Main article: Six Paths Sage Mode
The Six Paths Sage Mode (六道仙人モード, Rikudō Sennin Mōdo) is a state achieved by Naruto when utilising the Six Paths Sage Chakra. In this state, Naruto's physical parameters and sensory capabilities were enhanced. Apart from a lack of pigmentation around his eyes, it looked like his regular Sage Mode. By drawing on the power of the tailed beasts, Naruto enters a second state and dons something similar in appearance to his Tailed Beast Mode cloak. This second state granted Truth-Seeking Balls, further enhanced Naruto's abilities and his Tailed Beast Mode avatar to the point where it was a match for Sasuke's Complete Body - Susanoo.
Six Paths Ten-Tails Coffin Seal
Main article: Six Paths Ten-Tails Coffin Seal
The Six Paths Ten-Tails Coffin Seal (六道十尾柩印, Rikudō Jūbi Kyū In) is a sealing technique performed by Madara and Obito on the Ten-Tails in order to become its jinchūriki. After performing the necessary hand seals whilst in close proximity to the Ten-Tails' body, the beast is absorbed into the user's body. It grants both Uchiha multiple Truth-Seeking Balls, and one half each of Hagoromo's shakujō. As the jinchūriki of the Ten-Tails, both gained an immense increase in their physical capabilities, as well as enhanced regenerative powers and durability, and were able to completely overwhelm their powerful adversaries. Both Madara and Obito gained horns on their forehead, and a white kimono. Their skin turned a pale grey, and their hair became white. Generally speaking, they resembled Hagoromo Ōtsutsuki.
