Chōmei

Chōmei resembles a blue, armoured kabutomushi (カブトムシ, rhinoceros beetle), with six of its seven tails resembling green insect wings, along with an actual 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 with three parts on its face, covering a mouth full of sharp teeth. On its back behind its head, it has a large two sectioned horned protrusion. During the last remaining days of the Sage of Six Paths, Chōmei was just in its larval stage of development, was completely green aside from its tails which were a lighter shade of green, having seven full tails instead of wings, and red eyes.

Chōmei and the tailed beasts first came into being in the waning days of Hagoromo Ōtsutsuki, who used his Creation of All Things Technique to divide the Ten-Tails' chakra into nine separate bodies and giving each a name. Some time after being created, the Sage explained to the young tailed beasts that a link existed between them despite their separation. He also foretold of a day when they would be brought together again - though not as they were - and that at that time someone would emerge to show them what true power is. In the anime, before his death, Hagoromo sent Chōmei to live in a temple built for the purpose of protecting it in a closed forest region covered by mosses. At some point in the past, Chōmei became affiliated with Takigakure, making it the only tailed beast known not to belong to Five Great Shinobi Countries. In the anime, this feat is attributed to the village's reputation of frequently producing skilled jōnin. Decades later, the tailed beast would end up being sealed within Fū.
