In this fanfiction scenario, there would be far - reaching consequences. Naruto's death at the hands of his mother would shatter the very foundation of the relationships in the Naruto universe. The Nine - Tailed Fox's power would be unaccounted for, which could lead to all sorts of problems. His friends would not only have to deal with the loss but also the fact that it was his mother who did it. This could lead to a moral crisis in the village. Additionally, the balance of power between the villages would be disrupted as Naruto was a key figure in maintaining peace. It could even lead to a full - scale war if other villages saw Konoha as vulnerable.
The most obvious consequence would be the extreme grief among Naruto's friends like Sasuke, Sakura, and Kakashi. They would be devastated and likely seek revenge. The village would also be in chaos as Naruto was seen as a hero - in - the - making. It would completely change the future of the village.
If Naruto were killed by Kushina in fanfiction, the entire shinobi world would be affected. Konoha would lose its hope for a peaceful future. The other villages might take advantage of Konoha's weakened state. His friends would probably go through a lot of emotional turmoil. Sasuke, for example, who had a deep bond with Naruto, might turn even more bitter and vengeful. And Sakura, who also cared deeply for Naruto, would be heartbroken. It could also lead to a split in the village as some might blame Kushina and others might try to understand the situation.
One major consequence would be in terms of his abilities. Kushina was known for her powerful sealing techniques. So if Naruto becomes her, he might lose some of his unique Naruto - like skills and instead gain more proficiency in sealing. This could change the way he battles. For example, he might rely more on sealing away enemies rather than his usual Rasengan and Shadow Clone techniques. And his role in the village as a protector might also change as he adapts to Kushina's abilities.
The most immediate consequence would be the reaction from Naruto's friends. Sasuke, for example, would likely go on a quest for revenge. He has a deep bond with Naruto and would not let his death go unpunished. Sakura would also be devastated and might lose faith in the idea of peace between the villages.
Well, for one, Hinata would be completely devastated. She loved Naruto deeply. Her world would crumble. Shikamaru, who respected Naruto's determination, would be angry and confused. Why would Kushina do such a thing? The other Konoha 11 members would also be in a state of disbelief. They had all fought alongside Naruto. Iruka, Naruto's first teacher, would be inconsolable. He had always believed in Naruto and watched him grow. And Jiraiya, if he were still alive in this fanfiction, would be filled with regret for not teaching Naruto more to avoid such a fate.
Naruto would likely be deeply hurt, not just physically but also emotionally. He has always idolized his mother, so an attack from her would be a huge blow to his psyche. His trust in family and those close to him could be severely damaged.
One consequence could be a shift in Naruto's character development. Having his mother back might make him more at ease and less driven by his past loneliness. It could also change his relationship with other characters. For example, his bond with his father figure, like Iruka or Jiraiya, might not be as strong as it was when he was motherless. Another consequence could be in the political aspect of the ninja world. Kushina was an Uzumaki, and her return could strengthen the Uzumaki clan's position and influence, which might cause some unrest among other clans who fear the growing power of the Uzumakis.
One consequence could be Naruto's emotional breakdown. Since Kushina is his mother, her betrayal would be a huge blow to him psychologically. He might start to doubt himself and his place in the world.
One consequence could be that fans who really respect Kushina's character might be more hesitant to engage with fanfictions. If they know that Kushina, in a sense, wouldn't approve, they might feel guilty or less interested in exploring those fictional works.
The village of Konoha would also be affected. With Minato still alive, he could continue to lead the village and make different decisions. This might change the relationships between Konoha and other villages. For example, there could be more peaceful alliances as Minato is known for his diplomatic skills. Also, Kushina being alive would mean that the Uzumaki clan might have a stronger presence in the village, which could lead to new jutsu developments and a different power balance within Konoha.
One consequence could be that Naruto becomes an outcast in a different way. In the original, he was an outcast because of the Nine - Tails, but here, it could be because of his abandonment. He might not have the same dreams of becoming Hokage. Instead, he could be more focused on survival.
On a more personal level, they could face internal guilt. As Naruto grows up and achieves great things on his own despite their neglect, Minato and Kushina may realize what they've missed out on. This realization could cause them a great deal of internal turmoil and regret for not being there for their son when he needed them.
