Sharingan Spying Creature

This mysterious creature belonged to Shin Uchiha. It had four small limbs and what appeared to be a tail, an askew mouth and a nose. Its single eye featured a fully matured Sharingan. The creature was very stealthy, able to spy at the gate of Konohagakure without being detected. Its vision was linked to Shin Uchiha and his son's, enabling them to notice the movements of their targets. The creature could also act as a verbal communication medium, seen as Shin received orders from his father through it. By taking on the form of Shin's Mangekyō Sharingan, the creature could use a type of space–time ninjutsu, although it is unknown if it possessed this ability itself or if it acted once again as a medium.

The creature was used by Shin Uchiha to notice the departure of Sarada Uchiha from Konohagakure. Upon seeing the vision, one of Shin's clones was ordered to capture Sasuke Uchiha's daughter. A bit later, after the clone clashed with Sarada, Chōchō Akimichi and Naruto, Shin ordered him to withdraw through the creature. Shin's clone and the creature then flew by using space-time ninjutsu.[2] Later, when its master was ready to begin another attack, the creatures teleported him and six copies of Shin to Naruto and Sarada. When the Shin clones betrayed their father, Shin attempted to kidnap Sarada and Chōchō for hostage purposes, ordering the creature to take them. However, Sarada caught sight and punched the creature in the eye, killing it.

Izanami

Izanami is one of the ultimate dōjutsu of the Uchiha clan. It is a genjutsu which affects the target through physical sensations shared between them and the user, instead of affecting the chakra steams of the opponent to perform the illusion. Like its counterpart, in exchange for the temporary ability that it grants the user, the Sharingan with which Izanami is cast is rendered blind and loses its light forever. According to Itachi, this technique and Izanagi form a pair, but unlike the latter, which is a technique capable of altering destiny, Izanami is instead one that decides it. Whilst under the effects of the technique, the target stands motionlessly as the loop of events continually replays inside their mind. Each time a loop is repeated, any physical damage incurred is reset as it were before the start of the loop, although the remains of severed appendages do not disappear. The illusion of the user and anyone they were fighting alongside also have any damage reset as well such as the blindness that comes with Izanami. Despite being able to become consciously aware of their situation and act differently, the victim is unable to significantly alter or escape from the inevitable progression of these events as the illusions they're fighting will also quickly adapt to their changes in order to force the victim to experience the memorised sensations.

However, because this technique was created to reprimand and save the users of Izanagi, the victim is able to escape the infinite loop if they can acknowledge the real results of their actions and in doing so, accept their fate. In the anime, it's shown that there is no other way to undo this technique even by someone who has complete control over their chakra. The illusion of the caster also seems to be sentient as the illusionary Itachi was shown to be shaking his head when Kabuto futilely tried to undo the technique without accepting his fate first. The illusion of the user and anyone they're fighting alongside also repeats their verbal actions such as the illusionary Itachi telling the Illusionary Sasuke not to leave his side, an action Itachi did to Sasuke. The illusion of the user will continuously tell the victim to take a closer look at them and knowledge their mistakes until they do so. According to Itachi, there was a point in time where members of the clan abused the abilities granted by Izanagi, instead simply casting the technique as a means of escaping the undesirable results of their actions. Whilst this resulted in little issue if only one person were using Izanagi, if there were two or more casters, they would begin to fight amongst each other over personally favourable outcomes. Thus, as dōjutsu users were unlikely to succumb to ocular genjutsu, Izanami was created as a method to reprimand such clansmen, as well as save them from their own arrogance. By imprisoning them within an unalterable loop of events, the victim was forced to accept the reality they had created if they ever wished to escape the illusion. However, because of the dangers involved in using a technique with a way out in a real battle, Izanami became classed as a kinjutsu. Like the various techniques used with the Sharingan, this technique is named after a Shintō goddess. In this case, it is Izanami, who, together with her brother and husband Izanagi, created the islands and other deities of Japan. One of the most famous stories about Izanami tells the tale of how Izanagi goes into Yomi, the Japanese underworld, to retrieve her after she died giving birth to the Shintō fire god, Kagutsuchi. In Yomi, he manages to get Izanami and they both try to leave, however, Izanagi was not supposed to look at her before they escape. Right before they reach the exit, Izanagi looks back and sees her in a decayed form. Frightened, Izanagi flees from Yomi and blocks the cave. Izanami curses Izanagi saying that she will kill 1000 people per day. In response, Izanagi says that 1500 people will be born each day. In another variation of the story, it is stated that Izanami told Izanagi to leave, however, he came back while she slept and lit a fire that revealed her decayed form, prompting him to escape out of fright, and barricade her inside with a giant boulder. After his failed attempt to get Izanami, Izanagi washed himself in a stream. As he cleaned his left eye, Amaterasu was born, as he cleaned his right eye, Tsukuyomi was born, and as he cleaned his nose, Susanoo was born.

Izanagi

Izanagi is a genjutsu that is cast on the user instead of others and is the most powerful amongst this type of genjutsu. When activated, the caster removes the boundaries between reality and illusion within their personal space. To a degree this allows the user to control their state of existence, but it is normally active for only the briefest of moments. At the same time, in the anime, a skilled enough user of this technique can expand Izanagi's range beyond one's personal reality, able to affect a whole swath of people during the technique's activation.

While the target remains physically real while fighting, this technique is capable of turning any occurrence including injuries and even death inflicted upon them, while the technique is active, into mere "illusions." Whenever the user receives a fatal injury, he or she automatically fades away as though they were an illusion all along and then returns back to reality; physically real and unscathed. The technique is based on an ability the Sage of the Six Paths had, referred to as "Creation of All Things" (Banbutsu Sōzō). The process he used is explained to have initially involved the administration of imagination, and the spiritual energy which forms the basis of Yin chakra to create shape and form from nothingness. Then, through the application of vitality, and the physical energy which forms the basis of Yang chakra, he would breathe life into the prior form. Thus, a technique with the power to turn imagination into reality was born, known as Izanagi. Izanagi can be used only by those with the genetic traits of the Sage of the Six Paths. The Uchiha, descended from the Sage, are able to perform Izanagi with their Sharingan. Even with such an eye acting as a medium, gaining the power to briefly control reality's flow as the user sees fit comes at a price; one has very limited reserves of time within a single eye for invoking this technique. This technique would normally be used for only the most dire of situations as after the Sharingan with which Izanagi was casted exceeds its limit, the said eye becomes powerless and is rendered blind permanently, with the rare exception that its sight and power can be restored to the said eye by further evolving it into a Rinnegan. For this reason the Uchiha labelled it a kinjutsu. Danzō Shimura, in an effort to make practical use of the technique, had ten Sharingan embedded into his right arm. To use Izanagi to its full potential, users must also have the genetic traits of the Senju, who are also descended from the Sage. Partially for this reason Danzō had some of Hashirama Senju's DNA transplanted into his arm, which extended the time span of each Sharingan's Izanagi to a minute, allowing him to use the technique for up to ten minutes in total, with breaks in between as he deemed necessary. However, because Danzō is not an Uchiha, his chakra levels drop substantially every time a new Sharingan is used to activate the technique. Obito also makes use of Hashirama's DNA but, in contrast to Danzō, he claims to have gained control over Hashirama's DNA and as such, boasts the completed form of Izanagi. Although, there is evidence to this claim, such as the fact he was able to perform it with hand seals with only one hand or no hand seals at all. As with many Sharingan-based techniques, the Izanagi can be implanted into one's Sharingan to trigger the technique even after the user has already died; Madara demonstrated such usage after his actual death, as opposed to merely negating a mortal wound.

Genjutsu: Sharingan

This is simply the generic use of genjutsu as employed by Sharingan wielders. By establishing direct eye contact with the intended opponents, the user can lock them within a genjutsu of their choosing in order to achieve various effects. These effects range from inducing instantaneous, but temporary, unconsciousness in an opponent to forcefully extract any valuable information that they possess controlling their actions or to show memories.

Using his Sharingan, Sasuke stares at his opponent directly in the eyes and they stare back. Then a shadowy figure of himself appears before them forcing them under a genjutsu. An image resembling his Susanoo appears in front of the opponent and grasps them as it begins "assimilating" them into itself. This breaks the opponent's will. Afterwards, the opponent is left incapacitated. Itachi is seen using an illusion that traps the victim in a dark empty space where their body is made of paper that burns from toe to head while the user is watching. The genjutsu will make it harder for the target to move properly. It bears a great resemblance to his Tsukuyomi, though it is used with the regular Sharingan. Obito's Sharingan was able to directly control both tailed beasts and jinchūriki, with his eye power being compared to Kotoamatsukami by Mei Terumī and Ao. Kakashi could use the Sharingan to hypnotise the target, making them make seals at the same time as he did, thus giving the illusion he could see into the future. He was also able to put multiple people to sleep with a single glance with his Sharingan, even shinobi of Anbu calibre. Shisui was able to render people unconscious with a single glance from long distance with his Sharingan. Madara's usage could control the tailed beasts like Kurama, or paralyse a shinobi with a single glance.

Demonic Illusion: Shackling Stakes Technique

Firstly, this technique requires the use of the Genjutsu: Sharingan. The opponent is caught in the illusionary world created by the user, and the victim is tormented with the sensation of having spikes driven through their limbs, taking away their body's freedom.

At the same time, the physical pain accompanying the illusion reveals that the greatest use this technique has is torture. As seen when Itachi used it on Orochimaru, it has been proven that one of genjutsu mastery may use the genjutsu even without eye contact. Orochimaru described this technique as a type of Temporary Paralysis Genjutsu (Kanashibari no Genjutsu).

Coercion Sharingan

With a single glance of the Sharingan, this technique forces a nightmarish genjutsu on the victim, overpowering them and bringing them to their knees.

Even the usually emotionless Sai was deeply affected by this genjutsu.

Demonic Illusion: Mirror Heaven and Earth Change

The user decrypts a genjutsu that has been applied onto them, and casts back a technique with identical effects onto the opponent.

It's a form of illusion reversal, but in order to instantly read through a technique and cast it in return, the Sharingan's power is necessary. As a genjutsu is initially used to confuse the enemy, this technique, which sends it right back to its caster, deals a high amount of mental damage, more than anything else.

Sharingan

The Sharingan (Literally meaning: Copy Wheel Eye, Meaning (Viz): Mirror Wheel Eye) is the dōjutsu kekkei genkai of the Uchiha clan that appears selectively among its members. It is regarded as one of the Three Great Dōjutsu (San Daidōjutsu, Literally meaning: Three Great Eye Techniques), the others being the Byakugan and the Rinnegan. When an Uchiha experiences a powerful emotional condition with regards to a person precious to them, their brain releases a special form of chakra that affects the optic nerves, transforming the eyes into Sharingan; for that reason the Sharingan is described as an "eye that reflects the heart" (Kokoro o utsusu hitomi). Often, as per the Uchiha's so-called "Curse of Hatred", this emotion is a negative one, brought on by stress or loss. The emotion can also be positive, driven by a desire to protect or reunite with a loved one. Assuming that the user is aware they have awakened the Sharingan, they are thereafter able to freely use it. When first awakened each Sharingan usually will have only one tomoe, although in Obito Uchiha's case, he immediately gained two tomoe in each of his eyes. Through training and continued use the Sharingan will develop a second tomoe and then, upon full maturation, a third. All the Sharingan's abilities are available to the user from its earliest stage, but with greater development comes greater proficiency with those abilities. As with any dōjutsu, Sharingan can be transplanted into non-Uchiha. They are unable to deactivate it and its use has a greater chakra demand for them than for actual Uchiha, who need only minimal chakra to keep it active. For these reasons, non-Uchiha tend to cover their Sharingan when they aren't using it in order to conserve chakra. Sharingan that originate from the same Uchiha are still linked to some extent even when wielded by separate users, at times enabling those users to see the same things.

The Sharingan grants the wielder two broad abilities: the "Eye of Insight" (Dōsatsugan) and the "Eye of Hypnotism" (Saimingan). Although the abilities are not literally restricted to certain eyes, Madara Uchiha notes that two Sharingan are required in order to be utilised to their fullest potential. Even within these two categories there may exist several distinct though similar abilities: "Eye of Insight" The user can see chakra, giving it colour in order to distinguish it by its composition and source. Though not as capable in this regard as the Byakugan, it can see chakra through some (but not all) obstructions and detect irregularities in a person's chakra flow, such as those caused by genjutsu influence. The user is granted incredible clarity of perception, enabling them to read lips or mimic something like pencil movements. In combat, this allows them to see fast-moving objects and, once fully developed, offers some amount of predictive capabilities: they can anticipate an opponent's next move based on the slightest muscle tension in their body and act accordingly to dodge or intercept. Although a Sharingan user can see these things, they also need the physical ability to actually act on the visual information. The user is able to copy almost any jutsu they see, memorising ninjutsu, genjutsu, and taijutsu with near-perfect accuracy. They can then either perform that jutsu or modify it to suit their needs, as when Sasuke Uchiha bases his Lion Combo on Rock Lee's Front Lotus. Again, Sharingan users need the requisite abilities before they can mimic a jutsu they have seen, and for that reason they cannot, for example, reproduce kekkei genkai abilities they do not have or nature transformations they haven't learned to perform. "Eye of Hypnotism" The user can perform what is generically called Genjutsu: Sharingan. While there are various manifestations and purposes of the ability, the better known one is to, through eye contact, suggest thoughts and actions to a target, coercing them to divulge information or act in a particular way, potentially without the target's awareness. In extreme cases, the Sharingan user can take complete control of the target's body, forcing them to do exactly as the controller wishes; this control is visually indicated by the Sharingan's design appearing in the target's eye. The Uchiha are particularly infamous for using this ability on the Nine-Tails, and in fact can enter its or another tailed beasts' jinchūriki's subconscious to more precisely control the beast's chakra. Multiple targets can be taken control of in this way, though the more divided the user's attention is, the easier it is for targets to escape this control. While not an ability per se, the Sharingan user can appear as if they are able to "see the future". First, the user must perfectly mimic every move their opponent makes and possibly their thoughts and words through careful observation. Then, they suggest an action to the opponent such as hand seals for a technique that the opponent and Sharingan user already know and copy that. With these things done, the user can complete the action even before the opponent does, possibly using the Sharingan's genjutsu to confuse or delay them. In addition to these abilities there are two actual jutsu that a Sharingan user can perform: Izanagi allows the user to warp reality for a short time, changing reality into illusion and illusion into reality, thus escaping death and rewriting destiny; Izanami traps the victim in an infinite loop disregarding the target's five senses, specifically designed as a reprimand for those who would abuse Izanagi. Use of either ability causes the Sharingan with which it is performed to be blinded afterwards, and for that reason the Uchiha classified them as kinjutsu.

Space–Time Ninjutsu

Space–Time Ninjutsu (Jikūkan Ninjutsu, English TV: Teleportation Ninjutsu or Transportation Techniques, Literally meaning: Space–Time Ninja Techniques) are techniques that allow the users to manipulate the space–time continuum.

By manipulating a specific point of space, the user can warp anything targeted into a dimensional void and teleport it to another location instantaneously. Minato Namikaze, Obito Uchiha, Sasuke Uchiha, Kakashi Hatake, Tobirama Senju and Kaguya Ōtsutsuki are skilled users of space–time ninjutsu. All summoning-based techniques are space–time manipulation related, as they warp the targets through a dimensional void to the summoner's location. Space–Time Ninjutsu allows one to bypass any Barrier Ninjutsu, as barriers only extend over the dimension they are placed upon, which cannot prevent Space–Time Ninjutsu users from escaping to the dimensional void and then back outside of the barrier's confines. It appears that each specific space-time technique has its own unique dimensional void that other techniques cannot normally access. However, a user can synchronise their respective dimension with the other one to gain access to it. To achieve this feat, however, requires much more chakra.
