In this fanfiction, their relationship could also turn into a sort of partnership. Naruto's strength could be used to convince Madara to use his knowledge and power for the greater good. They could work together to face new threats that neither of them could handle alone, with Naruto taking the lead due to his greater strength.
There could be a shift from enmity to a begrudging respect. Madara has always been a powerful and feared foe, but with Naruto being stronger, Madara may have to accept Naruto's superiority. Naruto, on the other hand, would likely try to understand Madara's motives better and might try to reform him rather than just defeat him.
Well, it depends on the specific fanfiction. There are various interpretations out there. Some fanfictions focus on Naruto's growth after the original series and give him abilities like super - charged chakra control or the ability to nullify Madara's strongest jutsu. However, in the original canon, Madara is an extremely powerful opponent. But in fanfiction, the rules can be bent to make Naruto stronger.
Well, it depends on the specific fanfic. Some fanfictions might give Naruto an edge over Madara by, say, having him master some super - secret jutsu that completely nullifies Madara's powers. Or they could boost Naruto's physical and chakra capabilities to an extent where he can easily defeat Madara. However, in the original Naruto lore, Madara is an extremely powerful foe, but fanfic authors have the freedom to change the power balance as they see fit.
Well, in such a fanfiction, it might start with Naruto being in a situation where he becomes Madara's pet. Maybe at first, Naruto is defiant but as time passes, he could start to understand Madara's motives in some strange way. Madara, on the other hand, might initially see Naruto as just a possession but gradually develop a sense of attachment. It could be a really strange and complex relationship that unfolds as the story progresses.
By getting new powers like some ancient and forgotten jutsu.
In fanfiction, Naruto can be stronger than Madara for multiple reasons. Some authors might want to subvert the expectations set by the original story. They could give Naruto unique abilities like the ability to manipulate time, which would clearly put him above Madara in terms of power. Additionally, it could be a way to bring in crossovers. For instance, if Naruto gains powers from another fictional universe, he could easily be made stronger than Madara. Moreover, the author may simply want to explore a scenario where Naruto is the most powerful character, and making him stronger than Madara is a step towards that.
Well, in such a fanfiction, Madara's training might enhance Naruto's physical strength. He could teach Naruto some advanced Uchiha techniques which Naruto can combine with his own Uzumaki powers. For example, Naruto might learn better chakra control from Madara, enabling him to use his Rasengan more effectively and with less chakra waste.
One possible reason could be that Naruto has developed some new and extremely powerful jutsu in the fanfiction. Maybe he has found a way to combine his Sage Mode with his Kurama chakra in an even more efficient and powerful way that gives him an edge over Madara.
Another way is through a prophecy. In the fanfiction, there could be a prophecy that only Naruto and female Madara together can save the shinobi world from a great disaster. At first, they don't believe it, but as the signs of the disaster start to appear, they are forced to work together. As they spend time together trying to prevent the disaster, they learn about each other's pasts, hopes, and dreams, which leads to a deep emotional connection.
Naruto could use his shadow clones. He might create a bunch of clones to distract Madara while he finds a way to break free from whatever is binding him. Since Madara is a powerful opponent, Naruto would need to be very strategic with his clone usage.
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.
