Well, Percy is the central character. There could be a wise old man in the new neighborhood who becomes Percy's mentor. And also a group of kids that Percy initially has a hard time getting along with but later they become his friends. These characters would all contribute to the story of Percy moving away and how he copes with the change.
Obviously Percy would be one of the main characters. And there could be a new friend he makes in the new place, let's say a girl named Lily who helps him explore the new town.
Percy is the main one for sure. But there might also be an antagonist, like a bully in the new school who gives Percy a hard time. And there could be Percy's parents who play a role in the decision of him moving away and also support him from afar.
Well, perhaps Percy moves to a new town and has to start at a new school. He might struggle to make friends at first, feeling like an outsider. Then he could meet someone who changes his perspective and helps him fit in.
Obviously, Harry would be one of the main characters. But there could also be new characters that the author creates for the story. Maybe there's a wise old wizard who takes Harry under his wing in the new place he moves to.
Obviously, Percy would be the main character. But there could also be his friends who might be trying to find him after he runs away. For example, Annabeth could be a major character in the story as she would be worried about Percy and use her intelligence to track him down.
There could be new characters introduced in this fanfiction. For example, a local wizard in the place where Harry moves to could become a main character. This wizard could initially be suspicious of Harry but later become his friend. Also, a magical creature that Harry befriends in his new location could be a central figure. It could help Harry adapt to his new surroundings and teach him things about the local magic that he didn't know before.
Obviously, Percy is one of the main characters. He's the one who is moving in with the Chases. And the members of the Chases family are also main characters. We don't know exactly who they are yet, but they are the ones who will be interacting with Percy in this new living situation.
The main antagonist could be some dark wizards who want to use the dragon for their evil purposes. They might be after the dragon's scales, which are valuable in making powerful dark magic items, or its fire, which can be harnessed for destruction. They would oppose Hermione's attempt to move the dragon away as it would thwart their plans.
Obviously, Percy is one of the main characters. His friends like Annabeth might also be important as they could be the ones trying to find and rescue him.
There could be his best friend Grover. Grover might try to find Percy after he runs away, adding an element of search and rescue to the story.
The main characters are clearly Annabeth and Percy. Annabeth is known for her intelligence and strategic thinking, and Percy for his bravery and water - related powers.
Obviously, Percy would be the main character. There could also be some characters from the original Percy - related universe who might make an appearance to help him adjust or just to check on him. And from the Forks side, characters like Bella or Edward (if it's in the Twilight - Forks setting) could potentially cross paths with Percy. Maybe they become friends or foes depending on how the story unfolds.
