sharingan
A specific eye from Naruto series.
The Sharingan (literally meaning: Copy Wheel Eye, meaning (Viz): Mirror Wheel Eye) is the dōjutsu kekkei genkai of the Uchiha clan that appears selectively among its members.
It is regarded as one of the "Three Great Dōjutsu", the others being the Byakugan and the Rinnegan.
While its powers originated from Kaguya Ōtsutsuki's Rinne Sharingan, its independent form was first manifested by Indra Ōtsutsuki.
