Well, it could make his combat style more versatile. He might be able to analyze his opponents' moves more precisely. With six eyes, he could have a wider field of vision, detecting attacks from more angles. Maybe he can use this new visual ability to anticipate his enemies' actions better and counter them with more effective jutsu combinations.
Well, one possible plot could be a character in the Naruto universe suddenly developing Six Eyes. This new power could disrupt the existing power balance. For example, they might be hunted by various ninja clans who either fear the power or want to use it for their own gains. Maybe this character has to go on a journey to learn how to control the Six Eyes and in the process, they meet some of the well - known Naruto characters like Naruto himself or Sasuke. They could form an alliance or have some conflicts depending on how the story unfolds.
In the fanfiction, the origin of Naruto having six eyes might be related to a special training or a forbidden jutsu. He could have stumbled upon an ancient training ground where he was exposed to some sort of energy or knowledge that granted him the six eyes. Or maybe he was forced to use a forbidden jutsu to save his friends during a critical battle, and as a side effect, he got the six eyes.
The story dynamics would change a great deal. Firstly, the mystery around the Six Eyes would draw in different characters. Some might be curious, some might be envious. This would create new relationships and rivalries. In addition, the training and development of the Six Eyes power would be a central focus. This could lead to different story arcs as the character with the power tries to master it, and other characters either help or hinder this process.
One common storyline could be Naruto being an outcast because of his yellow eyes. People might fear or misunderstand the power they represent, leading to Naruto having to struggle with acceptance. Another could be that his yellow eyes are the key to unlocking a special jutsu or a hidden realm within the Naruto world.
Well, if Naruto had 3 eyes in fanfiction, his visual perception would be greatly enhanced. He could potentially have a wider field of vision, like being able to see in more directions simultaneously. This might give him an edge in battle, as he could detect enemies coming from unexpected angles more easily.
Well, with Sasuke, Naruto's special eyes might make Sasuke see him as more of an equal. Since Sasuke has the Sharingan, Naruto's new eyes could level the playing field. They might have a newfound respect for each other and their rivalry could become more about who can master their new powers better.
If Naruto has Obito's eyes in fanfiction, his abilities would be enhanced in several ways. The Sharingan's ability to see chakra flow clearly would allow Naruto to better analyze his opponents' moves and weaknesses. With Kamui, he could teleport himself or objects, which would be a huge advantage in battles. He might also be able to use some of the more advanced Sharingan - related genjutsu, adding another layer to his combat skills.
One possible reason could be that his eyes hold a special power that he doesn't want others to discover easily. For example, it might be a new type of Sharingan or a unique ability related to his Uzumaki heritage that he needs to keep secret to protect himself or those around him.
