There could be some original characters created specifically for the fanfiction. Maybe an old wizard or witch who is the keeper of the secrets of Harry's royal family. Additionally, characters like the Malfoys might be more prominent as they could either oppose or try to manipulate Harry's royal situation for their own gains. And we can't forget Hagrid, who might have some knowledge about Harry's past that he has been hiding all along.
Obviously, Harry Potter himself is a central character. Then there might be characters like Dumbledore who could play a role in guiding Harry about his royal heritage. Hermione would also be involved, perhaps helping Harry research his family history. Ron could be there for moral support and also be part of the adventures that come with Harry's new - found royal status.
Some fanfictions might bring in characters from other wizarding cultures or regions that are related to Harry's royal heritage. For example, a powerful wizard from a far - off land who comes to claim Harry as part of their royal family. Or a group of witches who have been protecting the secrets of Harry's royal bloodline for centuries and now need his help in some way.
Harry Potter himself is often a central figure. Writers might explore how his life changes if he discovers he has royal blood. Hermione Granger could also be involved, perhaps using her intelligence to help uncover the secrets of the royal bloodline.
Harry Potter himself is of course a common character. Since it's about his royal inheritance, he's at the center of the story. Hermione and Ron are also likely to be involved, as they are Harry's closest friends. They might help him figure out the details of his inheritance or protect him from those who would try to harm him because of it.
Hermione Granger is also a common character. Given her love for knowledge and her skills in magic, she would likely be researching the best spells and magical theories to make the terraforming successful. She might be the one to find ancient spells that are crucial for the process.
In many expelled Harry Potter fanfictions, the Weasley family as a whole gets involved. Molly Weasley would be worried sick about Harry and would be cooking up plans to get him back. Fred and George might use their prank - making skills to expose the truth behind the expulsion. Ginny, being Harry's love interest in the original series, would be actively involved in trying to clear his name. And don't forget about the Hogwarts professors. McGonagall would probably be torn between following the rules and believing in Harry.
Harry Potter himself is often a central character. He might be shopping for new school supplies at Flourish and Blotts or looking for a new broomstick at Quality Quidditch Supplies. His friends, like Hermione and Ron, usually accompany him. Hermione might be more interested in books and rare magical artifacts, while Ron would be eyeing the latest Quidditch gear.
Mrs. Weasley is a very likely character. She's an expert at cooking and baking in the normal wizarding world, so in fanfiction about magical bakes, she could be teaching the younger characters how to make special bakes. Hagrid might also be involved. He could bring in some really strange ingredients from the Forbidden Forest, like giant acorns, to be used in the bakes.
Hermione Granger is often involved. In some fanfictions, she discovers hidden conspiracies within the Hogwarts library. For example, she might find a book that reveals a plot by some of the older pure - blood families to keep certain magical knowledge from half - bloods and Muggle - borns.
In addition to the main characters related to Naruto directly, some fanfictions might include other village elders or shinobi who knew about the Uzumaki clan's past. For instance, an old ninja who was friends with Kushina's parents could surface with crucial information about Naruto's heritage. There could also be antagonists who are interested in Naruto's newly discovered heritage for their own evil plans.
New original characters are also common. These are characters created by the fanfiction authors who might be the sole heir to a long - lost inheritance of a royal creature. They could be an ordinary wizard at first, but then find out they have a connection to a powerful and mysterious royal creature like a basilisk. Their journey to understand and embrace this inheritance forms the main plot of the story.
Some fanfictions might explore how Harry's royal heritage affects his relationships with other characters. For instance, it could create tension with the pure - blood families who see him as a threat to their own status. Or it could lead to new alliances with characters who are interested in using his royal connections for their own purposes.
