One possibility is that Naruto would gain incredible new abilities. Shisui's Sharingan had unique powers like Kotoamatsukami. With it, Naruto might be able to influence others in a more subtle way. He could use it in battles to deceive opponents or even resolve conflicts without direct combat. For example, he could use it to make enemies see illusions of peace and lay down their weapons.
It would likely expand his Ninja Way. Naruto's Ninja Way is about protecting his friends and the village. With Shisui's Sharingan, he could protect them in more ways. He could use the Sharingan's perception abilities to detect threats earlier and act accordingly.
Well, if Naruto gets Shisui's Sharingan in a fanfiction, he could gain some really cool abilities. The Sharingan has powers like enhanced perception and the ability to copy jutsu. Naruto already has his own powerful chakra and skills, so with the Sharingan, he might become an even more formidable ninja. He could potentially use the Sharingan's genjutsu capabilities to his advantage in battles, maybe even use it to break through tough enemy defenses more easily.
In a fanfiction, if Naruto gets Shisui's Sharingan, he might face consequences in his training. He would need to learn how to control and master this new power, which could take time away from his normal training. This could potentially slow down his progress in other areas, like his Rasengan training or his control over the Nine - Tails' chakra. Also, his relationships with his non - Uchiha friends might be affected. They could feel left out or less important to Naruto now that he has this powerful Uchiha ability.
In this kind of fanfiction, Naruto might obtain Shisui's brother's Sharingan through some unforeseen events. Maybe Shisui's brother sacrifices himself and entrusts his Sharingan to Naruto. As for new abilities, it could enhance Naruto's perception skills like being able to see through genjutsu more easily and also improve his combat awareness in battles.
In this fanfiction, a likely plot development could be that Naruto starts to experience strange visions or memories from Shisui's brother due to the Sharingan. This causes him to go on a journey to discover the secrets behind these visions. Also, the Leaf Village elders might become suspicious of Naruto's new power and try to keep an eye on him, which creates internal conflicts within the village.
In fanfiction, Shisui's Sharingan often has some unique abilities. It's usually depicted as having powerful genjutsu - related powers. For example, it might be able to cast illusions on multiple opponents at once with greater ease compared to a normal Sharingan. His Sharingan can also potentially be used to transfer memories in more creative ways in fan stories, like not just the basic memory transfer we saw in the original Naruto series but perhaps more complex emotional and skill - based memories.
In some fanfictions, Shisui's Sharingan has a different color or pattern. This is a simple but effective way to make it stand out. For example, it could be a deeper red or have an extra swirl in the pattern.
Well, if Naruto gets Shisui's Sharingan in the fanfiction, it could greatly enhance his perception skills. He'd be able to see chakra flow more clearly, which would help him in combat. He might also be able to use some of the Sharingan - specific jutsus like the Genjutsu techniques related to it. This would make him even more formidable against opponents, especially those who rely on stealth or illusions.
Naruto's character would likely become more serious and focused. Training with Shisui and the Sharingan would demand a lot of concentration, so he'd have to tone down his wilder side. He might also become more strategic in combat, as the Sharingan gives insights into opponents' moves.
