Ten-Tails (Kara)

A tailed beast-like entity, which Jigen referred to as a Ten-Tails, is kept prisoner in an Ōtsutsuki-related site that can only be accessed via space–time ninjutsu. Sasuke Uchiha identified the beast as a juvenile Ten-Tails.

Appearance
The beast largely resembles the "original" Ten-Tails in its first form. While considerably smaller, it is still massive, comparable in size to the nine tailed beasts. It has a large, egg-shaped head with small spikes protruding from the top alongside a single spike on its chin, as well as a large mouth containing human-like teeth and a single eye with black, vein-like markings around it. It appears to have two small arms, as well as multiple tails; though the exact number is unknown, Jigen calling this entity a "Ten-Tails" suggests that it has ten.

Abilities
The beast is shown to possess an immense amount of chakra. Upon absorbing just a fraction of it with his Kāma, Jigen briefly assumed a form that resembled Isshiki Ōtsutsuki, and he later demonstrated the ability to access this form at will. The beast possesses a single eye containing several concentric rings and six tomoe, which Sasuke identified as a Rinnegan.

Kawaki Arc
While investigating Kara and the Ōtsutsuki clan, Sasuke Uchiha arrived at a strange temple where he found holographic images of various Ōtsutsuki clansmen, specifically Kinshiki, Momoshiki, Kaguya, and another unknown member. Underneath the temple, he was shocked to discover a beast resembling the Ten-Tails being pinned down by large black stakes. Moments later, a portal opened and the leader of Kara, Jigen, stepped out and floated down beside the Ten-Tails, which tried to eat him to no avail. Jigen used his Kāma to absorb some of the beast's chakra and briefly assumed the form of the unknown Ōtsutsuki member from the holographic image, much to Sasuke's shock.
