Well, a frequently seen trope for fem OCs in Harry Potter fanfiction is the 'Chosen One' - like trope. She might be prophesied to do something great, similar to Harry. Then there's the 'Secret Heir' trope. She could be the heir to an old wizarding family or a magical place. Also, the 'Magical Savior' trope is common. She uses her unique magic to save Hogwarts or the wizarding world from a new threat. It's important to note that while these tropes are common, they can be used in new and interesting ways if you put your own spin on them.
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.
One common trope is the 'Mysterious Newcomer'. He arrives at Hogwarts and everyone is curious about him. Another is the 'Chosen One' trope, similar to Harry, where he has a special destiny or power. There's also the 'Rebel' trope, where the male OC doesn't follow the normal Hogwarts rules and causes some chaos. For example, he might start a secret club that practices unapproved magic.
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.
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.
One common trope is the 'lost heir' trope. The OC is often revealed to be the heir of some important clan or have a special bloodline. Another is the 'outsider who becomes a hero' trope. They start as an unknown in the Naruto world but through their skills and determination, they rise to prominence. The 'love interest for a main character' trope is also seen a lot, where the OC becomes romantically involved with Naruto or another main character.
One common role is that of an exchange student. They come to Hogwarts to experience the British way of magic and create cross - cultural friendships. This allows for a lot of fun interactions as they share their American magic knowledge with the Hogwarts students.
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.
Well, there's the trope of the fae heritage affecting her appearance. Maybe she has more elven - like features or her eyes change color. And there's the relationship trope. Her relationships with other characters can be greatly affected. For instance, a potential love interest might be initially drawn to her because of her unique fae allure, but then they have to deal with the complications that come with her different nature. There can also be a trope where the fae inheritance makes her a target for dark forces who want to use her powers for evil.
One popular trope is the 'fish out of water' scenario. A fem Harry Potter in the realm of Hades would be quite out of place. She'd have to adapt to the dark and often unforgiving world of Hades. Another is the 'powerful outsider' trope. Given Harry's magical abilities, she'd be a force to be reckoned with in Hades' domain. And the 'romantic entanglement' trope is also common, perhaps a relationship between fem Harry and Hades or one of his minions, adding a layer of drama and passion to the story.
One common trope might be Harry having multiple romantic interests at once. Since he's portrayed as a playboy, there could be a lot of flirting and love triangles. Another could be that he uses his fame in the wizarding world to his advantage in the dating scene. Maybe he gets special treatment from other characters because of his status, which then helps him in his 'playboy' ways.
One of the common tropes is the 'soul - bond' trope. In fanfiction, characters might be magically bonded at a soul level, which affects their relationship and actions. For example, Harry and Hermione could be soul - bonded, and it would change how they interact with each other and other characters. Another trope is the 'secret identity' trope. A character might have a secret identity or past that is slowly revealed throughout the fanfiction, adding drama and mystery. The 'reincarnation' trope is also seen sometimes, where a character is the reincarnation of someone from the past in the wizarding world.
