A great plot for My Hero Academia fan fiction is exploring the backstories of the teachers. What if Aizawa had a secret mission during his early hero days that changed his view on heroics? Another idea is to create an alternate universe where quirks are reversed. So, someone like Bakugo who has an explosive quirk now has a quirk that absorbs explosions. Also, you could write a story about a new student with a really strange and powerful quirk that no one understands, and they struggle to fit in while also being a target for villains.
For My Hero Academia fan fiction, you could write about a world where quirks suddenly start disappearing. Izuku and his friends have to find out why and how to stop it. Or perhaps a story where a villain reforms and tries to become a hero but faces a lot of prejudice from both sides. And then there's the idea of a quirkless person inventing a device that can mimic quirks, causing chaos in the hero - villain dynamic as now anyone could potentially be a threat or an ally.
One idea could be to explore the backstory of a minor character. For example, what was the life of a random student in Class 1 - B like before coming to U.A. High? Another could be a 'what if' scenario, like what if Izuku Midoriya didn't get One For All. Maybe he'd develop his own unique quirk through sheer determination and hard work. Or a fanfic could focus on the villains' side, showing how they came to be and their motives in more depth.
One plot idea could be a villain who is secretly a double agent, working for the heroes all along. They infiltrate the villain group and gather information. Another idea is a hero who loses their quirk and has to rely on their wits and combat skills alone, like Batman in the DC universe. And a villain - hero team - up to face a greater threat that neither can handle alone.
An interesting plot could involve an anti - hero who has a hidden agenda that is not entirely evil but also not in line with the traditional hero goals. Maybe they are trying to expose a corrupt part of the hero society from within. They could form alliances with some villains who also have a vendetta against the corrupt elements. This would create a complex web of relationships and moral dilemmas.
One popular plot idea is the 'lost in another world' scenario. Spider - Man could end up in the world of My Hero Academia, confused about the different rules regarding Quirks and heroes. He'd have to figure out how to get back home while also dealing with the local villains. Another is the 'training exchange'. Peter Parker could visit UA High School to train with the students there, sharing his combat techniques and learning about Quirks in return.
One idea could be to explore an alternate universe where the quirks are reversed. For example, heroes have what are considered villainous quirks and vice versa. This would completely change the dynamics of the story and the relationships between characters.
One idea could be a crossover where the students from Little Witch Academia visit UA High. They could participate in a joint training exercise. The witches could use their magic in creative ways during combat scenarios, while the heroes-in-training show off their quirks. It would be a fun mix of different powers and personalities.
A more relaxing plot could be a beach vacation where the characters just unwind. They could build sandcastles, have picnics, and share stories. But of course, there could be some small challenges like dealing with a sudden rainstorm or a seagull stealing their food.
A great plot idea could be Shinsou going undercover in a villain organization. Since his quirk is so useful for deception, he could infiltrate and gather intel. Or perhaps a story where Shinsou has to train a group of new students with difficult - to - control quirks. He'd have to use his own experiences and his mind - control quirk in a mentoring way. Also, a plot where Shinsou discovers a new aspect of his quirk during a life - or - death battle, which gives him an edge and changes the course of the fight.
One idea could be a mystery in the dorms. For example, strange things start happening like items going missing or strange noises at night. The students could team up to solve it, using their different quirks in the process. Another plot could be a friendly competition between the dorm floors, like a quirk - based Olympics. This would show off their abilities and also strengthen the bonds between the students.
A fanfiction could focus on a special training exercise that goes horribly wrong. For example, a new type of quirk - suppressing technology is used during training, but it malfunctions and Class 1A has to rely on their non - quirk skills to survive and rescue each other. It would show their growth and teamwork in a different light.
