Susanoo

**Susanoo** is a gigantic, humanoid avatar made of the user's demonic power which surrounds them and fights on their behalf, that has been handed down throughout all the generations of the Uchiha Clan. It is the strongest ability available to those who have awakened the Mangekyō Sharingan in both eyes.

## **Attributes**

When activated, Susanoo forms around the user and becomes an extension of their will, acting and attacking on their behalf. By default, Susanoo is anchored to its user and they to it: in its less developed forms it will move around with the user; in its more completed forms the user will be suspended within Susanoo, being brought with it as it moves around. This connection allows Susanoo to shield against physical attacks, one that becomes more difficult to penetrate as it is manifested more fully.

Although Susanoo is quite effective as a defence, it is able to distinguish in what it blocks. For example, the user can still perform techniques while within Susanoo and the attacks will pass through it without complications. Others can be brought within Susanoo with the user's permission, and users can likewise choose to leave Susanoo's protective structure. The latter characteristic can be used against the user; if an opponent can bypass Susanoo, however slightly and latch onto them, they can be pulled out of Susanoo. With continued mastery, Susanoo can have increased defensive capabilities even at its ribcage stage.

If it is damaged, Susanoo does not regenerate and it can only be repaired either by advancing it to the next developmental stage or by dispersing it and then forming it anew. Also, Susanoo is also only able to defend against physical attacks, so they are still vulnerable to visual or auditory attacks for example. Additionally, unless the legs of the Susanoo are fully manifested, the user's still vulnerable to attacks from below. Susanoo draws on the user's chakra in large amounts so long as it is active.

Sasuke Uchiha describes the sensation of using Susanoo as feeling pain in every cell in his body, which only increases over time of usage as well as at higher developmental stages. Being a Mangekyō Sharingan-based ability, it also places a strain on the user's eyes the more it is used, however, it is not actually necessary for one's Mangekyō Sharingan to be active while using Susanoo.

## **Development**

As seen with Sasuke's learning how to use it, Susanoo has several developmental stages. Practised users go through all the stages every time they manifest it, layering more advanced stages over earlier ones or stripping them away as is needed; they can choose to stop at any developmental stage. At its simplest level, users only manifest aspects of Susanoo's skeletal structure, such as a ribcage for basic defence or an arm for interacting with the surroundings. Once a full skeleton is made, musculature and, later, skin forms until finally a complete humanoid is shaped. In these early stages, typically only the upper half of Susanoo is materialised, with legs becoming common once it reaches its full humanoid form; however, not all Susanoo users can accomplish the latter feat.

In its next stage, armour forms around the humanoid for further protection, causing it to resemble a yamabushi. In its final stage, users stabilise the demonic power that comprises Susanoo to create a colossal form known as the **Complete Body — Susanoo** (完成体　須佐能乎, *Kanseitai — Susanoo*, *Viz:* Perfect Susanoo, *literally meaning:* Complete Body — He with the ability to help by all means), the ultimate ability of the Mangekyō Sharingan. In this state, Susanoo gains a tengu-like nose, wings for flight, and is clad with robes and ornate armour. This form possesses power comparable to that of a tailed beast or a dragon's, capable of levelling giant mountains and, when enhanced by Six Paths Power, small planetoids with ease.

Users can also channel their own techniques into the Complete Body — Susanoo, as well as shape it around the Nine-Tails to improve its offensive and defensive capabilities. Users are able to mingle the chakra that makes Susanoo with chakra from other sources. Sasuke uses the chakra from his Sage Transformation to make a "Senjutsu Susanoo" (仙術須佐能乎, *literally meaning:* Sage Technique He with the ability to help by all means), with markings of his Cursed Seal of Heaven spreading across it. He later manifests the power of his True Self along with storing Akali Cruachs' within his Susanoo, drastically improving its strength and causing black lightning to emanate from its back.

## **Versions**

Susanoo differs between users, in terms of colour, design, and weaponry. Some features are consistent, however, all Susanoo constructs are deviations of the Japanese tengu, they also have two sets of arms — one of which can form wings as part of its Complete Body form — and six fingers on each of its hands. All Susanoo wield at least one sword.

### **Itachi Uchiha**

Itachi Uchiha's Susanoo was red, its skeletal and armoured forms were red and its humanoid form was orange. In its humanoid form, its face was framed by locks of hair, with an appendage on its chin reminiscent of a Pharaoh's false beard. When its armour was formed, Itachi's Susanoo resembled a long-nosed tengu and it wore a pair of magatama earrings.

Itachi's Susanoo possessed a curved blade that resembled a dagger or tantō. He rarely used this, preferring his Sword of Totsuka, wielded in its primary right hand and sheathed in a sake jar held by its second right hand. The Sword of Totsuka is an ethereal weapon with an enchanted blade that, in addition to standard cutting, can seal anyone it pierces, trapping them in a genjutsu-like "world of drunken dreams" for all eternity.

In its primary left hand, Itachi's Susanoo wielded the Yata Mirror, a shield that can change its nature depending on the attack it receives, thus nullifying it. According to , the simultaneous use of the Sword of Totsuka and the Yata Mirror made Itachi essentially invincible. For long-range attacks, Itachi could use Susanoo to perform Yasaka Magatama.

### **Sasuke Uchiha**

Sasuke Uchiha's Susanoo was initially depicted as a dark shade of blue in the manga, though it is purple in all other medias. Because Sasuke's development has often been marked by intense feelings of hatred and or anger, his Susanoo is noted to be much darker in composition compared to Itachi's. Whereas Itachi's Susanoo appears relatively "normal", Sasuke's possesses demonic horns, a long appendage on its chin, and a malevolent grin. Its armoured form initially appears largely the same as Itachi's save for having jagged teeth around its hood. After Sasuke gains the Eternal Mangekyō Sharingan, however, its appearance changes, the armour's mouth taking on a beak-like shape and generally becoming ghastly-looking. In its Complete Body form, Sasuke's Susanoo has a helmet that features a long tengu nose, two spikes over each eye, a slit stretching across its mouth, three gaps on each of its cheeks and one additional gap on its chin.

Because of his Rinnegan, Sasuke can use the wings of his Complete Body Susanoo to block out the light of the Black Sun. When drawing on the power of his True Self and Akali, the armour of his so-called "True Susanoo" (インドラ須佐能乎, *Indora Susanoo*) is reduced somewhat, exposing the humanoid within. through as well as Great Fireball Technique. This form is capable of generating a sword instead of having it form alongside the Complete Body Susanoo, enabling him to catch opponents off guard. It can be used as a projectile and can explode into massive pillars on lightning large enough to engulf Kurama.

Sasuke's Susanoo has a blade in all its forms: a sabre in its developmental forms; an Ōdachi in its humanoid form, wielded with its second right hand; a pair of katana in its Complete Body form. Its primary weapon, though, is a bow, manifested on the wrist of its left arm; the bow can double as a shield, a function that becomes more visually apparent in its armoured form. Arrows are drawn from an orb held by its primary right hand and can be fired very quickly, such that only Megumi Mitsuzuri, while utilising her natural instincts, has been able to cut one. Weapon properties can be augmented, either with black flames in its armoured form or lightning in its Complete Body state. Sasuke is able to perform techniques through his Susanoo, such as Chidori and Great Fireball Technique.

### **Madara Uchiha**

Madara Uchiha's Susanoo was dark blue in colour. His Susanoo was made up of two entirely different sides that were conjoined along their spine, both of which had a distinct face: the front face had elongated canine teeth in its lower jaw bracket and two tusks growing from said jaw, while the back face had similarly elongated canine teeth in its upper jaw bracket and a single horn protruding from its forehead.

In its armoured form, the usual tengu-like armour splits from its forehead down, revealing Susanoo's eyes while obscuring the rest of its face. Curiously, his armoured Susanoo appeared to always form the Tiger hand seal with its front hands, and was the largest of its variation. In its Complete Body form, its head gained a long tengu nose and two lines running down from its mouth to its chin area, as well as hair which was tied up at the sides.

Madara's Susanoo wielded distinct, undulating blades that resembled kris, held in the right hand of each side. He was able to throw the blades as guided projectiles. In the anime, Madara was able to manifest swords in all four of Susanoo's arms; the blades left traces of blue, fire-like chakra in the ground after impacting and could unleash shockwaves capable of obliterating numerous shinobi in a single strike.

In its Complete Body form, the swords more closely resembled traditional katana, complete with sheaths held in the secondary arms. These swords could cut through mountains across great distances. For long-range attacks, Madara could use Susanoo to perform Yasaka Magatama.

### **Sora Ōtsutsuki**

Sora Ōtsutsuki's Susanoo, named **Origin: Susanoo** (根源・須佐能乎, *Kongen: Susanoo*), is black in colour. In its Complete Body form, it had accentuated eye-holes, a long tengu nose, a spike over each eye, a slit across its mouth and three gaps on each of its cheeks.

## **Influence**

* Similar to other Mangekyō Sharingan abilities, Susanoo was taken from Japanese mythology: Susanoo is the wild god of sea and storms, brother to Amaterasu and Tsukuyomi. He was born from Izanagi washing his nose. Susanoo inherited his father's sword Totsuka no Tsurugi, which Izanagi used to kill his newborn son, Kagu-Tsuchi after his birth burned his mother, Izanami, to death. After his exile for his relentless harassment of Amaterasu, Susanoo redeemed himself when he used Totsuka to slay the serpent Yamata no Orochi and obtained the Sword of Kusanagi from the monster's corpse. He later gave the acquired blade to Amaterasu as a peace offering.
* Susanoo's designs are based on *Tengu* (天狗), well known *yokai* that are associated with the ascetic practice of *shugendō*. In their final forms, the Susanoo are garbed in the attire of *shugendō* practioners, known as *yamabushi*, and wear hoods that resemble tengu masks, with Itachi's and Madara's appearing as long-nosed *Hanataka Tengu* and Sasuke's as a crow-billed *Karasu Tengu*. In Japanese myth, Susanoo produced the fiend Amanozako who is said to have been the progenitor of the Tengu.
* Madara's Susanoo design may be influenced by *Ryomen Sukuna* (両面宿儺), a human-like being described in the *Nihon Shoki* (日本書紀) as having one body with two faces back-to-back, each with its own set of arms and legs.
* The Yata no Kagami (八咫鏡, *literally meaning:* Eight Span Mirror) is one of the Three Imperial Regalia of Japan (三種の神器, *Sanshu no Jingi*), together with the Sword of Kusanagi and the Yasakani no Magatama (八尺瓊曲玉, *literally meaning:* Eight Shaku Curved Jewel).
* Itachi's Susanoo carries the Sword of Totsuka in a gourd. An ethereal weapon inside a gourd could be a reference to the hyōtan-kozō, a gourd spirit from Japanese folklore.
* Susanoo's skeletal stages also resemble the Gashadokuro (餓者髑髏, *literally meaning:* Starving Skeleton), a *yokai* composed of the vengeful souls of fallen soldiers who were not properly buried, taking the form of a skeleton fifteen times the size of a regular person.
