The Mangekyo Sharingan is a powerful form of the Sharingan, a special eye technique used by characters in the Japanese anime and manga series Naruto. The Mangekyo Sharingan grants the user enhanced visual abilities, including powerful genjutsu and the ability to cast unique and powerful techniques called "Mangekyo Sharingan abilities." These abilities vary from user to user and typically come with a high cost, such as deterioration of vision or loss of sanity. It does not provide increased perception in the traditional sense, but rather grants unique and powerful visual abilities.
