Obviously, Naruto would be one of the main characters. There might also be his friends like Sasuke or Sakura. Maybe some of the older ninja like Kakashi or Iruka could also play important roles, as they might have knowledge about Naruto's inheritance or be involved in the process of him claiming it.
The main character is Naruto. But we can't forget about characters like Jiraiya. Jiraiya might have known something about Naruto's inheritance and could be guiding him from the afterlife through some sort of message or prophecy. Then there are Naruto's rivals from other villages. They might see Naruto's new - found inheritance as a threat and try to take it from him, so they also become important characters in the story.
In this fanfiction, Naruto might face various challenges while claiming his inheritance. It could involve dealing with hidden secrets about his family, perhaps some sort of special jutsu or a powerful item left behind. Maybe there are other characters who oppose his claim, leading to battles or political intrigue within the Hidden Leaf Village.
Well, Harry is definitely one of the main characters since it's about him claiming his titles. There could also be his friends or allies. If it's in a Harry Potter - like universe, it might be Hermione and Ron who support him in his quest to claim his titles. And then there could be antagonists too, perhaps people who have something to lose if Harry claims his titles, like rival claimants or those who want to keep the power that Harry's titles would bring under their control.
Most likely Harry would be the main character since it's about him claiming his lordship. His friends like Hermione and Ron may also be main characters as they usually support Harry in his adventures.
Most likely, Harry Potter is the central character in 'harry claims his seats fanfiction'. But depending on the direction of the story, it could also feature characters like Draco Malfoy if he is trying to oppose Harry's claim on the seats. Additionally, teachers at Hogwarts such as Professor McGonagall might make an appearance if the seat - claiming incident occurs within the school premises and she has to mediate or enforce rules.
The Malfoys might oppose him. They are always looking for ways to undermine Harry, and if his inheritance gives him more power or status, they would surely be envious and try to stop him.
Well, he might discover some powerful magic items as part of his inheritance. For example, a unique wand or a spell book with long - lost spells.
He might meet other wandering ninjas who are also on a quest for power or knowledge. They could either become his allies or foes depending on their motives.
Naruto himself is often a central figure in these fanfictions. His son or daughter might be the ones inheriting his powers or his legacy. Sasuke is also common, as his skills and story are so intertwined with Naruto's. Hinata could be involved too, especially if it's about the inheritance within the Hyuga clan. And of course, Kakashi, as he has a lot of knowledge and skills that could potentially be passed on to the younger generation.
Artemis and Percy are the main characters. Artemis, being a goddess, has her own motives and personality traits that drive the story. She is known for her independence and her connection to nature and the hunt. Percy, who could be a demigod or some other kind of special being, is the one being claimed. He has his own set of relationships, like with his friends or family perhaps, that could be affected by this new situation. And of course, there could be other minor characters like the gods who might have an opinion on Artemis' actions or other mythical creatures that Percy and Artemis encounter during their time together.
Obviously, Harry is the most important character. Then there might be his friends like Hermione and Ron. They could help him understand and manage his inheritance. There may also be some new characters, like an old wizard who is the keeper of the inheritance until Harry is ready. And of course, the antagonists like Draco Malfoy or any remaining Death Eaters might be interested in his inheritance, either to steal it or to stop Harry from using it to gain more power.
