Ongo is the spirit of wood and destruction. Thousands of years ago, he was engaged to the water spirit Rongo, but then the evil inside of him awakened. He then went on a vicious rampage of destruction in the heart of New Guinea, only to be stopped by the beautiful flower spirit Mii, who sacrificed herself to imprison him. Ongo's powers include being able to summon anything through wood, and as the destroyer he can fire bolts of energy out of his mouth as well as his hands, and extend his claws into long blades.
