Uchiha Itachi: The most Graceful Ninja Of Naruto Anime

 Uchiha Itachi was a prodigy of Konoha's Uchiha clan. He became an international criminal after murdering his entire clan, sparing only sasuke, his younger brother. He joined Akatsuki, where he comes into frequent conflict with Konoha and its ninja, including Sasuke, who seeks to avenge his family. After battling with Sasuke and losing his life to a terminal illness he had been battling prior, it was revealed that Itachi's motivations were more complicated than they seemed and that he only wanted to protect his brother and village, remaining a loyal shinobi of Konoha to the very end.
Itachi was born in Uchiha clan as the eldest son of Uchiha Fugaku and Uchiha Mikoto, and was praised by all as the best of his generation and a genius. Even by the standards of the battle-adept Uchiha clan, Itachi's powers far outshone their own. However, few could understand him. When he was only four, Itachi had already witnessed countless Casualities in the Third Shinobi World War, which emotionally traumatised him and consequently turned him into a pacifist. Itachi spent much of his time researching the history of the village from the writings their ancestors left behind. Because no other child his age cared about the ancestors of the village, Itachi grew up isolated, he didn't even care about being liked or even making friends. During the Nine-Tails' attack on Konoha, Itachi was left alone to take care of his infant brother Sasuke and promised to protect him no matter what. When the Nine-Tails found its way to the Uchiha district, Itachi ran with Sasuke, determined to get him safe from harm.

At age 7, Itachi graduated from the Academy at the top of his class after only one year, mastered the Sharingan at age 8,passed the Chunin Exams at age 10, and, under orders from his father, enrolled in the Anbu half a year later. Itachi was praised highly by Fugaku, his father, who spent most of his time grooming Itachi to inherit the title of leader of the Uchiha, and hence unintentionally neglected his younger son. However, Itachi showed great affection towards his little brother and even encouraged his father to come to the Academy enrollment ceremony for Sasuke, something their father had otherwise forgotten, caught up an important mission that would establish Itachi a place in the Anbu ranks.
