In fanfiction, one way to combine EMS (Eternal Mangekyou Sharingan) and Rinnegan powers could be through a powerful jutsu. For example, a character might create a new form of ninjutsu that draws on the unique abilities of both. The EMS could provide enhanced visual perception and the ability to cast powerful genjutsu, while the Rinnegan could offer control over different elements and the six paths techniques. They could be combined in a way that allows for teleportation between different dimensions, using the space - time manipulation aspects of both powers.
One great fanfiction idea could be about a character who has both the Rinnegan and Sharingan and uses them to travel through different dimensions in the Naruto universe. They could encounter ancient and powerful beings, and learn new jutsu that combine the unique abilities of both eyes.
One interesting fanfiction idea could be a story where a new character is born with a combination of all three powers. This character would face many challenges as the ninja world would either fear or try to use this unique being for their own gain.
The balance can also be achieved by making the OC need to train and develop their Rinnegan powers gradually. They start with basic abilities and as the story progresses, they learn more complex and powerful ones. This way, they face challenges appropriate to their current power level at each stage of the story, and the power growth feels more natural and not overly sudden.
Maybe the red hair is a result of a genetic experiment or a curse that is linked to the Rinnegan. In the fanfic, it could be explained that an ancient ninja tried to combine the power of the Rinnegan with a powerful fire - type jutsu. The experiment went wrong in a way that gave the character red hair and also altered the Rinnegan's abilities. For example, the Rinnegan might be able to absorb and redirect fire - based attacks more effectively because of this connection.
Their powers could combine in combat. Naruto's Rinnegan - based abilities like the ability to absorb or deflect attacks could be used to protect Yugito while she unleashes her Jinchuriki powers. For example, if she goes into her partial - tailed beast form, Naruto can use his Rinnegan to shield her from incoming attacks that she might not be able to dodge in that form.
A character like Arya Stark might initially be very cautious. Given her training as a Faceless Man, she would be skeptical of new powers. But she could also see the potential for using the Rinnegan's powers for her own vengeance. She might try to use the power of seeing chakra points to target her enemies more effectively.
The Rinnegan's basic powers like enhanced perception could give a Young Justice character an edge in combat. For example, they could see an enemy's attack coming from a mile away. The Six Paths powers might be adjusted to fit the Young Justice setting. Maybe the Deva Path power could be used to manipulate gravity in a more superhero - like way, like creating anti - gravity fields to lift heavy objects or send enemies flying.
Well, one way could be using the Byakugan's detailed vision to enhance the Sharingan's ability to predict an opponent's moves. For example, the Byakugan can see the chakra flow in the body, and the Sharingan can then use this information to more accurately anticipate what the opponent will do next. Then, the Rinnegan could be used to manipulate the environment based on this knowledge. So, like if an opponent is about to attack from a certain direction, the character could use the Rinnegan to create a barrier or change the terrain in that area.
Dark Naruto with the Rinnegan would have access to powers that are more in line with the Sage of the Six Paths' legacy. His perception of the world would be different. While regular Naruto sees the world in a more straightforward way, Dark Naruto could use the Rinnegan to see chakra flows in a more detailed manner, allowing him to predict his opponents' moves better. Also, the Rinnegan - powered Dark Naruto could potentially use the Animal Path to summon creatures that are more powerful and dangerous than the normal summons. His power would be more about manipulation and control rather than the brute force that regular Naruto sometimes uses.
