Piatra was a Po-Matoran.
Little is known of Piatra's life in Metru Nui. It is known is that he lived and worked in Po-Metru and was rescued by the Toa Metru during the Great Cataclysm, after being placed in a Matoran Pod by the Vahki.
He was brought to Mata Nui by the Toa Metru and lived in Po-Koro. Piatra was a guard of Po-Koro with Ally. He was also rebuilt at the Kini Nui into a stronger form. He also helped construct boats for the return trip to Metru Nui.
Return to Metru Nui
After Piatra's return to Metru Nui he helped the other Matoran rebuild the city until the Staff of Artakha was used to repair the rest of the city. He then began working on the statues of Teridax that "Turaga" Ahkmou ordered the Po-Matoran to carve of him.
Sometime later he evacuated the Matoran Universe onto Spherus Magna.
- Piatra means "stone " in italian.
