Naruto would adapt to Obito's Sharingan by relying on his strong will and his existing combat experience. He's faced many challenges before, and this would be just another one. He'd probably train with Kakashi or Sasuke to understand the Sharingan better. Since he has such a large amount of chakra, he might be able to use the Sharingan's power more frequently than others. He would also try to incorporate it into his existing fighting style, for example, using it to enhance his Rasengan or his taijutsu.
First, Naruto would have to come to terms with having a power that is so different from his own natural abilities. He might initially struggle with the idea that it's not something he achieved through his own hard work like his Sage Mode or his chakra control. But once he accepts it, he'll start to adapt. He'd use his unique ability to make friends and understand others to learn from those who know about the Sharingan, like Kakashi. He would practice using it in non - combat situations first, like using it to read small details from a distance. Then, as he gets more confident, he'd use it in battle. He might face some setbacks, like accidentally overusing it and straining his eyes, but his determination would help him overcome these and fully adapt to the new power.
Well, Naruto getting Obito's Sharingan would change the whole dynamic of the Naruto universe. His friends might be a bit wary at first, as the Sharingan has been associated with the Uchiha and their often complex and sometimes dark history. But Naruto being Naruto, he would probably use it for good. He could combine his own chakra control and the power of the Sharingan to create new and unexpected combat strategies. For example, he could use his shadow clones in more creative ways, with the Sharingan's enhanced perception.
Naruto might adapt by first trying to understand the basic functions of the Sharingan. He could start with the simple ability to see chakra flow more clearly. Since he has always been perceptive about people's emotions, he could use the Sharingan to read the emotions of his enemies through their chakra, which would help him in battles.
His character would become more complex. With these new powers, he might face new moral dilemmas. For example, the power of the Rinnegan could tempt him to use it in ways that might not be in line with his usual values.
Naruto's character would likely become more complex. He'd have to deal with new powers and the responsibilities that come with them. He might become more introspective as he tries to understand the nature of the Sharingan and how it fits into his ninja beliefs.
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.
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.
Naruto would become more introspective. The power of the eternal mangekyou sharingan often comes with a lot of emotional baggage in the Naruto universe. So Naruto might start to question more about his own identity and his place in the ninja world. He might also become more cautious as he realizes the great power he now holds and the potential for misuse.
Naruto's fighting style would change significantly. He would no longer rely solely on his brute strength and Rasengan - based attacks. The Sharingan would allow him to see the flow of chakra more clearly, so he could target his opponents' weak points more precisely. He could also use genjutsu, which he has little experience with before. Maybe he would combine his shadow clones with the Sharingan's abilities, for example, having clones with Sharingan - enhanced vision to scout the area better during a battle.
The Sharingan might also give Naruto the ability to enter people's minds, at least to some extent. In the Naruto universe, the Sharingan has been shown to have some mind - related abilities. Naruto could use this to communicate with his friends in a more direct way, or perhaps even to break through genjutsu more easily. And, if he can enter the minds of his enemies, he could gather valuable information about their plans and weaknesses.
Naruto would gain the ability to copy jutsu. With the Sharingan, he could watch an opponent's movements closely and replicate their techniques. This would be a huge advantage for him in battles.
