Name:Uchiha
Village:Konoha
Kekkei Genkai Name:Sharingan
Kekkei Genkai Ability:Due to the many abilities it grants the user, the Sharingan is also called "Heaven's Eye" (天眼, Tengan). The Sharingan's abilities consist of two parts: the "Eye of Insight" (洞察眼, Dōsatsugan) and the "Eye of Hypnotism" (催眠眼, Saimingan). The first of the Sharingan's powers is being able to see chakra flow. The Sharingan itself gives colour to chakra, allowing the wielder to differentiate them. They are also able to tell if a person is under a genjutsu because the person's chakra flow would be irregular. Sharingan can see chakra through solid surfaces such as cave pillars.
The Sharingan's second-most prominent ability grants the user an incredible clarity of perception, allowing them to easily recognise genjutsu and different forms of chakra, however it can't see chakra as well as the Byakugan. It also allows the user to pick up on subtle details, enabling them to read lip movements or mimic something like pencil movements. In the anime, the Sharingan is also able to see through thick fog and other vision-impairing screens. 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.
The Sharingan's third and most well-known ability is that it grants the user the ability to copy almost any technique that he or she witnesses, apart from other kekkei genkai techniques. The user can memorise 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, much like Sasuke Uchiha's Lion Combo. In order to reproduce a copied technique, however, one must have the necessary skill or ability to perform them. A prime example is Rock Lee's brand of taijutsu. While Sasuke was able to copy some of Lee's moves, they put a much more significant strain on him since he hadn't trained nearly as much as Lee had. 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.
History:The Uchiha clan (うちは一族, Uchiha Ichizoku) was one of the four noble clans of Konohagakure, and was also reputed to be the village's most powerful clan, producing shinobi that were exceptionally talented and battle-oriented, and in possession of the renowned Sharingan. Together with the Senju clan, they founded Konohagakure.
