Background / History

Sasuke grows up as Fugaku’s younger son, overshadowed by his prodigious older brother, Itachi. Nevertheless, he is considered formidable among his Academy peers and attracts enthusiastic support from female classmates 2.

His first documented match against Yi ends in an unexpected defeat. Sasuke offers to let Yi attack first, then launches a Great Fireball that Yi counters with his own. Yi closes the distance and kicks him away before he can react. Sasuke is stunned; Fugaku and many spectators attribute the loss to arrogance or carelessness rather than recognizing Yi’s concealed Sharingan 2.

Before the Uchiha massacre, Itachi negotiates an agreement requiring Yi to protect Sasuke for five years, until graduation. After the massacre, Sasuke and Yi are identified as the two surviving Uchiha children. Yi suspects Sasuke is under even heavier surveillance than he is 3 4.

Appearance

• Popular looks: Academy girls openly call Sasuke handsome and cheer for him during his match against Yi 2.
• Cold expression: Frequently presents an icy or deliberately indifferent demeanor, including during his earliest encounters with Yi 1 2.

Personality

Sasuke is proud, competitive, and dismissive of those he considers weaker. When Yi joins Team 7, he warns him not to become another burden like Naruto, whom he calls “dead last.” He initially refuses to acknowledge enthusiasm for the team’s celebratory ramen outing, claiming he will attend only because he has not eaten breakfast 6.

Yi’s strength repeatedly challenges Sasuke’s self-image. Watching Yi kill two Chūnin and reveal a Three-Tomoe Sharingan leaves him shocked and frustrated. He responds by explicitly vowing to surpass Yi rather than accepting the gap between them 7 8.

His determination to kill Itachi remains firm during his time with Orochimaru. However, he does not kill indiscriminately: Orochimaru berates him for leaving a group of defeated opponents alive, and Sasuke answers that the person he seeks was not among them 41 42.
