In most traditional mythologies, Percy Jackson is the son of Poseidon in the 'Percy Jackson' series, and Odin is from Norse mythology. But in fanfiction, anything can be reimagined. So, he could be depicted as the son of Odin in some very creative fan - made stories.
There is definitely some 'Harry Potter Son of Odin' fanfiction. However, the quality can vary greatly. Some stories might focus more on how Harry's new identity as the son of Odin affects his relationships at Hogwarts, like with his friends Hermione and Ron. Others could explore how his new powers or abilities, stemming from his divine parentage, change the way he faces the challenges in the wizarding world. It's really a matter of sifting through different works to find the ones you like.
The plot might involve Naruto being a son of Odin and having to deal with the expectations and responsibilities that come with such a heritage. He could be caught between the ninja world he grew up in and the world of Norse mythology. For example, he may need to reconcile the values of the shinobi with the values of Asgard. There could also be a conflict where he has to face off against enemies who are after the power he inherited from Odin. This could lead to him going on a journey to learn more about his true father and the powers he possesses, all while still trying to keep his identity as a ninja intact.
It would probably be a very interesting mix of the Harry Potter and Norse mythology universes. Maybe Harry would have some of Odin's powers, like the ability to see the future or great wisdom. He could also have a different kind of magic, more in line with Norse magic, which could make for some really cool battle scenes or problem - solving in the story.
In this fanfiction concept, it could be that Odin had a secret mission in the Naruto world. He might have fallen in love with a kunoichi there, perhaps someone with special powers or a noble lineage. Their union could have led to Naruto's birth. It would also mean that Naruto would potentially have some latent god - like powers from Odin that could be explored in the story, like enhanced strength or the ability to control some Norse - inspired elements.
In some fanfictions, Percy as Odin's son could be involved in a power struggle within Asgard. Maybe there are those who don't believe he is worthy of his status, so he has to prove himself not just to them but also to himself. He might have to learn new magic or fighting techniques specific to Asgardian culture to gain respect.
The common themes in 'Harry Potter Son of Odin' fanfiction can be quite diverse. One is the clash of cultures. You have the very British wizarding culture of Harry Potter and then the Norse - influenced by Odin - culture. How these two cultures interact and sometimes clash is an interesting theme. Another theme is the search for self - understanding. Harry has to figure out who he is now that he has this new identity. Is he still the same Harry Potter who grew up in the cupboard under the stairs? And there's also the theme of loyalty. His friends in the wizarding world might be a bit skeptical or even scared of his new identity, and he has to decide where his loyalties lie - with his old friends or with this new part of himself that is related to Odin.
His friends from the Leaf Village like Sasuke and Sakura could be his allies. They have always been by his side in the original story and would likely support him even with this new twist.
He could have interesting interactions with Issei. Naruto's more selfless nature compared to Issei's pervy tendencies could lead to some humorous and also teaching moments. Maybe Naruto would try to get Issei to focus more on noble goals rather than just chasing girls.
Well, if we think about it, in this fanfiction Naruto as Odin's son would likely have some unique abilities. He might be able to use some Asgardian magic along with his chakra. When it comes to his relationship with Natasha, it could be a friendship based on mutual respect for each other's combat abilities. They could learn from one another, like Naruto teaching Natasha some of his ninja stealth techniques and Natasha showing Naruto how to handle modern weapons. It would be a cool dynamic to explore in the fanfiction.
