Onua broke open a nearby lava source to drive them back, applying earth-power to a tactical problem without ceremony.
Before the final descent to MangaiaMangaiaThe hidden stronghold of Teridax beneath the island of Mata Nui, containing Energized Protodermis and connected to the Bohrok Nest., Onua faced his Shadow Toa, a dark reflection of his own elemental nature. Each Toa Mata confronted such a counterpart, and for Onua it took the form of a being shaped, like himself, for patience and the underground.
