There could also be a plot where Rodolphus is sent on a mission to spy on Hermione, but instead, he becomes fascinated by her. This leads to a complex relationship where he has to balance his loyalty to the Death Eaters and his growing feelings for Hermione. It's a really interesting exploration of conflicting loyalties and unexpected love.
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 plot idea could be that in an alternate universe, Rodolphus, after realizing the error of his ways in the wizarding war, tries to make amends by protecting Hermione from a new dark threat. This could lead to a begrudging partnership that slowly turns into an unexpected friendship or more.
In some fanfictions, there could be a situation where Hermione forms an unexpected bond with Rodolphus. Maybe she starts to understand his backstory and what led him to become a Death Eater. This could lead to a complex relationship where she tries to redeem him in a way. Or perhaps, Rodolphus discovers that Hermione is far more powerful and resourceful than he initially thought, and this throws his plans into chaos as he has to constantly adapt to her actions.
One common plot is revenge against those who bullied her at Hogwarts. Maybe some Slytherins were mean to her, and she uses her intelligence and magic to get back at them in creative ways.
One plot idea could be that Hermione and Rodolphus travel back to the time when the Hogwarts founders were alive. Hermione could use her knowledge to try and influence the early magical laws and education system. Meanwhile, Rodolphus, being from a different era, would have a hard time adjusting and his dark magic - influenced mindset might create conflicts. For example, he might try to introduce some of the more extreme pure - blood ideologies which Hermione would vehemently oppose.
One good one might be 'Rodolphus' Redemption' where Rodolphus starts to question his Death Eater ways after meeting Hermione. It shows a different side of him and how their interactions could lead to a change in the wizarding world's power dynamics.
One popular plot is the redemption arc of Severus Snape through his relationship with Hermione. In these stories, Hermione might see a side of Snape that others don't and help him come to terms with his past actions.
Well, in some cases, the plot might involve Hermione using her extraordinary intelligence in new and unexpected ways. For example, she could be inventing new spells far beyond what is taught at Hogwarts. Maybe she discovers a hidden aspect of magic that even the most learned wizards don't know about. This could lead to her having to face challenges from those who are threatened by her newfound knowledge.
Well, one possible interesting plot could be Hermione using her intelligence in a mercenary role to outwit her opponents. For example, she might use her knowledge of magic to create unique battle strategies.
One possible plot could be Hermione using her intelligence to find a way to repel Dementors without using a Patronus. Maybe she discovers some ancient magic or potion that can keep Dementors at bay. Another plot could involve a Dementor being somehow controlled by a dark wizard to specifically target Hermione, and she has to outwit both the Dementor and the wizard. There could also be a story where Hermione befriends a Dementor in a very strange turn of events, perhaps by understanding its true nature and finding a way to communicate with it, which would be a very unique take on the relationship between a character and a Dementor in fanfiction.
