Another plot could be that Hermione, being the brilliant witch she is, gets sorted into Hufflepuff by mistake (or maybe it's not a mistake). She initially struggles with the idea as she has always identified more with Gryffindor. But as she spends time in Hufflepuff, she realizes that the house values are just as important and noble. She then uses her intelligence to help Hufflepuff gain more recognition in the wizarding community.
Maybe the Hufflepuff male OC is an exceptional flyer, even though Hufflepuff isn't known for Quidditch. He tries out for the team and faces discrimination from some of the other houses at first. But through his hard work and kind nature, he not only makes the team but also helps to bring unity among the different houses in the Quidditch matches.
One idea could be that Hermione discovers she has a special connection to the gorgon world. Maybe she can understand their language and has to use this ability to prevent a war between the gorgons and the wizarding world. Another plot could involve Hermione being turned into a gorgon - like creature temporarily and having to learn to control her new powers while facing prejudice from some of her classmates.
A possible plot could be that Hermione gets bitten by Greyback accidentally. Instead of turning into a full - blown werewolf, she has some new abilities and a strange connection to Greyback. They then have to figure out how to deal with this new situation, while also facing the wizarding world's prejudice against werewolves. It could also involve Hermione using her intelligence to find a cure for herself and in the process, changing Greyback's view of non - werewolves.
A possible plot is that Hermione, while researching for a new spell theory, stumbles upon a long - forgotten charm that was created by Rodolphus. This draws her attention to him, and she decides to find out more. Meanwhile, Rodolphus, who has been in hiding, senses someone is looking into his past work. When they meet, there is a clash of personalities. However, as they start to discuss the charm and its potential, they find common ground. Another idea is that in a world where magic is fading, Hermione believes that Rodolphus might have some knowledge that could help. She approaches him despite the risks. He, in turn, sees an opportunity to make amends for his past deeds through helping her. Also, they could be brought together by a prophecy that only they can fulfill, which forces them to put aside their differences and work together.
One interesting plot idea could be that Krum returns to Hogwarts for a Quidditch tournament. Hermione is now a teacher's assistant, and they rekindle their old feelings while discussing the strategies of the game. They face some opposition from students who don't understand their relationship, but they work through it together.
A third plot idea is that Hermione, in a strange magical accident, gets some of Morgana's memories. She then has to deal with these new memories and the emotions that come with them. She might struggle between her own values and the things she sees in Morgana's memories. This could lead to a transformation in Hermione's character as she tries to make sense of it all.
One plot idea could be that Hermione is a powerful elf with ancient magic knowledge. She uses her elven abilities to solve mysteries in Hogwarts that normal humans couldn't. Another could be that she's a magical being from a different dimension, and she has to hide her true form while trying to fit in at Hogwarts. Maybe she's a phoenix in human disguise, and she shows her phoenix powers at crucial moments to save her friends.
Some possible plot ideas include Hermione being mistaken for a powerful Grounder because of her magic. She could then use this to her advantage to broker peace between the different factions. Or maybe she discovers a magical element in The 100's world that she didn't expect, like a magical artifact left over from a pre - apocalyptic civilization. This could lead to a race among the different groups to obtain it, with Hermione in the middle trying to ensure it's used for good.
Well, perhaps in the 'hermione is a jedi fanfiction', there is a plot where Hermione goes on a quest across different galaxies as a Jedi. She meets various alien species and uses her knowledge of both Jedi and wizardry to solve problems. For example, she might use spells to repair a broken spaceship or use the Force to find a hidden magical artifact in an alien planet. And she could also have a showdown with a Sith - like character who is also a powerful dark wizard.
A plot where they are both transported to an alternate dimension and have to rely on each other's skills to survive. Hermione's intelligence and Clint's combat abilities would be put to the test as they figure out how to get back home.
