Midoriya and Naruto would be an interesting pairing. Midoriya's determination to become a great hero is similar to Naruto's drive to become Hokage. They could learn a lot from each other. Another would be Bakugo and Vegeta. Both are hot - headed and extremely powerful. They might start off as rivals but could end up respecting each other. And then there's Uraraka and Nami. Nami's skills with money and navigation could be useful to Uraraka, while Uraraka's quirk could be handy in combat situations for Nami.
In 'boku no hero academia crossover fanfiction', Todoroki and Gray from 'Fairy Tail' would be a great pairing. They both have ice - related powers, and could exchange techniques. Also, All Might and Goku. All Might's symbol of peace status and Goku's love for fighting for good could create an interesting dynamic. A third interesting pairing could be Momo Yaoyorozu and Edward Elric. Momo's ability to create objects from her body could be combined with Edward's alchemy knowledge in some really creative ways.
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.
Definitely Bakugo Katsuki and Renji Abarai. They're both hot - headed characters. Bakugo's explosive Quirk and Renji's powerful sword skills could lead to some intense battles and training sessions together. They might start off as rivals but eventually learn to respect each other. And then there's Todoroki Shoto and Toshiro Hitsugaya. They both have a sort of cold and controlled demeanor. They could compare their ice - based powers and learn new ways to use them, and also share their experiences of growing up with difficult family situations.
Tanjiro and Deku would be a very interesting pairing. Tanjiro has his strong sense of justice and his skills as a Demon Slayer, while Deku is determined to become the greatest hero. They could learn a lot from each other, like Tanjiro teaching Deku about perseverance in the face of great odds, and Deku showing Tanjiro how to better analyze an opponent's abilities.
Deku and Shepard would be an interesting pairing. Deku is a young hero - in - training with a lot to learn, and Shepard is an experienced leader. Shepard could mentor Deku, and Deku could show Shepard the power of having a quirk. Their different backgrounds and skills would make for great character development.
Reincarnating as Midoriya but with some changes in his quirk manifestation could be fascinating. For instance, what if instead of getting One for All in the normal way, the reincarnated Midoriya discovers a different way to unlock and use the quirk? This could lead to a whole new set of adventures and challenges, and also a different dynamic with the other characters.
I think Bakugo and Rock Lee would make for a fascinating pairing. Bakugo is loud and brash, while Rock Lee is extremely dedicated. Rock Lee could show Bakugo the value of hard work without relying on a natural - born power (since Bakugo is very proud of his quirk). In return, Bakugo could teach Rock Lee some new combat tactics. Also, Hinata and Uraraka would be a cute pairing. Hinata's shy but strong nature and Uraraka's bubbly personality could create some really interesting interactions, and they could also learn from each other's combat abilities in their respective worlds.
Definitely Midoriya and Spider - Man. They are both young heroes with a strong sense of justice. Midoriya is constantly learning to control his powerful quirk, and Spider - Man has to deal with the great responsibility that comes with his powers. They could learn a lot from each other about being a hero and handling difficult situations.
One idea could be a crossover with 'One Piece'. The heroes from 'boku no hero academia' could end up on the Grand Line and have to deal with pirates while also using their quirks. Another is a crossover with 'Naruto'. Maybe the students of UA could train with the ninja in Konoha, learning new skills and sharing their quirk knowledge. A third could be a crossover with 'Attack on Titan', where the heroes have to face the Titans and figure out how to use their quirks to defeat these huge threats.
Another popular pairing might be Usopp and Mineta. Usopp's creativity with his gadgets and Mineta's rather unique quirk could create some interesting and comical interactions. They could get into all sorts of wacky adventures together in the fanfiction world.
