Seven Tails
The Seven-Tails (Nanabi) is a tailed beast sealed within Fu from Takigakure. It has been captured, extracted, and sealed by Akatsuki. In the anime, the Seven-Tails is indicated to have been one of the two tailed beasts that Akatsuki captured before the start of Part II. It was later resealed into a revived Fu during the Fourth Shinobi World War.
Background
According to Tobi, the Seven-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 (Banbutsu Sozo) ability to create nine separate, monstrous constructs of living chakra, which would become known as the tailed beasts. The Seven-Tails eventually fell into the possession of Takigakure and was sealed into Fū, but was captured and extracted by Akatsuki.

The Seven-Tails resembles a blue, armoured kabutomushi, with six of its seven tails resembling green insect wings, along with the seventh tail, all growing from the end of its abdomen. The stem of the tail is green but the wings are orange. Its eyes seem to be covered by a knight helmet like skull, it also has spike protrusions on its shoulders, and six legs, three on each side.
Abilities
Not much is known about the Seven-Tails but since it is a tailed beast, it is able to use the Tailed Beast Ball. It also has the ability to fly.
