A cool plot for My Hero Academia Heroes of Tomorrow fanfiction could be that there's a quirk - based disease that starts affecting heroes and students. The main characters then have to find a cure while still maintaining order in the hero society. Also, a plot where the heroes are transported to a parallel universe where the roles of heroes and villains are reversed could be really interesting. They would have to figure out how to get back while also dealing with this new and strange world.
One idea could be a role - reversal. The villains are suddenly given the chance to be heroes for a day and the heroes have to act as villains. It would be interesting to see how they adapt to the opposite roles.
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.
A fun plot might be a chibi - sized adventure where the heroes get shrunk by accident and have to navigate through a regular - sized city. They would face challenges like crossing the street without getting stepped on, and trying to communicate with normal - sized people. This could lead to some really hilarious and heartwarming interactions.
