Mangekyou Sharingan 

Mangekyou Sharingan is translated as Kaleidoscope Copy Wheel Eye. It is a higher form of the Uchiha clan's sharingan. The basic sharingan will enable the user to memorize any technique that it has been a witness to including ninjutsu, genjutsu, and taijutsu techniques it can also enable the user to see through and illusionary technique. With the Mangekyou Sharingan activated, one major advantage is to be able to use the three most powerful jutsu possible, tsukuyomi, amaterasu, and susanoo. The disadvantage of the Mangekyou Sharingan is, it causes the deterioration of the eyes.

Secret of the Mangekyou Sharingan 

The Mangekyou Sharingan (literally Kaleidoscope Copy Wheel Eye in Japanese) is the 4th and highest level of the Uchiha clan's Sharingan (a technique from the wonderful anime, "Naruto"). Aquiring it signifies complete mastery of the Sharingan, which allows usage to techniques such as Amaterasu and Tsukiyomi. The secret of the Mangekyou Sharingan is that only those from the Uchiha clan who have achieved the 3rd level of Sharingan (3 teardrops in both eyes), and have killed their best friend, may use it. So far in the Naurto manga, Uchiha Itachi is the only one who has been revealed that has achieved such a level.

"If you open your eyes to the truth, including me, the number of people who can handle/deal with the Mangekyou Sharingan will have become three." - Uchiha Itachi to Uchiha Sasuke
