Voldemort himself, of course, is the most prominent in a sense. But in the fanfiction, his relationship with the other Death Eaters could be different. He might be more distrustful or have different expectations of them. And then there's Barty Crouch Jr. He could be a major player in the fanfiction, with his skills in disguise and dark magic. His actions could drive some of the major plotlines in the fanfiction.
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.
Yes, there are some. However, the concept often involves dark and disturbing themes. Some fanfictions might explore how Hermione could be affected by the dark forces associated with Death Eaters in a complex way, but it's important to note that this is a very much non - canon and often controversial take on the 'Harry Potter' universe.
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.
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.
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.
Snape could be very cautious in his interactions. He would be constantly aware of the power dynamics. He might flatter the more powerful Death Eaters subtly to avoid suspicion. For instance, he could compliment Bellatrix on her loyalty to the Dark Lord. At the same time, he might try to intimidate the weaker ones to show that he's not to be trifled with. He might use his knowledge of the Dark Arts to his advantage in these interactions, like casually mentioning a difficult spell he's mastered to gain some respect.
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.
I'm not really sure if there are popular ones specifically. Fanfiction can cover a vast range of really odd and unique concepts, but the idea of male Death Eaters in diapers is rather strange and not a common mainstream fanfiction theme. It might exist in some very niche corners of the fanfiction world, but it's not something I've come across frequently.
