One idea could be that Naruto is captured by an unknown enemy. While in captivity, he loses his sight due to some sort of dark jutsu used on him. His friends then embark on a journey to rescue him. In the fanfiction, they might face various challenges and new enemies along the way.
Maybe Naruto is captured by a powerful and mysterious foe. This enemy blinds him as a form of torture. Naruto's friends and allies in Konoha soon notice his absence and begin a search. Naruto, while in captivity, tries to figure out the motives of his captors. He also tries to find ways to escape, using his chakra to sense his surroundings despite his blindness.
Yes, there are likely fanfictions with such a concept. Fanfiction writers often come up with unique and creative ideas, like a godlike Naruto who is blind. It could explore how Naruto overcomes his blindness while still having his godlike powers, perhaps delving into his other senses and how they are heightened to compensate. There might be different interpretations of how his relationships change as well, such as with his friends and foes.
One way is to focus on Naruto's other senses. For example, his sense of smell could become super enhanced, like a ninja version of Daredevil. He could use it to track enemies, find his friends in a crowd, or even detect hidden traps. His hearing could also be sharpened, allowing him to hear the faintest of footsteps or the rustling of leaves from afar, which would be useful in combat situations.
Well, without reading the specific fanfiction, it could be about Kurenai, a character from Naruto, capturing Naruto for various reasons. Maybe it's part of a mission, or perhaps there's some misunderstanding that leads to this situation.
One interesting plotline could be the blind prodigy's journey to overcome the limitations of blindness. For example, they might develop a unique way of sensing chakra that is even more powerful than normal sight. Maybe they can sense the flow of chakra in people and the environment to predict attacks and movements, much like how Neji could see the chakra points. Another plotline could be their struggle to be accepted in the ninja world, where physical abilities are often highly valued. People might initially underestimate them because of their blindness, but they prove themselves to be a force to be reckoned with.
Well, obviously the blind prodigy themselves is a key character. There could also be original characters created specifically for the fanfiction. For example, a rival who also has some sort of disability but uses it in a different way. Another potential character could be a healer who helps the blind prodigy learn to use their other senses better. And of course, existing Naruto characters like Naruto, Sasuke, Sakura, and Kakashi are likely to make appearances. They could interact with the blind prodigy in various ways, like Naruto being a source of motivation or Sasuke being a foil to the blind prodigy's more positive attitude.
It could be other villages as well. Since Naruto has made friends and allies from different villages during his adventures. For example, the Sand Village might send some of their ninja to help, considering Naruto's relationship with Gaara.
Another way is that he forms an unexpected alliance within Iwa. There could be a dissident group in Iwa who oppose the capture of Naruto. They might help him escape in exchange for some future favor or because they believe in Naruto's cause. Naruto has a way of inspiring people, even those who are initially his enemies, so this is a plausible scenario.
