One great Tom and Hermione as siblings fanfiction is 'The Unlikely Bond'. It beautifully explores their relationship as siblings in the wizarding world. It shows how they support each other through different challenges at Hogwarts, like dealing with difficult classes and mean classmates.
It's interesting because it combines two very different characters. Hermione is known for her studiousness and loyalty to her friends, while Blaise has that Slytherin mystery. Merging them as siblings gives a whole new dynamic to explore.
One great Hermione Potter siblings fanfiction is 'The Potter Siblings' Bond'. It delves into the relationship between Hermione and her newfound Potter siblings. The story has a great plot with lots of character development.
I really liked 'Sibling Rivalry in the Wizarding World'. In this fanfic, Hermione and Draco as siblings have some intense moments. Their different personalities lead to some great plotlines. For example, Hermione's studious nature clashes with Draco's more laid - back and sometimes snobbish attitude, but at the end of the day, they still have that sibling bond that holds them together.
Another theme is the idea of family loyalty. Despite their differences, they are siblings. So, they often have to defend each other against others at Hogwarts. In some fanfictions, they might be in a situation where Draco is being bullied by other Slytherins for having a Muggle - born sister, and he has to decide whether to side with his house or his sister. And Hermione might have to deal with her Gryffindor friends not understanding why she's related to a Malfoy.
I really like 'Darker Ties'. In this fanfiction, the idea of Harry and Hermione being siblings is explored in a very unique way. There are a lot of plot twists. For example, their family history is intertwined with some dark secrets of the wizarding world. It's a page - turner as you keep wondering how their relationship as siblings will evolve in the face of all these revelations.
Lucius has a sense of entitlement that comes from his pure - blood upbringing and family wealth. Hermione, being a Muggle - born (in the original story), has had to fight for her place in the wizarding world. So in fanfiction as siblings, Lucius might initially look down on Hermione's more inclusive views, while Hermione would be appalled by Lucius's prejudice. However, as the story progresses, they could learn from each other. Lucius could become more open - minded and Hermione could understand the pressures of a pure - blood family.
If Hermione and Draco were siblings, their family would have to navigate two very different worlds. On one hand, they would have the elitist and often dark - tinged Slytherin world that Draco is a part of. On the other, there's Hermione's world of academic achievement and a more inclusive view of the wizarding community. Their parents would have to balance teaching them magic in different ways. Draco would probably be taught more about the pure - blood supremacy ideas initially, while Hermione would be encouraged to explore all aspects of magic regardless of blood status. It would be a family full of contradictions and debates.
One popular story might be 'The Zabini - Granger Bond'. It delves into how Blaise and Hermione, as siblings, navigate the wizarding world together. Their different personalities, with Blaise's Slytherin cunning and Hermione's Gryffindor bravery, create interesting interactions.
In some fanfics, their sibling bond leads to them developing new magical abilities together. For example, they might discover a combined spellcasting technique that no one else can do.
