Matatabi (Tlhbba)

Matatabi (又旅, Matatabi), more commonly known as the Two-Tails (ニ尾, Nibi)

Background
Matatabi first came into being in the waning days of the Sage of the Six Paths' life; to prevent the Ten-Tails' resurgence, the Sage split up its chakra and used his Creation of All Things (万物創造, Banbutsu Sōzō) ability to create nine separate constructs of living chakra, which would become known as the tailed beasts. Some time after being created, the Sage sat down with all the young tailed beasts and told them that they would always be together even when separated, and that one day they would become one entity again with different names as well as forms than they did then when the time came for them to understand what true power was. Like Shukaku, many people believed that Matatabi was once a human that turned into a living ghost (生霊, ikiryō). Matatabi eventually fell into the possession of Kumogakure and was sealed within Yugito Nii when she was two years old. She was placed into a detestable training program in order to learn to control Matatabi's power. In the anime, Yugito agreed to have Nekobaa collect Matatabi's paw print for the Paw Encyclopaedia. In a cavern behind the Falls of Truth, where jinchūriki learn to control their tailed beasts, there are wall murals of Matatabi and Gyūki, which indicates how long the beasts were associated with the Land of Lightning.

Appearance
Matatabi is a bakeneko that is completely engulfed with wild blue flames. It also has a right yellow eye and a left green eye, similar to an odd-eyed cat without pupils. When forced to transform by Tobi, Matatabi increased in size compared to when Yugito unleashed it. During the Sage of the Six Paths last days on earth, Matatabi had the appearance of an extremely large flaming kitten.
