Kivi

Kivi was a Po-Matoran.

Metru Nui
On Metru Nui, Kivi was a Chute Manager. It was Kivi who alerted Ahkmou to the fact that Nidhiki and Krekka were looking for him, which encouraged him to join Onewa and the Toa Metru on their quest for the Great Disks.

Mata Nui
On Mata Nui, Kivi was a stone hewer and worked hard in Po-Koro to ensure that all stones were ready for carving.

Return to Metru Nui
When the Matoran returned to Metru Nui, Kivi helped in the construction of the Boats needed to make the trip across the Silver Sea. He now resides in Metru Nui once again. He then began working on the statues of Teridax that "Turaga" Ahkmou ordered the Po-Matoran to carve of him.

Spherus Magna
Sometime later he evacuated the Matoran Universe and is currently living on Spherus Magna.
