Kirby and Natsu would make a great pair. Natsu's fire - based magic and Kirby's ability to absorb and copy abilities could create some really cool combat combinations. They could both be hot - headed in their own ways and charge into battles without much hesitation.
There could be a fanfiction where Kirby's world and the Fairy Tail world collide in an unexpected way. Maybe some of Fairy Tail's magic starts to affect Kirby's planet, and he has to figure out how to deal with it. This could involve him teaming up with Natsu and the others to restore balance. For example, Kirby could learn some basic magic from the guild members and combine it with his own powers for a new kind of attack.
Well, there could be pairings like Kirby and Happy. They are both cute and friendly characters, and fans might like to imagine them as friends or even partners in some adventures. Happy could fly Kirby around in the Fairy Tail world, and Kirby could protect Happy with his powers.
One interesting concept could be a crossover where Kirby characters gain the magic abilities of Fairy Tail wizards. For example, Kirby could learn Natsu's Fire Dragon Slayer magic and use it in his battles.
It adds more content. The official Fairy Tail series has a limited number of episodes and chapters. Fanfiction fills in the gaps. For example, it can create stories about what the characters were doing during the time - jumps in the original story.
If Lucy never joined Fairy Tail, the friendships and relationships among the characters would form in a very different way. Also, many of the story arcs might not unfold as they do in the original plot.
One popular theme is alternate universes (AUs). Writers like to explore what would happen if the Fairy Tail characters were in different settings, like a modern - day high school or a steampunk world. Another common theme is romance. Fans often pair up their favorite characters in different relationships, such as Natsu and Lucy or Gray and Juvia.
Erza and Jellal are also a favored couple in Fairy Tail fanfiction. Their complex past, with Jellal's redemption arc, adds a layer of depth to their potential relationship. It allows for stories that deal with forgiveness, love that overcomes past wrongs, and the growth of their connection over time. There's also Gajeel and Levy, as their interactions in the series suggest a budding relationship that can be elaborated on in fanfics.
You can try websites like FanFiction.net or Archive of Our Own (AO3). FanFiction.net has a large collection of Fairy Tail fanfics. Just search for 'Fairy Tail' in the search bar, and you'll get a bunch of results. AO3 also has high - quality fan works, and it often has more in - depth and unique takes on the Fairy Tail universe.
The condition could be that the main character has to give up their magic for a period of time. This would create a lot of interesting plot twists as they'd have to rely on their wits and the help of their friends in the Fairy Tail guild instead of their magical abilities.
