Six Paths Sage Technique

The Six Paths Sage Technique is an empowered state, similar to Sage Mode, which drastically empowers all of the user's abilities to a far greater extent by apparently combining senjutsu and the chakra of the nine.

Madara's Version
Madara has stated that he also possessed this technique. Whether this is purely from becoming the jinchūriki of the Shinju, or having prior absorbed Hashirama's Sage Mode chakra is unknown at this point.

Naruto's Version
While using this power, the user takes on a similar appearance to Sage Mode, while lacking the traditional pigmentation around their eyes that a normal Sage Mode would traditionally entail. The reason for this is not yet known, however. Naruto can extend the capabilities of the form by further drawing on the chakra of the nine, causing him to don a new variation of his Chakra Mode which is noticeably more powerful in comparison. In this new mode, like his original Tailed Beast Mode cloak, the chakra forms into a light-coloured coat but with a dark-coloured bodysuit underneath. The "bodysuit" covers his torso, reaches down his arms to the knuckles, and down his legs, stopping just above his sandals. It has a light colored circle where the original seal was placed as well as around his collar. The coat has the typical markings of the Six Paths Sage Technique; a Rinnegan above nine magatama, on its back.

Furthermore, Naruto is able to manifest the Truth-Seeking Balls, wielding two of them as short staffs. His speed is immensely increased as well to the point in which he can match Sasuke's instant teleportation by dashing. During the Fourth Shinobi World War, Naruto somehow managed to rekindle 's extinguishing chakra after the latter unlocked all of the Eight Gates. Naruto's physical abilities were also bolstered to the point where he was able to overwhelm the revived Madara in his Ten-Tails jinchūriki form, forcing him to absorb the entirety of the Shinju.
