Yugito Nii's Jinchūriki Forms

Yugito Nii is the jinchūriki of the Two-Tails. Since her childhood, she was placed into a detestable training regime that at the end, allowed her to have great control of her tailed beast. Also, as shown in one of the Shippūuden filler episodes, when Nekobaa asked Yugito for the Two-Tails' paw print, she was able to transform and provide the paw print. However, she might not have full control, as she was not one of the four people mentioned by Danzō Shimura to do so. She can induce the transformation herself. Her abilities are briefly seen during her battle with Akatsuki members Hidan and Kakuzu.

Partial Transformation
Yugito is able to materialise one of her two tails.

Full Two-Tails Form
While transformed, Yugito is completely covered by the chakra of her tailed beast. In this form, her chakra takes the form of a blue flamed two-tailed cat with no pupils in her eyes. With chakra emanating from her, she will hunch over and the Two-Tails itself will materialise. Though small compared to tailed beast forms of other jinchūriki, the Two-Tails still proves a threat. In this form, Yugito is able to emit fiery spectral blasts from the monster cat's mouth. These blasts are very destructive and when coupled with the Two-Tails' strength, the surrounding area can be reduced to rubble.
