Rinnegan

The Rinnegan (Literally meaning: Saṃsāra Eye) is reputed as the most exalted eyes amongst the Three Great Dōjutsu (San Daidōjutsu, Literally meaning: Three Great Eye Techniques), the others being the Byakugan and the Sharingan. Rinnegan wielders are said to be sent down from the heavens to become either a "God of Creation" who will calm the world's disorder or a "Destroyer" who will reduce everything to nothingness. Rinnegan are characterised by light purple sclerae and irides with a ripple-pattern that spreads over the eyeball.

The Rinnegan grants the wielder a wide range of abilities without any known chakra requirements to keep the eyes active. Certain abilities are only available to the original owner of the Rinnegan, but the possession of even a single transplanted Rinnegan can grant overwhelming power. Rinnegan are able to see chakra, its flow and tenketsu within the body but cannot detect it through obstructions such as smoke bomb. With the Rinnegan, the wielder can master any jutsu as well as all five nature transformations with ease. A Rinnegan user is able to create chakra receivers, into which they can transmit their chakra across long distances. The Rinnegan can also fully decipher the contents of Hagoromo's stone monument. Possessing the Rinnegan grants the user a family of abilities collectively known as the Six Paths Techniques: the gravitational powers of the Deva Path; the menagerie of summons available to the Animal Path; the limitless absorptive potential of the Preta Path; the control over others' souls with the Human Path; the different options of mechanisation of the Asura Path; access to the King of Hell through the Naraka Path. Nagato distributed one of these abilities to each of his Six Paths of Pain — six corpses embedded with chakra receivers. A seventh ability, the Outer Path, is said to allow the user to preside over life and death so that they may revive the dead, summon and control the Demonic Statue of the Outer Path, and manifest chakra chains to bind others. Certain Rinnegan abilities have only been demonstrated by single users: Madara can perform Limbo: Border Jail to create corporeal shadows which are only visible to the Rinnegan; Sasuke's Rinnegan allows him to shift spaces within a certain range of himself.

Wood Release Secret Technique: Nativity of a World of Trees

A technique developed by Hashirama Senju, where the user forces trees to grow on any surface, easily creating a dense forest anywhere they choose. A small plant can grow into a forest in an instant.

By generating chakra, the user manoeuvres it as they see fit for attack and defence; and furthermore, this omnipotent technique even allows them to capture the enemy at the same time. With their tremendous life force, the trees can pierce through earthen walls, and extend their branches at their prey in an instant. Even stating that Konohagakure wouldn't have been established without this technique wouldn't be an exaggeration.

God: Nativity of a World of Trees

After the Infinite Tsukuyomi is activated, the user manipulates the roots of the Shinju, spreading them around the entire world to encase those caught within the genjutsu. By ensnaring all living beings and connecting them to the tree, similar to cocoons, this will keep their now-slumbering bodies alive for all of eternity.

At the same time, this assimilates every victim to the Shinju, regathering the chakra into one location, in order to sprout a new fruit. The chakra can also be collectively used by the user of this technique, as proven when Madara Uchiha's body began to rapidly absorb the chakra of everyone connected to the tree during his transformation into Kaguya Ōtsutsuki. According to Black Zetsu, over an unspecified amount of time, those ensnared by this technique will be converted into White Zetsu. According to Minato Namikaze, simply cutting the victims loose neither wake them up, nor free them from the tree, as another branch will simply form and imprison them once again. Once the Infinite Tsukuyomi is cancelled, the branches, along with any preexisting White Zetsu, wither away and the entrapped people would be freed, assuming they have not already been converted to White Zetsu.

Infinite Tsukuyomi

The Infinite Tsukuyomi (Mugen Tsukuyomi) is a technique which is the key to the Eye of the Moon Plan. The user creates an empty dimension under their control, which can then be filled with the contents of their desire, using the power of the Ten-Tails to do so. While physically tethered and connected to the Demonic Statue of the Outer Path, Madara was able to cast a similar genjutsu, albeit on a smaller scale, using only a standard Sharingan. After doing so, Madara could manipulate the otherwise blank and white world to create anything he wanted, no matter how detailed. To trap every living being in the world within this genjutsu, however, Kaguya's Rinne Sharingan must be reflected off of the moon's surface. In order to do this, with the exception of Kaguya who ate the Shinju's chakra fruit, one must first become the Ten-Tails' jinchūriki. The genjutsu can be cast using the eye that blooms at the top of the Ten-Tails' tree form or the third eye which opens on the jinchūriki's forehead.

Kaguya combined her powers of the Rinne Sharingan and Byakugan to enslave the populace. This technique can also be reflected off the moon, upon the technique's activation, the light from the moon's eye illuminates the entire planet, turning it bright as day and making it impossible to escape. All living things are bathed in its penetrating light and immediately placed under the genjutsu. This causes a reflection of the Rinnegan to appear in their eyes as they are rendered immobile, though their cognitive abilities remain unimpaired. The user can then use the God: Nativity of a World of Trees technique to ensnare the targets, assimilating their life force with that of the Shinju. Once this is done, the person is locked in a permanent genjutsu, in which they experience a dream world based on their individual desires, yet will live forever due to the tree's power, during which the victims are siphoned of their chakra. Once complete, those tethered to the Shinju will become drained of everything they once were and reduced to a shell of their former selves, ultimately becoming White Zetsu — ideal soldiers for Kaguya. Despite the seemingly inescapable nature of this technique, the Infinite Tsukuyomi can be countered through specific means: The user's Rinne Sharingan only reflects off of the moon for a limited period of time after the technique has been activated, allowing those who avoid its light to avoid being trapped within the genjutsu. Using his Rinnegan, Sasuke Uchiha was able to shield himself and his team by covering them with his Susanoo. Believing that this genjutsu was cast using a Rinnegan, Sasuke hypothesised that it can be cancelled by another Rinnegan. Hagoromo Ōtsutsuki confirmed this, but revealed that the chakra of the nine tailed beasts is also required, and that a person with said chakra and a Rinnegan user must form the rat hand seal together, though Sasuke claimed he would be able to cancel the technique alone using the tailed beasts under his control. Upon the technique's cancellation, the roots used to bind the victims wither, as do all remaining White Zetsu.

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.

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.
