Well, one possible outcome could be that Naruto and Sasuke manage to defeat Madara through their combined strength and newfound powers. They might use their signature jutsus in a coordinated way that Madara can't counter.
In such a fanfiction, Naruto and Sasuke might win. They are both extremely powerful and their combined strength, like Naruto's Rasengan and Sasuke's Chidori, could overpower Madara.
The fanfic 'Naruto and Sasuke: The Unspoken Understanding' is also quite good. It focuses on the unspoken communication between Naruto and Sasuke. It has a unique take on how they support each other during difficult times in the ninja world, and the character development is really well - done.
A great 'naruto e sasuke fanfic' often has a strong focus on their relationship. It should show their growth as individuals and as a duo. For example, exploring their past traumas and how they help each other heal. Good characterisation is key.
Power and growth are also common themes. Fanfics might show Sasuke and Naruto achieving new levels of power and how they use it. For example, they could be unlocking new jutsu or developing new skills. Also, the theme of sacrifice often comes up. They might have to sacrifice something, like their personal desires or safety, for the greater good of their village or each other. This is in line with their selfless nature in the original story.
Sasuke could also be the one. With his Sharingan and Rinnegan, he has unique abilities. He might use his Amaterasu in a very unexpected way, like creating a large - scale trap for Madara using the black flames. His intelligence and cold - blooded nature in battle make him capable of making a decisive move.
In such a fanfiction, the story could take a very dark turn. Naruto's ideals of friendship and peace might be severely tested. He could be forced to question his own beliefs as Obito and Madara have very different outlooks. Maybe Naruto would try to change their minds, but it would be extremely difficult as they are both very set in their ways of achieving a new world order through more extreme means.
