Yes, there might be such a fanfiction. In the Naruto fandom, with its large and diverse range of fan - created works, various out - of - canon scenarios are explored. However, this goes against the original storyline where Hinata and Neji have a complex relationship that is more about growth, understanding, and family bonds rather than such a violent act.
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.
In the Naruto universe, Naruto killing Neji would be a very dark and out - of - character turn. However, in fanfiction, it could be due to some dark influence like a powerful and evil genjutsu that overpowers Naruto's mind and makes him see Neji as an enemy. Maybe a villain has managed to manipulate Naruto's perception of reality to make him commit such an act.
On a larger scale, the balance of power in the ninja world could be affected. Neji was a strong and capable shinobi, and his absence could create opportunities for enemies to take advantage. Naruto's actions could also damage the reputation of Konoha as a whole. Other villages might view Konoha as unstable or dangerous if one of their most well - known shinobi can turn on his own comrades. This could lead to increased tensions and potential conflicts between the different ninja villages.
One possible motive could be a dark or alternate universe take. Maybe in this fanfic's world, there is some sort of dark magic or mind control that forces Naruto to do it against his will.
One possible plot could be that Hinata is somehow mind - controlled. Maybe an enemy uses a powerful genjutsu on her that makes her see Neji as a threat to Naruto or to the village. Under this influence, she attacks and kills Neji, which then leads to a great deal of guilt and self - loathing for Hinata once she breaks free from the control.
In this 'madara kills naruto fanfiction', the scenario might be set up in a way that the world around them has changed. Maybe there are new rules in the ninja world that Madara has adapted to better than Naruto. He could be using the political or social situation to his advantage. Additionally, the writer may have given Madara a different motivation that makes him more ruthless and determined to kill Naruto, and through a series of carefully crafted events, he manages to achieve this goal.
One of the most dramatic scenes could be the final face - off between Naruto and Madara. Naruto, filled with resolve, might use a new and powerful jutsu that catches Madara off - guard. The moment when Naruto's attack lands on Madara, with a big explosion and a flash of light, would be very dramatic.
One possibility is that Naruto discovers a new power or form that gives him an edge. For example, he might combine Sage Mode with a new type of chakra control that allows him to overpower Madara.
It's a very controversial plot. Neji is an important character in Naruto, and his relationship with Naruto is complex but not one of enmity to that extreme. In the original story, they are comrades. So a fanfic with such a plot goes against the general spirit of the Naruto world and would shock many fans.
