well i should do him because he is on the cover on the book (for now).
Sasuke Uchiha: Sasuke is from the uchiha clan and his parents were murdered by his brother when he was little. his brother, Itachi, let sasuke go and wanted sasuke to hate him. sasuke obviously wants revenge (to kill his brother). so thats his aim. so he lived at his village and wanted to become a ninja and more powerful to kill itachi. he did become a ninja but one day an guy... actually i don't know if he is even human or whatever. well anyway a guy name orochimaru stolen sasuke to have his body and of course naruto (which is sasuke friend) tried to stop them, but failed. now sasuke only WANTS power... so sasuke don't see naruto as his friend anymore. this anime episodes are still coming out so yeah.
