Who are the main characters in 'harry is vernon's pet' fanfiction?

Obviously, Harry Vernon is a main character. But often, there are other characters created specifically for the fanfic or borrowed from the original source material if it's related to a known franchise. For example, if it's in a magical - themed fanfic, there could be a wise old wizard who guides Harry Vernon on his journey. Or a young sidekick who accompanies him in his adventures.

Petunia could be a great addition. Her relationship with both Harry and Vernon adds a lot of complexity. She could be the mediator or the one causing more trouble between them, depending on the plot.

One possible plot could be that Harry, through some magical mishap, is transformed into a small animal and Vernon, instead of being his usual cruel self, finds himself oddly attached to this new form of Harry. He might start to protect Harry from other threats in the wizarding world, not fully understanding what he's gotten into but feeling a sense of responsibility.

The main characters are Harry and Luna, but it's possible that some new characters are introduced in this fanfiction. Maybe there's a wizard who doesn't approve of a human having another wizard as a pet and tries to separate them. Or there could be a friendly character who helps Harry take care of Luna and teaches him special spells to enhance their bond.

Harry, even as a pet, would likely still have his brave and curious nature. He might be constantly trying to figure out a way to break the spell or understand the situation better. Draco would probably be his usual haughty self at first, but gradually show a more caring side as he gets used to having Harry as a pet.

Harry is surely the central character in 'harry trained as a pet fanfiction'. Besides him, it could be that his friends like Ron and Hermione are also involved, either trying to rescue him from this strange situation or being part of the process that led to his being trained as a pet. There might also be a new character, perhaps a dark wizard or a quirky magical creature, who is responsible for the training.

Perhaps there's a mentor figure, an old and experienced pet trainer who gives Harry advice from time to time. Another possible character could be Harry's rival in the pet training world. This rival might always be trying to outdo Harry in training different pets, which adds some drama to the story.

The main characters are obviously Ruby and Harry. Ruby is the young huntress from RWBY, and Harry, in this fanfiction, is her pet.

In some fanfictions, Harry might cope by finding solace in his friends at Hogwarts. He could talk to Hermione and Ron about what Vernon does, and their support gives him strength. For example, they might encourage him to focus on his magic studies as an escape from the Dursley's household.

Maybe Vernon is jealous of Harry's magical abilities. He might see Harry as a threat to his 'normal' family image. Also, Vernon has always been a bully at heart and Harry, being an easy target in his house, becomes the victim of his pent - up anger.
