One possible plot could be that the Omnitrix from Ben 10 somehow ends up in the My Hero Academia universe. Ben could team up with Izuku Midoriya. Ben, using his various alien forms, could help in hero battles against villains. For example, Heatblast could be useful against ice - based villains in the MHA world. And Izuku could learn a lot from Ben's experience in handling different powers and situations.
It could be really exciting. Maybe Ben could use his Omnitrix to transform into an alien with a Quirk - like a combination of his alien powers and a hero's ability from My Hero Academia. For example, he could turn into Four Arms but with super strength enhanced by One For All. The story could involve Ben and the heroes of UA working together to stop a powerful villain that neither could defeat alone.
In a 'Ben 10 My Hero Academia Crossover Fanfiction', Ben Tennyson would be a main character. He has the Omnitrix which is full of possibilities. Another main character could be Ochaco Uraraka. Her gravity - controlling Quirk would be an interesting contrast to Ben's alien powers. They could work together in some really cool ways, like Uraraka using her Quirk to levitate Ben in a strategic way during a battle. And then there's also Tenya Iida. His speed and strict sense of justice would add another dynamic to the group. These characters would all play important roles in the story, whether it's in combat, strategizing, or just in their interactions with each other.
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.
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 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.
All Might and Ben would have a great interaction. All Might, being the symbol of peace in the MHA world, would be intrigued by Ben's powers. He might see Ben as a young hero with a different kind of power set. Ben, on the other hand, would look up to All Might's heroism. Also, Ochaco and Ben could have an interesting dynamic. Ochaco's gravity - controlling Quirk could be used in combination with some of Ben's alien forms in creative ways during battles or rescue operations.
A really fascinating crossover might be where Ben's Omnitrix gets into the hands of a character from My Hero Academia, like Midoriya. Imagine him trying to figure out how to use all the different alien forms and how it would affect his hero training. Or perhaps having Vilgax team up with the League of Villains to take over both universes. This would create a really intense and action - packed story.
One idea could be that Godzilla arrives in the My Hero Academia world during a major villain attack. The heroes initially see Godzilla as a threat but soon realize that he is targeting the same villains who are causing environmental destruction. His massive size and power could be a game - changer in the battle.
I think Ben and Deku would be an interesting pairing. Deku is all about analyzing and strategizing, while Ben has the power of the Omnitrix. Deku could help Ben figure out better ways to use his alien forms in combat, and Ben could show Deku some really out - of - this - world powers.
