The original Naruto storyline would be distorted beyond recognition. Naruto's character, which is centered around his positive values like perseverance and kindness, would be warped. His relationships with other characters would become secondary. The story would lose its essence of being a coming - of - age tale about a ninja. Instead, it would become a story full of moral and ethical dilemmas centered around this inappropriate relationship. His interactions with the village elders, his training, and his overall place in the ninja world would all be re - written to accommodate this strange new plotline.
This event in the fanfiction would impact his relationships. His friends would be devastated, and it would change how the village of Konoha views his legacy. Instead of a hero who overcame all odds, he would be remembered as a victim of a sudden accident. Also, it could lead to different power dynamics in the village as his absence would create a void that others would have to fill.
It challenges the original storyline mainly by going against the expected relationships. In the original, their relationship was more of a rivalry. So, having them fall in love completely changes the dynamic. It also challenges the way the characters were initially portrayed in terms of their sexual orientations and their loyalty to their own groups.
It changes the Naruto universe by introducing a new dynamic. Usually, Kaguya was seen as an ultimate villain. But if she falls in love with Naruto, it turns the whole concept of good and evil on its head. It could lead to a more united ninja world as they have to accept Kaguya in a new light. Also, Naruto's influence on Kaguya might change how she uses her powers. Instead of being a source of destruction, her powers could be used for the betterment of the ninja world.
If in fanfiction Naruto had a child with his sister, it would be a radical departure from the original Naruto storyline. In the original, Naruto's focus is on becoming Hokage, protecting the village, and his relationships with his comrades. This new scenario would introduce a moral and ethical dilemma that the original story never had. His relationship with his sensei, like Jiraiya, and his peers would become very strained. His family, which has always been presented in a positive light, would now be associated with something very wrong. It would also change how the fans perceive Naruto, as he is now involved in an unacceptable relationship that goes against the very essence of the character and the world he lives in.
No, it's not ethical. Naruto is a story that is aimed at a wide audience, including young viewers. Incestuous themes are not only against the values of the Naruto world but also inappropriate for the target audience. The ninja clans in Naruto have their own traditions and rules, and this kind of relationship would be a violation of all of them.
In the original Naruto story, family relationships are based on love, protection, and a sense of kinship that is not romantic. Naruto has a strong bond with his family members, like his father and mother in a non - romantic way. Having him in love with his sister completely changes the nature of family relationships that the original story portrays. It's a huge deviation as the original focuses on Naruto's growth as a ninja, his friendships, and his quest to be recognized in the village.
In some fanfictions, Naruto might show his love for his sister by protecting her at all costs. For example, he would stand in front of any danger that comes her way, just like how he protects his friends in the original story.
The story would deviate from the original themes of unity and friendship. Naruto's hatred could split Konoha into factions. This would mean different training regimens, different missions, and different loyalties. For example, Naruto might start his own group of ninjas who share his views, which would completely change the power dynamics in the village.
In the original, Naruto's team supports him and they grow together. However, in this fanfiction, the concept of Naruto hating his team means that all those positive interactions and character developments are thrown out. His relationships with his teammates, which were based on mutual respect and trust in the original, are now replaced with negative feelings.
Well, it changes the romantic aspect completely. Instead of the love triangle with Edward and Jacob, it focuses on Bella's relationships with female characters. This alters the whole dynamic of the story. For example, her interactions with her family and friends would be different as they react to her new - found sexual orientation.
