Prototype Nine Tails

Prototype Nine Tails (九尾, Kyūbi) is one of the Prototype Tailed Beasts. Centuries of being sought after as a tool for war and regarded as a monster that felt no emotions and deserved none in return caused the Nine Tails to hate humanity. It was sealed within Fortress Mao.

Appearence
Prototype Nine Tails is a kitsune with red-orange fur and red eyes, it possesses the upper-body structure of a human, complete with opposable thumbs on its clawed hands. It's size increased tremendously, standing roughly the same height as the Hokage Monument, and Izumogakure.

Personality
The Nine Tails is a cynical and shrewd individual, along with a somewhat twisted sense of humour. It uses "washi" (ワシ) when referring to itself, which is generally used by older men. Kurama is also very prideful, as it believes that a tailed beast's strength is determined by its number of tails, which earned the fox nothing but disapproval from its brethren, especially Prototype Shukaku. Despite its arrogance, the Nine Tails eventually learns not to underestimate its opponents. However, it does easily get annoyed when Mao uses a power other than its own, claiming its jinchūriki needs no other power than its own. Long years of receiving humanity's negative treatment caused the Nine Tails to develop intense hostility and distrust against them, even going as far as proclaiming itself to be the living embodiment of hatred.

Background
Prototype Nine Tails was one of the Prototype Tailed Beasts to be created by Eren's Mother. At one point during the time of the formation of the shinobi villages, When Fortress Sakai and Fortress Mao arrived at the Land of Haro, The Nine Tailed Fox was rampaging in the village and decimating the shinobi forces that tried to repel it. Many shinobi fought the beast, but it defeated and killed all those that stood in front of it. Luckily, the town was saved when Sakai the God of Gunpla Builders sealed the beast within his Brother, Mao.
