Well, one possibility is that Naruto would face some serious consequences. Killing is not in his usual nature, so he might struggle with guilt. Also, the Sound Village would likely seek revenge, which could lead to a full - scale war between Konoha and the Sound. Another thing could be that his friends in Konoha might view him differently, some might be afraid of his new - found brutality while others might try to understand his motives.
In the fanfic, if Naruto kills the Sound 4, it could make Sasuke more competitive. He might see Naruto as having achieved a level of ruthlessness that he himself desires. Or, Sasuke could be disappointed in Naruto for resorting to killing. Their relationship would be full of tension as Sasuke tries to figure out where he stands in relation to a Naruto who has killed, and Naruto might struggle with Sasuke's reaction to his actions.
No. Most Naruto fanfics tend to focus on positive relationships, growth of characters, and adventures within the Naruto universe. A plot where Sakura kills Naruto goes against the general themes of friendship and camaraderie that are central to the Naruto series, so it's not very common.
Yes, there might be. Fanfics cover a wide range of alternate scenarios. However, not all of them are easy to find. You can start by looking on popular fanfic websites like FanFiction.net or Archive of Our Own. But keep in mind that some fanfics may deviate significantly from the original Naruto storyline.
Yes, there are likely some fanfics out there with such a plot. Fanfiction is a creative space where authors explore different scenarios. However, it goes against the general narrative of the Naruto series where Naruto is more about saving Sasuke.
In a 'Naruto kills the Sandaime' fanfic, it would be a very dark and alternate take on the Naruto universe. This goes against the traditional bond and respect Naruto has for his village elders. It could be a result of some extreme corruption within the village that Naruto discovers, leading him to take such a drastic step. However, this is a huge deviation from the original storyline.
One consequence could be a shift in the power balance among the ninja villages. Since Orochimaru was a powerful and feared figure, his death might cause some chaos as his former allies or subordinates try to either avenge him or claim his resources. For example, some of his secret labs and experiments might be up for grabs, leading to potential conflicts.
I don't think 'naruto kills fanfic' is a widely popular type of Naruto fanfiction. While there are always fans who like to experiment with different ideas and darker plotlines, the overall Naruto fandom seems to be more centered around the positive aspects of the series such as Naruto's journey to become Hokage, his friendships, and his growth. However, there could be a small group of fans who are into this kind of more extreme or alternate - universe type of fanfiction.
If Naruto joined Sound in a fanfic, it would completely change the Naruto universe. His relationships would be flipped. Instead of being with Konoha friends like Sasuke and Sakura, he'd be among Sound ninjas. His training might take a different turn too, perhaps learning more brutal and underhanded techniques. This could also lead to a different set of battles and power dynamics in the story.
I'm not entirely sure specifically what a 'naruto kills fanfic' is. It could be a fan - made story where Naruto kills someone in a non - canonical or creative scenario. It might be a very specific plot within the Naruto fanfiction community that focuses on Naruto taking a life, perhaps in a dark or alternate universe story.
