Wendy is another character. She and Romeo can be portrayed as good friends. They might go on adventures together where Wendy uses her healing magic to keep Romeo safe during battles.
Obviously, Romeo would be the main character. Then there could be characters like Wendy, who is young and has healing magic. Her gentle nature could be an interesting addition to the harem. Another potential character could be Levy, with her intelligence and book - smart magic skills.
Natsu could be one of the main characters. Given his love for food, he might be really interested in an eclair in a fanfiction. He could be on a quest to find the most delicious eclair in the Fairy Tail world. Another could be Lucy. She might use her celestial magic to help in a story related to an eclair, like finding a magical eclair that has been hidden by a celestial spirit.
Natsu is often involved. His powerful fire magic could be a key factor in either trying to stop the destruction or, in some cases, accidentally causing more chaos if his power goes out of control. Gray, with his ice magic, might be there to counterbalance Natsu's heat or work together with him to face the threats.
Wendy is often paired with Chelia in fanfiction. Since they are both Dragon Slayers, their connection in the story can be further developed in fan - made stories. They might go on adventures together or help each other out in tough situations.
Natsu is often a main character. His fiery nature and love for adventure would make him a central figure in any cabin - related story. Lucy might also be featured prominently as she has a close relationship with Natsu and her celestial spirit powers could come in handy in the cabin setting.
Definitely Natsu. He's always getting into trouble with his brash actions, so he's a prime candidate in punishment scenarios. Then there's Lucy. She's new to the guild in a way and still learning the ropes, so she could easily find herself on the receiving end of a punishment. And of course, Makarov, as the guild master, is often involved in doling out or dealing with punishments for the members of Fairy Tail.
Natsu is often a main character in Fairy Tail Woods fanfiction. His adventurous spirit makes him a natural fit for exploring the woods. He might be on a quest to find something powerful or just looking for a new challenge.
The black dragon itself can be a main character. Writers might explore its backstory, its motives, and its personality. It could be a misunderstood creature, or a powerful and menacing force that the Fairy Tail guild has to deal with. In some fanfictions, the black dragon might have a name and a complex history that unfolds as the story progresses.
One of the most commonly paired characters with Romeo is Natsu. Natsu is a very popular character in Fairy Tail, and some fanfiction writers like to explore a yaoi relationship between him and Romeo. Their different personalities, with Natsu being more hot - headed and Romeo being a bit more level - headed at times, can create an interesting dynamic.
Natsu is often paired with Romeo in some fanfictions. Natsu can act as a mentor figure to Romeo, teaching him new fire - based magic techniques. Their interactions can be really exciting as they both have a passion for magic.
