Abilities
Not much is known about the Two-Tails' power. It has flexible muscles, granting it great speed despite its large size. Its brute strength is enough to initially pummel Kakuzu who had attempted to use brute force to stop its paw forcing him to use his Earth Release: Earth Spear to survive the attacks. It is also able to create a fireballs which were powerful enough to destroy the sewer they were fighting in and the the building above where they were fighting. It is able to use the Tailed Beast Ball.
According to Tobi, the Two-Tails 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 ability to create nine separate, monstrous constructs of living chakra, which would become known as the tailed beasts.
Like the One-Tailed Shukaku, many people believed that the Two-Tails was once a human that turned into a living ghost .The Two-Tails 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 the Two-Tails' power. In the anime, Yugito agreed to have Nekobaa collect a paw print of the Two-Tails 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 the Two-Tails as well as the Eight-Tails, which indicates how long the beasts were associated with the Land of Lightning.
