One possible storyline could be that fem Harry has some sort of special power or ability that makes Dumbledore take her under his wing as a 'pet' in a sense of protection and mentorship. Maybe she has a unique connection to magic that he wants to nurture.
I'm not sure of specific fanfictions with this exact plot. However, you can try searching on popular fanfiction websites like Fanfiction.net or Archive of Our Own. Use the search terms 'fem Harry' and 'Dumbledore's pet' to narrow down your results.
In some fanfictions, Harry might be depicted as Dumbledore's pet in a metaphorical sense. It could be that Dumbledore is overly protective or manipulative in the story, making Harry seem like a 'pet' under his control. But this is not a common or canonical view, just a creative interpretation in certain fan - created works.
Well, it depends on the fanfiction. Some fanfic authors like to play with the idea for the sake of creating an interesting twist. They might make Dumbledore seem overly possessive or controlling of Harry in this 'pet - like' way. But other fanfictions stay truer to the original idea of Dumbledore as a mentor, and in those, Harry is not really a 'pet' at all.
One implication could be a change in Harry's agency. If he's seen as a pet, he might seem less in control of his own actions and more like a tool for Dumbledore's plans. Another is that it could alter the way other characters view Harry. They might see him as less of an independent hero and more of Dumbledore's follower.
One reason could be to explore power imbalances. By making Harry seem like Dumbledore's pet, it shows how much power Dumbledore has over Harry's life and decisions. Another reason might be for a unique storytelling angle. It can create drama and tension, especially if Harry starts to rebel against this 'pet - like' status.
One common theme could be the exploration of an unconventional relationship. It might focus on the power dynamics between Hermione and fem Harry in this 'pet - like' relationship.
Dumbledore, as Harry's guardian in the fanfiction, would probably use his influence in the wizarding world. He could make sure that Harry is taught by the best teachers at Hogwarts. He'd also be there to offer advice and guidance, especially when Harry faces challenges like dealing with Voldemort or other dark forces. For example, he might teach Harry some advanced defensive magic privately to better protect himself.
A 'hermione is dumbledore's pet' fanfiction could have a lot of different interpretations. Maybe Dumbledore sees Hermione's intelligence as a valuable asset and decides to 'adopt' her in a sense. He could give her special tasks or privileges, like a pet owner would with their pet. On the other hand, Hermione might feel a bit restricted by this relationship at times, but also understand that Dumbledore has her best interests at heart. The fanfiction could also explore how the other characters in the Harry Potter world react to this strange relationship between them.
