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.
Naruto Can Use His Jutsus In Kurama Avatar Mode
This is visible from every tailed beast transformation witnessed so far, as the only abilities that they are able utilize are the ones that the beasts themselves possess.
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.
As the Jinchuriki of Kurama, Naruto was quite powerful and ranked among the strongest Hokage in the story. However, after losing the power of his Tailed Beast in the fight against Isshiki Otsutsuki, he has weakened quite a bit.
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.
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.
Baryon Mode powered Naruto Uzumaki up to great levels, and made him strong enough to overpower Isshiki Otsutsuki in battle. This transformation made him the strongest character in the story, and is Naruto's strongest form by far.
That plan ended up being Naruto's new form, Baryon Mode. Baryon Mode involves Naruto and Kurama's chakra coming together to create new kernels of power, a process that Kurama likens to nuclear fusion.
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.
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.
To the fandom it seems that, although it would be extremely difficult, it is not impossible, and at worst the fight might result in a draw. The reason for that is, even without Kurama, Naruto still retains his Sage of Six Paths mode and his own Sage Mode that he mastered through training.
No, he isn't. He is still capable of using his strongest mode which was granted by Hagoromo.
With Kurama, Naruto would be able to subdue Borushiki and fight him on a more level playing field, but without Kurama, it is the opposite. Although Naruto would not be able to use ninjutsu even with Kurama, having Kurama allowed him to add a lot more diversity to his fighting style.
Delta managed to push back a Six Paths enhanced Naruto and could even have killed him had luck been on her side. Currently, she has been deactivated by Amado but her body is unharmed. Without Kurama at his aid, Naruto's power level is certainly below the likes of Delta.
With Baryon Mode, however, Naruto could not only dodge the rods but also catch them as if they were an insignificant threat to him, which just goes to show that Baryon Mode is that much more powerful than Six Paths Sage Mode.
1) Madara Uchiha
However, Baryon Mode Naruto can easily surpass him, even using high-level Taijutsu, as this mode grants him insane raw strength.
Baryon Mode is incredibly powerful and it even lets him overwhelm Isshiki Otsutsuki, the strongest known Naruto character in battle. However, Naruto is certainly not unbeatable in this form and there are characters who could deal with this power of his effectively.
Like Sasuke, Naruto was gifted with Six Paths Powers from the Sage of Six Paths himself, making him one of the strongest people out there. He also gained the chakra of all nine of the Tailed Beasts, making him a pseudo-Ten Tails Jinchūriki.
The only two ways Naruto can get the rinnegan is through blood transfusion from Sasuke or absorb enough of Sasuke chakra and merge with his chakra.
Boruto: Will Boruto And Kawaki Surpass Naruto And Sasuke? Boruto and Kawaki might be on the path to surpass their predecessors Naruto and Sasuke. Boruto Uzumaki is the main character of the Boruto series, and, just as Naruto had his Sasuke in his story, Boruto has his Kawaki.
Now that he is without Kurama, Naruto has reason to further develop his Sage Modes, mastering an even higher level of Senjutsu than he originally thought possible. With Sage Mode granting him access to all five chakra natures, his ability to learn new types of jutsu is essentially infinite.
Naruto also ended up receiving the Six Paths Senjutsu from the Sage of Six Paths and when combined with his Sage Mode, it gave rise to one of his strongest forms called the Six Paths Sage Mode. In this form, Naruto became strong enough to fight the likes of Madara Uchiha and even Kaguya Otsutsuki.
