It's possible that there's a love interest for Percy in the fanfiction. This character could be another adventurer or someone from Percy's past. Their relationship could add an emotional aspect to the story, as Percy has to balance his feelings for this person with his dangerous job as a dragon slayer.
Typically, the main character is the dragon slayer. They are often a brave and determined individual with unique skills and a strong will.
Since I don't have the actual fanfiction, it's hard to say for sure. But it's likely that the dragon slayer is a main character. There could also be other characters like villagers who are being affected by the situation related to 'the nothing' and perhaps other dragon slayers or mentors.
In some fanfictions, Happy, the flying cat, could also be an important character. He could provide comic relief and also be involved in some of Lucy's adventures as a dragon slayer. For example, he might help her find clues or get out of difficult situations. And then there could be original characters created specifically for the fanfiction. These characters could be other dragon slayers or powerful mages that interact with Lucy in different ways.
Well, Naruto is a must - have main character. He might be the one who unlocks the dragon slayer bloodline's true potential. Hinata could be another main character, her Byakugan ability might interact in interesting ways with the dragon slayer powers. There could also be a mysterious character who is an elder of the dragon slayer bloodline clan. This character could hold the key to understanding the bloodline's history and secrets, and thus be an important main character in the fanfiction.
Well, obviously Lucy is one of the main characters since it's in the title. She's likely to be the central figure around which the story revolves. There might also be other dragon slayers who could be important characters. They could be friends or rivals to Lucy, and their interactions with her would shape the story.
In some fanfictions, there might be original characters created by the author. For instance, a mysterious figure who has some connection to Natsu's multi - dragon slayer abilities. This character could be an antagonist, testing Natsu's skills, or a mentor, guiding him to master his powers better.
Obviously, Natsu is one of the main characters. He is the strongest dragon slayer in this fanfiction. His friends from Fairy Tail like Lucy, Gray, and Erza are also likely to be main characters. They often support Natsu in his battles and adventures.
Well, Naruto is likely to be one of the main characters. Since it's a Naruto - related fanfiction, he'll probably be at the center of the story. There might also be characters from the dragon slayer world that are important, like the typical dragon slayer mages. But without reading it specifically, it's hard to say exactly who all the main characters are.
Percy is the central figure for sure. Alongside him, his dragon is a crucial character. There might also be other characters like Percy's friends or foes. His friends could support him in his dragon - riding adventures, while his foes could try to stop him or steal his dragon. Maybe there are some wise old mentors in the story who teach Percy about dragon riding and its secrets.
Percy Jackson is the central figure for sure. The dragon is another main character, whether it's a friendly or a menacing one. There could be new characters created specifically for the fanfiction. For example, a dragon tamer from an ancient demigod lineage who has knowledge about the dragon's kind. This character could either be an ally or an antagonist to Percy. And of course, we might see some of the minor gods or goddesses make an appearance, as they often have their own interests in the affairs of demigods and magical creatures like the dragon.
