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.
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.
If Loki were to enter the Harry Potter world, it could significantly disrupt the plot. His ability to deceive and manipulate could lead to many characters making wrong decisions. For instance, he could trick Dumbledore into believing a false prophecy, which would send Harry and his friends on a wild goose chase.
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.
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.
The relationship could be quite complex. Loki might see Harry as an interesting project, someone he can mold to his own liking. Harry, on the other hand, might be initially wary of Loki but gradually come to respect his skills. They could have a mentor - mentee relationship where Loki imparts his knowledge but also tries to influence Harry's actions.
In 'Harry Potter son of Loki' fanfiction, Harry changes significantly. His sense of identity is greatly shaken. He no longer just sees himself as a simple wizard. He now has this connection to Norse mythology. This makes him more curious about different forms of magic and otherworldly things. He may become more of an outcast as well, since his heritage is so different. But this also makes him stronger in some ways. He has to rely on himself more and develop his own unique set of skills and powers that come from both his Potter and Loki lineage.
One common theme is the clash of different magical systems. Since Loki comes from Norse mythology and Harry Potter has its own detailed magic system, seeing how these two interact is a big part of many fanfictions. For example, Loki's magic might be pitted against the spells of Hogwarts.
