Yugito Nii's Jinchūriki Forms

Yugito Nii is the jinchūriki of the Two-Tailed Monster Cat. 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. However, she might not have full control, as she is not one of the four people mentioned by the Kage to do so. She can induce the transformation herself. Her abilities are briefly seen during her battle with Akatsuki.

Initial Tailed Beast Form
Seen very briefly during her transformation into the Two-Tailed Monster Cat, blue flames surround Yugito's body as her hair comes out of it's braid. The powers of this form is unknown, though if it's like Naruto Uzumaki's Jinchūriki Forms's, it grants her enhanced strength and speed.

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 materialize. 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.
