Appearance
The Two-Tails resembles a bakeneko covered in wild blue flames. Its eyes are like an odd-eyed cat, with a right yellow eye and a left green eye, only without pupils.

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 fire without losing much control.

Hidan and Kakuzu arc
Soon after her introduction, Yugito was captured by two Akatsuki members, Hidan and Kakuzu, although it is unknown who 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.
