Another possible plot is a competition between Superman and the top heroes in My Hero Academia. They hold a friendly, but intense, competition to see who is the most powerful and heroic. This would not only showcase their different powers and abilities but also how their concepts of heroism differ. It could lead to a lot of character development for both sides as they learn from each other.
Superman and All Might would probably have a great deal of respect for each other. They are both symbols of hope in their respective universes. All Might might be a bit in awe of Superman's natural powers, while Superman would admire All Might's determination despite having a quirk that was slowly fading. They could exchange stories about their battles and how they inspire others.
Here's a simple start for a 'prototype My Hero Academia crossover fanfic': In a world where the quirks of My Hero Academia exist alongside the powers from 'prototype'. Alex Mercer finds himself in the middle of Musutafu city. He's confused by the sight of people with all these strange abilities. Izuku Midoriya spots this strange man and approaches him. Mercer, being the shape - shifter he is, tries to blend in but his lack of knowledge about quirks starts causing some misunderstandings. As they interact, Mercer realizes that these 'quirks' could be a new form of power to study, while Midoriya is both fascinated and a bit scared of Mercer's abilities.
One great 'My Hero Academia' crossover fanfiction is the one where they cross over with 'One Piece'. It combines the unique powers of the 'My Hero Academia' world with the adventurous and diverse world of 'One Piece'. The characters interact in really interesting ways, like Midoriya being amazed by Luffy's Devil Fruit powers and Luffy being intrigued by the concept of Quirks.
One idea could be a crossover with the Harry Potter universe. Imagine Deku going to Hogwarts and learning magic while also using his Quirk. He could make friends with Harry and they could learn from each other's skills. Another idea is a crossover with the Avengers. The heroes from My Hero Academia could team up with the Avengers to fight a common, super - powerful enemy. Maybe All Might and Captain America could have an interesting conversation about leadership and heroism.
One idea could be that Kakashi is somehow transported to the My Hero Academia world. He could become a teacher at UA, using his ninja skills and wisdom to train the students in new and unique ways. His Sharingan would be a very interesting power in the MHA universe.
Well, it could be about Ben using his Omnitrix to team up with the heroes from My Hero Academia. Maybe he helps them fight against a new villain that's too powerful for them alone. He could transform into different aliens to use various powers in the battles.
First, choose the characters from both universes carefully. Decide which ones will interact and how. For example, you could start with Bakugo from My Hero Academia ending up in New York City from the Marvel universe. Then, create a conflict. Maybe a villain from Marvel, like Loki, is causing trouble and Bakugo's explosive quirk can be both a problem and a solution in this new world. Don't forget to add some character development. Bakugo could learn about teamwork from the Avengers, which is something he struggles with in his own world.
Well, it could be amazing. Picture Deku from My Hero Academia suddenly in the Marvel universe. He might be confused at first but then start to adapt. He could meet Spider - Man and learn new ways of using his quirk. Maybe they'd team up to fight a common villain like Doctor Octopus who has somehow made his way into the My Hero Academia world too. There are so many possibilities for crossovers between the unique powers in My Hero Academia and the well - known heroes and villains of Marvel.
