There could be a fanfiction where Goku is a long - lost relative of a powerful Fairy Tail wizard. In this story, he discovers his family ties while also having to face off against a common enemy that threatens both his Saiyan heritage and the Fairy Tail guild. He would bring his Saiyan strength and tenacity to the battles in the Fairy Tail world.
A cool fanfiction idea might be that Goku is summoned to the Fairy Tail world by a dark magic spell gone wrong. At first, the Fairy Tail members are scared of his power, but then they realize he can be an ally. Goku then helps them train and they all become much stronger, with Goku learning about friendship in the Fairy Tail way which is different from what he has experienced on his own adventures.
One possible plot could be that Goku somehow gets transported to the Fairy Tail world. He could join forces with Natsu and the gang to fight against a common enemy like Acnologia. Goku's power levels would be off the charts compared to most in Fairy Tail, but he'd be intrigued by their magic. Maybe he'd learn some magic himself or teach them some of his ki techniques.
One interesting story could be one that focuses on the character development within the Fairy Tail universe while still having a touch of the unique elements from 'Lemons Fanfiction'. For example, a story about a secondary character getting a chance to shine and their relationships evolving in a way that's not shown in the original series. However, it's important to note that 'Lemons' often implies more adult - themed content, so many platforms may not allow such explicit fanfictions.
One interesting Fairy Tail fanfiction could be about an alternate universe where the main characters have different magic abilities. For example, Natsu might have ice - based magic instead of fire. Another could focus on the backstories of the minor characters in more detail, like how Jet and Droy met before joining Fairy Tail.
A great Fairy Tail fanfiction might be one that gives a different ending to a major arc in the series. Instead of how it ended in the original, it could have a more bittersweet or even a completely different resolution. For instance, in the Tartaros arc, it could end with a different sacrifice or a new way of defeating the demons.
One interesting Fairy Tail fanfiction could be about an alternate universe where the characters have different magic abilities. For example, Natsu might have ice - based magic instead of fire. Another could focus on a romantic relationship between two characters that wasn't explored much in the original, like Levy and Gajeel's relationship in more depth.
Well, one possible plot could be that Goku somehow ends up in the Fairy Tail world. He might initially be confused by the magic there, but then start to learn about it. He could team up with Natsu and the gang to fight against a powerful dark wizard. Goku's strength and his unique fighting skills like the Kamehameha could be a great asset to Fairy Tail in battles.
Erza would also be a good pairing. She is a very disciplined and strong - willed character. Goku could learn from her discipline, and she could learn from Goku's carefree yet determined attitude. They could fight side by side in battles and protect each other.
One interesting Zoro Fairy Tail fanfiction could be one where Zoro from 'One Piece' somehow ends up in the world of 'Fairy Tail' and has to adapt to their magic system. He might start challenging the wizards there to sword fights, which would be really cool to read.
One interesting eclair fairy tail fanfiction could be about an eclair having magical powers in the Fairy Tail world. Maybe it's an eclair that can grant wishes to the mages in Fairy Tail, leading to all sorts of adventures as they try to find it. Another could be a story where an eclair is a key to unlocking a hidden magic within the guild.
There could be a fanfiction where the Fairy Tail members decide to live together in a huge mansion. Lucy might use her celestial spirit magic to help decorate the rooms. For example, Taurus could be used to move heavy furniture around. And they would have all kinds of adventures just within the house, like finding secret passages that lead to different magical realms.
