Hamura Ōtsutsuki Golem

The giant golem was a creature that resided on the moon alongside Toneri Ōtsutsuki.

Appearance
The golem's body looked to be made out of stone, resembling a giant slug and having a cobra-like veil and enormous arms made out of the same material. The golem didn't seem to have legs, making its movement sluggish. Its face also had a similar structure to that of Hamura Ōtsutsuki's, complete with the horns and six magatama designs, branded on its collarbones, resembling the necklace worn by Hamura himself. In its back, there are some black magatama-shaped protrusions (at least 7) aligned in certain alignment resembling Hagoromo's cloak.

Abilities
The golem was able to fight hand-to-hand, and temporarily overwhelm Kurama, the strongest of the nine tailed beasts. It was durable enough to survive a Tailed Beast Ball launching it into orbit through the moon undamaged. It could also regenerate any damaged piece of its body, making it very difficult to defeat. It was also capable of manipulating the gravitational force to draw meteorites from its surroundings to rain down the moon's surface.

The Last: Naruto the Movie
When Naruto Uzumaki and his team saw the golem emerging from beneath Toneri's castle, he activated his Nine-Tails Chakra Mode and summoned Kurama outside of his body. Kurama and the golem then engaged in a fierce fight. When Toneri was defeated, the golem froze temporarily. It was later able to move again only to punch Kurama, but missed and was quickly defeated by Kurama's Tailed Beast Ball, sending it flying into space.

Trivia

 * The golem was somehow related by Tenseigan's user. It was evidenced by when Toneri awakened his fully matured Tenseigan, the golem somehow activated. It's unknown if the golem was summoned or simply activated by the eye's fully-matured form presence.
