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 Isshiki. 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 Isshiki, much to Sasuke's shock.
