The most interesting part could be the exploration of Naruto's new limits. The Rinnegan brings a whole new set of abilities that Naruto has never had before. He could learn to use the Animal Path to summon powerful and unique creatures. This would not only change his combat capabilities but also his role in the ninja world. Also, how would the hidden villages react to Naruto having such a powerful dojutsu? Some might fear his new power, while others might see him as an even greater protector. This political aspect would add depth to the fanfiction.
One interesting aspect would be seeing Naruto combine his existing jutsu with Rinnegan abilities. For instance, mixing his Rasengan with the power of the Rinnegan's Six Paths could create an entirely new and devastating attack. Another aspect is how it would affect his relationship with Sasuke. Sasuke has the Sharingan and later the Rinnegan in the original story. With Naruto also having the Rinnegan, their dynamic would change, perhaps leading to new rivalries or alliances based on their shared power.
Well, first of all, Naruto with the Rinnegan would be a total game - changer. In the story, the Rinnegan has always been associated with great power and mystery. If Naruto got it implanted, he could potentially use the Deva Path to manipulate gravity, which would be a huge advantage in combat. His enemies would have to completely re - evaluate their strategies against him. And on a more character - development level, he might struggle with the new power, as it comes from an external source and not his own natural growth. This internal conflict could add a whole new layer to his character arc.
It could be interesting to see Naruto with both EMS and Rinnegan in fanfiction. Naruto is known for his Uzumaki vitality and his ability to master new powers quickly. Having EMS and Rinnegan would give him an entirely different set of skills. He could combine the Rasengan with Rinnegan - based techniques and use the EMS - enhanced perception to dodge attacks even better. His positive attitude and never - give - up spirit would make for an exciting exploration of these powers.
One interesting aspect could be his new powers. Norse demigods have powers like superhuman strength and the ability to control certain elements. Naruto could combine his chakra control with these new powers. For example, he might be able to use his Rasengan in a new way that is influenced by his demigod powers.
One interesting aspect could be the unique interpretations of the Rinnegan's powers. In fanfics, the author might explore new ways the perfect Rinnegan can be used in battles, like combining different jutsu in unexpected ways. For example, it could be used to manipulate time and space simultaneously, which is not seen in the original Naruto series. This adds a new layer of excitement and unpredictability to the story.
Another cool concept is the idea of a character with the Rinnegan being a biotic anomaly. Since biotics in Mass Effect are about manipulating dark energy fields, the Rinnegan's power to manipulate chakra could be seen as a parallel, and fanfictions might explore how this would change the perception and use of biotics in the Mass Effect universe. This could involve things like new biotic techniques or the character being hunted or revered for their unique abilities.
There are some great plotlines in rinnegan naruto fanfics. For example, in 'Naruto's Rinnegan Awakening', the plot is centered around how Naruto awakens the rinnegan and how it changes his relationships with his friends and enemies. Some of his friends are scared of his new power, while some enemies see him as an even greater threat. In 'The Rinnegan and Naruto's True Purpose', the story is about Naruto realizing that his rinnegan gives him a new purpose in life, not just to protect the village but to unite all the shinobi clans. And in 'Rinnegan Naruto: Beyond the Limits', the plot follows Naruto as he pushes the limits of his rinnegan powers, going beyond what anyone thought was possible and facing the consequences of his actions.
One interesting plot point could be how Naruto's relationships with his friends change. With the Rinnegan, he might seem more distant or different to them at first. But as he grows and learns to control it, they could come to rely on his new powers. Another point is how the ninja villages react to Naruto having the Rinnegan. Some might fear him, while others might try to recruit him. And of course, there's the mystery of how he got the Rinnegan in the first place.
Sasuke would be an interesting character to cross over. He has the Rinnegan and a complex backstory. In the Inuyasha universe, his brooding nature and his powerful abilities would create a lot of interesting interactions. He could have a sort of rivalry with Inuyasha, as both are strong - willed and have a lot of power at their disposal. And his journey of redemption in Naruto could translate into a different kind of character arc in the Inuyasha world, perhaps learning to work with the half - demon Inuyasha despite their differences.
In this type of fanfiction, a really cool aspect could be the evolution of Naruto's appearance. If he has implanted DNA, he might start to take on physical traits from the source of that DNA. His eyes could change color, or he could grow new markings on his body. This not only makes him look different but also might be a sign of his new power level to his friends and foes alike. It can add a whole new layer of intrigue to the story as people try to figure out what's happened to him.
One interesting plot twist could be if the alchemical principles in Fullmetal Alchemist were somehow applied to the use of the Rinnegan in Naruto. For example, the Rinnegan's powers being transmuted or enhanced in a way not seen in the original Naruto series.
