Yes, there are likely some Naruto fanfictions out there where Naruto has a blue Sharingan. Fanfiction writers often come up with creative and unique ideas like this. They might explore how Naruto's character would be different with this new ability, or how it would change the existing storylines in the Naruto universe.
Yes, there are likely some fanfics out there with this concept. The Naruto fandom is vast and creative, and some authors might come up with the idea of Naruto having a blue Sharingan for the sake of unique storylines, crossovers, or just to explore different power combinations within the Naruto universe.
Perhaps Naruto gets the blue Sharingan as part of a forbidden ritual that was meant to save the Hidden Leaf Village from a powerful dark force. This would lead to him being shunned by some villagers who fear his new, unknown power. He would then have to prove himself and his intentions with the Sharingan. Also, it could be that the blue Sharingan is a key to unlocking a hidden dimension that holds the secrets to ultimate ninja power, and Naruto embarks on a journey to explore this dimension.
Maybe in the fanfic, Naruto enters an alternate dimension where the Sharingan is blue. He discovers that he has this new - found ability and must use it to find his way back home. Along the way, he meets different versions of his friends and foes, and the blue Sharingan gives him an edge in battles and also helps him understand the secrets of this strange dimension.
Well, he'd probably be extremely powerful. The Sharingan already gives some great abilities like enhanced perception and the ability to copy jutsu. If Naruto had a blue Sharingan, he might be able to combine those with his own massive chakra reserves. Maybe he could use the Sharingan to better understand and counter his opponents' moves while using his Rasengan or other jutsu more effectively.
One interesting story could be about a character who has a unique combination of the blue chakra and the Sharingan's powers. Maybe they use it to see through illusions that are even stronger than normal. They could go on a journey to discover the origin of this strange power combination.
One interesting concept could be a character having a blue Sharingan as a unique mutation. It might give them abilities different from the traditional red Sharingan in Naruto. For example, they could have enhanced precognition abilities, being able to see a few seconds further into the future in combat situations. This could make them a formidable opponent or a great ally.
In fanfiction, many things can be made to make sense even if they deviate from the original canon. Naruto having a blue Sharingan could be a creative twist. Maybe it was the result of some experimental jutsu or a strange encounter with Uchiha - related powers. It could open up new storylines and character developments.
One drawback could be the strain on his body. The Sharingan is a powerful dojutsu, and Naruto's body, which is used to his own chakra system, might not be able to handle it well at first. This could lead to fatigue and over - exertion during battles.
