Yugito Nii's Jinchūriki Forms

Yugito Nii is a kunoichi from Kumogakure, and the Jinchūriki of the Two-Tailed Demon Cat. She seems to be in great controll of her Tailed Beast as she can induce the transformation herself.

Two-Tailed Transformation
After luring Akatsuki members Hidan and Kakuzu to a secluded area, Yugito fought the duo by tapping into the demon cat's powers.

While transformed is Yugito completly covered by the chakra of her Tailed Beast. In this form her chakra takes the form of a cat like Nekomata, shaped by a firery blue chakra, with no pupils in her eyes.

Also Yugito has an incredible control of her Tailed Beast, being able to take its form willingly, and use its abilities, such as fire breathing. However it can speculated which degree of controll she has, considering that she did not only blow up all of the escape routes to capture Hidan and Kakuzu, but also because she does not have full controll of herself in this form
