Profil About Itachi Uchiha

Profil About Itachi UchihaItachi Uchiha is a missing-nin from Konohagakure, and a prominent member of Akatsuki, partnered with Kisame Hoshigaki. He is Sasuke Uchiha's older brother.
Itachi can be translated as "weasel".To some degree of Japanese belief, weasels are considered a harbinger, often signifying ill fortune (possibly a reference to his murder of his family. His surname, Uchiha, is another way of pronouncing uchiwa, or a paper fan, which is actually the Uchiha clan symbol. An uchiwa can be used to fan flames, making the flame hotter, referring to the fact that the Uchiha is a clan of fire-jutsu users.
Itachi is relatively popular among many fans of Naruto, often having ranked in the top ten in Shonen Jump magazine's popularity polls since his introduction. He was first ranked in the third character popularity poll ranked in 11th place. He was ranked 9th place during the fourth popularity poll, and 6th place in the fifth popularity poll. During the sixth, most recent popularity poll, he again was ranked in 11th place.

Early Life

He was praised highly by his father, who saw the family's future in Itachi and neglected his other son-- Itachi's little brother Sasuke. However, during this time Itachi showed great affection towards Sasuke, and even encouraged his father to come to the Academy when Sasuke was enrolled, something their dad had otherwise forgotten, by saying that he would otherwise not come on a mission.
Not much is known about Itachi's childhood, only that at age 4 Itachi had already witnessed countless lives lost due to war, which emotionally traumatized and effected his demeanor. It is also known that he graduated from the ninja academy after only one year. At age 7 he graduated from the Academy and awakened the Sharingan at age 8, passing the Chunin exam at age 10 and becoming ANBU squad leader at age 13.

Personality

He succeeded in killing everyone except Sasuke. He left his little brother alive, telling him:

"Foolish little brother... you can't kill me, your hate's not strong enough... you're not strong enough. That's right, live in shame, run away, and live."

Sasuke has done this, living only to avenge his family and become strong enough to kill Itachi. However, killing Itachi is not going to be easy. Itachi at age seven was already a ninja, at eight had mastered the Sharingan (a special ability of the Uchiha), and at 13 had destroyed an entire tribe. He was able to stand up to Kurenai, Asuma, and Kakashi (all of whom are the highest ranking ninjas, and Kakashi being Sasuke's sensei). He was also able to defeat Orochimaru who is said to be one of the most powerful ninjas of Leaf Village.

Abilities

 Itachi is also noted to be very fast with his techniques and movements, as Kakashi Hatake, an experienced Jonin with the Sharingan, couldn't keep up with his hand signs during their first confrontation in Part I.Even his younger brother Sasuke, who has mastery of the Sharingan, couldn't see him make hand seals during their fight, and he made them while thousands of shiruken were flying through the air towards him, and while he was blocking them all.

 His final technique is Susano'o, which is an ability that manifests as a spectral being resembling a yamabushi surrounding his body. It wields the Totsuka Sword, a spectral sword with the ability to bind what it cuts into an alternate dimension, trapping it in a genjutsu-like state forever, and Yatas Mirror, a shield that can endure intense damage. Zetsu, a fellow Akatsuki member, states that Itachi's mastery of doujutsu combined with Susano'o makes him essentially invincible. Despite his mastery of the Mangekyou Sharingan, Itachi is falling prey to its side effects, as his eyesight is worsening after every activation and he will eventually go blind from its power, and his Sharingan will be forever sealed away.
Itachi also possesses the Mangekyou Sharingan, which not only increases his already great power, but enables him to use some of the most powerful techniques seen in Naruto. With his left eye, he can use Tsukuyomi, which makes him capable of trapping an opponent in an illusionary world where he may seem to torture them for days on end in only a matter of seconds. With his right eye he can use Amaterasu, whereas it allows him to create a black flame that is able to overpower many obstacles and burn everything in its path.
As seen in Ultimate Ninja 2 Itachi doesn't always appear to use shadow clones. When using "Clone Great Explosion" or, as called on UN2 "Shadow Clone: Smash" the clone appears to be a water clone. He also uses a defensive technique called "Shadow Clone: Haze" which summons a clone if Itachi receives a physical attack. He and his clone begin punching their opponent back and forth until the true Itachi finally delivers a strong kick, sending the opponent flying.
