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.
One possible plot could be that Harry starts to show Loki - like traits early on at Hogwarts. He might use his trickery to outwit his enemies, like the Malfoys. Maybe he even uses some of Loki's shape - shifting abilities in a magical way to get out of tricky situations during his adventures.
Loki is a powerful Asgardian with abilities that are more in the realm of the supernatural in a different way than Harry's magic. But Harry has a strong will and has faced some extremely tough opponents. In a fanfiction, if the writer decides to give Harry access to some of the most powerful and ancient magic in the wizarding world, he could be more powerful. For example, if he could use the magic that created the Hogwarts itself, he might be able to stop Loki quite effectively. Also, Harry has the support of his friends and the entire wizarding community behind him, which could give him an edge in power.
It's hard to say. Loki has a wide range of magical abilities from Asgard. He can shape - shift, create illusions, and has a certain level of telekinesis. However, Harry Potter has the power of love and friendship on his side, which has proven to be a very strong force in his world. Also, Harry is very skilled at defensive and offensive magic within the wizarding world. So it really depends on the situation.
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.
Yes, there are likely to be some. Fanfiction is a vast world and many creative writers combine different fictional universes like Harry Potter and Norse mythology. You can try searching on popular fanfiction websites such as Archive of Our Own or Fanfiction.net.
One idea could be that Loki, being the mischievous character he is, finds his way into the wizarding world of Harry Potter. He could start causing chaos in Hogwarts, perhaps by disguising himself as a student or a professor and playing pranks that are far more elaborate than those of the Weasley twins. For example, he might turn the entire Great Hall into an ice rink during breakfast time.
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.
Loki's mischievous personality could make Harry more adventurous. Harry might start to take more risks in his magical studies and in facing Voldemort. For example, he could be more willing to try out untested spells or strategies.
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.
