Literally meaning copy wheel eye, the sharingan is a bloodline limit commonly found in some uchiha clan members. although anyone can use the sharingan its powers work best in the body of an uchiha. The sharingan is able to see the flow of chakra, this enables the user to tell if a person is under a genjutsu (illusion technique) because the persons chakra flow would be irregular. The sharingans second-most prominent ability grants the user an incredible clarity of perception. for example, it allows the beholder to read lip movements, see the steps of a fast moving opponent, or mimic something like pencil movements.
