Well, it really depends on your taste. Some of these fanfictions might focus more on the magical elements that come with Harry being the son of Elrond in the Harry Potter universe. Others could be more about the relationships he forms. You have to dig through and read a few to find the really good ones. For example, some might explore how his elven heritage affects his magic in Hogwarts, which can be really fascinating.
In 'Harry Potter Son of Elrond' fanfiction, a recurring theme is the clash and融合 of cultures. The wizarding culture of Harry Potter and the elven culture associated with Elrond. This can lead to interesting scenarios in terms of magic use, social norms, and values. Another theme is the discovery of hidden knowledge. As the son of Elrond, Harry might have access to ancient elven wisdom that could change the course of events in the wizarding world. And of course, the theme of friendship is often explored, as Harry's new identity might attract different kinds of friends or allies.
Another theme is self - discovery for Harry. With the influence of the MC, Harry gets to explore different aspects of himself. For example, he might discover new magical abilities or gain more confidence in his identity as a wizard. In some fanfictions, the MC helps Harry to look beyond what he thought was possible for himself.
A 'Harry Potter adopts Naruto' fanfiction could see Naruto being amazed by the magic of the wizarding world. He might constantly ask Harry about how everything works. Harry would have to explain things like the Floo Network and thestrals to him. Naruto could also share his stories of the Hidden Leaf Village with Harry and his friends. This could lead to new friendships being formed, like Naruto becoming good friends with Ron and Hermione. And perhaps Naruto would use his shadow clone jutsu to help out during Quidditch matches, either by confusing the opposing team or helping to search for the Snitch.
Well, perhaps Harry could find Sasuke in a strange magical realm that connects the Naruto world and the wizarding world. Harry, being the kind - hearted person he is, decides to take Sasuke under his wing. He could introduce Sasuke to Hogwarts, and Sasuke might be amazed by the magic there. He would learn spells instead of ninjutsu, and they could have adventures together fighting against dark wizards who might be interested in Sasuke's special powers.
Love and acceptance are huge themes too. Harry has been through so much, and in these fanfictions, the oc shows him unconditional love and acceptance. It's not just about giving him a home, but also about accepting his flaws and his destiny. The oc often has to fight against the prejudices of the wizarding world to keep Harry safe and loved, which adds an interesting layer to the story.
At first, Sasuke would probably be very guarded. But Harry, being friendly, would try to break through that. Harry would show Sasuke around Hogwarts, and Sasuke might be a bit dismissive at first, thinking his ninja skills are superior. But as he sees the power of magic, he'd start to respect it. They would have conversations where Harry tries to understand Sasuke's past traumas, and Sasuke might be hesitant to open up. However, over time, they would bond, especially when facing a common enemy. Harry would use his quick thinking and magic, while Sasuke would use his combat skills.
One popular 'Harry Potter MC Adopts Harry' fanfiction is 'A Different Sort of Home'. In this story, the main character takes Harry in and provides a nurturing environment that is quite different from what he experiences in the Dursley's household. It delves into how Harry's character develops in this new setting, with the MC teaching him magic in unique ways and introducing him to a different side of the wizarding world.
His magical abilities might develop in a different way. The Malfoys could introduce him to different types of magic or magical artifacts. Maybe he'd learn more about the Dark Arts in a different context, not for evil purposes but just to understand it better. He could also become more skilled in areas like Occlumency earlier on, since the Malfoys might see it as an important skill to protect their family secrets. His relationship with his Gryffindor traits would be tested. He might still have his bravery, but it could be expressed in different ways, like standing up to the Malfoy family's wrongdoings.
