Kai (Kung Fu Panda)

A towering, muscular, anthropomorphic yak with light gray skin tinged with otherworldly hues, a massive and powerful body, broad shoulders, and incredibly muscular arms. It has two enormous, twisted, flame-like horns with sharp edges and thick bone texture, plus two smaller horns beneath them. A long, black, and unruly mane cascades down its back. Its eyes glow a bright, intense neon green with a menacing expression. It wears an ancient warrior helmet with metallic details, a large pendant of glowing green jade on its chest (stolen chi), thick brown bracers on its forearms, a worn and layered brown leather loincloth, and bandages on its legs. A subtle golden aura surrounds its body. Its expression is fierce and arrogant, its pose an intimidating, powerful villain's demeanor.

He is the main antagonist. He was a warrior and general of an army, which he led alongside his brother-in-arms, Oogway. Kai fought alongside Oogway as best friends, but after Kai learned to steal the chi of others, Oogway banished him to the Spirit Realm. Five hundred years later, he returned to the mortal realm as a Warrior Spirit and sought to steal the chi of all kung fu masters and destroy them all.
He can only steal Chi with his hands, and with his weapons he can only chain or trap the target to make movements with his hands to grab the target's Chi. And the Chi of the Warriors that he has, when he throws them, transforms into those Warriors but in a jade and evil form. The warriors made of Chi only obey Kai, no one else. Kai can put himself in the point of view of the warriors whenever he wants, but he remains vulnerable when he is not in his own point of view.
