Hermione could also use her friendships as a source of strength. If she was in a situation with the Death Eaters, she would think about her friends in the Order of Phoenix, like Harry and Ron. This would give her the motivation to keep fighting and resisting, knowing that her actions could protect her friends and the wizarding world.
Hermione could resist the Death Eaters with her vast knowledge of magic. For example, she could use protective spells and charms she has learned from her studies. She might also use her quick thinking to outwit them in verbal exchanges, not giving them any information or advantage.
She could use her intelligence. Maybe she could pretend to cooperate while actually looking for loopholes in their plans or trying to send hidden signals to her friends. For example, she could subtly mislead them about the location of important items or people.
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.
Well, she could end up in a duel with a powerful Death Eater. Hermione is a very skilled witch, so it would be a great show of her magical abilities. Maybe she discovers a new spell during the fight that helps her gain the upper hand.
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.
One way it could develop is through the use of dark magic coercion. Maybe a powerful Death Eater discovers Hermione's intelligence and decides to use Imperius Curse to make her his slave. He could force her to use her magic skills for his evil purposes, like brewing dangerous potions or stealing valuable magical artifacts.
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.
In this fanfiction, Hermione could rehabilitate Death Eaters by showing them the error of their ways. She may expose them to the harm they've caused to both the Muggle - born and the wizarding community at large. By making them face the consequences of their actions on a personal level, like the families they've torn apart, she might start to change their views.
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.
One possible motivation could be that she's been tricked. Maybe a powerful Death Eater has cast a spell on her to make her believe their cause is just. Another could be that she's trying to protect her friends. She might think that by joining the Death Eaters, she can keep Harry and Ron out of danger.
Well, in this kind of fanfiction, perhaps Hermione is captured because she was on a solo mission to retrieve some important magical item. The Death Eaters could use her knowledge to try and break into the secrets of the Order of Phoenix. Meanwhile, Hermione could be using her wits to delay them and send out hidden signals for help.
