Sharingan

The Sharingan is the dōjutsu kekkei genkai of the Uchiha clan that appears selectively among its members. 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". Often, as per the Uchiha's so-called "Curse of Hatred", this emotion is mostly consists of a negative one, brought on by stress or loss. But nevertheless, a positive emotion, driven by a desire to protect or reunite with a loved one, can be just as effective to active this hidden power. Those trained in the Sharingan gain great visual prowess that subsequently grants them great mental and physical power. Look into their intense red gaze and it’s already too late. The first time it manifests itself in uchiha members is always related to a great emotional depression linked to a loved one, such as family members or close friends by whom the Shinobi targeted by the Sharingan manifestation nurtures strong ties. For members outside the Uchiha Clan, obtaining this Kekkei Genkai naturally is simply impossible, with the only method, being the one of Sharingan Implantation.
