Well, in the world of fanfiction, just about any concept can be explored, so it's highly likely that there is a 'harry potter is loki reincarnated' fanfiction. Writers love to mash up different universes and characters. This particular concept could bring in elements of Loki's mischievous nature into Harry's character, creating a whole new set of adventures and challenges for him in the Hogwarts setting.
Well, a possible plot development is her struggle with identity. Since she has the memories of Harry but is now a girl, she may have an internal conflict. She might wonder if she should still follow the same path as Harry did in the original story. Also, in terms of magic, she could discover new ways of using magic that were perhaps not explored by Harry because of the different way she experiences the magical world as a female. For instance, she could have a special connection with certain female - centric magical creatures or spells that are more attuned to her new gender. And her presence as a girl could inspire other female characters in the wizarding world to be more assertive and strive for more equality in magic education and other aspects.
The character becomes more empathetic perhaps. As a girl, she might be more in tune with her emotions and those of others around her. For example, she could be better at consoling her friends when they're in trouble compared to Harry in the original. Also, her physical appearance as a girl might make her more approachable to some characters who were initially intimidated by Harry. This could lead to new friendships or alliances.
In addition to the obvious ones, there could be new characters introduced in the fanfic. Maybe a female mentor figure who helps Harry understand her new identity as a girl in the wizarding world. There could also be other female students who become closer friends with Harry in this new form. They could support each other in dealing with the challenges of being a girl in Hogwarts, like the pressure of looking a certain way or the boys - related drama that might come up.
I really like 'A New Beginning for Harry Potter'. In this fanfic, the reincarnated Harry has a different perspective on his role in the wizarding world. The story dives deep into his relationships with the other characters like Hermione and Ron, and how he tries to prevent some of the tragedies that happen in the original series. It's a great read for any Potter fan.
Harry Potter himself is a popular choice. Writers often explore what would happen if someone else's soul was in Harry's body and how that would change the story. Hermione Granger is also a common one. Reincarnating as her gives the chance to delve deeper into her intelligence and how she could use it in different ways. Another popular character to be reincarnated as is Draco Malfoy. It allows for a different perspective on the Slytherin house and the Malfoy family's role in the wizarding world.
One interesting plot could be that as a girl, Harry has to face different social expectations in the wizarding world. For example, in the original story, male and female characters might have different roles in some classes or traditions. As a reincarnated girl, she could break those stereotypes and show that gender doesn't limit one's magical abilities. Maybe she becomes more empathetic in this new form and uses it to her advantage in dealing with her friends and enemies alike.
One idea could be that Merlin, with all his ancient magic knowledge, reincarnated as Harry Potter would be able to quickly master spells at Hogwarts. He might even introduce some long - lost magic that was known in his previous life. For example, he could have a unique way of handling potions that was based on his experiences in Camelot.
There's also 'Reincarnated into Harry Potter's World'. In this fanfiction, the oc brings in new perspectives and interactions within the existing Harry Potter universe. It's full of creative interpretations of magic and how the oc influences the events that we know from the original series. For example, they might change the way certain relationships form among the characters.
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.
