Complete Body — Susanoo

Complete Body — Susanoo is the final form of Susanoo and the ultimate ability of the Mangekyō Sharingan. It can only be accessed when the wielder stabilises their construct's chakra.

Appearance
Complete Body — Susanoo have several common features. These include, but are not limited to, reaching a size that dwarfs the landscape, a tengu mask, with a jewel at the top of the forehead containing the user, samurai-esque armor, and a second pair of arms attached to the back. These arms can sometimes function as wings that are capable of flight. Complete Body — Susanoo possess gigantic versions of the various chakra weapons wielded by Susanoo, with the most common being chakra katanas.

However, akin to how each set of Mangekyō have differing designs, all Complete Body — Susanoo have certain unique features (such as the design of the mask) which reflect the user's chakra and features.

Usage
The Complete Body — Susanoo is a powerful technique, possessing power comparable to a Tailed Beast; it is capable of cutting entire mountains with a single sword swipe. It is also versatile as it possesses wings which give it the ability to fly. The Complete Body — Susanoo could destroy multiple Chibaku Tensei created by the jinchūriki of the Ten-Tails, Madara.

Despite its power, people can be comfortably held within its hand. Much like with the other forms of Susanoo, users are able to manifest singular parts of this technique. Certain users have also proven capable of applying their own jutsu to the Complete Body — Susanoo and its weapons.

As the final form of Susanoo, Complete Body — Susanoo can withstand tremendous amounts of damage. Only the strongest techniques, such as Top Transformed Buddha, Eighty Gods Vacuum Attack, or Six Paths Chakra enhanced Tailed Beast Balls have been capable of damaging or destroying it. Rinnegan users are also capable of using it to shield themselves from the light of the Infinite Tsukuyomi.

Tailed Beast Containment
As demonstrated by Sasuke Uchiha, Complete Body — Susanoo can be used to contain the chakra of all nine Tailed Beasts, with Yin-Kurama likening it to the Demonic Statue of the Outer Path. Complete Body — Susanoo gains powerful new weapons in this form, such as Lightning Release senbon that could counter Tailed Beast Balls, as well as Sasuke's strongest technique, Indra's Arrow. With it, he proved capable of overwhelming Naruto Uzumaki's Six Paths-enhanced Tailed Beast Mode. It was only after receiving vast amounts of Natural Energy from Kurama that Naruto was able to match Sasuke.
