A possible plot is that there is a villain who targets students with complementary quirks like Izuku and Momo. They must figure out the villain's plan and stop them. Along the way, they discover hidden aspects of their quirks. Momo could create a device that helps Izuku control his power better, and Izuku's determination could inspire Momo to be more confident in using her quirk in high - stress situations.
One plot idea could be that Izuku and Momo are paired up for a special training mission. They have to learn to combine their quirks in new and unexpected ways. For example, Izuku's super strength could be used to enhance Momo's creation of large and complex structures. Another idea is a story where they both get trapped in an alternate dimension and have to rely on each other to find a way back. They face various challenges that test not only their quirks but also their friendship and trust in each other.
Well, a fanfiction plot could be that Izuku and Momo enter a school - wide competition. They start as underdogs but gradually develop a strategy that makes the best use of their quirks. Momo creates strategic items for Izuku to use during the battles, and Izuku's quick thinking and bravery give Momo the courage to keep creating useful things. As they progress through the competition, their bond grows stronger.
One plot idea could be Momo using her quirk in a rather obsessive way to create things for her 'beloved'. For example, she could create tracking devices to always know where they are. Another could be her isolating the object of her affection from their friends by using her intelligence and resources. Maybe she creates false threats that only she can protect them from.
One idea could be that Toga, in an attempt to understand Izuku better, tries to live a normal life like him for a while. She disguises herself and enrolls in U.A. High, leading to a series of comical and tense situations as she tries to hide her true identity from Izuku and the other students.
One idea could be that Shoto and Izuku have to team up for a special training exercise that goes horribly wrong. They end up in an unknown part of the forest and have to rely on each other's quirks to survive and find their way back. For example, Izuku uses his One For All to climb tall trees to get a better view, while Shoto uses his ice to create shelters at night.
One possible plot idea could be Izuku developing a new and unique quirk spiral ability that sets him apart from his peers. Maybe it starts as an unexpected mutation of his existing power. Another idea could be Izuku getting caught in a time - spiral within the My Hero Academia universe, where he has to relive certain events to change the outcome for the better. And a third could be Izuku's spiral being related to a spiritual or mental journey, where he discovers hidden aspects of himself and the hero world.
A possible plot could be a school project where Deku and Momo are in a group with some other students. But Deku is struggling with his part of the project, and Momo helps him out. As they work together, they start to understand each other better. Maybe Momo starts to see the true strength in Deku beyond his physical power, and Deku admires Momo's intelligence and quick thinking. This could lead to a deeper friendship and mutual respect in the story.
A more emotional plot could be about Momo facing self - doubt about her quirk's usefulness in combat. Torokie helps her see the real potential. He shares his own experiences of struggling with his quirk at first. They then train together to show Momo how she can be more effective in battles, and this strengthens their bond.
A different plot might be that the yandere is a childhood friend of Izuku who was always in the background. As they grow older and Izuku becomes more involved in the hero world, her yandere feelings surface. She starts to collect mementos of Izuku secretly and becomes extremely jealous of any girl who shows an interest in him, leading to a lot of drama and conflict within their friendship circle.
One idea could be Izuku struggling to control his shadow quirk at first. Maybe it has a mind of its own and he has to learn to cooperate with it. For example, in battles, the shadow could act independently, which might cause trouble but also surprise opponents. Another plot could involve Izuku using his shadow quirk to explore hidden or dark places. Since shadows can reach areas that are hard to access, he could use it for rescue missions or to find secrets in the city.
One idea could be that Izuku's quirk is related to time manipulation. He could use it to slow down time during battles, giving him an edge in combat. For example, he could dodge attacks with ease and plan his counter - attacks carefully.
One interesting plot could be that they are forced to team up for a really difficult mission. During this mission, they start to understand each other's strengths and weaknesses better. Izuku might learn some new combat techniques from Bakugou, and Bakugou could gain a new respect for Izuku's strategic thinking.
