In this fanfiction, Naruto and Madara could engage in friendly battles to test each other's strength. These battles wouldn't be about hatred or revenge but rather about mutual growth. Naruto could learn new techniques from Madara, and Madara could be impressed by Naruto's ability to quickly adapt and improve. Their friendship could be based on respect for each other's power and determination.
One possible plot could be that Naruto, with his unwavering belief in redemption, tries to understand Madara's past grievances. He might start by finding common ground in their love for the Hidden Leaf, despite Madara's later turn against it. Naruto could use his talk - no - jutsu to gradually break down Madara's walls of hatred. They could then team up to face a new, greater threat that endangers the entire ninja world. This new threat would force them to combine their skills, Naruto's Rasengan and Madara's Susanoo for example, in unique ways to protect what they both once held dear.
The Hidden Leaf Village would surely launch a rescue mission. They would send their best ninjas, like Sasuke, Kakashi, etc. This could lead to intense battles between Madara's forces and the Leaf Village ninjas. It would be a great opportunity to show off different ninja techniques and strategies.
In such a fanfiction, Naruto might initially try to persuade Madara to give up his evil plans. He could use his talk - no - jutsu to appeal to Madara's better nature, if there is any left. Maybe they would have an epic battle first, with Naruto showing off his new Sage of Six Paths powers against Madara's Rinnegan abilities.
One possibility is that Naruto would gain a different perspective on the shinobi world. Madara has his own views which are often very different from the traditional ones. This could lead Naruto to question some of the things he has been taught and make him more open - minded in dealing with future conflicts, not just thinking in the way of Konoha but on a broader scale of the whole shinobi world.
If Naruto were to become like Madara in fanfiction, it would be a huge shift. Naruto has always been about hope and friendship. But like Madara, he could start to see the ninja world as something that needs to be reshaped by his own hands, regardless of the cost. He may abandon his village's values and try to impose his own version of order. This would lead to conflicts with his former allies. For example, Sasuke might be one of the first to oppose him as Sasuke has his own ideas about the ninja world and would not easily accept Naruto's new Madara - like ways.
One possibility is that Naruto would use Madara's powerful body to end conflicts in the ninja world more quickly. With Madara's physical strength and Naruto's spirit, he could overpower enemies easily.
There could be a backstory where Madara and Tobirama had a secret agreement that led to Naruto's existence. Maybe they foresaw a future threat and planned for Naruto to be born with their combined power to save the ninja world. Naruto would then have to uncover this mystery and fulfill his destiny.
In a fanfiction where Naruto and Madara are friends, it could completely change the Naruto storyline. Their friendship might start from a mutual understanding of their strong wills. Naruto, with his belief in redemption, could see past Madara's actions. And Madara, who has been alone for so long, might be drawn to Naruto's positive energy.
One possible thing that could happen is Naruto would gain new visual abilities. With the Sharingan, he might be able to copy jutsus even more effectively than before. The Sharingan could also potentially enhance his perception of his opponents' moves, making him an even more formidable fighter in battle. This could change the power dynamics in the Naruto universe significantly.
Well, Naruto's positive attitude would likely have a huge impact on Madara. He might be able to stop Madara from becoming so bitter. Madara might end up being more like Naruto, believing in the goodness of people.
