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.
A popular trope is the 'teacher - student relationship' explored in a different way. Maybe a student has a closer or more complex relationship with a teacher than in the original books. There's also the 'enemies - to - lovers' trope, which is quite common especially for characters who were enemies in the original story like Draco and Hermione. And the 'lost - heir' trope, where a character discovers they are the heir to an important wizarding family or a powerful magical object, which then drives the plot of the fanfiction.
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 common trope is the 'alternate universe' where the story takes place in a different setting than the original books. For example, a modern-day muggle world with hidden wizarding elements. Another is the 'character redemption' trope, like Draco Malfoy being redeemed and becoming friends with Harry. And the 'power - up' trope is also seen, where a character discovers new and greater magical abilities.
One common trope in uncaring Harry Potter fanfiction might be the divergence from Harry's usual empathetic nature. For example, he could be written as being aloof towards his friends. This could be used to explore different character dynamics, like how Hermione and Ron would react to a less caring Harry. Maybe they would try harder to get his attention or become frustrated with him.
One common trope is the 'alternate universe' where things are drastically different from the original series, like if Voldemort won the war. Another is the 'character redemption' trope, for example, Draco Malfoy getting a chance to be a good guy in a different way. And there's also the 'romantic pairings' trope, like Hermione ending up with someone other than Ron in some fanfictions.
Well, a typical trope is the main character having special abilities due to their reincarnation. This could be something like enhanced magic skills or the ability to understand ancient magic more easily. For instance, they might be able to cast spells without a wand more effectively than others. Another common thing is that they often have a different perspective on the Hogwarts houses. Instead of the usual biases, they might see the value in all houses and try to bridge the gaps between them. And, of course, there's the trope of falling in love with a character in a different way than in the original story. Maybe the reincarnated character ends up with someone who was just a minor character in the original.
In femdom Harry Potter fanfiction, there are several common tropes. There's the 'dominant female love interest' trope, where a female character becomes the love interest of a male character but in a very dominant way. Then there's the 'female - led secret society' trope, where a group of female wizards form a secret society and dominate the male wizards. And the 'female - imposed magical training' trope, where a female wizard takes it upon herself to train a male wizard in a very strict and dominant manner, often pushing his limits both magically and personally.
A frequent trope is the 'school rivalry' taken to an extreme. In fanfiction, it can turn into full - blown battles between houses. There's also the 'magical creature as a sidekick' where a character befriends a really rare or powerful magical creature that helps them out. And the 'evil twin' or 'dark alter - ego' trope. A character might have a hidden, darker side that emerges and causes chaos, similar to how Harry had to deal with Voldemort's connection to him.
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 making Hermione overly bossy or annoying in a way that's out of character. For example, some fics might have her constantly nagging Harry and Ron without the nuanced friendship they actually have in the original books. Another is to downplay her intelligence and make her seem like she's just showing off rather than truly being brilliant.
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.
