A cool plot could be that the Super Sentai powers are introduced into the MHA world as a new type of quirk. Some characters get these powers and form a new kind of hero team. But there are those who oppose this new form of heroics, thinking it's too flashy or not in line with the traditional quirk - based hero system. This would create conflict and drama within the story.
One idea could be a crossover where the heroes from My Hero Academia team up with the Super Sentai. They could face a common enemy that has powers combining the quirks from the MHA world and the mecha - like threats from Super Sentai. For example, a villain who can create quirk - enhanced giant robots.
A more complex plot could involve a villain from My Hero Academia somehow finding a way to disrupt the Smash Bros world. Maybe they manage to corrupt the power - up items, causing chaos during battles. The heroes from both universes then have to team up to stop this threat. For example, Deku could team up with Mario to figure out how to reverse the corruption and restore order.
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.
Definitely Deku and the Red Ranger. Deku's determination and growth as a hero in MHA would pair well with the leadership qualities often associated with the Red Ranger. They could learn from each other's ways of fighting and inspire their respective teams.
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.
