Kakashi has a strong resemblance to his father, so much so that they are sometimes mistaken for each other. [40] He has spiky silver hair often oriented to his left-side, dark grey eyes (black in several instances), and typically a relaxed and lazy expression. During the Third Shinobi World War, his left eye was damaged, leaving a vertical scar from the injury. The eye was shortly afterwards replaced with a Sharingan, which he covers with his forehead protector when he isn't using it.
