Sharingan

The Sharingan (写輪眼, lit. Copy Wheel Eye; Viz: Mirror Wheel Eye) is the kekkei genkai dōjutsu of the Uchiha Clan that appears selectively among its members.

## ​Acquisition [ ]

When a wielder of this kekkei genkai 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" (心を写す瞳, Kokoro o utsusu hitomi ). The Sharingan isn't restricted to the Uchiha Clan, as it can be either implanted from an Uchiha to someone else.

## ​Abilities [ ]

When the Sharingan is activated, two powerful abilities unlock: the "Eye of Insight" (洞察眼, Dōsatsugan ) and the "Eye of Hypnotism" (催眠眼, Saimingan ).
"Eye of Insight"
- The user can see chakra , giving it color 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 under a genjutsu .
- The user is granted incredible clarity of perception, enabling them to read lips or mimic anything they have previously seen. Sasuke Uchiha 's Sharingan is extremely developed, being able to even see at a cellular level. 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. They can also read the enemy's hand seals to give them an insight of the performed technique's nature, regardless of the speed of performance, so long as the hands are not physically hidden from view. Although a Sharingan user can see these things, they also need the physical ability to actually act on the visual information. In the anime, it is shown that with advanced enough prowess, via eye contact, the user can even enter the target's mind to look through their memories., and even erase them within a long range for several targets.
- The user is able to copy almost any jutsu they see, memorizing 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 prerequisite 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"
- This eye allows the wielder to perform types of genjutsu that requires the Sharingan. While there are various manifestations within this dōjutsu , the most iconic one is to manipulate thoughts and memories through eye contact, which is an excellent tactic to gain information forcefully. This is also useful for getting someone to 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 infamously used this ability on the tailed beasts, and in fact can enter its or a jinchūriki's subconscious to 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, the Sharingan user can see moves almost before it happens. First, the user must perfectly mimic every move their opponent makes, and in some cases 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, with the Sharingan genjutsu either confusing or delaying them.
