Power is a common theme. Fanfictions often explore how Voldemort amasses and uses his power, and how others react to it. For example, some stories might show characters trying to resist his power grab.
Another theme is the origin of Voldemort's evil. Some fanfictions go deep into his past, like his time at Hogwarts as Tom Riddle, to find the root of his malevolence. They might explore how his childhood experiences shaped him into the Dark Lord. This can be really fascinating as it gives more depth to his character than what we get in the original books.
Well, a major theme is the rediscovery of magic. In the original series, a lot of magic was used in the fight against Voldemort. In these fanfictions, magic can be used for more positive, creative things. Also, friendship is often explored in a different light. Without the dark shadow of Voldemort, friendships can form and develop based on different interests and personalities rather than just being part of a resistance against the Dark Lord.
A frequent theme is the breaking of boundaries. In the original story, Harry and Voldemort are on opposite sides of a huge divide. Fanfictions with this plot explore what happens when those boundaries are shattered. Also, there can be a theme of discovery. Harry discovers a new side to Voldemort that no one else has seen, and this leads to their relationship. And of course, there's the theme of transformation, both for Voldemort in terms of his character and for the whole 'Harry Potter' world view as a result of their relationship.
Well, a frequent theme is the exploration of opposites. Harry is the symbol of good and Voldemort of evil in the original story. In yaoi fanfiction, writers often play with this dichotomy, seeing how these two extreme characters could come together. Also, there's often a theme of secrecy and forbidden love, as their relationship would be frowned upon in the wizarding world.
Well, a common theme is the exploration of the characters' dark sides. Since both Harry and Voldemort have complex personalities, these fanfictions often dig deeper into their darker aspects. Also, there's the theme of alternative universes. Writers like to create different scenarios where the relationship between Harry and Voldemort can develop in ways that are not possible in the original story. For example, in some fanfictions, the wizarding world has a completely different power structure because of their relationship. There's also the theme of sacrifice, where either Harry or Voldemort might sacrifice something for the sake of their relationship.
One common theme could be the exploration of power dynamics. Voldemort is a very powerful character, and pregnancy could potentially change or add to that power dynamic. Another might be the idea of redemption or change, as pregnancy could force Voldemort to re - evaluate his goals and actions.
One common theme is the exploration of redemption. Voldemort, being the ultimate evil in the original series, is sometimes given a chance at redemption in these fanfictions when he works with Harry. Another theme is the power of cooperation across ideological divides. It shows that even the darkest and the lightest can come together for a greater good.
Love and hate are also common. The complex relationship between fem Harry and Voldemort can be filled with both love and hate. It could be a romantic kind of love or a more platonic love - hate relationship. Identity is another theme. Fem Harry may have a different identity in the wizarding world compared to male Harry, and this affects how she deals with Voldemort.
One common theme is power. Voldemort is always associated with his quest for power, and when his snake aspect is involved, it often symbolizes another layer of his power - something more primal and dangerous. For example, in many fanfictions, his control over Nagini is seen as a key part of his power structure.
One common theme is the power struggle. Since they are on opposite sides in the original story, their relationship as mates can create a complex power dynamic. Another is the idea of redemption for Voldemort.
One common theme is redemption. It often involves Voldemort getting a chance to redeem himself through his friendship with Harry. Another theme could be the exploration of power. How would their combined powers be used? Also, the theme of forgiveness might be present as Harry has to forgive Voldemort's past actions for the friendship to work.
