Sasuke is also frequently a main character in these fanfics. Imagine if Sasuke had red eyes instead of his Sharingan. It could completely change his character arc. He might be even more of an outcast or have a different set of powers that make him both feared and respected. And then there are the Akatsuki members. Some fanfics might make one of them have red eyes and explore how that changes their role within the organization and in the overall Naruto story.
In 'Naruto Red Eyes Fanfic', Kakashi could be a main character with red eyes. Since he already has the Sharingan in his left eye, a fanfic could give him red eyes in his right eye for some special reason. This could enhance his abilities even further. Maybe the red eyes give him the ability to sense danger on a whole new level or communicate with some special type of spirit animals that are only attracted to those with red eyes.
Sasuke is another character who might be involved as a main character in such fanfictions. If the red - eyes concept is related to the Sharingan or some new form of eye power, Sasuke's connection to the Uchiha and their eye powers makes him a likely candidate to be part of the story. The red - eyed character might be his ally or rival.
Obviously, Naruto is a main character in these fanfictions. He's usually the one who gets the red eyes and the connection to the Darkness Dragon. Sasuke might also be involved, either as a rival who is intrigued by Naruto's new power or as a partner in exploring the secrets of the red eyes. Sakura could be there as well, perhaps trying to help Naruto control the power so it doesn't consume him. And sometimes, characters from other clans or villages might make an appearance, like Gaara, who might be interested in the power because of its potential threat or its possible use in protecting his own village.
Often, Naruto himself can be a main character in Naruto cold eyes fanfiction. The story could explore how he interacts with a character who has cold eyes. Another common main character could be a new, original character created specifically for the fanfiction, who has these cold eyes and has a significant role to play in the Naruto - inspired world.
Often, Naruto himself might be associated with it. Since he is the main character in the original series, fanfiction writers may give him sage eyes and explore how it changes his character and abilities.
Often, the yellow guy might be paired with the red guy in fanfic. They could have a friendship - based story where they go on various escapades together.
Since I don't know the exact fanfic, it's hard to say. But it could have a brave hero who tries to face the red - eyed dragon. There might also be a wise old wizard or mentor type character who knows about the dragon and the significance of the meteor.
Sometimes, Sasuke can also be a main character in 'Naruto Yellow Eyes Fanfic'. He might be intrigued by the power of the yellow eyes. He could either be in competition with the character who has the yellow eyes or be trying to help them master their power, depending on the direction of the fanfic.
Obviously Naruto would be one of the main characters. He is the central figure around whom the'seeing red' concept is likely based. There may also be his friends like Sasuke and Sakura, as they are often involved in Naruto's storylines and could be part of the events that make him see red.
Obviously, Naruto is likely to be one of the main characters. There might also be some original characters created for this fanfic who are native to the area of the red sand. And perhaps some of Naruto's friends from the original series like Sasuke or Sakura could also make appearances depending on the plot.
It's hard to say without actually reading the fanfic, but it could be a new character who has the red rinnegan. Maybe this character is an outcast from a well - known ninja clan because of their unique eye power. Or it could be an existing character from the Naruto series who somehow acquires the red rinnegan and then becomes the focus of the story.
