General kai is a supernatural bull who appears as the former brother-in-arms of Master Oogway and (upon his return to the mortal realm) later becomes a powerful evil Spirit Warrior. Thus, he can steal chi from Kung Fu warriors and turn them into Jade Zombies. His scheme is to defeat every Kung Fu master and become all powerful.

Tai lung is a mighty snow leopard who was Shifu's former student, adoptive son and arch-nemesis, Tigress' adoptive older brother, Peng's uncle and was originally trained by Shifu hoping to become the Dragon Warrior. However, when Oogway denied him the Dragon Scroll, Tai Lung ravaged the Valley of Peace, leading him to be defeated and sent away in prison before returning to face the true Dragon Warrior.
