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 Fū 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 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.

Appearance
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.

Influence
The is among the largest of beetles found in the world. They are also among the strongest animals on the planet in relation to their own size. Its penchant for fighting other males of the species has made them a popular gambling subject in Asia. Beetles are characterized by a hard exoskeleton and fore-wings, which creates a flexible armoured defence. The fore-wings are not used for flight, but tend to cover the hind part of the body and protect the second pair of wings that are used for that purpose. It is also frequently depicted in popular media as a common cartoon character for various uses.
