Susanoo (Sigma)

Sigma Uchiha's Susanoo is the version of the Mangekyō Sharingan dōjutsu technique, Susanoo, employed by Sigma Uchiha. Susanoo is formed through the materialization of the user's chakra and as such it may differ in appearance and colour between users. Ryuga's varies on the mood he is in.

Mangekyō Sharingan
Susanoo goes through several development stages as users gain control of it. The various stages are seen while Sigma is learning how to use Susanoo, through his emotions. In its earliest form, users can only manifest some of Susanoo's skeleton. Sigma does this to produce a ribcage that he uses as a defence, though the bones can be broken, melted, or shattered. He also makes an arm to interact with his surroundings on one occasion. Because these skeletal structures do not entirely surround them, users can move around much easier. As users gain additional control, musculature and skin begins to appear on the bones. It grows to its full size and the user is completely surrounded, eliminating the vulnerabilities of the skeletal form. The user can also change the size of it to fit the current situation. Susanoo eventually develops into a "complete" form, with skin, armour and its final arsenal of weapons finally manifesting. It anchors the user to the ground at this stage, preventing opponents from forcibly moving them unless they can get through Susanoo's various layers. In its final form, this fully humanoid form is surrounded by a secondary layer of armour that causes Susanoo to resemble a yamabushi.

Other than its ability to partially manifest to fit the situation, Ryun's Susanoo can be kept activated longer, because it drains his chakra less substantially due to his mastery of it. Sigma's incomplete version forms the spirit with skeletal muscles for attacking. He is also able to combine the technique with Amaterasu to further increase his defensive power by making it impossible to touch Susanoo without being ignited.

Sigma's incomplete version has a more Pharaoh-like appearance, it has a very round head, with a box-like design around it's eyes and nose area, it also has a short spike-like protrusion coming from the bottom of it's chin, similar to a Pharaoh's mask. It wields a chakra spear in its right hand capable of easily shattering stone pillars. His incomplete version once looked similar in form to a fox, complete with ten tail-like protrusions. After being enraged by Ibitsu's story of Danzō, who had killed his brother as an apparent peace offering to another nation, Ryun's Susanoo changed into the more common, humanoid form, and later, after the formation of Tsukiakari, he is able to produce a fully manifested Susanoo, complete with flesh and armor. Susanoo may feed on it's user's emotions to become stronger.

Unseen in others' versions, Sigma's Susanoo possesses a complete body, including a lower half and legs, which are visible when it emerges from the ground, as well as two entirely different sides that are conjoined along their spine, each with a distinct pair of arms and a unique face. One of these faces has elongated canine teeth in its lower jaw bracket and two tusks growing from said jaw. The other has similarly elongated canine teeth in its upper jaw bracket instead, as well as a single horn protruding from its forehead. When emerged from the ground, its feet, which have six toes each, face towards the side with the elongated lower teeth. Madara has also demonstrated the ability to float inside of Susanoo when it is fully emerged from the ground.

Sword
Because Sigma is advanced in wielding the Samehada, his Susanoo has too grown the ability to wield it. Just as the original samehada, the Susanoo version also inflicts damage through shedding and shaving. Also containing the abilities to absorb chakra, and literally slice through an opponents techniques.

Samehada
Since using Samehada for so long, Sigma's Susanoo has too created his own chakra version of the Samehada. Just as the original Samahada, the Susanoo's also can literally rip through jutsu. Though unlike Sigma, his Susanoo has the ability to merge with the Samehada, and take on features as well as abilities that Kisame did.
