Susanoo

Susanoo is the third ability granted by the Mangekyō Sharingan to those who awaken the abilities of Tsukuyomi. It creates a gigantic, humanoid being that surrounds the user. As one of the strongest techniques granted to those that have acquired the Mangekyō Sharingan, it is the user's guardian deity, but at the same time, it consumes the user's life.

Susanoo is formed through the materialisation of the user's chakra and as such differs in appearance as well as colour between users. Even though it envelopes the user, they can move around within Susanoo freely and use techniques from inside of it ,as well as parts of Susanoo, if the user calls for it.
Susanoo has an impressive defense and protection, but it's not absolute. The user can be thrown apart from his susanoo. For example, Gaara used his sand to pull out Madara from his Susanoo.
Susanoo has a powerful attack too.The only known ways to attack the user while Susanoo is active is either to draw the wielder out of the technique and then attack, bind and restrict its movements, or to break the defence with overwhelming force. Susanoo users are also vulnerable to attacks which don't actually deal physical damage to it, such as strong lights and sounds. The users are also still succeptible to such things as sound-based genjutsu.


Stages

In its earliest form, users can only manifest some of Susanoo's skeleton.

As users gain additional control, musculature and skin begins to appear atop of its bones, which progressively complete the full skeletal structure.




When Susanoo's growth is fully matured, the user is completely surrounded, and the vulnerabilities of the skeletal form finally eliminated.

Weapon

Sword

All known users of Susanoo are able to manifest at least one sword for the ethereal warrior to wield. Despite their variations, each sword is extremely effective, and in the case of some users, the swords evolve along with Susanoo.

• Itachi's Susanoo wielded a blade which was curved in nature and resembled a dagger or tantō. With it, he was able to cut through Kimimaro's bones.
• Sasuke's Susanoo wielded a blade resembling a sabre, wielded by its primary left arm. Sasuke was able to use it to cut through several stone pillars with ease. Upon reaching its final form, the composition of the chakra orb held by the secondary right arm of Sasuke's Susanoo changed to that of Amaterasu's black flames.
• Madara's Susanoo has two blades, which resembled kris. When Madara's Susanoo entered its final form, the blades increased in size. They were shown to be strong enough to block a caught Tailed Beast Ball being pushed against them by Hashirama Senju's wood golem.

Bow

In its completed state, Sasuke's Susanoo is capable of wielding an unusually shaped bow, which manifests on its left arm. In its second right hand, his Susanoo holds an orb than can create arrows which can be grabbed by Susanoo's front right hand and fired through the bow at such a speed and the chance of evading them is nearly impossible. The bow can also double as a shield. When Sasuke's Susanoo enters its final stage, the bow gains a notable increase in size, more closely resembling a shield.
