The main characters would probably start with the obvious ones from the Harry Potter series, Harry, Hermione, and Ron. But the cat spirit would be a key character too. There might also be other magical creatures or characters that are more closely associated with the cat spirit. For example, the caretaker Filch might have a particular reaction to the cat spirit, either being annoyed by it or having some sort of past connection that gets revealed. And then there could be other students who the cat spirit befriends or helps out, which would make them important in the story as well.
Since it's a fanfic with a cat spirit, there might be a new character who is the cat spirit. This character could be as important as the main trio. And there could also be some other characters from the original series who have special interactions with the cat spirit, like Professor Dumbledore. He might be interested in the cat spirit's powers and try to understand how it fits into the magical world of Hogwarts. Also, characters like Draco Malfoy could be involved, perhaps having some sort of rivalry or unexpected alliance with the cat spirit or those associated with it.
Without reading the fanfic, it's hard to say for sure. But it could be Harry Potter himself given a scaredy - cat personality twist for the purposes of this fan - made story. Or it could be a new character created by the fanfic author who is the central scaredy - cat figure.
It's hard to say for sure without reading it, but it could be Harry Potter himself. Since it's still within the Harry Potter universe, he might be the one to interact with the Spirit of Fire. Maybe Hermione could also be a main character, using her intelligence to figure out the secrets of the Spirit of Fire. Ron could be there too, providing his loyalty and friendship.
One interesting aspect could be how the cat spirit is integrated into the existing Harry Potter universe. Maybe it has unique magical abilities that interact with the known spells and magic in the series.
Well, Harry Potter is surely one of the main characters since it's in the title. And I would assume his friends like Ron Weasley and Hermione Granger would also be main characters as they are important in his life in the original series.
Well, often the cat - girl herself is a main character. She could be an original character created by the fanfiction writer, with her own backstory, personality, and goals within the Harry Potter universe.
Well, the pet cat girl herself is often a main character. She could be named something unique like Lyra. And then there might be some of the original Harry Potter characters like Harry, Hermione, and Ron. They could interact with the cat girl, maybe at first being a bit suspicious but then growing to be friends.
It could be a Muggle - born protega. This character would face unique challenges as they try to protect the wizarding world while also dealing with their own identity issues. They might have friends among the Hogwarts students, and together they form a group to counter a new evil force that targets both Muggles and wizards.
Without reading it, it's hard to say. But it could feature the main characters from the original series like Harry, Hermione, and Ron as they are usually central in most Harry Potter fanfics. They might be the ones trying to solve the conundrum.
Since it's a fanfic, the main characters could be a mix of new and existing characters from the Harry Potter world. Maybe it has Harry, Ron, and Hermione in some sort of mentoring role to the new hunters. Or it could be entirely new characters who are on a journey of their own, exploring parts of the wizarding world that haven't been fully explored in the original series, like some hidden areas where they need to hunt for something important.
Most likely, the main character is the healer. They could be an original character created for the fanfic. There might also be appearances from well - known Harry Potter characters like Harry himself, Hermione, and Ron. Maybe the healer has to work with them to solve some sort of magical health crisis in Hogwarts or the wizarding world at large.
