Hermione could be more empathetic and help Harry adjust to the physical and social changes.
Well, perhaps in the fanfiction, Harry's dragon form is initially out of control. He has to learn how to master it with the help of his friends, like Hermione researching ancient spells to help him gain control. Or maybe there's a prophecy related to his dragon - turning ability that makes him a target for both good and bad wizards. The story could also focus on how Harry uses his dragon form to participate in a magical tournament that usually doesn't allow such unique abilities.

One idea could be that the Dursleys' constant mistreatment and abuse over the years gradually chip away at Harry's sense of right and wrong, making him more susceptible to dark influences. Another might be that they introduce him to dark wizards or artifacts that start to sway his view of magic towards the darker side.
One idea could be that Harry's new appearance as a girl causes a stir at Hogwarts. His friends are initially shocked but then accept him as always.

Maybe he even gets to experience the wizarding world from a different perspective as a girl, like how people interact with him differently in social situations.
One idea could be that as a girl, Harry has a different approach to dealing with the challenges at Hogwarts. For example, she might use her charm more subtly to influence others and gain allies. Another could be that her relationships with male characters like Ron and Hermione develop in new and unexpected ways, perhaps with a more sisterly bond with Ron and a different kind of friendship with Hermione.
A plot could involve Harry's exploration of her new identity within the wizarding world's gender norms. She could discover new magical abilities or sensitivities that are related to her transition. For instance, she might find that she has a stronger connection to certain types of magic that are more associated with femininity in the wizarding lore. Additionally, Harry could form a group of like - minded witches who are also challenging the traditional gender roles in Hogwarts, and together they could work on projects or causes that promote gender equality in the magical community.
One idea could be that as a girl, Harry has different social interactions at Hogwarts. For example, she might form closer friendships with female characters earlier. Maybe she would be more empathetic in certain situations compared to the male Harry in the original story.
One idea could be that Harry discovers a magical spell that gradually changes his physical form to that of a girl. He then has to deal with the reactions of his friends like Ron and Hermione. Ron might be initially confused but eventually supportive, while Hermione could be more analytical about the magic involved and how it might affect Harry's future at Hogwarts.
One idea could be a quest where the main character has to rescue a monster girl who has unique magical abilities that are crucial to the wizarding world.

Well, the girl could be a very talented young witch who is a bit of an outcast among her peers because she's so young but so powerful. Harry notices her and they start to practice magic together in secret. They could form a special bond over their shared love of magic and a desire to use it for good. Maybe they end up finding a hidden chamber in Hogwarts that contains ancient spells, and they have to work together to protect these spells from falling into the wrong hands.
