He has trouble moving around. Without sight, he can't easily navigate the village or the forest. He might constantly bump into things. Also, in combat, he can't see his opponents' attacks coming. It's a huge disadvantage compared to when he could see.
One interesting masked ninja is Shinji. He is a masked character in fanfiction who was once a normal ninja but got cursed by an ancient evil. Now, with his masked identity, he tries to find a way to break the curse while also using his new - found dark powers for good in the Naruto world. There's also a masked ninja named Yuki. Yuki is a snow - style user and her mask is made of ice crystals. She is on a quest to find the origin of her ice - based powers. Another is Hikaru, a masked ninja with the power of light, who is often at odds with the darker elements in the Naruto fanfiction world.
His relationships would change a great deal. The other ninja villages may view him as a threat or a potential ally in a different way now. Since he's the heir of the fire daimyo, some might try to use his new position for their own gains. His relationships with the villagers of Konoha would also be different. He would be seen as a future leader in a more direct sense, and some might be jealous or overly deferential to him.
One possible fanfiction could be about a Naruto ninja who has a special mouth technique. Maybe it allows him to speak different languages and he uses this ability to communicate with various enemies and allies during a mission. He could be on a quest to find an ancient scroll that holds the secrets to enhancing his mouth - related jutsu.
One popular plot idea is a masked ninja being a long - lost relative of a main character. For example, they could be related to Naruto and have been in hiding all this time. Another idea is a masked ninja being a spy from another village, with a complex backstory of loyalty and betrayal. Also, there could be a masked ninja who is a time - traveler, coming from the future to change key events in the Naruto universe.
One interesting fanfiction could be about a ninja from Amegakure who has a special ability that is not shown in the original Naruto series. For example, the ninja might be able to control the rain in a more unique way than Pain. They could use it to create illusions within the raindrops, making it difficult for enemies to distinguish between reality and the false images.
The relationship between Naruto and Sakura in this fanfiction is also a key point. It could be that their bond is strengthened in ways not shown in the official story. Maybe they support each other more deeply during their ninja journey, facing enemies and making difficult decisions together.
One possible story could be Sasuke in an alternate universe where the events of 'Road to Ninja' take a different turn for him. Maybe he teams up with Naruto earlier and they face the challenges together, with Sasuke having to confront his inner demons in a whole new way.
Typically, a 'naruto ninja harem fanfic' involves Naruto having multiple romantic interests among the female ninja characters. There's often a lot of focus on the relationships and the drama that comes with it.
Perhaps it means that the Naruto story being referred to is an original take on the Naruto universe and not just a derivative fan - made story centered around ninjas. It might focus on other aspects like the characters' personal growth outside of their ninja skills or different relationships that are not typically explored in ninja - centric fanfics.
