The clash of personalities. Harry is known for his good - heartedness and Lestrange is often seen as a more complex, perhaps darker character. When they interact in fanfic, it creates a really interesting dynamic.
In Harry Lestrange fanfic, the exploration of different magical elements is exciting. Writers can create new spells or magical artifacts related to both Harry and Lestrange's stories. Also, the potential for alternate universes where their relationship could be completely different from the original story is really appealing. For example, in some fanfics, they might be allies against a greater evil that was not part of the original plot. It gives a fresh perspective on the wizarding world and its characters.
The vastness of the Harry Potter world. It has so many elements like Hogwarts, Quidditch, the Ministry of Magic, etc. that are not related to the Lestranges at all. It's about Harry's journey, not just some side - story related to the Lestranges.
One idea could be that the OC Lestrange is a distant relative who has been kept in the dark about the family's dark deeds. They could start at Hogwarts and gradually discover the truth, leading to an internal struggle between loyalty to family and doing what's right. For example, they might find out about the Horcruxes and have to decide whether to help Voldemort or oppose him.
There could be a fanfiction where Lestrange has a change of heart. Maybe she meets a group of students who show her kindness and she starts to question her loyalty to Voldemort. This could lead to a whole new path for her character, full of internal struggles and moral dilemmas.
One interesting fanfiction could be where Bellatrix has a change of heart due to some magical accident and ends up helping Harry Potter secretly. In this type of story, there could be a lot of internal conflict for Bellatrix as she battles her loyalty to Voldemort and her newfound sense of morality. Another might be a time - travel fanfic where Harry goes back in time and has to deal with a younger Bellatrix, trying to prevent her from becoming the dark witch she is in the original timeline. There are also fanfictions that explore a more complex relationship between them, perhaps a forbidden friendship that develops against all odds.
Perhaps a plot where Harry tries to understand Bellatrix Lestrange's family better through his betrothal to a Lestrange. He could discover secrets about the family that change his perspective on the wizarding world's power dynamics. It might involve him delving into the family's past, their dark magic practices, and how he can either change or adapt to being part of that family in a way. This could lead to all sorts of adventures and self - discovery for Harry.
She might be motivated by a long - lost connection. For instance, if there was a family tie between Harry and her that she was previously unaware of. Or perhaps she has a change of heart after seeing the true nature of Voldemort's actions and decides that Harry is the only hope to stop the chaos and destruction Voldemort is causing. It could also be that she is magically bound to save Harry due to some ancient spell or prophecy that she discovers.
The uniqueness lies in the exploration of different themes. It can be a study of the nature of good and evil as represented by Harry and Rabastan. Fanfic writers can create scenarios where the boundaries between the two are blurred. Also, the cultural and family backgrounds of the two characters are vastly different. Harry's upbringing in the Muggle world and Rabastan's in a pure - blood, dark - magic - inclined family offer a rich ground for exploring how these differences can either clash or create an unexpected harmony. This combination of elements makes Rabastan Lestrange x Harry Potter fanfics stand out.
The fact that it's a fanfic means the author has a lot of creative freedom. They can create unique relationships between Harry and Namekian characters. For example, Harry could be mentored by a wise Namekian elder, which would add an interesting dynamic to the story. Also, exploring how Harry adapts to the Namekian environment and their way of life could be really engaging.
The potential for character growth. In a Fleur and Harry fanfic, both characters can grow in ways that are different from the original series. Harry can learn more about the wizarding world outside of Hogwarts and England through Fleur, and Fleur can develop a deeper understanding of the true heroism that lies within Harry, rather than just his fame as the boy - who - lived.
The unique relationship. It's not a common pairing in the original Harry Potter series. So seeing how the author weaves a story around Harry and Nana can be really fascinating.
