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 Dead Bone Pulse could provide a physical advantage that complements the Sharingan. When using the Sharingan in combat, the user might be vulnerable to close - range attacks. But with the Dead Bone Pulse, they can quickly create bone armor or weapons for self - defense. Also, the bones could be used to set traps that are easier to plan with the Sharingan's predictive abilities.
Well, normal Naruto mainly relies on his chakra and the Nine - Tails' power. But Dark Naruto with Eternal Mangekyou Sharingan would have unique visual jutsu. He could use the Sharingan's genjutsu abilities on a much greater scale, perhaps even trapping entire villages in an illusion without them realizing.
Naruto's character development would likely become more complex. With the Rinnegan and Sharingan, he would have access to a whole new level of power and knowledge. He might become more introspective as he tries to understand and control these powers. His relationships could also change. For example, his friends might view him differently, with a mix of awe and perhaps a bit of wariness due to the potentially overwhelming nature of these powers.
Naruto might adapt by first trying to understand the basic functions of the Sharingan. He could start with the simple ability to see chakra flow more clearly. Since he has always been perceptive about people's emotions, he could use the Sharingan to read the emotions of his enemies through their chakra, which would help him in battles.
Sakura could be an unexpected character to have the Sharingan. It would completely change her character dynamics. She could use it to enhance her medical ninjutsu, seeing the internal body structure more clearly. Also, she could become a more formidable fighter, using Sharingan - based genjutsu to her advantage.
Yes, in certain fanfictions. Fanfic writers sometimes take creative liberties and bestow the Sharingan on Naruto. It could be for the sake of exploring new power dynamics. For example, if Naruto has the Sharingan, his already formidable combat skills could be enhanced even further. This might change the way he approaches battles and his relationships with other characters, especially those who also have the Sharingan, like Sasuke.
One reason could be that some fanfiction authors might focus more on other aspects like new jutsu or character relationships outside of the Uchiha clan. They may not fully understand the potential of Sharingan, which has a wide range of abilities from basic perception enhancement to powerful genjutsu. Another factor could be the over - popularity of some other elements in the Naruto universe, like the tailed beasts, which overshadow the Sharingan in their stories.
