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.
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.
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.
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.
The 'Menma Kills Naruto Fanfic' is likely a piece of fan - made literature that goes against the normal narrative of the Naruto series. Fanfics often explore what - if scenarios. In this case, perhaps the author was inspired by a different interpretation of Menma's character. Maybe in this fanfic, there are some underlying reasons for Menma to kill Naruto, such as being manipulated by a greater evil or having some deep - seated jealousy or grudge that is unique to this fictional version of the story.
Well, in a 'sakura kills naruto fanfic', it could be that the writer wants to explore a completely different side of Sakura's character. Perhaps in this fanfic's universe, Sakura has been corrupted or misinformed in some way that leads her to believe Naruto is a threat. It could also be a very edgy attempt at creating a shock - value story within the Naruto fan community.
On a broader scale, the ninja world would enter a new era. The threat that Madara posed would be eliminated, and Naruto would likely have a major role in shaping the new world order. He might focus on peace - building initiatives and forging stronger bonds between the different ninja villages.
