Tenshin Nara's Bijuu Forms

Tails One, Three, Four, and Seven: Using his own chakra, Tenshin Nara can freely and quickly form a demon cloak that surrounds his body. Once activated, his canine teeth and nails grow long and sharp. The cloak itself gives Tenshin paws of chakra around his hands and horns on his head. He can also create an additional set of horns on his forearms to use for his Lariat attack. Increae speed and strength.

Seven and Eight Tails: By tapping into the Eight-Tails' chakra reserves, Tenshin can enter "Version 2" transformations. This is done by forming the chakra into a human shape. These transformations are meant to give him an edge in battle without completely releasing the Eight Tails, as that would endanger anyone around him. The version 2 chakra cloak is much darker than version 1 (similar to Naruto's four-tailed form and upwards). Hooves form around his feet, the horns on his head elongate, and a final "chin horn" resembling that of the Eight-tails appears. While in this form Tenshin becomes more muscular, and if necessary can create chakra bones, such as a bull's skull, to increase the strength of his attacks. When struck by Samehada, only the Eight-Tails' chakra is absorbed, so Tenshin reverts to a version 1 form with the same number of tails.

Eight Tailed: While fighting A missing ninja and his team, Tenshin managed to wound the ninja long enough to transform into the Eight-Tails' full form, in which his skin is destroyed in a similar fashion of Naruto when he reaches the fourth tail and above. In this form, he takes on the appearance of the Eight-Tails itself, rather than just a cloak, taking on the appearance of a huge ox-like creature with eight octopus tentacles as its tails, and four horns on his head, one of which is broken. Like his previous transformations, he seems to be in full control of this form, though to what extent is still unknown. He was forbidden to fully transform by his Kazekage due to its immense power. This, however, didn't prevent Tenshinfrom doing so in desperate situations. In this form, he is able to create a huge sphere of chakra in front of his mouth similar to Naruto's Four-Tailed Fox Menacing Ball. Instead of a concentrated ball of chakra, he releases it as a widespread blast causing destruction on a large scale. In part with his control over the Eight-Tails, Tenshin can turn parts of his body into parts of the Eight-Tails body. For example, he can turn his chakra tails into a solid Eight-Tail tentacles.
