The redemption trope can also be found in some of these fanfictions. Voldemort might start to change his ways because of his relationship with Fem Harry Potter. It's an interesting take as it goes against his established character in the original series. And then there's the trope of the hidden identity. Fem Harry Potter could be hiding her true nature from Voldemort, which adds suspense and mystery to the story.
There are many fanfictions out there with this theme. In some, Voldemort's 'claiming' of Fem Harry Potter could be seen as a power play. He might be attracted to her unique power as a female version of Harry. It could also be a way to twist the original story's dynamic, creating a more complex and often dark relationship between the two characters.
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 trope is the 'New Student' trope. The fem OC arrives at Hogwarts as a new student, often with some mysterious past or special ability that makes her stand out. Another is the 'Love Interest' trope, where she becomes a love interest for one of the main characters, like Harry or Draco. There's also the 'Outcast' trope, where she doesn't fit in with the typical Hogwarts crowd due to her unique views or powers.
The theme of forbidden love also often appears. Given their status as enemies in the original story, the idea of them having some sort of romantic or deep emotional connection in fanfiction is a popular one. It adds an element of drama and tension to the story.
The theme of trust is often present. Given that Harry and Voldemort are usually enemies, when it's a female Voldemort, the story might focus on how they learn to trust each other or not. And the theme of changing fate. They might try to change the fate that would usually lead to their enmity, for example by working together to prevent a greater evil.
One common trope is the 'fish - out - of - water' situation. The fem Harry Potter character is suddenly in a very different world like Marvel, and she has to adapt. Another is the power - comparison trope, where her magic is compared to the superpowers in Marvel. For example, how her ability to apparate might be better or different from Quicksilver's speed.
The theme of redemption can also be found. There are stories where Voldemort might be on the path to some form of redemption through his interactions with fem Harry. Also, the idea of forbidden love or a strange attraction sometimes pops up. It's a very different take on the original relationship between Harry and Voldemort. It challenges the traditional view of good and evil. And in some fanfictions, there's the theme of sacrifice. Fem Harry might have to sacrifice something dear to her in order to defeat Voldemort or change his ways.
A frequent theme is the re - imagining of the magical world. With Voldemort in a different role as an adoptive father, the power dynamics in the wizarding world change. Also, the theme of identity is prominent. Fem Harry has to figure out who she is in this new situation where she is associated with Voldemort. And there's often the theme of moral ambiguity as she may be exposed to dark magic yet still hold on to her own sense of right and wrong.
One common trope is the redemption arc of Voldemort. In these fanfics, he goes from being the evil Dark Lord to a more caring figure. Another is Harry's struggle with his past abuse and how he slowly heals with Voldemort's new - found kindness.
The 'fish - out - of - water' trope can also be present. For example, if fem Harry is the one pregnant, she might struggle with the physical and emotional changes in a world that is still male - dominated in many ways. And Draco might be out of his element in dealing with a pregnant Harry, especially if it goes against his family's expectations. There could also be a 'found family' trope as they navigate this new situation together and form a new kind of family unit.
