When Sasuke's Rinnegan was first introduced in the Shippuden anime, it shook the fandom as it made him one of the most powerful shinobis at the time, along with Naruto. Unfortunately, however, a shocking incident caused him to lose his Rinnegan in the Boruto manga series.
As of the time of writing, Sasuke Uchiha has not gotten his Rinnegan back in Boruto. Sasuke Uchiha lost his Rinnegan to Boruto, who was actually possessed by Momoshiki Ōtsutsuki at the time, who stabbed him directly in the eye, thereby destroying the Rinnegan and taking its powers away from Sasuke.
No, no he will not.
How weak is Sasuke after losing his Rinnegan? He actually mostly fights with his Sharingan more then his Rinnegan. He uses it occasionally for Amenojikata or dimension traveling but not much else. He isn't as strong as when he did have the Rinnegan, but he's still borderline the strongest shinobi in the world.
No, Naruto cannot even regenerate Sauske's sharingan. This is because Naruto had the sun seal. The sun seal, when used with it's counter part the moon seal, granted the power to seal a massive beast such as Kaguya just with a touch. Being a gift from Hagaromo, it came from his abilities.
After receiving half of Hagoromo Otsutsuki's chakra during the final battle against Kaguya, Sasuke awakened a Rinnegan in his left eye, which allows him to use all the Six Paths Techniques, plus one space-time manipulation power that is unique to Sasuke's Rinnegan, and that will...
Sarada suffered from an illness that nearly killed her. Maybe Sakura didn't want to try anything invasive which would put Sarada at risk, when glasses are an easy, non-invasive fix. I've worn glasses since childhood, and experienced multiple prescription changes over the years.
Because Tailed Beasts are life-forms made of pure chakra, they are eventually reborn after dying. They will always come back, but until that happens, they're factually dead. So, deliberately creating some new Tailed-beasts to get Kurama back does not seem like something Naruto would do.
How Naruto Can Regain Kurama. Kurama ended up burning away and, as such, there is no body left for him behind as he was a mass of chakra, to begin with. Thus, he cannot be resurrected using techniques such as Edo Tensei.
Now that Kurama is dead, will he come back? No, he ain't comming back. His chakra (his existence as he is made of it) was consumed and literally faded away which he himself stated.
For the most part, Sasuke only ever used one hand with any sword he used, giving him a burst of quickness with them, but that doesn't change that the lack of a second hampered him. It is especially true in a taijutsu fight where blows are coming at you so rapidly that you have little time to think.
While Boruto's human eye is lost, the Jogan that he possesses is still alive. The Jogan was seen getting triggered shortly after Kawaki slashed his right eye. As fans know already, the emergence of the Jogan usually indicates that Momoshiki has taken control over Boruto's body.
Although Naruto usually uses the Six Paths' Sage Mode along with the Kurama Chakra Mode, there is no reason he cannot use it without Kurama's strength. In fact, Naruto can still use the basic Sage Mode, which is enough for him to take down a roster of enemies.
The Next Power Of Naruto Uzumaki
While most fans consider Naruto to be past his prime, he can still train and grow stronger. Even without Kurama, Naruto can attain great mastery of all forms of jutsu and get even stronger.
Yes, Naruto can technically acquire the Rinnegan, but it's not a straightforward process. In the Naruto manga and anime series, the Rinnegan is a rare and powerful dojutsu that can only be awakened by those with both the Uchiha and Senju bloodlines.
No, he isn't. He is still capable of using his strongest mode which was granted by Hagoromo. Six Paths Sage Mode: This mode increases the user's physical parameters well above that of Sage Mode and the Nine-Tails Chakra Mode.
Despite the loss of his dear friend, the Seventh Hokage can still use the Sage Mode. Fans were delighted to see that Naruto still retained some of his powers and that he is capable of taking down strong opponents. However, he had to use Shadow Clones in order to collect the natural energy.
Although Boruto: Naruto Next Generations has already shown a Ten-Tails, it is unlikely that Kurama can be revived or extracted from it. Furthermore, the Baryon Mode essentially uses up Kurama's life-force, rendering it practically impossible for him to be revived in some way.
Naruto has always been a powerful character, but his possibility of obtaining a new-tailed beast after Kurama's death could make him stronger. The increased power from the new-tailed beast could surpass even Baryon Mode, making Naruto a force to be reckoned with.
Although Naruto lost Kurama, he still has access to the powers of the other Tailed Beasts. During the Fourth Great Ninja War, he received a portion of the chakra of every Tailed Beast and has utilized this power to a great degree in all his fights since.
It turns out the Tailed Beasts never actually die, but they reincarnate over the years. The first instance of a Tailed Beast dying happened with Isobu. The monster was killed alongside his host, and it forced the beast to reform over the years.
This Tailed Beast is capable of destroying the world if it wanted to. Kurama in Naruto stated that no matter what it throws, it will not be able to defeat the Ten-Tailed Beast. The difference in power levels is far too high, which is why the Ten-Tailed Beast is stronger than Kurama in the Naruto series.
Naruto in the sage of six paths mode can heal others (stabilized Guy's life force, resuscitated Obito Uchiha after having the Ten Tails ripped out of his body and restored Kakashi's left eye) so he can restore Sasuke's eye, if not the rinnegan then at least the sharingan.....
