This is the rare Sharingan Mangekyou form which only appears in a few Uchiha members. Uchiha Itachi was able to master this form during the period he killed his clan. In this form Itachi is able to use the Amaterasu and Tsukuyomi Doujutsu techniques. The great hero Itachi gave these eyes and the abilities that come with them to his younger brother Sasuke.
