Boruto era Naruto Uzumaki stands tall as the strongest ninja in history; However, the Boruto The series has come with several nerfs that have significantly reduced his combat abilities. In Boruto Chapter 55, Naruto Uzumaki officially lost Kurama on January 9, 2024.
After losing his greatest source of power, Naruto Uzumaki must turn to other abilities to remain the strongest in the current era. While one would assume that Naruto is too weak to compete with those at the top of the current era, the Seventh Hokage actually has some powerful new jutsu that can help him take down even the most powerful villains in one hit.
After Kurama's defeat, Naruto's new strongest jutsu is the Super Ultra Big Ball Rasengan
When Naruto was in Kurama with the Uzumaki, he had access to a plethora of incredibly powerful techniques. Using the power of the Six Paths Sage Mode, Naruto could incorporate the Tailed Beasts' chakra into his abilities and create powers such as the Six Paths: Lava Release Rasenshuriken, which he used in his battle against Delta. Boruto Chapter 32, which was released on February 25, 2019. Naruto can also use incredibly powerful jutsu such as Beryon Mode, which originated it.

With such incredible powers, Naruto Uzumaki was practically unstoppable, but after losing Kurama, he lost his other skills. Now, Naruto Uzumaki's powers have been significantly upgraded with the use of a new Sage Mode, which was officially confirmed in Boruto Chapter 64 on November 19, 2021.
Using this incredibly powerful Sage Mode, Naruto Uzumaki can use his new strongest jutsu, and that is the Ultra Super Ultra Big Ball Rasengan. This new jutsu first debuted on March 25, 2019 in Boruto Chapter 33 in a battle against Delta. While Naruto's Rasengan have always been quite massive, the Super Ultra Big Ball Rasengan is the strongest and largest he has ever created. The fact that it overwhelmed Delta's chakra absorption and essentially put him on the brink of death meant that the technique could even work on Otsutsuki-level individuals.
Shikamaru: Naruto, you can't keep up this transformation for long, can you?
Naruto: Don't worry! My sage mode is much better than before. Call it the gift of wisdom.

While Naruto may appear weak on the surface, the fact is that he has yet to participate in any high-level battles since losing to Kurama. That means his power level might surprise us when it's revealed later down the line. With abilities like the Super Ultra Big Ball Rasengan, Naruto was able to take down Delta, meaning characters like Kinshiki were also falling for this technique. Others, such as Kod, would likely not be able to survive this technique, making it a terrifying ability that Naruto wielded with high precision.

Naruto's massive chakra reserve can still kill multiple enemies in 1 blow
Despite losing Kurama's power, Naruto Uzumaki still has a large chakra reserve. This is due to his Uzumaki bloodline, which is known to be particularly strong, but also because Kurama's chakra was embedded in Naruto's years. Even though Kurama is no longer there, chakra exists as Naruto's own, and while he's certainly taken a hit when it comes to his chakra reserves, what he has is still far greater than the vast majority of shinobi. With such a huge chakra reserve, Naruto Uzumaki could still create thousands upon thousands of clones and use techniques like the Super Ultra Big Ball Rasengan.

At the same time, he may be able to use a barrage version of this technique, ensuring that even the strongest enemies cannot stand in his way, especially when it is powered by his newly improved Sage mode. with Boruto: Two Blue Vortexes Now approaching its most exciting parts, the return of Naruto Uzumaki is also now on the horizon.

Why Naruto's improved Sage Mode could give him even stronger jutsu
One very interesting thing to note is that Naruto Uzumaki's Sage Mode is now incredibly powerful. He has officially upgraded this technique, which has extended its time limit and, at the same time, improved its overall power level. When Naruto returns, his sage art jutsu will be on a completely different level. Since he now has complete mastery over the five nature changes, Naruto can also use techniques once used by Jiraiya, such as the Sage Art: Bath of Boiling Oil. Similarly, Naruto can also power up his Earth Release, which he debuted on September 11, 2017 in his fight against Boruto Uzumaki, and at the same time, other nature changing techniques.
Most importantly, Naruto can expand his arsenal of weapons by incorporating powerful Genjutsu. Jiraiya's Sage Art: The Toad Confrontation Song Genjutsu was strong enough to take out a lot of pain at the same time. This Genjutsu can now also be incorporated into his arsenal by Naruto, giving him access to more incredible abilities. If Masashi Kishimoto and Mikio Ikemoto wanted to, they could easily make Naruto incredibly overpowered with just Sage Mode, giving him access to the most powerful and deadly abilities that exist in the world. That's something all us fans love to see too.
For now, Naruto's return will have to wait as Sasuke is first in line to make a comeback in the upcoming Hidari arc. As Sasuke makes his comeback, Naruto will eventually make a comeback as well, and only then will he get the chance to strut his stuff on the biggest stage once again.
