Sasuke and Grant Ward would be an interesting pair. Sasuke has his dark past and his thirst for power, and Ward also has a complex and somewhat dark past. They could either become rivals, constantly trying to outdo each other in terms of combat skills and power, or they could find some common ground and work together in a strange way, like using Sasuke's Sharingan and Ward's combat training to take on a powerful enemy.
Daisy Johnson from Agents of SHIELD and Oliver Queen from Arrow would also be an interesting duo. Daisy has her Inhuman powers and combat skills, while Oliver is an expert archer and martial artist. They could fight side - side in a big battle against a powerful villain.
Definitely Harry Potter and Daisy Johnson. Harry has his magic skills and experience in fighting dark wizards, while Daisy has her Inhuman powers and combat training. They could learn a lot from each other. Harry could teach Daisy about different magical spells and Daisy could show Harry some of her cool combat moves. Their personalities are also quite different but in a way that could lead to great character development and an interesting dynamic in the story.
Naruto and Tsukune would be an interesting pair. Naruto's energetic and determined nature combined with Tsukune's kind heart and his own growth as a character in the Rosario world could lead to some great interactions. They could learn from each other's ways of dealing with challenges and protecting their friends.
Definitely Captain America and Agent Coulson. Captain America represents the old - school heroism of the Avengers and Coulson is the heart and soul of Agents of Shield. Their different leadership styles and moral compasses would create a great dynamic. They could learn from each other, like Coulson teaching Cap about modern technology and Cap teaching Coulson about the values of the past.
Naruto and Bill Compton could be an interesting pair. Naruto's naivete and his strong sense of justice combined with Bill's more jaded view of the world and his vampiric powers would create an interesting dynamic. They could be forced to work together to solve a mystery that involves both the ninja world and the vampire world.
Harley Quinn and Sakura could be a great match. They are both strong female characters with very different personalities. Harley's wild and unpredictable nature could either drive Sakura crazy or inspire her to be more free - spirited. And Sakura could teach Harley some self - defense skills beyond just her acrobatics and baseball bat - swinging.
Sasuke and Dimitri would be a great pairing. Both are strong, brooding characters with a lot of depth. They could have some intense sparring sessions where they exchange fighting techniques. Dimitri could introduce Sasuke to the world of vampires and the complex politics involved, while Sasuke could share his knowledge of ninja jutsu and the shinobi way. Their similarities and differences would make for a very engaging relationship in the fanfiction.
I think Naruto and Lucifer would be an interesting pair. Naruto's unwavering belief in good and his never - give - up attitude would contrast sharply with Lucifer's more cynical and self - centered nature. Their interactions could be full of tension and also moments of mutual understanding as they learn from each other.
Naruto and Kaneki would be a really interesting pair. Naruto is all about hope and never giving up, while Kaneki has this internal struggle between his human and ghoul sides. Naruto could help Kaneki embrace his duality more positively and Kaneki could show Naruto the darker side of a world where survival is not as straightforward as in the ninja world. Their different powers, Naruto's chakra and jutsu and Kaneki's kagune, would also make for some exciting battle scenes and strategic combinations.
Sasuke and Papi could be a fun pairing. Sasuke's brooding and serious demeanor would be quite different from Papi's carefree and somewhat ditzy nature. Papi's ability to fly could be useful in Sasuke's missions, and Sasuke could teach Papi some self - defense ninja moves. Their interactions would be full of comical moments as well as some deeper exchanges as Sasuke tries to understand Papi's simple - minded yet kind - hearted way of thinking.
