Neville could also be an unexpected coach. He has a deep knowledge of plants and could use that to create special potions or herbal remedies to help Hermione with things like muscle recovery or enhancing her flexibility. His kind and patient nature would make him a great coach for Hermione.
McGonagall could be her coach. McGonagall is strict and has high standards, which would push Hermione to be the best she could be in gymnastics. She could use her Transfiguration skills to create unique training equipment for Hermione.
One idea could be that Hermione uses her intelligence to create new gymnastic moves. For example, she might study the laws of physics and motion to develop unique flips or spins that no one has ever seen before. This would not only show her as a talented gymnast but also highlight her intellectual side.
There's a fanfic titled 'Gymnast Hermione'. In this, Hermione discovers her love for gymnastics during a school trip. It has detailed descriptions of her training and how she overcomes challenges both in the muggle gymnastics world and her magical studies. It's really interesting as it gives a new dimension to Hermione's character.
The unique part about Hermione gymnastics fanfiction is that it combines two very different worlds - the magical world of Harry Potter and the athletic world of gymnastics. It allows for creative interpretations of Hermione's character, like seeing her discipline in magic translate to her gymnastic training.
The plot could be that Harry, feeling stressed from all the dark magic and Voldemort threats, stumbles upon a Muggle gymnastics event. He becomes fascinated and decides to secretly learn gymnastics. He practices in hidden corners of Hogwarts, using his magic to help him with balance and strength. Eventually, his friends find out and they support him, and he even enters a wizard - Muggle combined gymnastics competition.
Well, Ron and Harry would most likely be main characters. They're Hermione's best friends, so they'd be right there by her side when she breaks her leg. They'd probably be the ones helping her get to the hospital wing, getting her books for her when she can't walk to the library, and generally just being there for her.
Yes, there are quite a few. You can start by looking on fanfiction websites like Archive of Our Own. There, you might find various stories about Bella doing gymnastics that range from her training experiences to competing in big events.
Hermione might become a reclusive healer. Changing her identity to that of a healer who lives in a hidden cottage in the woods. She would keep her identity a secret and only help those who stumble upon her cottage. This new identity would give her the chance to focus on her study of magical healing in peace, away from the chaos of the wizarding world she knew before.
Voldemort's remaining followers could be her enemies. They might be planning something new and Hermione, as a spy, would be trying to stop them. Also, some corrupt Ministry of Magic officials who are up to no good. They would see Hermione as a threat to their secret operations.
Neville could be an ally too. His skills in herbology could come in handy when it comes to finding the right plants to feed the dragons or to use for medicinal purposes. Also, Luna Lovegood might be involved. Her unique perspective and knowledge of strange magical creatures could give Hermione new ideas on how to care for the dragons. She might know of some obscure spells or methods that are beneficial.
There could be many amateur fanfiction writers out there who might have come up with this idea. It could be someone who really loves Hermione's character and wanted to explore a more supernatural side of the Harry Potter universe with her in it.
