If Naruto had the Sharingan in fanfic, he'd likely become even more powerful. His combat skills would improve as he could use the Sharingan to predict his opponents' moves more accurately. He might also be able to use some of the unique jutsus associated with the Sharingan. For example, he could potentially learn to use Amaterasu if the fanfic writer allows for that kind of power combination.
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.
In a fanfic, Naruto with the Rinnegan and Sharingan would have a whole new set of challenges. He would have to deal with the jealousy and fear of other ninja villages. His own village might also be divided on how to handle his new powers. On the positive side, he could use these eyes to better understand the history of the ninja world. For example, the Rinnegan might give him insights into the Sage of Six Paths' true intentions, and the Sharingan could help him uncover secrets about his own family. He would also have to train hard to fully utilize the combined potential of these two powerful eyes, which could lead to some interesting training arcs in the fanfic.
Well, if Naruto was born with the Sharingan in fanfiction, it would be a game - changer. Firstly, his training with Iruka and later Kakashi would be different. Instead of focusing on his own natural chakra and the Rasengan, he could also be trained to master the abilities of the Sharingan. This could potentially make him a much more powerful ninja at a younger age. And in battles, he could use the Sharingan's predictive abilities to dodge attacks more effectively and counter - attack with greater precision.
The presence of the Sharingan could also change the character's relationships. Other characters might be in awe of this new power, or they could be suspicious and fear it. The character with the Sharingan would have to deal with these new attitudes. They might be seen as an outcast or a powerful ally depending on how they use their power. It could also attract the attention of the gods or more powerful beings in the Percy Jackson universe, who might want to either control or destroy this new and unknown power.
Well, in a fanfiction where Naruto is trained by Itachi in Sharingan, Naruto would first have to adapt to the new power. Itachi would probably start with the basics of how to activate and control the Sharingan. Since Naruto is used to his own physical and chakra - based training, this would be a challenge. However, with Itachi's guidance, he could master it. Once he does, he could use the Sharingan to analyze his opponents' fighting styles better. For example, he could quickly figure out the weaknesses in an enemy's jutsu and counter them effectively. He could also use the Sharingan's visual prowess to enhance his reaction time during battles.
Naruto would likely become even more powerful. With the Sharingan, he could copy jutsus more easily, which would be a huge advantage in battles. He might also gain some of the Uchiha's unique abilities like seeing through illusions better.
In this fanfiction, Naruto would become extremely powerful. With the Sharingan, he could gain abilities like predicting movements and copying jutsus more effectively. The Rinnegan would give him powers such as the Six Paths techniques. He might be able to use these newfound powers to better protect Konoha and face stronger enemies.
In fanfiction, if Naruto got the Sharingan from Madara, it would completely change his power dynamic. He would gain the abilities of the Sharingan like enhanced perception, the ability to copy jutsu more easily, and perhaps even access to some of Madara's unique Sharingan - based techniques. This would make him an even more formidable opponent and could potentially change the entire plot of the Naruto universe within the fanfiction world.
Naruto would become much more powerful. The Sharingan could give him an edge in battles, allowing him to copy jutsu more easily. He might be able to use it to analyze his opponents faster. However, he would also have to deal with the negative aspects of the Sharingan, such as the potential strain on his eyes and the risk of overusing it.
