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 Hermione is sent to the 'Vampire Diaries' world to retrieve a powerful magical artifact that has somehow ended up there. Along the way, she meets Damon and Stefan. She forms an unlikely friendship with them as they help her search for the artifact. In return, she uses her magic to protect them from some of the more dangerous supernatural threats in their world.
One idea could be that Hermione, with her vast knowledge from the wizarding world of Harry Potter, travels through time or a magical portal and meets Merlin. She could help Merlin with some of his more complex magical problems using her unique spells and techniques from Hogwarts. Another plot could involve them teaming up to defeat a common enemy that threatens both their worlds, perhaps a dark magic user who has found a way to bridge the two universes.
One idea could be Hermione using her magical knowledge in the world of a hitwoman. For example, she could use spells to enhance her stealth or disarm opponents in a non - magical way that would seem like the skills of a hitwoman. Another plot could involve Hermione having to take on the role of a hitwoman to protect the wizarding world from a dark force that is using the muggle underworld to its advantage. She would have to adapt to the hitwoman's code while still maintaining her own moral compass from the wizarding world.
One idea could be that they discover their relation during a magical crisis. Maybe a dark force is threatening both the wizarding world and the demigod world, and their combined powers as siblings help save the day. For example, Hermione's magic and knowledge of spells combined with Percy's control over water and his demigod strength.
Well, in some fanfiction, the plot might involve the wolf being a part of a prophecy related to Hermione. For example, it could be foretold that only she can save the wolf from an impending doom, like a dark magic that is slowly consuming it. This would lead her on a journey to find a cure or counter - spell. Also, the wolf could be a link to Hermione's past that she was unaware of. Maybe it was somehow connected to her family's hidden magical heritage, and as she gets to know the wolf, she uncovers long - lost family secrets.
A plot could revolve around Hermione's friends' reactions. For instance, Harry and Ron might be shocked at first but then become super protective. It could also show how Hermione's pregnancy affects her studies or her work in the wizarding world, perhaps she has to take a break from her research and how she copes with that.
A possible plot for Hermione and Dolohov fanfiction could be that Hermione is researching a very rare and dangerous form of magic. Dolohov, who has some knowledge about it, crosses her path. At first, they are at odds, but as they dig deeper into the mystery of this magic, they find that they need each other's skills. Maybe there is a prophecy involved that links their fates. This could lead to a series of adventures where they have to trust each other, even though their backgrounds are so different. It could also explore how Hermione's values might influence Dolohov or vice versa.
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.
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.
