Doujutsu
Sharingan(First Stage Kekkei Genkai):
Literally meaning "Copy Wheel Eye", is a dōjutsu kekkei genkai, which appears in some members of the Uchiha clan. It is one of the Three Great Dōjutsu, along with the Byakugan and the Rinnegan. The Sharingan is also called "Heaven's Eye", because of the many abilities it grants the user. The Sharingan itself consumes the user's chakra while active, although the amount of chakra that the user must exert is so insignificant that they can keep it active constantly if mastered.
Heaven's Eye: The first of the Sharingan's powers is granting the user an incredible clarity of perception, allowing them to pick up on subtle details, being able to read lip movements or mimic something like pencil movements. This skill also gives color to chakra, allowing the wielder to differentiate and easily recognize genjutsu and different forms of chakra and tell if a person is under a genjutsu or not, though not to the same extent as the Byakugan.
As the Sharingan evolves, gaining more tomoe, this ability extends to being able to track fast-moving objects before finally giving some amount of predictive capabilities to the user, allowing them to see the image of an attacker's next move from the slightest muscle tension in their body and counter-attack or dodge without any wasted movement. However, even though the user may be able to see an attack or know it is coming, their body may not always have time to react.
Copy-Wheel; Insight: The Sharingan's most well-known ability, granting the user the ability to copy almost any technique that he or she witnesses, apart from other kekkei genkai techniques. The user can memorize ninjutsu, genjutsu, and taijutsu with near-perfect accuracy, allowing the user to use the techniques as their own, or even modify them to create their own new techniques. In order to reproduce a copied technique, however, one must have the necessary skill or ability to perform them. In addition to physical skill and kekkei genkai techniques, the Sharingan cannot reproduce techniques dependent on other factors, such as summons that the user has not signed a contract with.
Hypnosis: As with other genjutsu, hypnosis cast by the Sharingan is capable of putting an opponent to sleep, inducing paralysis, replaying memories to someone else via genjutsu, or creating various illusions to deceive the individual. The potency of the Sharingan's illusion is dependent on the user's knowledge and skill with implementing genjutsu. That involves suggesting actions and thoughts to the opponent through genjutsu cast by simple eye contact between both parties. Advanced Mangekyou Sharingan users can take the hypnosis ability of a normal Sharingan even further to the point where a powerful summon or even a tailed beast may be controlled. Placing tailed beast or huge summonings under hypnotic influence takes only the Head of the Uchiha's or those who are Kage leveled with Uchiha heritage.

Mangekyou Sharingan Ability(Second Stage Kekkei Genkai):
The Mangekyou Sharingan, noted to be the "heavenly eyes that see the truth of all of creation without obstruction", is an advanced form of the Sharingan that has only been activated by a handful of Uchiha. It is distinguished from a normal Sharingan by its appearance, which changes the form of the tomoe seal to certain variations of pinwheels according to each user. The Mangekyou Sharingan is awakened through the trauma experienced from the death of the person closest to the Sharingan user. With the user normally having to witness or experience this first hand, Uchiha throughout history have killed the person closest to them in order to expedite this process. Over time, use of the Mangekyou Sharingan's techniques deteriorates the user's eyesight to the point of blindness. This can be adverted by taking and transplanting the Mangekyou of another Uchiha — integrating the two pairs of eyes in the process — can the vision be restored, a process that results in the creation of an Eternal Mangekyou Sharingan. It would appear that the tighter the blood ties are between the "donor" and the "receiver", the better it is for compatibility — a sibling for example seems to make the best donor. The time from fusing the donor's Mangekyou with the receiver's Mangekyō to the point of full recovery is at least several days. Not only does this process permanently restore one's eyesight, but it also gives the person even greater increases in power. The Eternal Mangekyō Sharingan also changes form from the original Mangekyō form, to what appears to be a fusion of the wielder's own Mangekyou with the transplanted one.
Tsukuyomi: The Mangekyō Sharingan has the ability of inducing a unique brand of hypnosis; Tsukuyomi, one of the most powerful genjutsu in existence. It is unique to the Uchiha clan and only those with the Mangekyo Sharingan can perform it. It is said to represent the "Spiritual World and Darkness", the power requires eye contact to be performed, trapping the target within an illusion completely under the user's control. Someone advent in the use of this technique is able to alter the perception of time with ease within the genjutsu to make a few seconds seem like many days as a means to torture its target. This results in the victim suffering psychological trauma that incapacitates them for a considerable period of time.
Such a powerful technique is not without its disadvantages however. Due to the complexity of the illusion and the quickness with which it is executed, an enormous amount of chakra is necessary and an added amount of stress is placed on the left eye, damaging it and bringing it one step closer into blindness. Also, it is known that Tsukuyomi can only be broken by another Sharingan user, intervening with a hypnotic genjutsu.
Amaterasu: The jet-black flames of the Amaterasu, said to be "the fires from hell" that are as hot as the sun, ignite at the focus of the user's vision. Though the flames have been stated to be unavoidable, Amaterasu can be avoided with sufficient speed. The flames are capable of burning through mostly anything in their path, even smothering regular fire techniques with ease. Amaterasu is said to never stop burning; even when whatever is caught by the Amaterasu is completely reduced to ash or destroyed, it can still continue burning for seven days and seven nights. It cannot be extinguished with water or any other normal methods. However, the flames burn fairly slowly, sometimes allowing anyone struck by Amaterasu an opportunity to remove whatever clothing or body parts have been caught ablaze. Use of the technique also puts a great deal of strain on the user, usually causing their eyes to bleed and limiting the use of this technique drastically. Said strain further damages the eye of the user, one step closer into blindness.
Susanoo: Also known as the Tempestuous God of Valour, is the third ability granted by the Mangekyō Sharingan to those who awaken the abilities Tsukuyomi — which symbolizes the "darkness of the spiritual world" and Amaterasu — which denotes the "light of the material world". It creates a gigantic, humanoid being that surrounds the user. 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. Like the other techniques granted by the Mangekyō Sharingan, the user's eyes and body are strained while using Susanoo because it consumes a large amount of their chakra. It is described as feeling pain in every cell in one's body which only grows from prolonged use. Susanoo is formed through the materialization of the user's chakra and as such differs in appearance as well as colour between users. Even though it envelopes the user, they can move around within Susanoo freely and use techniques from inside of it, as well as manifest parts of Susanoo — as the situation calls for it.
Despite Susanoo's impressive defensive capabilities, the protection it grants its user is not absolute. The user can be thrown out of the upper half of Susanoo by an enemy manipulating the substance underneath Susanoo. Also, a sufficiently powerful attack will still result in damage, especially during the technique's developmental stages. Susanoo users are also vulnerable to attacks which don't actually deal physical damage to it, such as strong lights and sounds, that can also impair their ability to sustain Susanoo. The users are also still susceptible to such things as sound-based genjutsu.
