A common plot is her rescue mission, as I mentioned before. Another is her psychological struggle while being held captive. She may have to endure torture or mind - games from the Death Eaters.
She might be used as a hostage to bargain with Harry Potter and his friends. The Death Eaters could try to extract information from her about the Order of the Phoenix.
Another theme is power struggle. Hermione, with her knowledge and magic skills, often has to face the power - hungry Death Eaters. It creates a lot of tension in the stories.
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.
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.
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.
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.
She could face legal issues in the wizarding world. Killing is not taken lightly, even if it's Death Eaters she's killing. There might be a trial to determine if her actions were justified. If the wizarding authorities are corrupt or influenced by the wrong people, she could even be wrongly convicted.
One possible storyline could be a complex exploration of redemption. Maybe a Death Eater has a change of heart after getting close to Hermione, and they both try to work against the dark side from within the Death Eater ranks. It could be full of intrigue as they keep their new alliance a secret.
One possible plotline could be a story of redemption. Maybe a Death Eater starts to question their beliefs after getting to know Hermione on a deeper level. For example, they could be forced to work together on a mission and gradually see the good in her, leading to a change in their ways.
Often, there's a plot point about Hermione being in a position where she is a target of the Death Eaters' sick plans. She may have to face their attempts at brainwashing or coercing her into their 'breeding' scheme. There could also be a plot point where her friends, like Harry and Ron, try to rescue her from this dark situation. But it's important to remember that these fanfictions can be quite disturbing and far from the original story's essence.
