What are some interesting plotlines in Harry Potter and Hermione fanfiction that don't involve romantic relationships?

There might be a fanfiction where Percy and Rhea are on a mission to retrieve a powerful artifact that was stolen from a sacred place. They have to face many obstacles and enemies along the way, and their teamwork is crucial for success. This plotline is all about adventure and cooperation.

There could be a plot where Snape discovers that Remus has a unique talent for a particular branch of magic that he respects, like ancient runes. Snape then asks Remus to help him with a research project related to it. As they work together, they overcome their initial animosity. Also, a story could be set during a time of crisis at Hogwarts, like a magical plague that is affecting the students, and Snape and Remus must put aside their differences to find a cure.

One popular theme is the romantic relationships between the main characters like Harry and Ginny or Ron and Hermione. These relationships were hinted at in the original books and fans often like to explore them further in fanfiction. Another theme is the adventures of the characters after the events of the books, for example, how they continue to fight against the remnants of dark magic.

There's 'Soulbond of Friendship'. This fanfic explores a soulbond that is purely based on friendship. It features Harry and Ron and how their bond gives them an edge in Quidditch and in their adventures around the school. The story is light - hearted and fun.

One plotline could be Snape recognizing Hermione's exceptional academic abilities early on and secretly guiding her in her studies, especially in Potions. This could be a story of a mentor - mentee relationship where Slytherin is just the house Snape belongs to, not the center of any improper content. For example, Snape might leave her special instructions or books to help her excel.

One interesting concept is time - travel fanfictions. For example, a character might go back in time and change a small event that has a big impact on the future of the wizarding world. It's a great way to play with the established timeline of the 'Harry Potter' series.

A third idea could be a time - travel fanfiction. A character could go back in time to the era of the founders of Hogwarts. They could learn about the origins of the school, the sorting hat, and the different spells that were created back then. It would be a great way to explore the history of the 'Harry Potter' world without any adult elements.

In some 'Harry Potter turns into Hermione fanfiction', the plot may involve Harry adjusting to Hermione's physical appearance as well. He might be shocked at first but then realizes the advantages it gives him. For example, he could use Hermione's reputation for being a bookworm to his advantage when it comes to researching dark magic or hidden secrets in the library. And he may also face some difficulties when it comes to Hermione's friendships with other girls, as he has to act like her and keep those relationships intact.

One common plotline is Hermione's academic achievements post - Hogwarts. She could be researching new spells or making contributions to the wizarding academic world. Another is her relationship with her friends. Maybe she's planning a big reunion or helping a friend through a difficult time. Also, her love life can be explored in a positive way, like a romantic getaway with her partner or a sweet courtship story.

A plotline where Goku and Krillin get lost in an uncharted part of the universe and have to find their way back home. Along the way, they meet new alien species, learn new fighting styles, and of course, have each other's backs. It would be an adventure - filled story that focuses on their friendship and survival skills.
