8690 Toa Onua is a BIONICLE set released in July 2008. He is one of the Mistika. It contains Toa Onua in his adaptive armour form, with jet rockets, a Nynrah Ghostblaster with a laser on it used for targeting, a multi-resistant shield, wings, and the Mask of Strength. He was shown combining with 8946 Photok for extra power, but this was just to advertise the connection feature, and was never shown in the story. He is a Toa of Earth. The set is also included in K8688 BIONICLE Mistika Collection.
