Prototype Seven Tails

Prototype Seven Tails (七尾, Nanabi), is one of the Prototype Tailed Beasts. It was last sealed within Zako of the Land of Haro.

Appearence
The Prototype Seven Tails resembles a blue, armoured kabutomushi (カブトムシ, rhinoceros beetle), 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 helmet-like skull, from inside of which, an orange glow can be seen. It also has spike protrusions on its shoulders and a row of slits on each shoulder, and six legs — three on each side. The legs are also covered by the blue armour, with the exception of extreme ends which are green in colour. It has two pincers on its face, usually covering a mouth full of sharp teeth. On its back behind its head, it has a large two sectioned horned protrusion.

Abilities
The prototype seven tails possesses massive amounts of chakra and can share it with others. Using its wings, it has the ability to fly and can use it to ram its horn into the enemy. It is also able to use the Tailed Beast Ball and insect-based techniques such as the Bug Bite technique as offensives.
