Yagura's Jinchūriki Forms

Yagura is the jinchūriki of the Three-Tails. Not much is known about him or his tailed beast, but Yagura was one of the few people mentioned by Danzō Shimura to have full control over their respective beast. However, when Akatsuki went after the beast, it was found in the wild for undisclosed reasons. During the events of the Fourth Shinobi World War, Yagura was resurrected and made into a jinchūriki once again, yet the Eight-Tails remarked that his tailed beast felt "different".

Version 2
Whilst resurrected, Yagura displayed the ability to enter a "Version 2" form, by moulding the Three-Tails' chakra into a human-like shape around himself. When entering into this form, the sudden increase in chakra was such that it instantly vaporised Killer B's ink clone, which had immobilised him at the time.

In addition to forming a dark chakra cloak around his entire body, he also gained the characteristic carapace of the Three-Tails on his back, as well as numerous protrusions on his face. With the power granted by this form, Yagura not only manifests all of his beast's three tails, but also becomes able to create coral on direct contact with an object, which continues to grow and eventual restricts the target's movement.

Partial Transformation
After being resurrected, Yagura demonstrated the ability to manifest one of the beast's tails.

Full Three-Tails Form
During the confrontation to capture Naruto Uzumaki and Killer B, Tobi forcefully transformed the revived Yagura into his full Three-Tails form. In this form, he takes on the appearance of Three-Tails itself, potentially allowing him to manipulate the full extent of the beast's considerable powers.
