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 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.
One possible consequence could be chaos. Naruto was often seen as a symbol of hope and peace. His death at the hands of Madara would likely shatter the dreams of many characters. The villages might descend into fear and distrust again, and there could be a power vacuum that leads to wars between the different ninja villages.
If Naruto kills Madara in fanfiction, it could completely shift the power dynamics in the Naruto universe. For one, it might lead to a more peaceful era much sooner as Madara was a major source of conflict. The Akatsuki's plans would likely fall apart without his influence, and the shinobi villages might start to focus more on internal rebuilding and cooperation rather than external threats.
Naruto is often paired with Madara in some fanfictions. Their interactions can be really intense, as Naruto tries to either convince Madara to change his ways or fight against his reborn form.
When Madara travels through time, he might find allies in unexpected places. For instance, some of the minor ninja clans that were oppressed by the larger clans in the past could see Madara as a liberator if he offers them a better future. On the other hand, those who benefit from the current ninja world order, such as the Daimyo or certain powerful shinobi from other villages, might see Madara as a threat and become his enemies.
Often, Naruto might be paired with Madara in some sense. Their opposing views on power and peace could create interesting interactions in the fanfiction.
Sasuke could be a main character as well. Given his own experiences of being an outcast and having a thirst for power at times, he could relate to Madara in some ways. They might form an unexpected alliance or have a rivalry based on their shared experiences of feeling neglected or misunderstood in the ninja world.
