Often, the main character is an original character created specifically for the fanfiction. This character is usually the one with the rainbow eyes, like a young ninja who discovers their unique eye power and has to learn how to use it in the Naruto world.
In some 'Naruto Rainbow Eye Fanfiction', the rainbow eyes might be a symbol of a long - lost clan. The story could revolve around the protagonist with these eyes trying to discover their clan's history and the secrets behind their special eyes while facing challenges from other ninja clans who are either envious or afraid of their power.
There's also the possibility that it's an accidental injury caused by one of Naruto's friends during a training session gone wrong. For example, Sasuke could accidentally unleash a jutsu that hits Naruto's eye while they are sparring.
One consequence could be that Naruto becomes more isolated. He may feel like he's a burden or that he's not as strong as he used to be. However, this could also lead to him becoming more determined to overcome his disability. He might train harder to develop his other senses, like his hearing and sense of smell, to make up for the loss of his eye. This could ultimately make him a more well - rounded and unpredictable fighter.
Well, it could be due to a powerful enemy attack during a fight in Wave. Maybe an enemy with a sharp weapon or some dangerous jutsu managed to strike Naruto's eye.
A more complex fanfiction could involve a villain who is stealing both chakra and the magic that powers Rainbow Dash's world. Naruto and Rainbow Dash would have to combine their unique abilities. Naruto could use his Rasengan, and Rainbow Dash could use her Sonic Rainboom to defeat this powerful villain.
It could be a fan - made story that combines elements from Naruto and the concept of the Millennium Eye. Maybe it's about a character in the Naruto universe who somehow obtains or is related to the Millennium Eye, which could lead to all sorts of new adventures, power - ups, and different plot twists compared to the original Naruto story.
Another character that could be a main character in 'eye naruto fanfiction' is Hinata. Her Byakugan gives her a unique perspective and ability. If the fanfiction is about new eye powers or a combination of different eye powers, Hinata could play a significant role. For example, if Naruto were to somehow gain a Byakugan - like power, Hinata could be the one to help him understand and control it.
I'm not sure specifically as there could be many different interpretations in Naruto fanfiction with the 'emperor eye' concept. It might be about a new type of dojutsu (eye power) that a character has in the Naruto universe, perhaps with abilities like enhanced perception, the power to control others, or unique combat skills.
One possible fanfiction could be about Naruto learning to fully control the power of his Kyuubi - enhanced eye. He might discover new abilities like seeing through illusions more easily or being able to project his chakra in a more powerful way through his eyes. This could lead to him having an edge in battles against tough opponents.
