Definitely Natsu. His popularity in the original series carries over to the fanfiction. He can be put in all sorts of situations, like facing a new super - powerful enemy or having to master a new form of his fire magic. Lucy is also beloved. Her growth as a wizard and her relationships with the spirits can be explored in many ways. And Erza, with her strong - willed and powerful nature, is a favorite too. Writers can create stories around her past battles and how they've shaped her into the person she is in the fanfiction.
One interesting concept could be the exploration of different character backstories. For example, delving deeper into a side character's past that wasn't fully explored in the original Fairy Tail. Another might be unique magic abilities that are created specifically for the fanfiction. It could also involve new relationships between characters, like unexpected friendships or rivalries.
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.
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.
