I think Mineta and Momo would be a really unexpected pair. Just imagine Mineta in Momo's body having to act in a more ladylike and intelligent way, which would be a huge contrast to his normal perverted self. And Momo in Mineta's body would have to deal with his short stature and his rather... unique personality traits. It would be quite the comical and challenging situation.
Another interesting pair could be Black Widow and Tsuyu Asui. Black Widow is a master spy and assassin, and Tsuyu has her unique Quirk and a very down - to - earth personality. Black Widow could teach Tsuyu some self - defense and espionage skills, and Tsuyu could show Black Widow the importance of teamwork and loyalty within the U.A. High group.
Akko and Deku would be an interesting pair. Akko is full of enthusiasm and determination in her pursuit of magic, much like Deku with his journey to become a great hero. They could inspire each other and learn from their different approaches to achieving their goals.
Definitely Deku and the Red Ranger. Deku's determination and growth as a hero in MHA would pair well with the leadership qualities often associated with the Red Ranger. They could learn from each other's ways of fighting and inspire their respective teams.
I think pairing Deku with Danny from the Game Grumps would be interesting. Deku is all about growth and determination, and Danny has a lot of energy and humor. They could learn from each other, like Deku could teach Danny about heroism, and Danny could show Deku how to relax and have fun sometimes.
Subaru and Izuku would be an interesting pair. Izuku is a born hero with his strong sense of justice and his powerful quirk, while Subaru is someone who has to constantly struggle and rely on his return by death ability. Their different personalities and abilities would create a lot of interesting interactions. Izuku could inspire Subaru to be more confident in his own abilities without relying solely on his special power, and Subaru could show Izuku the value of perseverance in the face of extreme difficulties.
Todoroki is also a popular choice. His complex backstory and powerful quirk make him an interesting candidate for quirk swaps. Swapping his quirk with someone like Momo, who has a creation quirk, could lead to really unique storylines.
The Powerpuff Girls. Blossom, Bubbles and Buttercup in the world of My Hero Academia would be amazing. They could team up with the female heroes like Uraraka and Tsuyu. Their superpowers could combine with the quirks in some really unique battles against powerful villains.
Midoriya and Toga. It's an unexpected pairing because Midoriya is the symbol of hope among heroes and Toga is a rather blood - thirsty villain. But if you think about it, Toga's admiration for heroes could be a starting point. Maybe she could be redeemed or at least have a moment of self - reflection through her interactions with Midoriya.
Naruto and Izuku Midoriya would be a really interesting pair. Naruto's never - give - up attitude and Izuku's growth from a quirkless boy to a powerful hero could create some great interactions. They could learn from each other's experiences and fight side by side against villains.
One idea could be that Midoriya and Bakugo swap bodies. Midoriya, in Bakugo's body, has to deal with Bakugo's explosive temper and reputation among their classmates, while Bakugo in Midoriya's body has to handle Midoriya's self - doubts and insecurities. It would create a lot of comical and also character - developing moments as they try to adapt to each other's quirks and personalities.
