Onua Nuva
The Toa Nuva were created after the Toa of Mata Nui battled and imprisoned the Bahrag, and fell into Energized protodermis.
Onua's powerful, tunneling hands have been enhanced to become an astonishing set of chainsaws that chew their way through rocks and earth, allowing Onua Nuva, the Spirit of Earth, to tunnel underground. If trouble is near, the saws become rollerblades to move him along at faster speeds over rough terrain, despite the weight of his amazing new armor.
The Toa Nuva have since been on adventures to the island of Artakha. They are now in Karda Nui attempting to save the life of the Great Spirit Mata Nui.
