Susanoo

Susanoo is an ability granted to those who awaken the powers of both their Mangekyō Sharingan. It creates a gigantic, humanoid being that surrounds the user and fights on their behalf. 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 force and damages their body over time. With continued mastery of Susanoo, the user can bypass this weakness and can continue to sustain Susanoo with the only concern being their chakra reservoir.

Overview
According to Sasuke Uchiha, if a Sharingan user unlocks two Mangekyō Sharingan powers, one in each eye, known as the, it gives access to the third power, Susanoo. Nevertheless, for a Sharingan user to activate Susanoo, according to Obito Uchiha, is a rarity. Since it is formed through the materialisation of the user's chakra, its abilities, appearance and colour vary among individuals. The user is able to freely move around within Susanoo's body as well as levitate inside of it, and can also leave its body entirely while maintaining it. It is also possible for others to enter Susanoo when allowed by the user. While Susanoo acts as a defence against external attacks, anything coming out of its body will simply phase through it. Susanoo can also be easily reformed in the event it is oblierated by a powerful attack, provided it protected the user from being massively injured and they're still physically capable of reforming it.

Several users of this technique have demonstrated the ability to activate and maintain Susanoo without having their Mangekyō Sharingan active, or even their regular Sharingan. Madara was able to use this technique even without having any eyes.

Weaknesses
As with other techniques granted by the Mangekyō Sharingan, the user's eyes and body are strained while using Susanoo and a large amount of their chakra is consumed. Sasuke described this sensation as feeling pain in every cell in his body, which only increased as Susanoo developed. Because the user is able to freely pass through Susanoo, it is possible for an opponent to forcibly remove them from it; Gaara, for example, was able to drag Madara outside of his Susanoo using the sand under his feet. A sufficiently powerful attack can result in damage being done to Susanoo, especially during the technique's developmental stages, after which the user is left open to attack. Susanoo cannot defend against attacks which do not actually deal physical damage to it, such as strong lights and sounds, sound-based genjutsu and, in the anime, paralysing pollen, all of which can impair the user's ability to sustain Susanoo.

Development
As it develops, Susanoo goes through several different forms, usually gaining additional weaponry in the process. The user can switch between these forms at will or, in the case of the first two stages, leave it in a state between forms. Susanoo's development was best demonstrated while Sasuke was learning how to use the technique, gaining additional forms as his control over it increased. When first activating the technique, the user can only manifest a portion of Susanoo's skeleton, such as a smaller version of its ribcage which, while providing a good defence, can still be fractured, as well as melted. The user can form other parts of the skeletal structure, such as an arm, to interact with their surroundings, or to wield one of Susanoo's weapons. When first forming, Susanoo manifests around the user as an aura.

Eventually, the user is able to form the entirety of Susanoo's skeletal structure. Additional musculature and skin can then form atop Susanoo's bones, progressively completing it until it develops into a fully manifested form in which the vulnerabilities of the skeletal form are largely eliminated. In its next form, this fully humanoid shape is further surrounded by a layer of armour that causes it to resemble a yamabushi. At this stage, it can prevent enemies from reaching the user unless they can get through Susanoo's various layers. Though users of this technique often only form Susanoo's upper half, legs can be manifested to give it a full body, granting it increased mobility. Some users, who have attained perfect mastery over this technique, are capable of stabilising Susanoo's chakra, causing it enter a colossal form known as the.

Itachi's Version
The two powers Itachi unlocked were Tsukuyomi in his left eye, and Amaterasu in his right. His Susanoo is yellow in the manga, whereas in the anime its skeletal and armoured forms are red and its fully manifested form is orange. Itachi's Susanoo has a human-like skeleton with no visible abnormalities. In its fully manifested form, its face is framed by locks of hair, with an appendage on its chin reminiscent of a Pharaoh's false beard. Itachi's Susanoo has two sets of arms, which are conjoined at the elbows; the secondary arms are manifested as required. In its final form, the armour that surrounds Itachi's Susanoo resembles a long-nosed tengu and it wears a pair of magatama earrings.

In its primary left hand, Itachi's Susanoo wields the Yata Mirror, a shield which is endowed with all five nature transformations, allowing it to change its own characteristics depending on the the attack it receives, thus nullifying it. With its right hands it wields the Sword of Totsuka. The sword is a variant of the Sword of Kusanagi, also known as the, and is wielded by Susanoo's primary right hand and sheathed in a sake jar held by its second right hand. It is an ethereal weapon with an enchanted blade capable of sealing anyone it pierces, and can also cut through opponents and objects like a normal blade. Victims of the sword are trapped in a genjutsu-like "world of drunken dreams" for all eternity. Black Zetsu said that the Sword of Totsuka combined with the Yata Mirror essentially made Itachi's Susanoo invincible.

For longer-ranged attacks, Itachi is able to use the powerful Yasaka Magatama, which can be used as three chakra magatama bound together by a single, circular thread and fired as a projectile, or as several magatama strung out on a chakra string, which detach and fire off individually. In the manga, Itachi's Susanoo is also able to wield a sword resembling a curved dagger in its skeletal form.

Sasuke's Version
Sasuke unlocked the two dōjutsu powers of Fire Release at its highest level in both of his eyes, with the power to unleash Amaterasu in his left eye and the power to control those black flames with his right. His Susanoo is purple in colour in the anime. While initially dark blue in the manga, later chapters colour it purple as well. Sasuke's development of Susanoo was marked by intense feelings of hatred; whenever angered by the words or actions of his opponents, Susanoo grew in power. His Susanoo was, accordingly, noted to be much darker in composition compared to Itachi's. In both its skeletal and fully manifested forms, it has a more demonic appearance in contrast to Itachi's, possessing horns, a long appendage on its chin and a malevolent grin. Sasuke's Susanoo can form up to four arms, manifesting the secondary arms as needed. When it first entered its armoured form, the tengu-like layer of armour surrounding it appeared identical to that of Itachi's armoured Susanoo, save for having jagged teeth around its hood. After Sasuke gained the Eternal Mangekyō Sharingan, the layer of armour worn by his Susanoo changed in appearance. The mouth of the armour took on a beak-like shape, its arms gained additional plating and it overall became more ghastly in appearance.

Sasuke's skeletal Susanoo is able to manifest a sword, which it wields in its left hand. In its fully manifested form, his Susanoo wields a bow in its left hand and an orb capable of producing weapons, such as arrows for use with said bow, in its second right hand. In Susanoo's armoured form, its bow grows in size and takes on a more shield-like appearance. After entering its armoured form for the first time, Sasuke's Susanoo demonstrated the ability to manifest an orb of black flames, which it can wield regardless of which stage it is in. Using Blaze Release: Susanoo Kagutsuchi, Sasuke can produce various weapons from the orb, including a blade wielded by Susanoo's primary right hand, which can be used to stab his targets and set them ablaze, and arrows which can be utilised with Susanoo's bow. Sasuke can also produce tomoe-shaped projectiles from the orb to set his opponents on fire from a distance.

By the time of the Fourth Shinobi World War, Sasuke was able to conjure legs for his fully manifested Susanoo and likewise greatly increase its overall size. He was able to use the senjutsu chakra Jūgo generated via Sage Transformation to enhance his Susanoo with natural energy, temporarily creating markings reminiscent of the Cursed Seal of Heaven. Upon first manifesting his stabilised Susanoo, Sasuke was able to shape it into armour for Naruto Uzumaki's Sage Tailed Beast Mode. In that state, it wielded a plated sword which was able to cut through even the famed Sword of Nunoboko. After obtaining the Six Paths Yin Power from Hagoromo Ōtsutsuki and awakening the Rinnegan, the face of his fully manifested Susanoo temporarily changed; holes appeared in its cheeks, and it no longer bore a grin.

After further refining his control over this technique, Sasuke can stabilise Susanoo's chakra to create its "Complete Body" form. In this state, Susanoo is clad in armour akin to a samurai, wearing robes, thick boots and body armour on its shoulders and waist. It has a long tengu nose, two spikes over each eye, a slit stretching across its mouth and three gaps on each of its cheeks as well as one on its chin. Susanoo's secondary arms become wings, making it capable of flight, while retaining small fingers used to hold its blades when not in use. It wields two katana, which were able to slice through satellites formed by Chibaku Tensei with ease. In conjunction with Sasuke's Rinnegan, it was able to block out the light of the Infinite Tsukuyomi. Sasuke is also able to use his Chidori through this form.

Madara's Version
The two powers Madara unlocked to use Susanoo are unknown. Nevertheless, he is still able to use Susanoo, which is blue in colour. It is made up of two entirely different sides that are conjoined along their spine, both of which have a distinct face. The front face has elongated canine teeth in its lower jaw bracket and two tusks growing from said jaw, while the back face has similarly elongated canine teeth in its upper jaw bracket and a single horn protruding from its forehead. It wields a pair of undulating blades, one being held by the right hand of both its sides. Madara's Susanoo is able to manifest a lower half with legs and feet.

Susanoo itself appears to be capable of contributing toward some of Madara's techniques, as it was seen forming hand seals when he drew down two meteorites. It is able to use the powerful Yasaka Magatama as a ranged attack, creating a string of magatama that Madara can fire at his opponents. Madara has shown the ability to combine this technique with the Multiple Wood Release Clone Technique to create a multitude of these ethereal warriors.

Once entering its armoured form, Madara's Susanoo becomes an enormous construct, standing taller than the wreckage of his meteorites. The outer armour, which is fluid in nature and only remotely resembles the usual tengu-like armour, splits down the middle from its forehead down, revealing Susanoo's eyes while obscuring the rest of its face. Its arms gain plating and the secondary set wield its undulating blades. While in this form, the two front hands always appear to be forming the Tiger hand seal.

Madara's mastery over Susanoo allows him to manifest the "Complete Body" form. In this state, its armour becomes more solid and samurai-like, forming robes, pointed shoes and body armour on its shoulders and waist. It gains a long tengu nose and two lines running down from its mouth to its chin area, as well as hair which is tied up at the sides. Its primary arms lose their plating and decrease in size, while its secondary arms extend behind its shoulders as wings. Rather than undulating blades, this form wields a pair of straight katana, which are sheathed by its winged secondary arms and wielded by its primary arms. According to Madara, the offensive power of his Susanoo is comparable to that of a tailed beast. Madara has displayed the ability to equip his stabilised Susanoo onto Kurama to complement their respective abilities.

Indra's Version
The two powers Indra had to unlock Susanoo are unknown. However, as the first user of the Mangekyō Sharingan, Indra attained complete mastery over Susanoo, allowing him to manifest its stabilised "Complete Body" form. In said form, it is clad in armour akin to a samurai, with 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. It wears robes and has body armour on its shoulders.

Kakashi's Version
After receiving Obito's chakra and Sharingan powers, manifesting them in both his own eyes, Kakashi gained access to the two powers of Obito's Kamui — the short-range version in his right eye and the long-range version in his left eye — unlocking the ability to use Susanoo, which he could quickly fully manifest and stabilise into the "Complete Body" form. In this form, his Susanoo has the characteristic tengu nose and is clad in samuraiesque attire, wearing robes, thick boots and body armour on its shoulders and waist. The construct has forehead protector-like plating on its head, two locks of hair falling on either side of its face, a hole in its chin and a vertical mark extending across its left eye, similar to Kakashi's own signature scar. Its secondary set of arms form wings, allowing for flight. His Susanoo can also conjure up a sword. By combining Susanoo with Kamui, Kakashi was able to launch multiple giant shuriken which warped away whatever they hit.

Shisui's Version
In the anime, Shisui gained access to this technique after unlocking Kotoamatsukami in both of his Mangekyō Sharingan. It is green in colour and has a wide mouth with elongated lower canine teeth. The construct has rounded shoulders with blade-like appendages on them as well as on the side of its face and along its forearms. Its right arm wields a drill-like lance that can be used in unison with Shisui's Fire Release to create a vortex of flames. It is also able to unleash a barrage of chakra needles.

Tailed Beast Influence
After absorbing the chakras from all nine tailed beasts using his Susanoo as a vessel like the Demonic Statue of the Outer Path, Sasuke's Susanoo underwent a drastic change. In this new form inside the armour of Susanoo was a giant humanoid construct made of chakra and a tail of lightning chakra. In this form Sasuke was able to create a bow and arrow which are infused with lightning-natured chakra. One arrow was strong enough to counter a senjutsu-enhanced Tailed Beast Ball.

Senjutsu Influence
Sasuke's Susanoo has shown the ability to take on the properties of Jūgo's Sage Transformation, resulting in what Orochimaru referred to as a. In this form, Susanoo has markings similar to Sasuke's Cursed Seal of Heaven.

Weaponry
As users gain more control over Susanoo, they are able to extend their power by forming weapons. Like Susanoo itself, the appearance and abilities of the manifested weapons vary between individuals. Additionally, as Susanoo becomes more powerful, its weapons do so as well.

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 rather than a sword. Itachi demonstrated the ability to manifest this blade while only forming his Susanoo's ribcage and arms. With it, he was able to cut through Kimimaro's bones, which were stated to be harder than tempered steel.
 * Sasuke's Susanoo is capable of utilising a blade resembling a sabre in its skeletal form, which is wielded by its primary left arm. Sasuke was able to use it to cut through several stone pillars with ease.
 * In its fully manifested form, Sasuke's Susanoo is able to generate a blade resembling an Ōdachi from the orb in its second right hand, with which it was capable of cutting through the roots of the tree form of the Ten-Tails.
 * Upon reaching its armoured form, Sasuke's Susanoo gained an orb made of black flames, from which Sasuke is able to forge a blade wielded by his Susanoo's primary right hand.
 * When Sasuke equipped his Susanoo onto Kurama, it wielded a plated sabre which, while enhanced by senjutsu, overpowered the Sword of Nunoboko.
 * Sasuke's Complete Body — Susanoo wields a pair of katana, which it used to cut through the satellites formed by Chibaku Tensei. When not in use, the blades are held by the hands on Susanoo's winged secondary arms.
 * Madara's Susanoo wields distinct, undulating blades, which resemble kris. The blades are held by the right arm of both sides of his Susanoo in its skeletal and fully manifested forms, and Madara can materialise one while only surrounded by his Susanoo's aura. He is able to throw it as a guided projectile. In the anime, Madara was able to manifest swords in all four of his Susanoo's arms; the blades left traces of blue, fire-like chakra in the ground after impacting and could unleash tremendous shockwaves capable of obliterating numerous shinobi in a single strike. When wielded by its armoured form, the blades were shown to be strong enough to block a caught Tailed Beast Ball being pushed against them by Hashirama Senju's Wood Release: Wood Human Technique.
 * In its "Complete Body" form, the blades more closely resemble traditional katana, complete with sheaths. Said sheaths are held by his Susanoo's back, plated arms, while the swords themselves are wielded by its front arms. Madara can use these to cut through a range of mountains in the distance with a single swing. The blades could be partitioned to a Tailed Beast Ball during its formation, giving it cutting power and preventing it from being caught.
 * Kakashi's Complete Body — Susanoo wields a katana in its primary right arm.

Bow
In its fully manifested form, Sasuke's Susanoo is capable of wielding an unusually shaped bow, which manifests on the wrist of its left arm. In its second right hand, his Susanoo holds an orb capable of creating arrows which can be grabbed by Susanoo's front right hand and fired through the bow at such a speed that evading them is nearly impossible. The bow can double as a shield strong enough to withstand attacks capable of shaving away at the terrain in Susanoo's immediate vicinity. The arrows, which are seemingly made with variable thickness based on the user's discretion, travel at a very high velocity and possess considerable piercing power; enough to easily breach a tree created by Wood Release. Even Kakashi Hatake, a ninja noted for his speed supplemented by the Sharingan's keen perception, was unable to dodge the arrows and was instead forced to use Kamui to warp them away. Only Kabuto Yakushi, while utilising the extrasensory capabilities of Sage Mode, has been able to successfully avoid one of these arrows thus far.

When Sasuke's Susanoo enters its armoured form, the bow gains a notable increase in size, more closely resembling a shield. Upon first entering this stage, Sasuke gained access to an orb made up of black flames, which can be manifested in any of his Susanoo's forms. Sasuke later demonstrated the ability to produce arrows made up of black flames from said orb, which can also be used with Susanoo's bow.

After absorbing the chakras from the nine tailed beasts, Sasuke's new Susanoo acquired a longbow made purely of lightning chakra. The lightning arrow fired from said bow was powerful enough to completely counter Naruto's senjutsu-enhanced Tailed Beast Ball Rasenshuriken and Wind Release: Ultra-Big Ball Rasenshuriken simultaneously, as Sasuke claims it to be his most powerful attack.

Shuriken
Akin to the Yasaka Magatama, performing Susanoo can also manifest multiple shuriken, as seen by Kakashi. They take the shape of the user's Mangekyō pattern and while handheld in proportions to Susanoo, their individual size are massive.

Lance
In its full body form, Shisui's Susanoo wields a lance that has a dual function as a drill. It is often used with Shisui's Fire Release techniques to create more damage.

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, 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, a human-like being described in the as having one body with two faces back-to-back, each with its own set of arms and legs.
 * The is one of the, together with the Sword of Kusanagi and the.
 * 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.

Trivia

 * When it was first used by Itachi, Susanoo was shown to have five fingers on each hand. In all subsequent appearances in the manga, Susanoo has six fingers on each hand. However, in the anime, Susanoo always has five fingers.
 * In the anime, the armoured form of Sasuke's Susanoo had a few minor changes: it had straight teeth and was shown wielding a gourd in its secondary right hand instead of an orb, and in its left hand a shield akin to the Yata Mirror, making it nearly identical to Itachi's armoured Susanoo.
 * Rather than a sword made of black flames, the anime rendition of Sasuke's Susanoo instead wields a sword which is capable of igniting those it pierces.
 * Itachi and Sasuke's Susanoo are depicted as different colours in the anime than in the manga. In Itachi's case, his Susanoo was illustrated in the anime before being coloured in the manga.
 * Prior to the completion of Sasuke's Susanoo, its fully manifested form was glimpsed as a shadowy figure in a genjutsu that Sasuke placed C under.
 * Sasuke's fully manifested form of Susanoo bears a great resemblance to Raideen the Brave, one of a number of Yoshiyuki Tomino references in the series (another being the Gundam-derived names of Kakuzu's techniques).
 * Both Itachi and Sasuke's armoured Susanoo's mouth area always appear to face to the right, but the mouth area of Sasuke's new version faces to the left side instead.
 * The Totsuka Sword wielded by Itachi's Susanoo is considered to be a "Sword of Kusanagi", although this has been popularly mistranslated as it being the perfect counter to the Sword of Kusanagi.
 * Shisui's Susanoo resembles the eponymous mecha from the anime Steel Jeeg.
 * During the Sasuke vs. Itachi boss battle in Naruto Shippūden: Ultimate Ninja Storm 2, Susanoo doesn't appear around Itachi, but behind him. However, during his "awakening", Susanoo appears around him in a much smaller form.
 * In Naruto Shippūden: Ultimate Ninja Storm 3, Madara's Susanoo's swords are capable of spinning, giving them a drill-like ability.
 * In the Third Databook, it was stated that Tsukuyomi and Amaterasu were required to unlock Susanoo. However, this was corrected by Sasuke, and Sasuke's explanation was once again verified by Kakashi.
