Not All Users of the Mangekyo Sharingan Have the Same Abilities This ability allows users to trap their opponents within a genjutsu much more easily than the average shinobi in order to more easily escape from an opponent's genjutsu. The Eye of Hypnotism, however, as the name suggests, is based on genjutsu. During the 'Chunin Exam' arc, Sasuke also utilized this ability to perfectly copy the movements of another genin during the written test, allowing him to cheat successfully. Kakashi Hatake used this ability so much he was given the nickname, 'Copy Ninja,' due to his tendency to utilize the Sharingan to copy his opponent's jutsu. The original Sharingan can be divided into two separate abilities: 'The Eye of Insight' and 'The Eye of Hypnotism.' The Eye of Insight essentially allows the Sharingan user to see chakra and perceive visual input at a minute level. Kishimoto, who is well known for his ability to retcon, likely did not know quite how far he would develop the Sharingan's abilities at the beginning of the series. Instead, he probably intended for the exact opposite, as the original abilities of the ocular jutsu were far more subtle than its Mangekyo counterpart. The literal translation for the Sharingan is 'Copy Wheel Eye.' When the Sharingan was first revealed in Naruto, its abilities were far less over-powered than they were by the story's end.
