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.
Minato might also be a prominent character. As their teacher, he can influence the way Obito and Kakashi interact. In some fan fictions, he could be the one to help them resolve their differences or provide some crucial information about their past that changes their current situation.
One idea could be a story where Female Kakashi and Obito are on a mission together in a mysterious land filled with ancient magic. They have to rely on each other's skills to survive and in the process, they start to see each other in a new light.
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.
One possible thing that could happen is Naruto would gain new visual abilities. With the Sharingan, he might be able to copy jutsus even more effectively than before. The Sharingan could also potentially enhance his perception of his opponents' moves, making him an even more formidable fighter in battle. This could change the power dynamics in the Naruto universe significantly.
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 plot implication could be that Naruto becomes an outcast among some in the village who fear the power of the Sharingan. This would create internal conflict within Konoha. Another is that Naruto might be targeted by enemies who want to either steal the Sharingan or kill him to prevent him from becoming too powerful. Also, it could change his relationship with Sasuke, as they both now share a connection to the Sharingan.
Well, the plot could start with Itachi realizing that Naruto is the key to the future of Konoha and the ninja world. So, he gives Naruto his Sharingan. Naruto then has to deal with the new power. He might start having visions related to Itachi's past, which could help him understand the Uchiha - Senju conflict better. And this new knowledge could influence his decisions in future battles and political situations in the ninja world.
