Well, perhaps in this fanfiction, Harry, being from the wizarding world, uses his magic to somehow enter Sasuke's world. He might see Sasuke's troubled past and decide to take him in. Harry could then teach Sasuke about magic, which would be a huge culture shock for Sasuke. And they could form a bond over their shared experiences of loss and the need to prove themselves.
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.
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.
Harry is likely to be his usual self - brave, kind - but also a bit more nurturing as he's adopting Sasuke. He would be patient in dealing with Sasuke's often cold and aloof exterior. Sasuke, on the other hand, would be his brooding self at first. He's full of vengeance in his original story, but in this fanfiction, he might start to let go of some of that as he experiences Harry's care and the new world of magic.
The fanfiction would likely show a different side of their development. Since Kakashi is a very experienced ninja, he could expose Naruto and Sasuke to different types of missions earlier. This would accelerate their growth not only in terms of combat skills but also in terms of understanding the ninja world. And with Kakashi as their adoptive father - figure, they would have a stronger emotional support system, which could potentially prevent some of the tragedies that happened in the original story.
Protection is also a big theme. Naruto is always protecting Sasuke in these stories, whether from external threats or from Sasuke's own inner demons. It's like Naruto is a shield for Sasuke. And friendship is there too. Even though Naruto is in a father - like role, the essence of their friendship from the original story is still there, just in a different form.
The theme of growth is very common. All three characters - Naruto (the adopter), Naruto (the younger self) and Sasuke - experience personal growth. They learn from each other, share their skills and knowledge. For example, Naruto might teach Sasuke some new jutsu, while the younger Naruto learns about the importance of friendship from Sasuke. This mutual growth is what makes these fanfictions interesting.
Well, 'Naruto's Family Expansion' is also a notable one. This fanfiction not only shows Naruto adopting Sasuke but also how it impacts the entire village. It has some heart - warming scenes where the villagers slowly accept Sasuke as part of Naruto's family, and it also includes some action scenes where they fight together to protect their new - found family.
It would be very close. Kakashi would be like a father or an older brother to them. Naruto and Sasuke would respect and rely on him. They would probably have a more harmonious relationship with each other too, because Kakashi would be there to mediate any conflicts.
One popular 'Naruto adopts Naruto and Sasuke' fanfiction might be 'A New Family in Konoha'. In this kind of fanfiction, it often explores unique relationships. It could show Naruto in a different light, perhaps as a more mature figure taking care of his younger self and Sasuke. It might involve them training together in new ways and dealing with the challenges of the ninja world while having this unorthodox family dynamic.
