Bakugo could be an interesting character to focus on in an alternate universe. For instance, if he was born without his explosive quirk but instead had a quirk that made him extremely empathetic. This would turn his whole personality upside down. He would go from being the hot - headed, aggressive character we know to someone who is more calm and understanding. It would be interesting to see how he interacts with the other characters in this new state and how he builds his relationships without relying on his strength.
Midoriya is always a great choice. In an alternate universe, say he never met All Might and didn't inherit One For All. He might have to find his own way to be a hero, perhaps by developing a unique quirk - enhancing technology. This would show his determination in a different light. Also, an AU where Midoriya is a villain could be fascinating. We could see how his intelligence and analytical skills would be used for evil, which would be a complete contrast to his usual heroic self.
Deku would be really interesting. He has such a complex journey in the original series. If he's deaged, he'd have to relearn all the things he's worked so hard to master. His relationship with his quirk, One For All, could be explored in a new way. Maybe he'd struggle more with controlling it as a deaged version. Also, his relationships with his friends and teachers, like All Might, would be different. He'd be more naive and inexperienced, which could create some really engaging storylines.
Uraraka could also be a great focus. Her ability to make things float could have some really unique applications in Wonderland. She might befriend some of the floating objects or creatures there. Also, her kind heart could lead her to try and help the downtrodden characters in Wonderland, like the Dormouse, and in the process, she could learn more about herself and her quirk.
Bakugo would be really interesting. His hot - headed nature could lead to some hilarious situations at the beach. Maybe he gets frustrated with the sand getting in his shoes or is overly competitive during beach games.
Well, in a My Hero Academia alternate universe fanfiction, you could have an AU where quirks are tied to emotions. So when a person is extremely happy, their quirk becomes super powerful, but if they're sad, it weakens. This would add a whole new layer of character development as characters would have to learn to control their emotions to use their quirks effectively. You could also explore an AU where the setting is in a post - apocalyptic world where only those with the strongest quirks have survived, and they are now fighting over the scarce resources left.
Todoroki from My Hero Academia could be really interesting. His dual - quirk nature could have some really cool interactions with the ghoul powers. He could use his ice side to counter the heat - based attacks of some ghouls, or his fire side to fend off cold - blooded ghouls. His complex backstory could also add depth to a story set in a crossover world.
First, think about their Saiyan powers and how they would translate in the My Hero Academia world. For example, a Saiyan's ability to increase power level could be like a quirk that gets stronger over time. Consider their backstory, like maybe they're a Saiyan from another planet who ends up in the MHA world. Also, their appearance can combine Saiyan features like a tail and spiky hair with the MHA style of clothing.
I think Deku would be really interesting. He could be sharing his thoughts on how he's constantly trying to improve his quirk and live up to All Might's legacy. His nervous but determined personality would add a lot of charm to the sleepover.
It would probably be Naruto if he's in his godlike state. With his vast chakra reserves and powerful jutsus, he could overpower most characters in the My Hero Academia world. His ability to create countless shadow clones and use techniques like the Rasengan or even more advanced forms would make him a formidable force.
One interesting pairing could be All Might and Captain America. They both represent the ideals of heroism in their respective universes. All Might, with his One For All power, and Captain America, with his super - soldier serum - enhanced abilities, could have great discussions about the responsibilities that come with their powers. They could also train together, sharing their unique combat techniques.
Definitely Deku. His growth from a timid boy to a powerful hero makes it exciting to imagine his further development as an adult. Bakugo is also a popular choice. His fiery personality and his complex relationship with Deku offer a lot of potential for interesting grown - up storylines.
