One possibility is that Naruto and Madara meet in a different dimension or time. For example, if Naruto somehow travels back in time, he could meet a younger Madara. Naruto, with his knowledge of the future, might try to prevent Madara from going down the dark path. He could introduce Madara to new ideas about coexistence among the ninja clans, which could rewrite the entire history of the ninja world in this fan - made scenario.
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.
If Naruto meets Hashirama and Madara in fanfiction, Naruto could learn a great deal from Hashirama about building and uniting a village. Hashirama was the founder, after all. With Madara, Naruto might face some challenges as Madara had a very different view of the ninja world. However, Naruto's ability to befriend and understand his enemies could lead to an interesting turn of events. Maybe Naruto could even find a way to reconcile the two long - dead legends.
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 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.
Well, Sarada might be in complete awe when she first meets Madara. She could try to learn some of his powerful jutsu techniques. Maybe she would also question him about the history of the Uchiha clan that she has only heard stories about.
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.
Well, it could be that Naruto meets the Hokage in a different time - space. They might work together to change some important events in the history of the village. For example, preventing a great disaster or changing the fate of some important characters. And Naruto could learn a great deal from the Hokage's wisdom and leadership in this encounter.
Well, in such a fanfiction, Naruto might learn new jutsus from Fuu. Maybe they go on an adventure together to find a rare item or to save a village.
