Obviously, Crookshanks is a main character as it is the Potter's cat in this fanfiction. The Potter family members would also be main characters. Harry Potter himself would likely be important as he is the central figure in the Potter family. His friends might also make appearances as they often visit the Potter home, and their interactions with Crookshanks could be part of the story.
Crookshanks has a very special relationship with Hermione. In fanfiction, it's often shown as a deep bond of loyalty. Hermione trusts Crookshanks completely, and he, in turn, is always by her side, protecting her in his own cat - like ways. For instance, he might hiss at any potential danger that approaches Hermione.
Well, it could be that Crookshanks, as the Potter's cat, has a special bond with the Potter family members. It might have some unique magical abilities that are explored in the fanfiction. For example, it could be able to communicate with the Potters in a special way, or perhaps it has a connection to the magical defenses of the Potter household that we don't know about 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.
Well, obviously Cool Cat is a main character. He is usually the center of the action, with his cool and laid - back attitude.
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.
Crookshanks in the 'Harry and Crookshanks' lemon fanfiction could be important for several reasons. First, it might be used to add a touch of the familiar from the original Harry Potter series into this fan - created world. Second, it could play a role in the emotional development of the story. For instance, if Harry has a strong bond with Crookshanks, it can affect how he behaves in the 'lemon' parts of the fanfiction. Also, Crookshanks might be a source of humor or light - heartedness in a story that could potentially have some more intense or adult - like themes. This can create a balance and make the fanfiction more engaging.
It could also be a new character introduced in the fanfiction. This character might be someone with a special charm, perhaps a very intelligent and kind wizard who Crookshanks senses has a lot in common with Hermione. For example, he could be a wizard who is also very interested in books and knowledge, just like Hermione, and Crookshanks decides he is the perfect match for her.
Well, obviously Izuku is one of the main characters, even when he's turned into a cat. His friends like Bakugo and Ochaco are also likely to be main characters. They would be the ones trying to figure out what happened to Izuku and how to turn him back. And maybe All Might could also be a main character, if he gets involved in the whole situation to help his young protege.
