Fifteen years after the Fourth Shinobi World War, Naruto and Killer B are the only two jinchūriki left in the world, as a result of the changes that came about. However, after Naruto lost Kurama via the Baryon Mode, Killer B is now the last Jinchūriki in existence.
No, Naruto will not become a jinchuriki in the Boruto anime, as he would not want to replace Kurama just to get stronger. While he was the strongest living character in the verse, losing Kurama was a huge blow to him as well as the Hidden Leaf Village.
Even without Kurama, Naruto is still a Jinchuuriki and the strongest among the hokages. How is he still a Jinchuuriki without Kurama, you ask? Well, he was already the Jinchuuriki of all tailed beasts(except Ten-Tails) since Shippuden.
He also gained the chakra of all nine of the Tailed Beasts, making him a pseudo-Ten Tails Jinchūriki. Even though Naruto is already stronger than the Ten Tails, his strength continues to grow even today.
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.
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.
However, the recent happenings in Boruto have opened up room for Kurama to return. This return can be made possible through a Shinjutsu that was recently introduced in Boruto, named Omnipotence. Omnipotence is a power that was once wielded by Shibai Otsutsuki.
After the death of Kurama, he lost the large chakra pool he once had due to the Nine Tail. That played a huge role in performing some of the techniques that demanded a lot of chakra. In conclusion, it is doubtful that he would receive another power-up in the Boruto series.
At best, Sasuke might be slightly stronger than Naruto without Kurama. However, in the worst case scenario, he might be substantially weaker than the Seventh Hokage. A fair comparison can only be made once both these characters display their true strength after the loss of Kurama and Rinnegan in the Boruto series.
Monsters like Kurama can die, but they do not pass from physical wounds or age. Instead, they die when they expend more chakra than they can recharge, and they have tons of it. This has happened to Tailed Beasts in the past, but they do not stay dead forever.
Although Naruto lost Kurama, his Six Paths Powers should still be accessible to him. In Naruto's fight against Madara, he displayed the ability to use Six Paths Sage Mode without tapping into the power of the chakra cloak.
Some assume that his son, Boruto, is the obvious choice to be the next Nine-Tails jinchuriki but there are other ninja that could step up to the plate. Here are five shinobi that would make a better jinchuriki for Kurama than Boruto.
Although the Boruto anime has only just shown the Baryon Mode, fans know what it means for Naruto and Kurama. Baryon Mode is a strength only accessible to Kurama and his Jinchuriki, where the chakra of both fuse together, similar to nuclear fusion, and give rise to new energy.
With Naruto losing Kurama via the Baryon Mode, Killer B is now the last Jinchūriki in existence.
Where does Naruto land in the power level now that Kurama died? He would still be strong AF, He's an uzumaki, which are known to have lots of chakra. Kakashi said that if didn't have Kurama to hold down, naruto would have four times more chakra than himself.
In essence, both Boruto and Kawaki hold the power of the Otsutsuki Clan, and, as such, possess enough skill to rival the likes of Naruto and Sasuke. By this time in the story, they have, effectively, surpassed both of them.
The Zero Tails is the only type of tailed beast that was not created by the Sage of the Six Paths, Hagoromo Ōtsutsuki, alongside the other tailed beasts. However, in the film, the nine-tails, Kurama, reacted negatively upon its appearance implying that he has a past experience with the Zero Tails.
Can Sasuke bring Kurama back? No, sadly, he won't come back. Tailed Beasts are basically made of chakra, so when they're killed, they return to chakra and will be revived soon. However, Baryon mode consumes Kurama's chakra until he die, so there's no chakra left in him, that means he can't be revived anymore.
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.
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.
As strong as Sage Mode was, Naruto gained an even higher form of the power by the Sage of Six Paths. Known as Six Paths Sage Mode, this form takes all the benefits of Naruto's Toad Sage Mode and increases them exponentially, as well as adding a few more abilities. One such ability is his upgraded senses.
THIS is when Naruto mixed Six Paths Sage Mode with his Nine-Tails cloak. Some people get it confused. To answer your question, Naruto still has Six Paths Sage Mode after the death of Kurama, but he can no longer generate Truth-Seeking Orbs as he did in Naruto Shippuden.
