Well, it's very possible. Given the popularity of both the Harry Potter series and the Norse mythology with Thor and Loki, some fans might have been creative enough to write such a crossover. However, not all fanfictions are easy to find. You may need to use specific search terms and filters on the relevant platforms to locate one. It might also depend on how new or old the fanfiction is. Some older ones could be buried deep in the archives, while newer ones might be more visible if they gain popularity quickly.
One possibility could be a story where Harry Potter, being the son of Loki, has a different set of magical abilities. He might be more mischievous like Loki and this could lead to some interesting interactions with the wizarding world. In this fanfiction, his encounter with Percy Jackson could be a clash of two different mythologies. Maybe they start as rivals but then realize they have to work together to face a common threat.
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 possible plotline could be Harry's struggle with his dual heritage. He has to deal with the wizarding world of Harry Potter and the Norse mythology world of Loki. For example, he might face challenges in learning magic in a way that combines both magical systems. Another plotline could involve his relationships with other characters. Since he is the son of Loki, he might have a more complex and devious side to his personality, which could create interesting dynamics with his friends like Hermione and Ron. They might be initially suspicious of his motives at times.
A potential plot might involve Harry being thrust into the Norse realm due to his heritage. There, he could face challenges from the other Norse deities who might not accept him as Thor and Loki's son. Meanwhile, back in the wizarding world, Voldemort could sense his newfound power and see him as an even greater threat. Harry would then have to navigate between two worlds, trying to gain acceptance in the Norse realm and also defeat Voldemort in his own world. He could also discover new magical abilities related to his Norse blood, such as the ability to communicate with certain Norse magical creatures or use runes in a more powerful way than regular wizards. And his relationship with his friends in Hogwarts would change as they try to understand his new identity.
Another aspect could be his connection to the Norse world. Maybe he gets visited by other Norse deities or creatures. He could be sought after by some of Loki's enemies in the Norse realm who think he's a threat because of his relation to Loki. This would add a whole new layer of danger and adventure to his life at Hogwarts.
Well, it could be a very interesting and strange crossover. Maybe in this fanfic, Harry from Harry Potter and Harry (assuming it's a different character also named Harry) meet Loki from the Marvel universe and they somehow have a son together in this fictional story. It could involve magic from the Potterverse and the trickery of Loki combined with the new element of their son having unique powers or a special role to play.
One possible plot could be that the son is lost in a strange dimension that combines elements of the Harry Potter world and Loki's world. Harry Potter and Loki have to team up to find him. Along the way, they face various challenges like magical creatures from the Potterverse and Loki's enemies. The son, when found, might have developed some unique powers that are crucial for saving both their worlds.
In fanfiction, the idea of Harry being Loki's son can be a really interesting concept. It might bring together the magical world of Harry Potter and the Norse mythology of Loki. However, in the original Harry Potter and Norse mythologies, there is no such relation. But in fanfiction, authors can use their creativity to build a whole new story around this idea, perhaps with Harry having some of Loki's trickster traits and magical abilities from a different source.
A possible plotline is that Harry grows up in a world where magic and technology co - exist. He uses his combined heritage to solve mysteries that neither wizards nor superheroes could alone. For instance, he might use his knowledge of magic to fix a malfunctioning Stark tech device that has been enchanted. Or he could use Stark - made gadgets to enhance his magic in battles against dark wizards. His relationships with characters like Hermione and Thor would also be central to the story, as they help him understand his two sides.
