What could be the plot of a 'Harry Potter adopts Sasuke' fanfiction?

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.

Well, one possibility is that Harry realizes Fenrir's tragic backstory and decides to help him change. Maybe he uses magic to suppress Fenrir's werewolf side and tries to integrate him into the wizarding society. Harry could teach Fenrir about friendship and loyalty, and together they fight against the dark forces that once exploited Fenrir.

Perhaps the girl is a huge fan of Harry Potter in the fanfiction world. When Harry discovers her, she's being bullied for her love of him and his story. So, he adopts her to protect her. He then shows her the real Hogwarts, not just the one she's read about. Along the way, they might face challenges from those who don't like the idea of Harry having an adopted daughter, but they overcome them together.

Maybe Aragorn adopts Harry because he sees the potential in him to be a great leader. He takes Harry under his wing to groom him into a leader who can unite different groups, just as Aragorn united the races in Middle - earth. Aragorn would expose Harry to the politics and power dynamics of Middle - earth, and Harry could use his own experiences of dealing with the wizarding world's power struggles to adapt and contribute. Also, Aragorn's strong moral compass would influence Harry to make more ethical decisions in his life.

One possible plot could be that Hawkgirl discovers Harry Potter in a dangerous situation in the wizarding world. Maybe he's being hunted by dark forces more intensively than in the original story. Hawkgirl, with her combat skills and unique abilities, decides to take Harry under her wing. She could teach him some of her fighting techniques, which would be a new aspect for Harry as he mainly focuses on magic in the original. This would lead to Harry having an edge in battles against the dark wizards and creatures.

In such a fanfiction, perhaps the plot could involve Harry seeing a child in a difficult situation, like an orphan in the wizarding world who has no family due to a dark wizard's attack. Harry, having been an orphan himself, feels a strong connection and decides to adopt the child. He then teaches the child about magic, love, and how to face the challenges in the wizarding world.

The plot could involve a prophecy that ties Tsuna and Harry together. Harry, being the hero he is, feels responsible for Tsuna. He adopts Tsuna and brings him to live in the wizarding world. Tsuna is amazed by all the magical things around him, from the moving portraits to the flying broomsticks. Harry teaches Tsuna about the dark forces in his world and how to fight them. Tsuna, with his own tenacity, starts to train hard. Along the way, they make new friends together and face many challenges that test their bond and their magical abilities.

Well, it could be that the kid has some special powers just like Harry. Harry sees himself in the kid and decides to take him under his wing. Maybe the kid is an orphan too, and Harry wants to give him a better life at Hogwarts, away from the cruel muggle world that didn't understand him when he was a kid.

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 Potter arrives in Gotham City and is appalled by the state of it. He decides to adopt some of the children who are in difficult situations. As he does this, he uses his Hogwarts education and magical skills to protect them from the likes of the Penguin and other villains. He might even introduce some magic into Gotham's society in a very subtle way, like using spells to improve the living conditions in the slums where he and the adopted kids live.
