There's also 'Fairy Tail Warriors in RWBY'. In this fanfic, the Fairy Tail guild members find themselves in the RWBY universe. It shows their struggle to adapt to the new environment and how they use their magic to help the RWBY characters in battles against Grimm. It has some really cool fight scenes where the different powers collide.
People like seeing how the characters from both series interact. For example, seeing how Ruby's Crescent Rose would compare to Erza's swords in a fight. Or how Weiss's Glyphs could work with the Fairy Tail mages' magic. These crossovers allow for some really creative and unexpected interactions that fans enjoy exploring.
Another plot could involve a magic - based tournament where teams from both Fairy Tail and RWBY participate. This would allow for battles between different characters, like Natsu from Fairy Tail facing off against Yang from RWBY. The different fighting styles and power sources would make for exciting match - ups and also a chance for the characters to learn from each other.
I think Natsu and Ruby would be an interesting pairing. Natsu is impulsive and powerful with his fire magic, while Ruby is young and enthusiastic with her scythe skills. They could bond over their love for adventure and their desire to protect their friends. They might also learn new ways to fight from each other, like Natsu learning about Ruby's speed and Ruby learning about Natsu's raw power.
One great 'Fairy Tail watches RWBY' fanfiction is 'The Crossover Experience' on FanFiction.net. It has an interesting plot where the characters from Fairy Tail are magically transported to the RWBY world and their interactions are really fun to read.
They might be really intrigued. Ruby, being the adventure - loving type, would probably be excited to see the magical and action - packed stories in Fairy Tail fanfiction. Weiss might be a bit critical at first, but could come to appreciate the creativity. Blake would be interested in the different characters' backstories, and Yang would enjoy the battles and the strong - willed characters.
I really like 'RWBY in Fairy Tail'. It has great character development as the RWBY girls try to adapt to the Fairy Tail world. Another one is 'Fairy Tail Meets RWBY', which has some exciting battle scenes where characters from both series team up.
One idea could be a crossover where the characters from Fairy Tail and RWBY team up to fight a common enemy. For example, they could face a powerful dark mage who has the ability to manipulate Grimm. The Fairy Tail mages could use their magic, while the RWBY teams use their weapons and semblances in an epic battle.
If RWBY reads Fairy Tail fanfiction, they could have different reactions. Ruby, with her love for adventure, would be drawn to the epic quests in the fanfiction. She might start daydreaming about going on similar adventures with her team. Weiss, being the more refined one, could analyze the writing style and how the Fairy Tail magic system is presented. Blake may empathize with some of the outcast characters in the fanfiction, given her own past. Yang, on the other hand, would enjoy the humor and the over - the - top action scenes, and it could even influence her fighting style a bit, making it more flamboyant.
In some fanfics, the magic from 'Fairy Tail' is introduced to the world of 'RWBY'. This can lead to really cool battles where the RWBY characters have to adapt to new types of powers. For example, Ruby might encounter a Fairy Tail mage who can control fire, and she has to figure out how to fight against that new threat.
