Tayuya

was the kunoichi of Orochimaru's Sound Four.

Personality
Tayuya was foulmouthed toward most people, especially Jirobo (called him "fatty") as he criticized over it. She didn't think much of Shikamaru Nara as a leader, but as a weak useless rat who ran away when she used her Doki to attack him. Of the Sound Four, Tayuya was the only member to show a sense of morality as she berated Shikamaru for sacrificing his teammates to bring back one person who voluntarily left.

Invasion of Konoha arc
Tayuya made her first appearance with the rest of the Sound Four, erecting a barrier to keep others from interfering in Orochimaru's fight with the Third Hokage. She later escorted Orochimaru when he fled.

Sasuke Retrieval arc
The Sound Four escorts Sasuke Uchiha when he decides to join sides with Orochimaru. When Team Shikamaru caught up with the Sound Four, they managed to take the barrel Sasuke was being carried in from her. While trying to take it back she is confronted by Kimimaro, who threatens to kill her if she doesn't deal with some of the Konoha ninja. She fights Shikamaru, but is repeatedly outmatched by his superior intellect. When she starts relying on brute strength she is almost able to kill him, but Temari arrives and kills her first.

Abilities
Tayuya was the only one of the members of the Sound Four that actually used sound as a weapon; her main weapon was a flute, and with it she could control her Doki. Tayuya was very intelligent and could think of excellent strategies, though not quite on par with Shikamaru. According to Shikamaru, she would probably also "be very good in shogi". She could also perform genjutsu, what she called Demonic Flute: Dream Sound Chain. Her preference for sound-based, long-range combat with her flute made her vulnerable to close-range combat, as the flute was her only weapon.

When in Level 2 cursed seal form, her hair grew longer, her skin turned dark brown, and she grew several horns on her head. She also gained immense strength, which allowed her to overcome even Shikamaru's various shadow jutsu. She claimed to be the second strongest member of the Sound Four, inferior only to Sakon.

Other Media
Tayuya is a playable character in three of the Naruto: Ultimate Ninja, as well as Naruto: The Broken Bond and Naruto: Gekitou Ninja Taisen 4. She also appears as an assist character in Naruto: Ultimate Ninja Storm. Tayuya is the only one of the Sound Four to appear in various Naruto Shippūden ending skits.
