Love and friendship are also explored. It could be a romantic relationship between the female OC and Bellatrix, which is often a very complex and dark love given Bellatrix's character. Or it could be a friendship where the OC manages to break through Bellatrix's tough exterior and form an unexpected bond.
One common theme is the power dynamic. Bellatrix is a powerful witch in the Harry Potter universe, so exploring how a female OC interacts with her in terms of power, whether it's challenging her, learning from her, or being in a power struggle, is quite popular.
Redemption arcs can also be a theme. Some fanfictions might focus on the female OC trying to redeem Bellatrix or at least understand the reasons behind her actions and evil nature. It could involve the OC showing Bellatrix a different way of life or a different perspective.
One common theme is redemption. The oc often tries to bring out a better side of Bellatrix. For example, in some fics, the oc's kindness makes Bellatrix question her dark actions.
A big theme is the battle between nature and nurture. Just because he's Bellatrix's son, does he have an inborn inclination towards dark magic? Fanfics often explore this. Family legacy is also a major theme. He has to deal with the reputation of his family. And there's the theme of acceptance. How does the wizarding world accept or reject this OC who has such a dark - associated lineage?
Another theme could be the exploration of the dark side. Hermione is a good - natured character, and Bellatrix's seduction could be a way to show how the dark side can be alluring and how Hermione might resist or be tempted by it. It could also involve themes of loyalty, as Hermione has to decide between her loyalty to her friends and the allure of what Bellatrix offers.
Common themes include the exploration of good vs. evil in a more personal way. Since Bellatrix is a Death Eater and Hermione is a Gryffindor, their kiss can symbolize a blurring of those moral lines. Also, there's often a theme of transformation. Hermione might be seen as having the power to transform Bellatrix, or vice versa. And the theme of secrecy is also there, as such a relationship would have to be kept secret in the context of the wizarding world.
One common theme is her relationship with the Dark Lord. Writers often explore how she became so devoted to Voldemort at a young age. Another theme is her time at Hogwarts. It could be about her studies, her friendships or rivalries there. And her family influence is also a big theme. How did growing up in the Black family shape her into the person she became later?
One common theme is loyalty. Both are associated with Voldemort, but in different ways. Snape is a double - agent, and Bellatrix is blindly loyal. Their interactions around this loyalty can be a major theme. For instance, how Snape hides his true loyalty from Bellatrix.
One common theme is the exploration of power dynamics. Bellatrix is a powerful Death Eater and Harry is the Chosen One. Fanfictions often play with how their powers interact and how they can either oppose or complement each other.
One common theme is her origin story. Writers often explore how she became the dark witch she is in the 'Harry Potter' series. Another theme is her relationships, like with her family or potential friends during her youth. For example, her relationship with her sisters might be a central focus.
Survival is a prevalent theme. Given Bellatrix's murderous and unpredictable nature, Hermione often has to fight for her survival in these fanfictions. It could be a physical fight, or a mental battle as she tries to outmaneuver Bellatrix in a dangerous situation.
A common theme is power struggle. Bellatrix is a powerful and dark witch, and Hermione is also very powerful in her own way with her intelligence and magic skills. So, there's often a back - and - forth as they try to assert their influence over situations or each other.
