A great fanfiction concept could involve Toshiro Hitsugaya teaching Shoto Todoroki how to better control his ice powers. Since Hitsugaya has great control over his ice abilities in Bleach, he could offer unique insights. Also, a story where the Hollows start attacking the world of My Hero Academia and the heroes have to team up with the Soul Reapers to stop them would be exciting.
One plot idea could be that the heroes from My Hero Academia end up in the Soul Society of Bleach. They could learn about the different spiritual powers there and team up with the Soul Reapers to fight a common enemy, like a powerful Hollows that have somehow invaded both worlds. Another idea is that the Quirks from My Hero Academia start to manifest in the Bleach universe, causing chaos as people with Quirks are not the norm there. And perhaps Ichigo could visit UA Academy and learn about hero training, and even participate in some hero battles.
A cool concept for My Hero Academia fanfiction is to have a time - travel plot. A character could go back in time and change a significant event in the My Hero Academia world. This could lead to a completely different storyline. Or you could write a story centered around a villain redemption arc. For instance, giving a more in - depth look at how a villain like Shigaraki could potentially be redeemed and how the heroes would react to that. Additionally, fanfiction about a tournament between different hero agencies could be really exciting.
One idea could be a crossover where the heroes from My Hero Academia are transported to the Marvel universe. They could team up with the Avengers to fight a common enemy, like a powerful villain who has the ability to steal quirks and superpowers. For example, imagine Deku working alongside Spider - Man, learning new ways to use his quirk from him.
One idea could be a crossover with the Naruto universe. The characters from My Hero Academia could interact with Naruto characters. For example, Deku might learn some new fighting techniques from Naruto. Another idea is a crossover with the Harry Potter world. The students at U.A. could visit Hogwarts and experience magic, while the Hogwarts students could learn about quirks.
Well, you could focus on the social aspects in a My Hero Academia college fanfiction. Maybe some characters struggle to fit in because their quirks are considered odd or too powerful. Or perhaps there are rivalries between different departments, like the combat - focused department and the support department. You could also write about a college event, like a hero - themed sports festival, where the characters show off their quirks in new and exciting ways.
One idea could be that the Autobots and Decepticons arrive in the My Hero Academia world. The heroes could be initially confused by these giant robots with strange powers. For example, Izuku Midoriya might try to understand their technology and powers in relation to his own Quirk. He could see the Autobots' ability to transform as a super - power similar to a Quirk and try to learn from them. The villains in My Hero Academia might team up with the Decepticons for their own evil purposes, leading to epic battles between the combined forces of heroes and Autobots against the villains and Decepticons.
One idea could be a crossover where the characters from My Hero Academia end up in the Sekirei world. They might have to adapt to the rules there, like the Sekirei Plan. For example, Midoriya could befriend some of the Sekirei and try to help them without using their power in a harmful way. Another idea is to have a Sekirei gain a Quirk-like ability, which would be very unique in the Sekirei world and cause all sorts of interesting situations. Maybe a Sekirei with a strength - enhancing Quirk could be a great asset in the Sekirei battles.
One idea could be a story where Eraserhead and Ms. Joke team up on a particularly difficult mission. Maybe they have to infiltrate a villain's lair and their different quirks work in harmony to overcome various obstacles.
One idea could be a story where a character's quirk goes horribly wrong in a very creepy way. For example, if Deku's One For All started to consume his mind instead of empower him, making him lose his sense of self and become a menacing figure. Another could be about a hidden villain within UA who uses their quirk to create disturbing illusions that drive students mad. And a third idea might be a fanfiction where the Nomu are given a more sinister backstory, like they were once normal people whose quirks were brutally experimented on, turning them into the terrifying creatures they are now.
One idea could be exploring the backstories of minor characters during a certain period. For example, how a sidekick trained under a pro - hero before the main events of the series. Another could be a story set during a time when the hero society was in a state of transition, like when new laws about hero work were being introduced.
