The main character is Harry, given his immortality is the focus. Ron and Hermione are likely to be main characters too as they are integral to Harry's story. But it's also possible that descendants of other characters become important. For example, if Ginny and Harry had a relationship in the original story, their descendants could have a role. Additionally, there might be ancient magical beings that become part of the story due to Harry's immortality and his new connections to the deeper mysteries of the wizarding world.
In this fanfiction, the main character is a very over - the - top self - insert. They are meant to be this unique and special presence in Hogwarts. Ebony Dark'ness Dementia Raven Way is another major character. She is extremely self - centered and her actions and words are very outlandish. As for the regular Harry Potter characters, they are sort of there to play supporting roles. Harry is there, but he's not the heroic figure we know from the books. Hermione and Ron also have their roles, but they are often used to contrast with the wildness of the self - insert and Ebony characters.
Well, Harry Potter would be at the center. But in addition to his usual friends, some other characters could be main characters as well. For example, Neville Longbottom. He has grown a lot in the original series. In this fanfiction, he could bring his knowledge of herbology to the immortal vacation, maybe using plants in the new vacation place in ways no one has thought of before. Also, Dobby the house - elf could be a main character, as his loyalty and magic could play a big role in the adventures during the vacation.
It could be Hermione. Since she's Harry's close friend, she would likely play a significant role in a story where Harry is immortal. She might be the one trying to help Harry adjust to his new state or be involved in his adventures in some way.
It could be a group of dark wizards who see Percy and Harry's immortality as a threat to their own power - hungry plans. They might try to eliminate them to gain more control over the wizarding world.
Ron Weasley could be another main character. He might be by Harry's side, providing the loyalty and friendship he always has. In some fanfictions, he could also gain some unique abilities or knowledge related to Harry's new state. And Dumbledore, even in death, might still have an influence. His past knowledge and wisdom could be a guiding force for Harry as he navigates his new immortality and power as the Master of Death.
Ash is the central figure in 'ash is immortal fanfiction'. His Pokémon, especially Pikachu, are bound to be main characters too. They are not only his partners in battles but also in his eternal journey. Additionally, there might be new characters created specifically for this fanfiction. Maybe a wise old Pokémon trainer who has some knowledge about Ash's immortality and guides him on certain aspects of his never - ending adventure.
Percy is the central figure in 'percy is immortal fanfiction'. Other characters like Grover might play important roles too. Grover could be worried about Percy's immortality and try to help him come to terms with it. And of course, there could be new characters introduced who are also immortal and interact with Percy in different ways.
Often, Harry Potter himself is a central character. He might interact with immortals and be influenced by their ways. Hermione could also be there, using her intelligence to understand the immortals and their magic. Voldemort could be another common character, and his quest for power might be affected by the presence of immortals. Maybe he tries to gain immortality from them or is in conflict with them because they pose a threat to his plans.
Obviously, Harry is one of the main characters. His two triplet siblings are also central. Depending on the fanfiction, they could be named something unique, like James and Lily (not to be confused with Harry's parents). Then there are the usual Hogwarts characters like Hermione and Ron who interact with the triplets in different ways, sometimes being suspicious at first of the new addition to the group, and other times being quick to accept and help them.
The main characters are Harry and Hannah. Harry is typically depicted as the brave and resourceful hero we know from the books. Hannah can be a new addition to his world. She might be someone who has her own secrets and powers. For example, she could be a seer who can predict future events, and her visions play a crucial role in the story's plot as she and Harry try to prevent disasters or solve mysteries.
