Itachi Uchiha (うちはイタチ, Uchiha Itachi?) is an S-class criminal and a Konohagakure missing-nin noted even within the Bingo Book (a list of powerful ninja who have been marked for assassination). He is currently partnered with Kisame to capture Naruto. The name "Itachi" means "weasel". In Japanese mythology, weasels are an ill omen, signifying bad luck and death.
Itachi graduated at the top of his Academy class at age 7, had mastered the Sharingan by age 8, became a Chunin at 10 and was previously an ANBU squad leader at the age of 13. He was, until recently, the only known living person who possessed the Mangekyo Sharingan. Itachi has told Sasuke that if Sasuke were to obtain the Mangekyo Sharingan, the people able to use it will total three.
He left Konoha about five years prior to the setting of Naruto, after slaying his whole clan with the exception of Sasuke Uchiha, his little brother. At 11, even Orochimaru feared him. Orochimaru had planned to use Itachi as his next host, but Itachi had become too powerful for even Orochimaru to handle, which is why he turned his attention to Sasuke.
The reason Itachi killed everyone in his clan except for Sasuke remains unclear. When questioned by Sasuke, he replied, "To test my 'utsuwa'." In Japanese, 'utsuwa' (器) can mean "vessel," or "container," but it can also mean "ability," or "tool." In context, Itachi was more than likely referring to his own power, but this cannot be said for certain. Itachi also briefly makes reference to some ultimate purpose behind the Uchiha clan, but what this is has yet to be revealed.
Itachi, especially after slaying his entire clan, appears aloof and nearly emotionless. While Sasuke's flashbacks reveal a somewhat more loving and personable brother, Itachi later implies that this too was all just an act: playing the part of the older brother all to test Sasuke's potential. Despite being the murderer of his entire clan, as well as his closest friend, Itachi does not appear to kill simply for the sake of it, but instead seems to use just enough force to achieve his goals. When Asuma Sarutobi and Kurenai Yuhi stood between him and the way to his goal (Naruto Uzumaki), he did not kill Kurenai when given the chance. Likewise, he could have easily killed Kakashi and Sasuke, but instead chose to torture them with his Mangekyo Sharingan so that they would witness his power. As it stands, the only way for one to avoid the Mangekyo Sharingan is to avoid eye contact, and focus on the feet or body, as mentioned by both Guy and Kakashi. However, even this is not a certain method of evading his techniques, as he can activate a powerful genjutsu merely by pointing at an opponent
