Yes, it can be quite a popular concept in some fanfiction circles. The idea of turning a heroic character like Harry into a Death Eater is a very interesting and controversial twist. It allows for exploring different aspects of the Harry Potter universe, such as what would happen if the power of the Dark Side had swayed him. It also makes for some very intense and dramatic storylines as his relationships with other characters would be completely upended.
One possible scenario in such a fanfiction could be that Sirius is somehow forced or tricked into becoming a Death Eater. Hermione might then try to rescue him from the dark side. Maybe she discovers some ancient magic that can reverse the dark mark's influence on him.
I don't think it's a popular fanfic concept. Harry Potter is known for his courage and determination to fight against Voldemort and his Death Eaters. The original story has built up a strong moral framework where the Death Eaters are the villains. Turning Harry into someone who is a fan of them would completely distort the character and the values that the series represents. Most fans would probably find it hard to accept such a deviation from the established canon.
Yes, it can be a popular concept in the Harry Potter fanfiction world. Many fans enjoy seeing the hero, Harry Potter, take decisive action against the villains, the Death Eaters. It gives a sense of ultimate victory and justice.
No. In the original 'Harry Potter' series, Harry is the hero who opposes the Death Eaters. Fanfiction might distort this, but it goes against the essence of the original story.
One common theme is the struggle for identity. Fem Harry is often caught between her old self and the new identity she's taking on as a Death Eater. Another theme is power. How she gains, wields, or is corrupted by power within the Death Eater hierarchy.
One interesting 'Harry Death Eater fanfiction' could be where Harry is secretly a double agent among the Death Eaters. He uses his position to gather information for the Order of Phoenix. Another might involve a Death Eater having a change of heart because of Harry's actions and trying to redeem themselves.
Another important theme is the exploration of the grey area between good and evil. In the original Harry Potter series, the divide between the good guys and the Death Eaters (the bad guys) is quite clear. But in fanfiction, authors often like to explore that middle ground. They show that not all Death Eaters may be completely evil, and Harry may have to make difficult decisions about who to trust and what is truly right or wrong in a more complex moral landscape that includes the Death Eaters.
Well, there's the theme of secrecy. Since the Death Eaters operate in the shadows, a lot of fanfictions play with the idea of hidden identities and secret agendas. Another common one is the theme of family. Some Death Eaters have family members who may or may not support their actions. And of course, the theme of good vs evil is always present, as the Death Eaters are on the 'evil' side in the wizarding world.
Bellatrix Lestrange is also a likely candidate. Her encounter with Hermione would be extremely intense. Given her loyalty to Voldemort and her rather unhinged nature, she would likely pose a serious threat to Hermione, but Hermione might also find a way to use Bellatrix's madness against her.
It's a rather concerning concept. In the 'Harry Potter' world, Hermione is a role model for many with her courage, knowledge, and tenacity. The idea of her being submissive to a Death Eater is not only out of character but also has the potential to introduce negative and disturbing ideas into the fanfiction community. Fanfiction should usually build on the positive aspects of the original work, not create such counter - intuitive and potentially offensive scenarios.
