I'm not sure if there is such a specific fanfiction. However, in the original 'Harry Potter' canon, Dumbledore would never do such a thing. Fanfictions sometimes take wild and unorthodox turns, but this would be a very dark and out - of - character concept. It might be a very rare and edgy take in some extreme fan - created stories.
If such a fanfiction exists, perhaps the motive could be a misdirected attempt at protecting the greater good. Maybe Dumbledore thought Hermione's parents were in some way a threat to the wizarding world's secrets that he was trying so hard to protect. But this is still a very far - fetched idea as Dumbledore was always about protecting life in the official story.
It could be a revenge plot gone too far. Suppose her parents did something in the past that she just found out about, and in her new dark persona, she decides to take the ultimate revenge. Or perhaps she has fallen so deep into the dark side that she no longer values family and sees them as just another obstacle in her path of darkness.
In this kind of fanfiction, it might be a way to shock the readers. Hermione is a beloved character, and her death at the hands of Bellatrix would be a very unexpected and tragic event. It could also be used to create a new plotline where her friends, like Harry and Ron, have to deal with her loss and seek revenge.
I haven't come across many (if any) fanfictions with this exact plot. It's a rather extreme idea. In the world of fanfiction, most writers like to keep the essence of the characters intact. But for those who do write about it, they might be exploring the darkest corners of the human (or in this case, wizard) psyche. They could be showing how power, or a wrong turn in life, can lead a character like Hermione, who is known for her goodness, to commit such an unthinkable act.
Yes, there are likely fanfictions out there with this dark and alternative take. Fanfiction often explores non - canonical ideas, and this would be a very radical one. It goes against the established lore in the official 'Harry Potter' series, but that's the nature of fanfiction - to play with different concepts.
In fanfiction, Draco and Hermione as parents might raise their children with a blend of values. Draco could teach them about the wizarding world's traditions and Hermione would instill in them the importance of equality and knowledge. Their parenting style might be strict yet loving. For example, they would ensure their children study hard but also encourage them to have fun and explore their magical abilities. Their family could be a unique mix of Slytherin cunning and Gryffindor courage.
Hermione's parents in fanfiction can be portrayed in various ways. Some fanfiction authors might give them more magical abilities or knowledge than they actually have in the original story. This could be to create more interesting plotlines. For instance, they could have a long - lost relative who was a powerful wizard and this connection is explored in the fanfic, which in turn affects Hermione's journey in the magical world.
One interesting aspect of Hermione Granger and her parents in fanfiction could be exploring how their Muggle background affects Hermione's Hogwarts experience. In some fanfictions, her parents might be more involved in the wizarding world than in the original series, which adds a new dimension to Hermione's story.
She would be devastated. Hermione is a very emotional person deep down. She might isolate herself at first, not wanting to talk to anyone, even her closest friends like Harry and Ron. She'll probably go through a phase of denial, not believing that her parents are really gone.
