Maybe it's a group of friends who are all interested in different academic fields such as science, art, and literature. They support each other through their academic journeys, help each other with their projects, and together they explore the vastness of knowledge in the academia.
A brilliant but underdog student who has a passion for learning and finally gets the recognition he or she deserves.
Perhaps it's about a group of students from different backgrounds coming together to form an innovative study group. They share their unique knowledge and skills, and together they aim to change the traditional academic approach in their school or university. They might introduce new teaching methods, start interdisciplinary projects, and face resistance from the old - fashioned faculty but eventually succeed in making a positive impact.
An ex - military bodyguard with a tough exterior but a soft heart. He could be protecting a famous athlete who is facing threats from gamblers who want him to lose on purpose. The athlete is very competitive and at first clashes with the bodyguard, but later they become friends and more.
It could be Deku's son or daughter. They would inherit some of his amazing quirk, but also face the pressure of living up to their father's legacy. They would have to carve their own path in the hero world.
The main characters could include Eri. She has a very interesting quirk and her own story of recovery. At the daycare, she could be like a big sister to the other kids. Todoroki could also be a main character. His dual - quirk nature would be fascinating for the kids to learn about. And of course, Aizawa could be a daycare supervisor. His no - nonsense attitude would keep the daycare in order, and his erasure quirk could be used in case any of the kids' quirks get out of hand.
One option is a cat named Whiskers. Whiskers has the unique quirk of being able to create illusions. It teams up with a cat named Paws, who has a super - speed quirk. Another main character could be a cat named Mittens. Mittens has a quirk that gives it the power to control water. These three cats could be the central figures in the My Hero Academia cats fanfiction. They might start out as regular cats but then discover their quirks and decide to use them for good in a world full of both cat and human heroes and villains.
The main character could also be a gender - bent Ochaco Uraraka. Imagine her with her cute and charming personality but in a female - dominated hero world, being courted by different male characters. Her gravity - controlling quirk would also make her a powerful and interesting character in this setup.
The main characters could also be students who are not related to the current heroes but are inspired by them. They could come from different backgrounds, like a student from a family of villains who wants to break free and become a hero. Or a character who has a very weak quirk but has an unwavering determination to prove that they can be a great hero, just like their idols from the previous generation.
Izuku Midoriya could be a main character. His determination and growth throughout the series would make him a great fit for facing kaiju. He could use his One for All quirk in creative ways to fight the huge monsters, perhaps by focusing the power into a single, super - strong punch that can knock a kaiju off its feet.
The kids themselves could be the main characters. There could be a group of them with different quirks. One might be a shy kid with a telekinesis quirk, another a bold child with a fire - based quirk. Their interactions and how they grow together at the daycare could be the focus.
It could be an ordinary civilian who lives in the world of 'My Hero Academia'. Maybe someone who works at a local store near the hero agencies. They witness all the hero - villain battles and are inspired to make a difference in their own way, despite not having any powers.
