Well, apart from the obvious of Harry himself having a different personality due to his new parentage, there could be new teachers at Hogwarts. They might be there to guide Harry in understanding his connection to Rhea. Or perhaps there are some dark characters who are after Harry because of his unique heritage. These new characters would add more depth and complexity to the story, making it more than just a simple re - imagining of the Harry Potter series.
In this fanfiction, we might see new versions of existing characters too. Hermione and Ron might have different relationships with Harry. But the really interesting characters could be those from the world of Rhea. There could be a character who is a messenger of Rhea, constantly guiding Harry on his journey. And there could be antagonists who are jealous of Harry's connection to Rhea or want to use it for their own dark purposes. All these characters would make the fanfiction a rich and engaging read.
In this fanfiction, since Harry is the son of Rhea, it may involve a lot of world - building that combines the Harry Potter universe with elements related to Rhea from mythology. His backstory would be completely rewritten. Instead of the Dursleys, he might have been raised in a different environment influenced by Rhea's nature. His friends at Hogwarts could react differently to him, knowing his new heritage. And the plot could revolve around him uncovering the secrets of his new identity and how it ties into the overarching battle against the dark forces in the wizarding world.
There might be. If Harry is the son of Erebus, perhaps there are new characters related to Erebus' side of the story. Maybe some dark entities that are either trying to help or harm Harry because of his connection to Erebus.
Yes, of course. Besides Harry Potter himself, there might be new characters created specifically for this fanfiction. For example, there could be a mentor - like figure who knows about Harry's 'Son of Doomsday' identity and helps him understand his powers. Or there could be antagonists who want to use Harry's power for their own evil purposes, like a dark wizard who believes that by controlling Harry, he can bring about the doomsday and reshape the wizarding world according to his own desires.
Obviously, Naruto would be one of the main characters since it's in the title. And Rhea, as his supposed mother in this fanfiction. There might also be other characters from the Naruto universe like Sasuke, Sakura, and Kakashi who could play important roles in the story, perhaps reacting to Naruto's newfound relation to Rhea.
Yes, there are quite a few. You can start by looking on popular fanfiction websites like Archive of Our Own or FanFiction.net. Just search for 'Percy son of Rhea and Chaos' and you'll find a variety of stories. Some might focus on Percy's new powers and how he adjusts to being the son of such powerful entities, while others could explore his relationships with other characters in this new context.
There could be. Since it's fanfiction, the author might introduce new characters related to the concept of soulfire. For instance, a mysterious old wizard who is an expert on soulfire and guides the main characters. Or a young witch who has an innate connection to soulfire and uses it in unique ways to solve problems in the wizarding world.
Since it's fanfiction, the author could introduce some really unique characters. There might be a magical creature living in or near the birch. Maybe a sprite or a small fairy - like being that befriends Harry and helps him in his adventure related to the birch.
Yes, there could be. Fanfiction often takes creative liberties and might introduce unique dwarf characters. For example, a dwarf could be a magical creature with special powers in a hidden corner of the wizarding world in some fanfic. They could have their own culture, traditions, and perhaps be involved in some kind of mystery or adventure related to the main plot of the Harry Potter universe.
There might be. For example, if Voldemort discovers Harry's connection to Osiris, he could try to use it against him in some way. Maybe he tries to steal Harry's powers related to Osiris, which could be a huge plot twist.
Maybe. One possible plot twist could be that Harry's connection to Starfire is hidden until a crucial moment, and when it's revealed, it completely changes the way everyone in the wizarding world views him.
