8566 Onua Nuva is a LEGO BIONICLE set released in 2002. He is one of the six Toa Nuva. He is armed with 2 rock cutting quake breakers that can be attached to his feet to become all-terrain treads. He wears the Pakari Nuva, the Nuva Mask of Strength. He has armor on his body and shoulder plates covering his shoulders. In the BIONICLE Universe, he was a Toa Nuva of Earth and had remained silent when the Toa Nuva split up before the Bohrok-Kal were released on Mata Nui. Onua is the strongest Toa Nuva and has a realm similar to Pohatu's. The set is Onua's second appearance in set form.
Mata Nui will need the wisdom and strength of Onua Nuva more than ever in the months to come. Now no place on the island is too far or too dangerous for him to reach, for his quake breakers can be used as high-speed, all-terrain tracks. They can also be used to carve new passages in the earth. Onua Nuva wears the Pakari Nuva, which increases his raw strength to amazing levels.
- Turning the gear on his back will cause his arms to rotate.
- Onua Nuva could transform into a Toa Nuva Kaita by combining Tahu Nuva and Pohatu Nuva with Onua Nuva.
