Kakashi's Sharingan
Kakashi was married to an uchiha member and was a diligent and hard working ninja. During a war
both kakashi
and his wife lost eyes (thus the scar over his eye) however kakashi's wife was mortally injured, but was saved (most probabily by a jounin, who then contacted medical nins) upon hearing about the injury sustained by kakashi,
her last wish was to give him her eye. as she was dying anyway, the medical nin perform the operation and kakashi gets a sharingan eye.
