Background
According to Madara Uchiha, the Two-Tails came into being near the end of the waning days of the Sage of the Six Paths' life; to prevent it's resurgence, the Sage split up the demon's chakra of the Ten-Tailed Beast into nine seperate, monsterous constructs of living chakra, which would become known as the 'Tailed Beasts'.

Hidan and Kakuzu arc
Soon after her introduction, Yugito was captured by two Akatsuki members, Hidan and Kakuzu, although it is unknown which was specifically assigned to capture her. Despite luring her two pursuers into a closed space, sealing the exits, and transforming herself into the Two-Tails, Yugito was overpowered and rendered unconscious by the two Akatsuki members. Zetsu later arrived to take her off their hands, and she later died as a result of having the tailed beast extracted from her.

Activity inside Yugito
As the Two-Tails' jinchūriki, Yugito had the ability to transform into the monster cat, giving her access to its strength and its ability to breathe fireballs from its mouth without losing control.
