Well, a plot could be that Snape adopts Harry due to some unforeseen circumstances. For example, Dumbledore in his infinite wisdom decides that Snape is the best person to protect Harry. Snape initially hates the idea but as he spends time with Harry, he starts to see Lily in him, not just in appearance but in his kind heart. This makes Snape more protective. Harry, for his part, is initially scared of Snape but soon realizes that Snape is actually trying to help him grow into a powerful wizard. They start to have a mutual understanding, and Snape helps Harry with his studies and also with dealing with the trauma of his past.
One possible plotline could be Snape finding drunk Harry in the Hogwarts corridors. Snape, being the strict teacher, might initially be angry but then realizes Harry is in a vulnerable state. He could take Harry to his office to sober him up and in the process, they have a conversation that reveals some hidden feelings or understanding between them.
One possible plotline could be that Naruto is adopted by an Uchiha family early on. This changes his entire upbringing. He might be trained in the ways of the Uchiha from a young age, learning their unique fire - style jutsu and the secrets of the Sharingan much earlier. It could also lead to him having a different relationship with Sasuke, as they would be family in a sense. Maybe Naruto would be more in tune with the Uchiha's history and the tragedy that befell them, and this could fuel his determination to protect the village in a new way.
One possible plotline could be that Cloud, with its unique culture and way of life, would introduce Naruto to a whole new set of values. Naruto might struggle at first to adapt to the more reserved nature of the Cloud ninja. For example, he could have trouble fitting in with their strict training regimens that are different from what he's used to in Konoha. Another aspect could be his relationship with the other ninjas in Cloud. He might form an unexpected bond with a fellow outcast ninja, and together they could work towards changing some of the old - fashioned views in Cloud.
One possible plotline could be that Harry discovers Snape's true motives much earlier. Maybe he stumbles upon Snape's memories that show his complex relationship with Harry's mother. This new understanding makes Harry see Snape in a different light. They start to have secret meetings where Snape teaches Harry advanced magic, away from the prying eyes of others at Hogwarts. Their relationship gradually evolves from one of enmity to an unspoken bond.
One possible plotline could be that it's the result of some dark magic gone wrong. Maybe a spell was cast on Harry by an enemy of Snape's to embarrass him, and now they have to deal with the consequences together. Another could be that it's part of a prophecy that no one expected, and they must figure out how it fits into the wizarding world's future.
One possible plotline could be Harry being sold due to some dark magic plot against him. Snape then has to deal with this unexpected situation and protect Harry from further harm. Another could be that it's a part of a deal to save the wizarding world, and Snape and Harry must learn to work together in this strange new dynamic.
Another plotline could be that there is a spell or a magical occurrence that forces Snape and Harry to be close to each other. Initially resistant, Snape eventually gives in and cuddles Harry. This could then be the start of a journey where they learn to trust and rely on each other more.
Well, one possible plotline could be that Snape is examining Harry for some sort of magical ability or deficiency that he suspects. Maybe he's trying to figure out why Harry has such an affinity for certain spells. Another could be that Snape is examining Harry as part of a school investigation, perhaps related to some mischief that's been going on. And it could also be that Snape is secretly examining Harry to protect him from some hidden danger in the wizarding world.
One possible plotline could be Naruto growing up with a different set of values and training methods. Instead of the rough start he had in the original story, he'd be mentored by the Sarutobi clan's elders. He might learn more about the history and secrets of Konoha at an earlier age, which could lead to him being more politically aware and better equipped to handle future threats. For example, he could be trained in unique Sarutobi jutsu from a young age, giving him an edge in combat.
One possible plotline could be Naruto growing up with his uncle and learning different jutsu from him. His uncle might have a unique style of teaching that helps Naruto develop his skills faster. Maybe his uncle also has some secrets about Naruto's family that he gradually reveals as Naruto gets older.
