One idea could be reincarnating as a minor villain and trying to reform. For example, using knowledge of the future to avoid getting caught up in big evil plans. Another could be reincarnating as a quirkless student but finding a unique way to be a hero, like developing amazing combat skills without a quirk. Maybe reincarnating as a side character and becoming the mentor to the main heroes, guiding them with knowledge from the original story.
Another plot could be that the reincarnated person has a unique quirk from their past life that is very different from the quirks in the My Hero Academia universe. This could lead to them being both feared and respected. They might have to go through a lot of training to control it and prove that they are on the side of good.
Another plot could be reincarnating as a student in a different class than the main characters. The protagonist then has to work hard to prove themselves and make their own mark in the hero school, while also interacting with the well - known characters in new and unexpected ways. For example, they might form an alliance with a character who was originally an antagonist in the series.
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 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.
Maybe a vampire villain who is trying to turn the heroes into vampires to create an army. The heroes have to figure out how to defeat this villain without getting bitten. They could use their quirks in creative ways, like using a fire - based quirk to repel the vampires.
