Onua Nuva Reviews
Brickipedia
“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... More 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.”

“Onua Nuva is a great figure. Sure, he's not the coolest set from the Toa Nuva sub-line, but he really has an unique aspect when compared to most of the other Toa Nuva. My main complaint at the time was he lacked the awesome claws he sported in his previous incarnation, but... More the new weapons are up for some pretty nice uses, too.”

“The Onua Nuva set was released in summer 2002 as one of the six Toa Nuva sets. The set consists of forty-one pieces. By combining pieces from Onua Nuva with 8568 Pohatu Nuva and 8572 Tahu Nuva, one can build Akamai Nuva.”
