G`est~zho~el` at the Romanticology...........

Sasuke's early childhood, as told over the course of Naruto manga volume twenty-five, was spent living in the shadow of his older brother, Itachi Uchiha. As a natural prodigy of the Uchiha clan, Itachi was the pride of their family. In an effort to win some recognition for himself, Sasuke trained diligently to win some of his parents' attention, though he was never able to surpass the milestones set in place by his brother.[18] As the years went by only Itachi would acknowledge Sasuke's accomplishments and treat him as part of the family, filling the role of a loving older brother.[19] In time, Itachi began to distance himself from the clan and fell out of his family's confidence. Because of this, the Uchiha began to look to Sasuke as the new future for the clan, and he finally began to receive the attention he had craved.[20]


Personality
Sasuke as he appears in Part II.

When first introduced during his assignment to Team 7, Sasuke displays a great indifference to his teammates. Feeling that his abilities are far superior to their own, he is unwilling to cooperate with Naruto Uzumaki or Sakura Haruno, as doing so would do nothing to help him kill Itachi. These perceptions are quickly proven wrong, for despite their failings, Sakura is an excellent source of information and competition with Naruto acts as an effective way to get stronger. While he retains a confidence in himself throughout the series, Sasuke increasingly relies on his friends over the course of Part I. As he starts to get close to others he also begins to risk his own life to save them, even though his death would leave him unable to gain vengeance on Itachi.

Abilities
Sasuke in cursed seal level two form using the Chidori.

Sasuke has always been able to grasp most ninja abilities with ease. When Naruto begins Sasuke is highly proficient with the Uchiha clan's signature fire-breathing and weapon-based techniques, talents he continues to hone throughout the series. Of the abilities gained through his Uchiha lineage, Sasuke most commonly uses the Sharingan, an ability manifested through the eyes, that grants him a variety of advantages. Sasuke's Sharingan develops for the duration of Part I, first only allowing him to track fast-moving objects and culminating with his ability to predict the movements of others. In Part II he starts to use his Sharingan to cast illusions, allowing him to manipulate and confuse others. Sasuke's Sharingan reaches its peak after Itachi's death; through the death of the person closest to him, Sasuke awakens his own Mangekyo Sharingan, granting him his brother's Amaterasu fire technique as well as the ability to dispel it.
