Midoriya could also be a great focus. He might be more reserved at the beach, but his thoughts and observations could be really interesting. He could be constantly thinking about how to use his quirk in different beach - related scenarios, like saving someone from a riptide.
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.
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.
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.
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.
First, give the character a unique quirk that interacts interestingly with the beach environment. For example, if the character has a quirk related to heat, the beach's hot sand and sun can be used to enhance their power or present challenges like overheating. Then, develop their backstory in relation to the beach. Maybe they had a significant event there as a child. Also, give them a distinct personality trait that stands out on the beach, like being overly cautious about the ocean because of a past near - drowning experience.
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.
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.
Momo Yaoyorozu and Tony Stark. Momo has the ability to create any non - living object she can think of as long as she knows its molecular structure. Tony Stark is a genius inventor. They could collaborate on creating amazing new gadgets and weapons. Momo could provide the raw materials with her quirk, and Stark could use his engineering skills to put them together. It would be a combination of brains and super - powers that could create some really unique and powerful items for the heroes.
I think Uraraka and Green Lantern would be a cool pairing. Uraraka's quirk allows her to manipulate gravity, and Green Lantern's power ring is based on willpower and can create constructs. They could combine their powers in really creative ways. Uraraka could make objects weightless for Green Lantern to use in his constructs more easily, and he could protect her while she focuses on using her quirk.
One interesting pairing could be Izuku Midoriya and Captain America. Izuku is all about the spirit of never giving up and has a strong sense of justice, much like Captain America. Cap could teach Izuku some hand - to - hand combat skills and Izuku could show Cap the potential of quirks. Another cool pairing would be Bakugo and Iron Man. Both are brash and confident in their abilities. Iron Man could help Bakugo upgrade his gauntlets with some Stark tech while Bakugo's explosive personality might give Iron Man some new ideas for his suits.
