Who would be the most interesting character pairings in a 'Fairy Tail' and 'Rick and Morty' crossover fanfiction?

Morty and Brian could be a great pairing. Morty is often the more moral and naïve character in Rick and Morty, while Brian is the somewhat jaded family dog in Family Guy. They could have conversations about life, mortality, and the meaning of existence. Morty might be intrigued by Brian's writing and Brian could be both amused and concerned by Morty's adventures with Rick.

Spiderman and Erza would make for a strong pairing. Erza is a very powerful and disciplined mage. Spiderman could be in awe of her combat skills and leadership. They could fight side - side against powerful enemies, with Spiderman using his webs and agility and Erza with her various armors and weapons.

Yugi and Natsu would be an interesting pairing. Yugi is calm and strategic, while Natsu is impulsive and powerful. They could balance each other out. Yugi could use his intelligence to plan their adventures, while Natsu could use his fire - based magic to fight off enemies. Another interesting pair could be Erza and Kaiba. Erza is a strong and disciplined warrior, and Kaiba is a proud and powerful Duelist. They could have some epic battles of wills and skills.

Natsu and Ziva would make an interesting pairing. Natsu's hot - headedness and powerful fire magic could contrast well with Ziva's cool and efficient combat skills. They could learn from each other in terms of fighting styles and also develop a friendship based on mutual respect.

A pairing between Sakura and Erza would be great. Erza is a strong and disciplined warrior in Fairy Tail, and Sakura has her own strength and tenacity. They could train together and learn from each other's combat styles. Maybe they would compete in friendly sparring matches, which would not only improve their skills but also strengthen their friendship in the process.

Goku and Natsu would be an interesting pairing. Goku's pure - heartedness and love for fighting would mesh well with Natsu's fiery and passionate nature. They could have some epic battles together just for fun, and then team up to take on stronger foes. Another good pairing could be Vegeta and Gray. Vegeta's prideful and somewhat cold demeanor would contrast with Gray's cool - headedness. They could learn from each other's fighting styles, with Vegeta showing Gray some of his Saiyan techniques and Gray teaching Vegeta about his ice - make magic.

Lucy and Eevee could be an interesting pair. Lucy is kind - hearted and Eevee is a very adaptable and cute Pokemon. Lucy could use her celestial keys to help Eevee evolve into different forms depending on the situation they are in. For example, if they need to cross a large body of water, she could help Eevee evolve into Vaporeon.

Lucy from Fairy Tail and Rin from Fate could form an interesting duo. Lucy is a Celestial Spirit mage, and Rin is a skilled mage in her own right. They could bond over their shared love for magic and their determination to protect their friends. They might also exchange knowledge about different types of magic, with Lucy showing Rin her Celestial Spirit magic and Rin introducing Lucy to some of the more unique spells in the Fate universe.

Wanda Maximoff and Juvia would be a fascinating pairing. Wanda's powerful magic and Juvia's water - based magic could create some really unique and powerful combinations. Also, their different personalities - Wanda's more brooding and Juvia's more love - struck - would make for some interesting interactions.

Gray and Weiss could also make a great pair. Gray with his ice - make magic and Weiss with her ice - based semblance could have some really cool interactions. They could compare and contrast their ice powers, and perhaps even combine them in some creative ways during battles. Plus, their personalities are quite different which would lead to some interesting character development moments.
