A big theme is the exploration of gender roles. In the wizarding world, there are certain expectations for male and female wizards. A female Harry Potter in an orphanage would have to navigate these. Also, the theme of resilience is common. The orphanage is a tough place, and she has to be strong to survive and then face the challenges of the wizarding world. For instance, she might have to deal with bullies in the orphanage who target her because she's different.
The theme of discovery is often present. She discovers her magical powers while in the orphanage, which is different from the original story. There's also the theme of family. In the orphanage, she might long for a real family, and when she enters the wizarding world, she has to figure out what family means to her. Maybe she forms a family - like bond with her Hogwarts friends instead of relying on blood relations as much as the male Harry Potter did.
One common theme is the struggle for identity. Since she's a girl in a world that expects a male hero like in the original Potter story, she has to figure out who she is. Another theme is the power of friendship. In the orphanage, she might meet other misfits and form strong bonds. For example, she could befriend a girl who has some sort of latent magical ability too.
Another could be 'A Female Potter in the Orphanage: A New Perspective'. This fanfic might focus on how the wizarding world perceives a female version of Harry Potter when she is found in the orphanage. It could explore how her femininity affects the way she is treated by Dumbledore and other key characters, and how she might break gender stereotypes within the magical community.
One common theme is the exploration of power dynamics in relationships. For example, a female character might be submissive to a more powerful male wizard. Another theme could be the female character sacrificing her own desires for the sake of the relationship or the greater good within the wizarding world. Also, there may be themes related to loyalty and devotion in a submissive way, like a female character always following and supporting a male character's decisions without question.
Friendship is a very common theme. Female characters often start as friends or comrades and then their relationship deepens. For example, they might start as study partners in a magical subject and then realize they have a stronger connection.
One common theme is the struggle between her human side and vampire side. For example, she might resist the urge to drink blood because of her human values. Another theme could be isolation. Since she is now different, she might feel alone even among her friends at Hogwarts.
I've read a fanfic where the female Harry Potter in the orphanage has a special connection to animals. In this story, she befriends a stray cat in the orphanage yard, and later discovers that the cat is actually a magical familiar sent to protect her. The orphanage setting in this fanfic is really well - described, with its dreary halls and mean caretakers. The story shows how her gender might lead her to be more empathetic and nurturing towards the cat, which in turn helps her unlock her magical abilities.
One common theme is the clash of cultures. The Russian Prince often brings his own set of values and magical practices that contrast with the British ones in the Harry Potter universe. Another theme could be friendship or rivalry with Harry Potter and his friends. Sometimes, the Russian Prince is portrayed as a love interest, which adds a romantic element to the story.
One common theme is the exploration of different gender roles. For example, how a female Harry Potter would navigate the male - dominated wizarding world. Another theme is new romantic relationships. With a gender - swapped character, different pairings become possible. Also, there's often a focus on how the character's personality might be different or the same in a different gender. For instance, a male Hermione might have a different way of expressing her intelligence.
One common theme is the power dynamic. Lucius is an established and often feared figure in the wizarding world, while Harry is the emerging hero. Another theme is the clash of ideologies, with Lucius representing the pure - blood supremacy ideas and Harry standing for equality. And there's also the theme of mystery, as both characters have their own secrets that can be explored further in fanfics.
One common theme is redemption. Since Narcissa was part of the Death Eaters' circle, many fanfics explore her journey towards redemption, like making amends for her past actions. Another theme is family. Narcissa's love for her family, especially Draco, is often a central focus, showing how far she'll go to protect them.
One common theme is the exploration of relationships. For example, when Harry is pregnant, it often tests and deepens his relationship with the other characters, like his friends or romantic partners. Another theme is the struggle against prejudice. In the wizarding world, a male pregnancy might be seen as abnormal, so the fanfics may show how Harry and those around him face such social attitudes.
