I would not recommend looking for it. Since 'mudblood' is a derogatory term from Harry Potter, any fanfiction associated with it in such a way might involve offensive content.
One popular 'Hermione Mudblood' fanfic could be 'Hermione's Redemption'. It often delves into how Hermione overcomes the discrimination associated with the 'Mudblood' slur. It shows her growing in strength and character, facing challenges in the wizarding world with grace.
It depends on the type of fanfiction. In some darker, more edgy fanfictions that explore the extreme aspects of the Harry Potter universe, it might be more common as it delves into the power dynamics and prejudices. However, in more light - hearted or canon - compliant fanfictions, it would be less common as it goes against the general spirit of the original series which promotes equality.
Yes, there might be some fanfictions out there that explore darker or more complex storylines where such a thing could happen. However, this goes against the positive growth of their relationship in the original 'Harry Potter' series. In the canon, Ron's use of that term was a regrettable moment of weakness, and most fanfictions tend to uphold the characters' better natures.
In the Harry Potter universe, the term'mudblood' is a very discriminatory term for muggle - born wizards. Hermione, being a muggle - born, is an easy target in fanfics. Some writers use this to create conflict and show the prejudice that exists in the wizarding world.
Some fanfictions focus on the Mudblood character's relationship with Harry Potter himself. They might become close friends or allies, and together they fight against the discriminatory views in the wizarding society. This could involve them going on adventures, solving the mystery of their connection, and ultimately changing the way the wizarding world views blood purity.
In some fanfictions, Bellatrix screams 'Mudblood' at Hermione as a display of her pure - blood supremacist beliefs. Bellatrix, being a Death Eater, holds deep - seated prejudices against those with non - pure - blood heritage like Hermione. It's a way to demean and intimidate her.
Prejudice is a very common theme. Since Mudbloods are looked down upon in the wizarding world, many fanfictions focus on how they face and overcome this discrimination. For example, in some stories, Mudbloods have to prove themselves worthy in a world that doubts their abilities.
The term 'filthy little mudblood fanfiction' is quite concerning. Given that 'mudblood' is a discriminatory term in the Harry Potter series. Fanfiction often takes the elements of the original work and twists them. This could potentially be a fanfiction that uses this offensive term to create a story that might involve characters being mistreated or discriminated against in a fictional scenario. It might also be a work that tries to subvert or comment on the use of such a term in the original series, but again, without more details, it's difficult to determine precisely.
One common theme is the struggle against prejudice. In these fanfictions, the Death Eater often has to overcome their ingrained beliefs about Mudbloods, and the Mudblood has to face the danger from the Death Eater's side. Another theme is redemption. The Death Eater may seek to redeem themselves through their relationship with the Mudblood.
