There could be an original character created specifically for this fanfiction. This character might be the one directly affected by the 'ghost of you', and through their story, we get to explore the new ideas and plotlines in this fan - made story.
Hermione might also be a main character. She's known for her intelligence and problem - solving skills. In this fanfiction, she could be trying to figure out the mystery behind the 'ghost of you' phenomenon, using her vast knowledge of magic and lore.
Harry, Ron, and Hermione would be obvious choices as main characters. They already have a lot of experience with magical mysteries and adventures at Hogwarts. Their knowledge of spells and the castle's secrets would be very useful in a ghost hunt. Another option could be the Weasley twins. They are known for their mischievous nature and creativity, which could make for an interesting take on a ghost hunt. They might use their prank - related magic items to track or interact with ghosts in a unique way.
Hermione would likely still be a main character. She would probably be the one trying to research about Harry's half - ghost condition, scouring the library for any information on half - human, half - ghost beings in the wizarding world. She might also be the one to help Harry control his new abilities when they get out of hand, using her vast knowledge of magic.
Since I haven't read it, I can't say for sure. But it's likely to feature Harry Potter, Hermione Granger, and Ron Weasley as they are the central characters in most Harry Potter - related stories. There might also be other characters like the goblins from Gringotts who would be important in a story about banking in the wizarding world.
I think Luna Lovegood would make an excellent main character in a Harry Potter Ghost Hunters fanfic. She already has a very open - minded view of the magical world and is quite in tune with the more ethereal aspects of it. Fred and George Weasley could also be main characters. Their mischievous nature would lead them to be interested in ghost hunting, and they could use their inventions to help in their investigations. Additionally, Ginny Weasley could be part of the group, being brave and having her own experiences with the supernatural at Hogwarts.
Well, clearly Vionery is one of the main characters. Depending on the story, Harry Potter himself might also be a central figure, as he often is in most Hogwarts - related fanfictions. Hermione Granger could also be involved, using her intelligence to assist Vionery in her adventures or studies at Hogwarts.
In harry potter the marauders fanfiction, the main characters are the Marauders themselves. James Potter, the confident and sometimes arrogant Gryffindor. Sirius Black, the black sheep of his pure - blood family. Remus Lupin, the kind - hearted werewolf. And Peter Pettigrew, who was initially part of their tight - knit group. Their interactions, friendships, and later the events that lead to their fates are central to these fanfictions. They are often depicted in their Hogwarts days, full of youth, adventure, and magic.
Harry Potter is the mainstay, as the story is based in the Harry Potter universe. Kurama is the new element that makes it a crossover. In addition, characters like Snape could play significant roles. Snape's complex nature might lead to interesting interactions with Kurama. He could be initially hostile but then come to realize Kurama's value in the fight against the dark side. And of course, Hagrid, with his love for magical creatures, might befriend Kurama and help him adjust to the wizarding world.
Hermione Granger might also be a main character. She is an important part of the original series and her intelligence and knowledge would be useful in uncovering any truths in this fanfiction. Also, Ron Weasley could be there as Harry's loyal friend, and together they could face the challenges related to the 'truth' in the story.
Most likely Harry Potter himself would be one of the main characters. After all, it's in the title related to the Harry Potter world. And of course, the ogre would be a main character too as it's a key part of the fanfiction.
Harry Potter and his friends might also be main characters. Since it's a Harry Potter fanfiction, they could be involved in the story trying to figure out the mystery of the pretender. Hermione would probably be using her intelligence to analyze the situation, while Ron would be there for support and some comic relief.
