Sharingan and Mangekyou sharingan

Sharingan

Sharingan is a special type of pupil condition that naturally occurs in all members of the Uchiha clan, though not all of them gain the ability to use it. Itachi hinted at some dark purpose behind the Sharingan end, in whom he and Sasuke know it, but the series has been to reveal exactly what the purpose of it. Sharingan similar to the Byakugan, but it gives the wearer different abilities and different sense.Key capabilities of the most famous of the Sharingan is to memorize any technique ever witnessed. Can memorize ninjutsu, genjutsu, and taijutsu with perfect, making the wearer can use the techniques as his own. To mimic jutsu (stance), however, he must have the ability or the skills needed to implement them. An example is Rock Lee's Taijutsu belong. When Sasuke was able to replicate some of Lee's moves, they put the attention on him because he has notnever trained as hard as Lee. In addition to physical ability, the Sharingan does not allow the user to use other kekkei genkai since the Sharingan user does not have the same genetic trait. Moreover, Sharingan users can not summon a creature that has not made a contract with him.Sharingan also gives users the ability to perceive something terrific, allowing them to see fast-moving objects with ease and even predict the next move of the object. The ability to see and predict the movement largely based on the ability of individuals, for users who are not proficient will find it difficult to see fast-moving objects. Sharingan eye can see everything except the opponents of the fastest, even if the user can not move at the same speed. This ability is also pretty great to deal with genjutsu, depending on the ability of the wearer, and the ability to observe the movement and flow of chakra, but not as clear as the Byakugan. Moreover, the Sharingan gives the wearer the power menganilisis outstanding, let them instinctively take visual clues to mudah.Salah one instance, Kakashi must first shut his eyes to avoid accidentally reading Naruto's lip movements'S ending when she would read one of the books Icha Icha Paradise belongs to Kakashi. Sasuke was also able to cheat on the test answers of others by looking at their pencil movements during the Chunin Exam.Finally, the Sharingan was able to hypnotize involving suggestion and action to the opponent. When used in conjunction with other aspects of the Sharingan, can make the wearer can mimic each opponent's movements flawlessly, even before they do, making it appear as if the wearer can see the future.Sharingan does not automatically appear from birth; instead, it will usually appear when the user in a state of danger, where the power of the Sharingan could save him. After this first appearance, the user can then use the Sharingan any time he wants. (In connection with this, Kakashi Sharingan can not be disabled, and he closed his eyes to conserve chakra.) Power of the Sharingan can be seen by the number of tomoe in the eye, known as the "tomoe seal". Rarely has a number of tomoe Sharingan users are different in each eye. For example, Sasuke's Sharingan initially had two tomoe in one eye and one in the other eye. When his first regular activation, has increased to two tomoe in each eye. He increase it to three in each eye during his battle with Naruto at the Valley of the End. A full Sharingan has three tomoe in each eye.It is possible to transplant Sharingan eyes to someone, it's based on the death of his friend Kakashi and Obito Uchiha. However, transplanted eyes do not work properly if not of the Uchiha clan, causing more strain on the wearer, for example, is too long to use Sharingan Kakashi him unconscious. Uchiha clan members are not burdened with this weakness; while activating Sharingan will consume some chakra, consumption is very small so it is not very meaningful. Itachi does not seem particularly problematic keep Sharingan remains active constantly.Characters that have a Sharingan is Uchiha Sasuke, and Kakashi Hatake. Kakashi eye is given by Obito Uchiha, one of his colleagues in the army of ninja. Obito was killed in battle against the Rock shinobi disguise. In this battle, Kakashi lost his left eye when attacked. At the end of the battle, one of the right side of Obito's body wedged under a large rock, and the last thing he does is ask for Rin, a medical ninja, to take his left eye and implant into the eye holes Kakashi, Kakashi finally able to use the Sharingan though does not have Uchiha blood . This is why only the left eye only the Sharingan eye. 
Mangekyou Sharingan

Mangekyou Sharingan Sharingan is the highest level. Sharingan Mangekyou Sharingan looks different from usual, it will change the shape Sharingan tomoe seal. However, unlike the Sharingan, there are differences tomoe form for each wearer, Kakashi's version is very different to that of Itachi. Those who have the potential to obtain it must make a great sacrifice to obtain it according to Itachi, they must kill his best friend. In fact Itachi got this way, but all the people closest Kakashi long dead before the series started, so how did he get the Mangekyou Sharingan remains unknown. Based on the lines in the comic, making use of the Mangekyou Sharingan users deteriorating eyesight and even blindness.Throughout the history of the uchiha clan, only a few people awaken Mangekyou Sharingan bias. Currently, the only two people who can use the Mangekyou Sharingan, Itachi and Kakashi are. According to Itachi, if his younger brother Sasuke roused, the number of people using the Mangekyou Sharingan bias (including himself) to three. Itachi stated that there are other users Mangekyou Sharingan; however, Itachi used the word "atsukau" which can mean "handle" or "handled", which could also mean that only three people left who can get the Mangekyou sharingan. Itachi had slaughtered the entire Uchiha clan members, this statement is based on the fact that Kakashi, Sasuke and Itachi are known to be living with Sharingan eyes, so no one can potentially get. But there is the reality turns out Tobi is a Uchiha clan member (Obito Uchiha)
