Well, typically the main character would be a fire dragon slayer. They are the ones with the special connection to the fire dragon powers.
Another possible main character could be an antagonist who is after the fire dragon powers for their own evil purposes. They might be a powerful dark mage or a rival slayer who has turned to the dark side. This character would create conflict and drive the story forward as the protagonist tries to stop them from misusing the fire dragon powers.
Wendy Marvell is another important dragon slayer. She's a sky - dragon slayer and her gentle nature and unique powers play a significant role in many fanfiction stories. Her ability to heal and support her comrades is often crucial in battles and in the development of the overall plot.
A really interesting plot would be if the world of the fanfiction was facing a threat that only the fire dragon powers could stop. But the catch is that the current fire dragon slayers have to combine their powers in a way they've never done before. They would have to overcome their differences and learn to work together, all while dealing with the increasing danger to their world.
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.
Obviously, the dragon maiden herself is a main character. She is likely to be a complex character with a lot of depth. There might also be a wizard or a group of wizards from the Fairy Tail guild who interact with her. For example, a powerful mage who becomes her mentor and helps her to control her dragon powers. Another possible main character could be an antagonist, like a dark sorcerer who is envious of the dragon maiden's powers and tries to steal them or destroy her.
I'm not sure who exactly said that. It could vary depending on the specific fanfiction story.
It's hard to say without actually reading it, but it could feature the classic Fairy Tail characters like Natsu, Lucy, Gray, and Erza. They are the most popular and central to the original series.
Gray would also be important. There could be a rivalry - turned - friendship aspect where Gray, who has his own ice - making powers, and Natsu, as a dragon, have to learn to work together. Maybe they compete in a friendly way to see whose powers are more useful in different situations.
Well, obviously Jackal is one of the main characters. But often, you'll also see Natsu Dragneel. Since Natsu is one of the main protagonists in 'Fairy Tail', he often crosses paths with Jackal in fanfiction. Another character could be Lucy Heartfilia. Her celestial magic might play a role in a story involving Jackal, like she might use her magic to help defeat him or understand his motives.
The main character is Rolu, of course. But we could also see Wendy in the fanfiction. Wendy might use her healing magic to help Rolu when he gets injured during a battle. Makarov, the guild master, could also play an important role. He might be the one to give Rolu a chance to prove himself in the Fairy Tail guild, and his wisdom could guide Rolu as he navigates the complex world of Fairy Tail and its various challenges.
Another possible main character could be a new character created specifically for the fanfiction who has a deep connection with Ophiuchus. Maybe they are siblings or have a mentor - mentee relationship. This new character can bring a fresh perspective to the story and help drive the plot forward.
