Hermione and Percy could bond over their shared love for academic achievements. They might study ancient runes together, with Percy sharing his insights from his years at Hogwarts before Hermione arrived. Their friendship could also be tested when it comes to matters of school rules. Percy, being a stickler for rules, might initially be hesitant about some of Hermione's more adventurous ideas to break minor rules in the pursuit of knowledge. But in the end, they would come to respect each other's views and strengthen their friendship through mutual understanding.
Perhaps in the fanfiction, Percy discovers that Hermione has a rare magical ability that she's been hiding. He offers to help her master it without getting in trouble with the school authorities. As they work together on this, they form a strong bond. Their friendship could also involve them trying to solve a mystery within Hogwarts, like a series of strange disappearances of magical artifacts. They use their combined knowledge and skills to investigate, which not only brings them closer but also uncovers a plot that could endanger the whole school.
One great fanfiction could be 'Hermione and Percy's Hogwarts Adventures'. It delves into how their friendship might have developed outside of their normal friend groups. It shows Percy helping Hermione with her studies in a more detailed way than in the original books, and Hermione in turn helps Percy loosen up a bit.
Their friendship could also impact the political climate at Hogwarts. Percy is always very much into the rules and order side of things. With Hermione as his friend, they could form a sort of alliance between the students who are more studious and those who are in positions of power like Percy was in the Prefect role. This could lead to more student - led initiatives for change in the school, like better library resources or more interesting classes. Hermione could bring up the ideas and Percy could help push them through the proper channels.
One idea could be that Percy and Clarisse are forced to team up on a quest outside of Camp Half - Blood. At first, they bicker constantly like they used to, but as they face various challenges, they start to see each other's strengths. For example, Percy realizes Clarisse's battle skills are invaluable in a fight against a group of powerful monsters. They gradually become friends and learn to respect each other more than ever before.
Athena might also be a good candidate. Although she and Poseidon have their differences, she could see Percy's potential and befriend him. She could offer him wisdom and strategic advice for his various adventures.
In fanfiction, Hermione's Muggle friends are sometimes depicted as being very accepting of her magical life. They don't question it too much and are just happy to be part of her world in a way.
One possible fanfiction could be about Hermione and Ginny teaming up to solve a mystery at Hogwarts. Maybe they notice some strange behavior among the younger students and decide to investigate. Along the way, they rely on their different strengths - Hermione's vast knowledge and Ginny's Quidditch - inspired courage and quick thinking. Their friendship deepens as they face challenges together.
One great fanfiction about Hermione and Theo as best friends is 'The Unlikely Bond'. In this story, it starts with them being forced to work on a project together in Hogwarts. Theo's initially reserved nature and Hermione's studious attitude create an interesting dynamic. As they spend more time together, they discover shared interests beyond academics, like a love for magical creatures. Their friendship grows as they support each other through various challenges, such as Theo dealing with his family's expectations and Hermione facing the pressure of being the top student.
One interesting aspect in fanfiction about Hermione Granger's Muggle friends could be how they react to the wizarding world. Maybe they are initially shocked but then become fascinated by magic.
