A very interesting character to pair Mirio with is Luffy from One Piece in a crossover. Luffy's carefree and determined nature along with his stretching powers would be an interesting contrast to Mirio's Permeation. They could form an unlikely but strong alliance. Another character is Ichigo from Bleach. Mirio and Ichigo could fight side - side against Hollows and other threats, with Ichigo's sword skills and Mirio's hero abilities complementing each other. Also, pairing Mirio with Naruto would be great. Naruto's never - give - up attitude and his use of ninjutsu could create a unique dynamic when combined with Mirio's hero powers.
War would be an interesting character to pair Strife with. They are both from the Darksiders universe, and their different fighting styles and personalities could create some great interactions. For example, War is more brute force while Strife is more agile, and seeing how they work together or clash in a crossover situation would be exciting. Another good pairing could be Dante from the Devil May Cry series. Dante is also a demon - slaying badass, and his cocky attitude might either rub Strife the wrong way or lead to an epic bromance as they take on hordes of demons together.
One interesting character to pair him with could be Loki from the Marvel universe. They both have a knack for trickery and causing chaos. Another option could be the Joker from Batman. Their different styles of madness could create some really wild interactions. Also, pairing him with Alucard from Hellsing would be cool. Roman's human cunning against Alucard's supernatural powers would make for an exciting dynamic.
Midoriya would be a great character to pair Shinsou with. Midoriya's positive attitude and strong sense of justice could complement Shinsou's more reserved and sometimes cynical nature. They could learn a lot from each other, especially when it comes to using their quirks in different situations. Another good pairing could be Bakugo. Their contrasting personalities would create a lot of interesting dynamics. Bakugo's explosive nature and Shinsou's calm mind - control could lead to some intense and humorous interactions.
One popular plot idea could be a crossover with another well - known anime. For example, a crossover with Naruto. Mirio could find himself in the Hidden Leaf Village and have to adapt to the different chakra - based powers while also showing off his Permeation ability. Another idea is a crossover with a superhero universe like the Marvel Universe. He could team up with Spider - Man and learn about different kinds of heroism in that world. A third plot idea could be a time - travel crossover where Mirio travels back in time to the early days of hero society in the My Hero Academia world and has to deal with different rules and villains from that era.
One interesting character to pair him with could be Goku from Dragon Ball. The contrast between Madara's ninja skills and Goku's Saiyan power would make for an exciting dynamic. Another could be Harry Potter. Imagine Madara in the wizarding world, and how he would interact with Harry, who has his own set of powers and a strong sense of justice. Also, Batman would be an interesting match. Batman's strategic mind against Madara's battle - hardened tactics would be a great battle of wits.
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.
Hermione Granger from Harry Potter would be an interesting pair. Hermione is highly intelligent and knowledgeable about magic, while Sabrina has her own unique brand of magic. Their interaction could involve Hermione trying to understand Sabrina's more chaotic magic, and Sabrina learning from Hermione's book - smarts. Another great pairing could be Buffy Summers. As a vampire slayer, Buffy has a different kind of strength and purpose, and her world of demons and vampires would contrast with Sabrina's more traditional witchcraft world.
Nightwing would be an interesting character to pair with Starfire in crossover fanfiction. They have a history in the DC universe, and in a crossover, their relationship could be explored further in new and different settings. Another one could be Spider - Man. The contrast between her alien powers and his more street - level superhero abilities would make for an exciting story.
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.
The Road Runner could be an interesting character to pair with Rango. Their different styles of movement, with Rango being more of a swaggering walker and the Road Runner being super - fast, could create some really fun and comical interactions. Another great pairing would be with Shrek. The contrast between Shrek's ogre - like nature and Rango's lizard self would make for a great story of two misfits coming together.
