In Naruto vs Gaara fanfiction, one aspect could be the exploration of their different powers. Naruto has his Nine - Tails chakra while Gaara has his sand control. Fanfictions might depict intense battles where Naruto's speed and strength are pitted against Gaara's impenetrable sand defenses. Also, the emotional depth of their characters can be delved into. Naruto, with his goal to be recognized, and Gaara, who once felt alone and feared, could have deep conversations or internal monologues in these fan - made stories that add more layers to their relationship beyond just the fight.
Sasuke is often a popular character in these fanfictions. He might play a role in helping Naruto against Madara or have his own motives during their battle. Kakashi can also be a prominent figure, perhaps using his Sharingan in a crucial moment to assist Naruto. Another popular character could be Hashirama, as his connection to Madara is a key part of the original story and can be further explored in fanfiction.
Another theme is redemption. Sometimes in these fanfics, Madara has a chance at redemption through his fight with Naruto. Naruto's belief in people's goodness can influence the outcome in such scenarios.
The most prevalent themes are probably rivalry and respect. Their initial fight was based on rivalry, but as the story progresses in fanfiction, they start to respect each other's strength. There's also the theme of growth. Both characters grow not only in power but also in their mental and emotional states. And sometimes, there's a theme of sacrifice. One might be willing to sacrifice something for the other's well - being, which is an interesting twist on their relationship in fan - created stories.
Naruto would probably win. He has an indomitable will and has always found ways to overcome powerful foes. His experience and the unique powers he might gain with the Rinnegan could give him an edge over Madara.
One interesting plotline could be Naruto discovers a new form that gives him an edge over Madara. For example, a form that allows him to nullify Madara's Sharingan abilities. Another could be Madara having a change of heart due to Naruto's unwavering belief in him. Maybe he starts to question his own motives for destruction.
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.
