One plot implication could be that Naruto becomes a target for more powerful enemies. Since the Rinnegan is such a powerful and coveted dojutsu, many villains might want to either steal it from him or kill him to prevent him from using it. Another aspect could be that Naruto has to learn to control the Rinnegan's powers, which could lead to some internal struggles as he tries to balance his existing powers with this new and extremely potent ability.
It would change his abilities in multiple ways. Firstly, with the Rinnegan, Naruto could have better perception of the world around him, similar to how Nagato was able to sense things from afar. Secondly, he might be able to use the Animal Path to summon powerful creatures. This would give him more options in battle. Also, the Rinnegan could potentially allow Naruto to access some form of chakra absorption or manipulation that he didn't have before, further diversifying his power set.
Well, one possibility is that Naruto gains new powers with the Rinnegan. He might use it to finally bring true peace to the ninja world. Maybe he could combine the power of the Rinnegan with his existing Sage Mode and Nine - Tails chakra, becoming an even more formidable force against any threats.
The story would change drastically. Naruto's combat abilities would be enhanced. He could use the Rinnegan's powers like the Six Paths techniques, which would give him an edge in battles. For example, he could use the Preta Path to absorb chakra attacks from opponents.
One possibility is that there was some sort of spiritual or chakra - based connection between Naruto and Nagato. Nagato, being the possessor of the Rinnegan, recognized Naruto's strong will and the fact that he was on a path to change the ninja world for the better. Through this connection, Nagato was able to transfer the power of the Rinnegan to Naruto. It could also be related to the nature of the Sage of Six Paths' power that was somehow involved in this transfer, as both Naruto and Nagato were related to the Sage in different ways.
In some fanfiction concepts, there could be a spiritual or mental connection established between Naruto and Nagato. Since Naruto has this unique ability to understand and connect with people on a deep level. Through this connection, Nagato might pass on the power of the Rinnegan to Naruto. It could be like a transfer of not just the physical power but also the knowledge and understanding that comes with the Rinnegan.
When Naruto gets the Rinnegan from Nagato in fanfiction, it can completely transform his role in the story. He not only gains new combat capabilities but also a new level of understanding of the ninja world. The Rinnegan might give him insights into the origin of ninjutsu or the true nature of the tailed beasts. This could lead him on a new quest to uncover secrets related to the Rinnegan and use that knowledge to reshape the ninja world. Moreover, it could also change how other villages view him. Some might see him as a potential dictator with such great power, while others might see him as the ultimate savior.
In some fanfictions, Naruto might get the Rinnegan from Nagato through a transfer of power. This could be due to Nagato seeing Naruto as a worthy successor and using some sort of jutsu to pass on the Rinnegan's power before he dies. Another possibility is that there is some sort of magical or spiritual connection between them that enables the transfer.
Well, it could mean that Naruto's view of the world and his relationships with others would change. The Rinnegan comes with a lot of knowledge and a different perspective. He might see the ninja world in a more complex way. Also, it could affect his relationships with his friends and allies. Some might be in awe of his new power, while others might be a bit wary. And in terms of the story, it could open up new plotlines, like exploring the full potential of the Rinnegan in Naruto's hands and how he uses it to face new and old enemies.
One major implication is that Naruto's power level would skyrocket. The Rinnegan is an extremely powerful dojutsu, so he would be able to use a whole new set of abilities. For example, he could use the Six Paths techniques more effectively than before.
