to use their quirk in creative ways to win. Along the way, develop their relationships with the teachers and classmates, like forming a friendship with Ochaco or getting mentored by Aizawa.
