Sasuke was born into the uchiha clan about the same year as naruto. Sasuke was very envious of his older brother Itachi; the uchiha clan's pride and joy. He tried so hard to someday surpass him. His brother then commited paricide. Every last Uchiha member was slaughtered. He tortured sasuke a little bit with his newly acheived Mangekyo Sharingan. He then told sasuke, "If you want to kill me, try settling on... hating me, resenting me, run like the coward you are and live, live without honor..."he then left. Sasuke never truly mentally recovered from the mangekyo's pain. he decided that even if it meant falling to darkness, he would have his revenge! He then joined ninja squad seven with naruto and sakura. During the mission to protect Tazuna the bridge-builder, Sasuke finally opened the sharingan for the first time in his life. During the Chuunin Exams, he mastered the Chidori but was cursed. He then left Konoha to join Orochimaru. Three years later, he learned unbelievable new jutsu and killed orochimaru. He then started a team known as "Hebi" (hebi means snake). His team consisted of Momochi Zabuza's former apprentice Suigetsu, one of the wardens of Orochimaru's prisons; Karin, and the first ninja to ever gain the curse mark but has wild urges to kill; Juugo. They set out to kill Itachi!
