A possible plotline is that Naruto tries to hide the abuse from his friends and the village. He is afraid of being judged or rejected if they find out. However, as time goes on, the signs of abuse become more and more obvious. His friends start to suspect something is wrong and eventually, they discover the truth. This could lead to a series of events where Naruto's friends try to help him, and Naruto has to learn to trust them and accept their help to heal from the trauma of the abuse.
Another scenario might be physical abuse. His parents could be shown as using force against Naruto for minor mistakes. This would not only cause him physical pain but also make him fear his own parents. It could also lead to Naruto being more rebellious in some ways, as a form of self - defense mechanism.
One possible plotline could be Harry feeling extremely lost and alone at first. He might have to find a new place to live, perhaps with the help of his friends like Ron and Hermione. He could struggle with self - worth, constantly wondering what he did wrong to make his parents disown him.
One possible plotline could be that Naruto discovers a powerful jutsu that allows him to travel back in time. He then uses his knowledge of future events and his ninja skills to protect his parents from the attack that would otherwise kill them. For example, he might be able to stop the Nine - Tailed Fox from being unleashed on the village, thus saving his parents in the process.
A plotline might involve Naruto starting to act out in negative ways to get his parents' attention. He could start getting into trouble at school or in the village. Maybe he would start to explore his own powers in secret, away from his family, and discover some unique abilities that he then uses to show his parents what they've been missing. Also, there could be a plotline where Naruto tries to build a relationship with his sister in secret, hoping that through her, he can get closer to his parents.
One possible plotline could be that Minato and Kushina raise Naruto as a normal child in Konoha. Naruto would grow up with their love and guidance, which would significantly change his personality. He might be more confident from the start and not have that intense need to prove himself. Also, Minato could train Naruto personally, and Naruto might inherit his father's skills much earlier, leading to different adventures and battles in the ninja world.
In the fanfic, Naruto could die from an unexpected illness. His parents, who have been watching over him in spirit, are devastated. They might try to find a way to communicate with the living to tell them how special Naruto was. The mourning process could involve them seeing how the village comes together to remember Naruto, with his friends and comrades sharing stories of their adventures together. This would make his parents realize the kind of person Naruto had become and how much he meant to everyone.
One possible plotline could be that Naruto is banished due to false accusations of endangering the village, despite his parents being alive. His parents, Minato and Kushina, might be powerless to stop the decision because of some political intrigue within the village. Naruto then has to find his own way in the outside world, facing new enemies and making unexpected allies.
One possible plotline could be Harry initially being very distrustful of Voldemort, but as time goes on, he starts to see a different side of him. Voldemort, on the other hand, might be trying to use Harry for his own purposes at first but then develops a real bond. Another could be that Voldemort has to face the wizarding world's reaction to his newfound role as Harry's protector, which could lead to conflict. And Harry could grow to become a powerful ally to Voldemort in a new way, changing the power dynamics in the wizarding world.
It could also be due to a prophecy. Suppose there's a prophecy that Naruto will bring great disaster in the future. His parents, believing in the prophecy, might decide to disown him in an attempt to avoid that future. They might think that by cutting ties with him, they can somehow change the course of events.
A possible plotline could be that Naruto's mom and aunt discover some hidden power within Naruto that they need to help him control. They then train him in secret to master this power without the knowledge of the village at first.
