One common theme is power dynamics. Given Bellatrix's loyalty to Voldemort and her powerful magic, and Harry being the 'Chosen One', exploring how power plays out between them can be interesting. Another could be redemption, where Bellatrix might be redeemed through her interactions with Harry.
Yes, there are some. You can try searching on fanfiction platforms like Archive of Our Own. There you might find various interpretations of the relationship between Harry and Bellatrix in the form of fan - made stories. However, keep in mind that the relationship between them in the original 'Harry Potter' series is quite complex and often antagonistic, so these fanfics can be very different from the canon.
One great 'Harry Potter x Bellatrix fanfic' is 'The Unlikely Bond'. It explores a very different relationship dynamic between Harry and Bellatrix. It shows how Harry, in this fictional scenario, tries to understand Bellatrix's twisted mind and in the process, they develop a strange connection that is full of tension and mystery.
One of the main themes is the exploration of redemption. Bellatrix is a character who has committed many heinous acts, and in some fanfics, Harry becomes the catalyst for her possible redemption. Another theme is the power of connection. Despite their differences, they are drawn to each other in some fanfictions, showing that even in the wizarding world, unexpected connections can form.
It's not appropriate. The 'Harry Potter' series has a certain moral and ethical framework. Fanfics that involve sexual scenarios between its characters distort this framework. Moreover, Bellatrix is a villain and such a relationship in a fanfic is not only inappropriate but also a strange and unethical interpretation of the characters.
Well, power dynamics is a big theme. Bellatrix is a powerful witch, and Harry has his own unique powers. Fanfics might show how they use or struggle with their powers in relation to each other. Also, the theme of forbidden love sometimes pops up. The idea that Harry and Bellatrix, who are on opposite sides, could have some sort of romantic or at least a very strong emotional connection that goes against the norms of their world.
Sure, there is. A lot of fanfiction writers are drawn to the idea of pairing Harry Potter and Bellatrix because of the extreme contrast between them. One story I read had Bellatrix under a spell that made her forget her allegiance to Voldemort, and she ended up helping Harry. This led to a series of events where they started to see each other in a different light, and the fanfiction explored their evolving relationship in great detail.
One popular 'harry x bellatrix fanfiction' is 'The Dark Mark's Legacy'. It delves into an alternate universe where Harry and Bellatrix have a complex relationship that goes against the norm of their traditional enmity in the original series. The story is filled with intrigue as it explores how their interactions change the course of the wizarding world.
I'm not a big fan of this pairing in a romantic or 'lemon' context as it's quite an unusual and often not in line with the original spirit of the 'Harry Potter' series. However, you can try searching on some fanfiction websites like Archive of Our Own. There might be some stories there, but keep in mind that such pairings can be controversial among fans.
Hermione could be included. She might be suspicious of Harry's interactions with Bellatrix and try to interfere or help, depending on the situation. Her intelligence could also be crucial in understanding any strange magic related to Bellatrix.
