Complete Body — Susanoo

The ultimate ability of the Mangekyō Sharingan, accessed from either achieving the Eternal Mangekyō Sharingan or Six Paths Chakra.

Appearance
Complete Body - Susanoo has several consistent features that are apparent in all users. These features include the immense size, which dwarfs all previous forms of Susanoo, the tengu mask with the jewel on the top of the forehead, the samurai-like armor, and the set of second arms on the back of technique. A few users are able to turn the second set of arms into a set of full wings, such as Sasuke Uchiha and Kakashi Hatake have, enabling flight. All Complete Body - Susanoo also possesses a set of Susanoo Swords which are gigantic katanas.

Usage
The Complete Body - Susanoo is a tremendously powerful technique, comparable in power to a Tailed Beast without the latter, its able to easily slice through entire mountains with a single swipe of its sword. Not only that, some versions have the ability to fly, giving it great dexterity. When enhanced by Six Paths Chakra, Complete Body - Susanoo becomes powerful enough to destroy Ten-Tails empowered Chibaku Tensei's.

Above all, the being the ultimate evolution of the Susanoo's 'ultimate defense', Complete Body - Susanoo can take a tremendous amount of punishment before falling. Only the strongest techniques, such as Top Transformed Buddha, Eighty Gods Vacuum Attack, or Six Paths Chakra enhanced Tailed Beast Balls have been able to damage or destroy the technique.

Tailed Beast Containment
As Sasuke Uchiha showed, the Complete-Body Susanoo can be used to contain the chakras of all nine Tailed Beasts, tremendously increasing the technique's power. It gained new weapons in this form, notably Lightning Release arrows and senbons that were strong enough to counter Tailed Beast Balls, with the strongest technique being Indra's Arrow. With it, he's able to overwhelm Naruto Uzumaki's Six Paths Sage Mode Tailed Beast Form, forcing him to gather tremendous amounts of Natural Energy to counter due to prior exhaustion.
