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.
The main characters could be a group of Hufflepuff students. Hufflepuffs are often overlooked in the main Harry Potter story, but they are known for their loyalty and hard work. They could band together to form a ghost - hunting group. Their determination to solve the mystery of the ghosts in Hogwarts could drive the story. Maybe they are joined by a ghost of a former Hufflepuff student who guides them. Another possibility is that Professor McGonagall could be one of the main characters in a way. She could be the one who assigns or oversees the ghost hunt, and her wisdom and magical expertise would play an important role in the story.
I don't know the exact fanfic, but it could be Harry, Hermione, and Ron as they are often central characters in Harry Potter - related stories. They might be leading 'the hunt' for whatever the objective is in the fanfic.
It's also possible that some of the Death Eaters themselves could be main characters in a sense. For example, Bellatrix Lestrange could be a central figure if the fanfiction focuses on the power struggle within the Death Eater ranks during Harry's hunt, or if there is some backstory or different take on her relationship with Voldemort and the other Death Eaters.
In 'harry potter and ghost hunt fanfiction', a great crossover could be the sharing of knowledge between the two universes. The Ghost Hunt characters might learn about the different types of magic that exist in the Harry Potter world, like Divination which could be used to predict the actions of ghosts. On the other hand, the Harry Potter characters could gain insights from the Ghost Hunt team's scientific - like approach to understanding the supernatural, which could help them in dealing with the more dangerous magical creatures in their world.
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.
A possible plot for a Harry Potter Ghost Hunt fanfiction is that a group of students start seeing strange apparitions that seem to be leading them to a hidden chamber in Hogwarts. As they follow these ghostly figures, they realize that it's a test set by one of the founders of Hogwarts. If they succeed in the hunt and reach the chamber, they will be rewarded with a powerful magical artifact. Maybe it could be a wand that has the ability to control certain types of magic better than any other wand. Or perhaps a cloak that not only makes the wearer invisible but also provides protection from dark magic spells.
A really interesting combination would be Sirius Black and Naru from Ghost Hunt. Sirius has his wild side and his knowledge of the dark arts and the wizarding world. Naru is very mysterious and has great skills in ghost hunting. They could either be at odds or work really well together, depending on the situation. Their combined knowledge and personalities would make for a very engaging story.
The main characters are obviously Harry and Daphne. Harry, being the Boy Who Lived, has a lot of experience with fighting Voldemort and is determined to destroy all the Horcruxes. Daphne, on the other hand, is likely a Slytherin or has some connection to Slytherin. She brings her own set of skills and knowledge to the Horcrux hunt. Maybe she has a good understanding of dark magic or some family secrets that can be useful.
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.
There is probably a lead investigator. He or she is likely very knowledgeable about the paranormal.
In a 'ghost hunt story', the main characters usually are those who are drawn to the mystery of the supernatural. There are the ghost hunters, who are experienced in dealing with the unknown. They bring their knowledge and tools to the table. Then there are the witnesses, like the people who live near the haunted place or have had strange experiences there. Sometimes, there's also a psychic or medium who claims to be able to communicate with the spirits. These different types of characters interact and their experiences and beliefs collide, which makes for an interesting 'ghost hunt story'.
