Gray and Weisz would be an interesting duo. Gray's ice - make magic and Weisz's Ether Gear inventions could create some unique combinations. For instance, Weisz could create a device that enhances Gray's ice - make magic, or Gray could use his ice to cool down some of Weisz's overheating inventions. Their personalities, with Gray being the cool and collected type (most of the time) and Weisz being the enthusiastic inventor, would also lead to some fun interactions.
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.
Natsu and Shiki would make an interesting pairing. Natsu is all about brute force and his dragon slayer magic, while Shiki has his gravity powers. They could have some epic battles together against powerful foes, and also learn from each other's determination and will to protect their friends. Their different personalities, Natsu's hot - headedness and Shiki's more laid - back nature, would create some great comical and tense moments.
I think Natsu and Ruby would be an interesting pairing. Natsu is all about brute force and his love for fighting, and Ruby has her own determination and speed. They could learn from each other's combat styles. Ruby could show Natsu how to be more strategic with his attacks, while Natsu could teach Ruby how to be more fearless in the face of danger.
Definitely Spiderman and Natsu. Natsu's brash and fiery personality would contrast with Spiderman's more responsible and cautious nature. They could have some great banter while fighting side by side.
Another cool pairing could be Sakura and Erza. Sakura is a strong female ninja with her own set of skills, especially in medical ninjutsu. Erza is a powerful and fearless mage in Fairy Tail. They could bond over their strength and leadership qualities. Erza could teach Sakura some combat techniques from the world of magic, while Sakura could share her knowledge of healing with Erza.
A really interesting pairing could be Makoto Naegi and Natsu Dragneel. Makoto, with his positive and determined attitude, could befriend Natsu easily. Natsu's impulsiveness and Makoto's more level - headed thinking could create an interesting dynamic. They could team up to face challenges, with Makoto providing the strategic thinking and Natsu the brute force.
Inuyasha and Natsu would be a very interesting pairing. Inuyasha is a half - demon with his own set of powers and a bit of a rough - around - the - edges personality. Natsu is a powerful dragon slayer with a hot - headed and passionate nature. They could start off as rivals, constantly trying to one - up each other in terms of strength and ability, but then gradually become friends as they face common enemies. Another interesting pairing could be Kagome and Lucy. Kagome has her spiritual powers and comes from a different time, while Lucy is a celestial wizard. They could bond over their different magical abilities and their strong wills.
Spyro and Natsu would be an interesting pairing. They both have a connection to fire. Natsu is a fire dragon slayer, and Spyro can breathe fire. They could have some epic battles together or team up against a powerful fire - based enemy. Another interesting pairing could be Spyro and Lucy. Lucy has her celestial spirits, and Spyro's otherworldly nature could add an interesting dynamic to their interactions.
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.
