First, create a unique and complex original character (OC). Think about their backstory, like what led them to become a Death Eater. Maybe they had a difficult family life or were influenced by a powerful dark wizard. Second, understand the world of Death Eaters in the Harry Potter universe. Know their beliefs, their hierarchy, and how they operate. Third, focus on the character's internal conflict. Even as a Death Eater, they might have doubts or a moral compass that still tugs at them. This can make the character more interesting and the fanfiction more engaging.
Common themes in Death Eater OC fanfiction include the struggle between good and evil. Even though they are Death Eaters, there's often a part of the OC that still has some goodness. Love is another theme, whether it's a forbidden love with someone on the opposite side or love within the Death Eater community. And of course, the theme of identity. The OC may be trying to figure out who they really are, especially when they are involved in such a dark and complex group like the Death Eaters.
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.
One great 'oc death eater fanfiction' is 'The Dark Mark's Legacy'. It focuses on an original character who gets involved with the Death Eaters in a really interesting way. The character development is well - done and the plot keeps you on the edge of your seat.
Bellatrix Lestrange's younger brother or some other minor Death Eater character could be used. This would allow for the creation of a new character with his own motives and backstory. He could be betrothed to Hermione as part of a larger plot by Voldemort to gain control over Hermione's knowledge and magic. This would put Hermione in a very difficult position as she would be tied to a very dark and dangerous family.
There's also a possibility that it could be a minor Death Eater that we don't know much about from the original series. The author of the fanfiction could create a new character who was a Death Eater but is now having doubts. Hermione could be the one to find this person and start their journey of change. This would give the author a lot of creative freedom to develop the character's backstory and their relationship with Hermione.
First, you need to create a well - thought - out original character. Decide on their background, motives, and personality traits. For example, if your OC is a Death Eater, why did they join? Was it for power, family pressure, or something else? Then, plan out your plot. Maybe it could involve your OC's rise through the ranks of the Death Eaters or their conflict with other members.
It could be someone who has a hidden good side, like Draco Malfoy. He was from a Death Eater family but showed signs of not fully embracing the dark side. Maybe in this fanfiction, he decides to protect Hermione for some unforeseen reason, perhaps because he has developed a new understanding of the value of life and friendship.
In some fanfictions, Percy Weasley may be depicted as a Death Eater, but this is a departure from the original canon. Fanfiction allows for creative reinterpretations, and some authors might explore this dark turn for his character to add drama and new plotlines.
In this type of fanfiction, the relationship between Hermione and the Death Eater could be very complex. Maybe it starts as a hostile one, but as the story progresses, they might find some common ground or mutual understanding. It could also be a story of redemption for the Death Eater through Hermione's influence.
