One possible consequence is that Naruto would gain enhanced visual abilities. The Sharingan can see chakra flow clearly, which would be a great asset in battle for Naruto. He could better analyze his opponents' moves and weaknesses.
With his other friends like Choji and Kiba, they might see Naruto as even more of a leader. The Sharingan is a symbol of great power, and Naruto obtaining it could inspire them to train harder. However, they might also feel a bit of a distance at first, as Naruto now has a power that is quite different from what they have. But overall, Naruto's positive nature would likely help him maintain strong relationships with his friends as he'd assure them that he'll use the power for good.
Well, Naruto already has his own powerful abilities like the Nine - Tails chakra. But getting Kakashi's Sharingan could enhance his perception skills. He'd be able to see attacks better and react faster. Maybe he could even copy some jutsu more easily, just like Kakashi used the Sharingan to copy many jutsu in the original series.
I really like 'Obito's New Path'. In this fanfiction, Obito gets a second chance in a different reality. His Sharingan abilities are explored in unique ways, like how he uses it to understand the true nature of the ninja world. The story also has great character development for Obito and other Naruto characters.
In some fanfictions, it could be due to a special jutsu gone wrong. Maybe a jutsu that Kakashi was using to transfer some of his chakra to Naruto for a mission accidentally transferred his Sharingan power as well.
One great Kakashi x Obito fanfiction is 'The Bonds We Share'. It delves deep into their relationship, exploring how their past experiences shape their interactions in a post - war Konoha. It shows their growth and how they come to understand each other on a deeper level.
One great fanfiction could be about Kakashi using his Sharingan to train Naruto in a special jutsu. Maybe he shows Naruto how to better perceive an opponent's moves by using the Sharingan's ability to analyze. This could lead to Naruto developing a new and powerful technique that combines his own chakra control with the insights from the Sharingan.
There's also 'Sharingan - Naruto's New Power'. In this fanfic, Naruto gets Obito's Sharingan in a rather unexpected way. The story focuses on his journey to master this new power. It has some interesting plot twists, such as Naruto having to face off against enemies who are specifically targeting him because of his newfound Sharingan ability.
In many 'naruto has obito sharingan' fanfics, a unique aspect is the new combat potential. Naruto already has his own powerful techniques, and adding the Sharingan gives him an edge in battle, like enhanced perception and the ability to copy enemy jutsu more effectively.
Some Naruto - focused forums also have sections dedicated to fanfiction. For example, NarutoForums.com. Members often share their own 'Obito Sharingan' fanfictions there or recommend good ones they've read. It's a great place to interact with other fans and discover new stories.
