Often, there is a plot twist where Naruto finds out he has a special power or heritage that was the reason for his family's neglect. In the context of the harem, this new discovery makes him more desirable to the harem members. It also adds a layer of mystery and conflict as Naruto has to deal with this new - found identity while also navigating his relationships in the harem. And he may have to face enemies who are after his new power or heritage.
A plot twist could be that Naruto discovers that his family's neglect was actually part of a bigger scheme. In the harem fanfiction world, perhaps someone was manipulating his family to keep Naruto down so that they could have an advantage in the competition for Naruto's affection in the harem. This revelation would completely change Naruto's view of his family and the situation he's in.
Well, a typical plot twist is that Naruto leaves the village due to the neglect. He then returns as a much stronger and more mysterious figure. This forces his family to re - evaluate their actions. Another common plot twist is that the sister is actually in danger, and Naruto is the only one who can save her, despite the family's past treatment. It flips the situation and shows that Naruto is still the bigger person. And sometimes, a plot twist could be that Naruto has a secret heritage that was the real reason for the family's strange behavior towards him.
One common plot twist is that Naruto discovers his friends' neglect was due to some sort of misunderstanding or external manipulation. For example, a villain might have been using genjutsu on his friends to make them act that way. Another twist could be that Naruto, after being neglected, actually becomes more powerful in secret and then surprises his friends when he reveals his new strength. It makes them realize what they've been missing out on.
One common theme is isolation. Naruto feels alone due to his family's neglect, which pushes him towards evil. Another is revenge. He may seek to get back at those who ignored him or his family. Power - hunger is also often seen as he tries to gain strength to prove himself, since his family didn't give him the love and support he needed.
One common theme is self - discovery. Naruto, being neglected by his family, has to figure out who he is on his own. Another theme is the search for belonging. Since he doesn't have a family to belong to, he looks for that sense of place elsewhere, like among his friends or in the village as a whole. And there's also the theme of resilience. Despite the neglect, he has to be strong and keep going.
Common themes often include a sense of longing. Naruto would long for the family love and support he doesn't have. There's also the theme of power mismanagement. As a god, his emotional state due to neglect might cause him to either misuse his power or struggle to control it. And the theme of finding a new family or a sense of belonging outside of his biological family is also quite common in these fanfictions.
One possible plot twist could be that her family has a secret reason for neglecting her. Maybe they're trying to protect her from some greater danger. Another could be that she discovers she has a hidden power that makes her family regret their neglect.
Some fanfictions might have a plot twist where Naruto's family is alive but has lost their memories. So Naruto has to help them regain their memories while also dealing with the fact that they are his family. Another common twist is that his family has been living in another dimension all this time. And when Naruto finds out they're alive, he has to find a way to bring them back to his world. There could also be a twist where his family was actually kidnapped and held captive by an enemy, and Naruto has to rescue them.
Perhaps the Akatsuki's neglect is a part of a much larger plan by Naruto himself. He might be trying to lull the Akatsuki into a false sense of security while he's actually gathering information or power in the background. Then, when the Akatsuki least expects it, Naruto reveals his true intentions and uses the situation to his advantage, which would be a huge plot twist for the readers who thought Naruto was just being mean or indifferent.
One plot twist could be that Naruto discovers his parents had a very good reason for their neglect, like they were protecting him from a greater danger. Another could be that the village elders knew about the neglect but did nothing, and Naruto has to confront them. Or perhaps Naruto finds out he has a secret power that was the cause of his parents' seeming neglect, as they were afraid of what he could do.
A plot twist might be that Naruto's family abandonment was part of a prophecy. In the fanfiction, it could be that in order for Naruto to fulfill a certain destiny, he had to be abandoned so that he could grow in a specific way. Also, there could be a plot twist where the person Naruto thought was his enemy all along was actually the one who knew the truth about his family and was trying to guide him back to them in a roundabout way.
