Well, it could make Hermione a lot more conflicted. Growing up with Death Eater parents, she might constantly struggle between the values she's exposed to at home and the ones she discovers at Hogwarts. For example, she might initially be more hesitant about befriending Harry and Ron due to her family's possible prejudice against 'blood traitors'. This could lead to a more complex and nuanced character arc as she gradually breaks away from her family's ideology.
Well, in some fanfictions, Hermione might use her superior intellect. She could outwit the Death Eaters by setting up elaborate magical traps. For example, she could use transfiguration magic to create objects that suddenly turn into something dangerous when the Death Eaters approach. Another way could be through her extensive knowledge of potions. She might create a potion that incapacitates or kills them when they come into contact with it.
A fanfiction involving Hermione and Death Eaters could focus on a moral dilemma. For example, if Hermione has the chance to save a Death Eater's life, would she do it? This could explore her character's sense of right and wrong. It could also be about how she endures the psychological torture that the Death Eaters might inflict on her, showing her strength and resilience.
Some of the pure - blood wizarding families who have been directly affected by the Death Eaters' actions would likely oppose Hermione. They have lost loved ones and may not be able to forgive. Also, there could be some Ministry of Magic officials who are more focused on punishment rather than rehabilitation and would stand against Hermione's efforts.
If Hermione joined the Death Eaters in fanfiction, it would completely turn the original plot on its head. The Death Eaters are known for their dark magic and prejudice, which is the opposite of Hermione's values. This could lead to a very different kind of story, perhaps one where she tries to change the Death Eaters from the inside, or she could be a double agent. It would be a very dark and complex alternate universe.
In some fanfictions, Hermione's adoption might make her more self - reflective. She may question her identity more often, leading to a deeper understanding of herself. For example, if she discovers she was adopted from a different magical culture, she might explore that culture and in turn, become more open - minded.
Well, her character would likely become more guarded. Snape is not one for open displays of affection or warmth, so Hermione might learn to hide her emotions more. However, she would also be exposed to Snape's vast knowledge of potions and the Dark Arts in a more intimate way. This could make her more of an enigma to her friends. She might start to question some of the Gryffindor values she once held dear, as Snape would surely instill in her a different set of beliefs, at least to some extent.
If Hermione was adopted by the Cullens, her character would likely become more attuned to the vampire world's values. She might be more secretive like the Cullens, as they hide their true nature. Her studious nature could be redirected towards understanding vampire lore. For example, instead of poring over Hogwarts textbooks, she'd be delving into books about vampire history and abilities. This new family dynamic would also make her more cautious in her interactions, knowing the potential danger her new family could face if exposed.
Hermione might become more protective. If her twin is in any sort of danger or facing difficulties, she would step up more. For instance, if the twin gets bullied for being different, Hermione would use her wits and knowledge to stand up for them.
Often, they portray her as brave and resourceful. Despite the danger of the Death Eaters, she is shown as someone who doesn't back down easily. For instance, she might use her vast knowledge of magic to hold her own against them.
One great fanfiction with Hermione and multiple Death Eaters could be 'The Dark Encounters'. In this story, Hermione finds herself in a situation where she has to outwit several Death Eaters at once. It shows her intelligence and bravery in the face of danger. Another one might be 'Hermione's Trials Among the Death Eaters' which delves into how she uses her magic skills in a unique way to deal with them.
