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

Lucy and Rebecca could also be a great pairing. Lucy is a Celestial Spirit mage, and Rebecca is a B - Cube blogger. Their different skillsets could complement each other well. Maybe Rebecca could use her media influence to help Lucy find some rare Celestial Spirits. And Lucy could protect Rebecca during their adventures with her magic. They could also bond over their relationships with their respective male counterparts in their original series.

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.

Goku and Natsu would be an interesting pairing. Natsu is all about passion and brute strength in his use of fire magic, and Goku has his Saiyan power and love for a good fight. They could have some epic battles together, like sparring to see who's stronger, and also team up to take on tough enemies. They both have a bit of a reckless streak too.

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.

Reborn and Erza. Reborn is a strict and highly skilled hitman - turned - tutor, and Erza is a powerful and disciplined mage. They could have some intense training sessions together. Reborn might be impressed by Erza's combat skills and her ability to lead in battle, and Erza could be intrigued by Reborn's unique teaching methods and his vast knowledge of combat and strategy.

Naruto and Natsu would be a really interesting pairing. Both are hot - headed, determined, and have a strong sense of justice. They would probably start off butting heads but then realize they have a common goal and work well together. Their powers are also quite different, with Naruto's ninjutsu and Natsu's fire dragon slayer magic, so they could combine their attacks in creative ways.

I think Naruto and Lucy would be really interesting. Naruto's brash and determined nature combined with Lucy's more level - headed and strategic thinking could lead to some great interactions. Also, Naruto might be fascinated by Lucy's celestial spirits.

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.

Ben and Natsu would be an interesting pairing. Natsu is all about fire and brute strength, while Ben has the ability to transform into various aliens with different powers. They could have a friendly rivalry, like who can defeat an enemy faster. Ben could show off his alien forms to Natsu, and Natsu could teach Ben some fire - based magic tricks in return.

A Fairy Tail and Edens Zero crossover fanfic can be really exciting. It combines the unique magic systems and characters from both series. For example, characters from Fairy Tail like Natsu with his fire - based magic could interact with Shiki from Edens Zero in interesting ways. Maybe they could team up against a common enemy or have a friendly sparring match to test their powers.
