One interesting fanfiction could be about the Dursleys having a change of heart before Harry goes to Hogwarts. Maybe they start to see the magic in him in a different way and struggle with their newfound feelings of protectiveness. It could show a different side of the usually cruel Dursleys.
There might be a fanfiction where the Dursleys are forced to enter the wizarding world because of some magical mishap related to Harry. This would be quite a comical situation as they are so against magic. They'd be out of their depth, dealing with wizards and witches while still trying to hold on to their Muggle ways.
A great fanfiction idea could be that the Dursleys receive a letter from Hogwarts themselves, thinking it's a prank at first. But as they start to investigate, they discover some long - lost family connection to the wizarding world. This could lead to a whole new adventure for them, with them having to face their prejudices against magic.
One popular fanfiction might be about the Dursleys' secret past that somehow ties them to the wizarding world in a more complex way. For example, perhaps there was a wizard in their family line long ago that they've been trying to hide. Another could be a story where the Dursleys have a change of heart much earlier than in the original series and start to embrace Harry's magical nature, leading to all sorts of comical and heartwarming situations as they try to understand the wizarding world. And there could be a fanfiction where the Dursleys are forced to face the consequences of their mistreatment of Harry in a more magical and extreme way, like being haunted by magical apparitions that represent Harry's pain.
There might be a fanfiction where the Dursleys are actually related to a minor wizarding family in some convoluted way. This discovery could lead to a whole new set of adventures and relationships for them. They could be dragged into a wizarding mystery that forces them to cooperate with Harry and other wizards, which would be a huge change from their usual behavior of trying to avoid all things magical.
Yes, there are. Some fanfictions focus on the Dursleys' hidden depths. For example, in certain stories, Petunia's jealousy of Lily is explored in a more complex way, showing how her upbringing and the magical world's intrusion into her normal life affected her actions towards Harry. These fanfictions often give the Dursleys more humanizing qualities, like Vernon's insecurities about his normalcy compared to the magical world, which is a fresh perspective compared to their rather one - dimensional portrayal in the original books.
One interesting fanfic could be where the Dursleys are secretly magical but have been suppressing it. Maybe in this fanfic, Vernon Dursley has a hidden ability to communicate with magical animals, which he has always feared and tried to hide. This would completely change the dynamic of how they treat Harry as they are also hiding their own secrets.
A great 'Harry Potter Dursleys fanfic' might explore the Dursleys' backstory more deeply. For example, it could show how Vernon's hatred for magic and strange things developed over time. Or it could focus on Petunia's envy of Lily's magical abilities and how that affected her relationship with Harry. Some fanfics also imagine a scenario where the Dursleys are magically transported to Hogwarts and have to adapt to the magical environment. They would be completely out of their element, and it would be interesting to see how they interact with the students and teachers.
One possible plotline could be Harry finding a magical way to fight back against the Dursleys' torture while still hiding his magic from the Muggle world. For example, he might use some subtle magic to make things go wrong for the Dursleys when they are being especially cruel. Another could be that his Hogwarts friends discover what's going on and come up with a plan to rescue him during the holidays. Maybe Hermione uses her knowledge of the law to find a way to legally remove Harry from the Dursleys' custody.
One idea could be exploring how the Dursleys react when Harry starts to show signs of magic before he even goes to Hogwarts. Maybe he accidentally makes Dudley float during a family dinner.
In some of these fanfics, one interesting plot could be Harry finding solace in an unexpected friendship with a local magical creature that the Dursleys were unaware of. This gives him a sense of purpose and connection outside of the neglect he faces at home.
In some 'Harry Potter and the Dursleys' fanfics, there's a plot twist where the Dursleys are actually protecting Harry from a greater threat that the wizarding world doesn't even know about. They've been cruel to keep him close and safe. Also, there could be a twist where Vernon Dursley has a connection to the wizarding world through his family's past that he's been trying to hide all along, which changes how we view his hatred for magic.
In certain fanfictions of this type, Harry could be found by a powerful but reclusive wizard. This wizard decides to mentor Harry in the ways of ancient and lost magics. Harry then uses this knowledge to not only become a very powerful wizard but also to change the wizarding world's view on things like blood purity. He may also go on a journey to find out why the Dursleys abandoned him and in the process, uncover some dark secrets about his family that had been long buried.
