Evolution of Kakashi’s Sharingan in Games (2003-2021)

Kakashi received his Sharingan during the Third Shinobi World War from Obito Uchiha, a replacement for the left eye he’d lost shortly beforehand. The Sharingan became his most identifying feature in the years since then, such that he is widely known as “Kakashi of the Sharingan“. With the Sharingan, Kakashi can accurately reproduce any movement he sees, take in a heightened amount of visual information, and perform the Sharingan’s broad category of genjutsu. Because he isn’t an Uchiha, he can’t deactivate the Sharingan and it rapidly drains his chakra whenever he uses it, leaving him bedridden after extended use; as such, he keeps the eye covered when he doesn’t need it in order to prevent this. Despite his handicap, he is still noted to have impressive prowess wielding it, as noted by Itachi Uchiha.
