Perhaps she teaches the past about the importance of unity among different magical communities. In the fanfiction, she could be involved in bringing together different magical groups like house - elves, goblins and wizards to work towards a common good. This would change the course of magical history in that time period.
Another plot could be Hermione teaching past wizards about the long - term consequences of dark magic. She might show them how certain spells and practices can lead to the destruction of the magical world in the future. By doing so, she could potentially prevent some of the dark events that are part of the wizarding history we know.
One interesting plot could be Hermione using her advanced knowledge to correct historical misunderstandings in the past. For example, she might teach the wizards of the past about Muggle - friendly magic that they were previously unaware of.
One interesting plot could be Hermione using her advanced knowledge to teach the Marauders about complex magic they hadn't considered before. Maybe she teaches them about time - turning spells in a more in - depth way, leading to some unexpected adventures where they have to use this knowledge carefully.
One interesting plot could be that Snape, while teaching Harry, discovers a hidden talent in him for a very rare branch of magic. He then decides to secretly mentor Harry in that area, leading to a unique bond between them.

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.
A possible plot is that Hermione, as a succubus, discovers a connection between her new form and an ancient magic in the wizarding world. Harry and Hermione then team up to explore this connection and in the process, they uncover secrets about the origins of magic that were long forgotten.
