Epena

Epena was a Po-Matoran

Metru Nui
Nothing is known of Epena's life in Metru Nui. All that is known is that he was saved by the Toa Metru during the Great Cataclysm, after being stuffed in a Matoran Pod. He was awakened on Mata Nui and gradually lost his memory of the past and became weaker.

Mata Nui
Epena was a Quarry Master on Mata Nui, helping Hafu with his sculptures. During the Bohrok's attack Epena was one of the Po-Matoran forced to move in Ga-Koro for a short while. There he witnessed how the Pahrak collapsed.

After the Bohrok-Kal strike, Epena was built into a stronger form by the Turaga. He later moved back to Metru Nui with the other Matoran.

Return to Metru Nui
He had returned to Metru Nui and had helped with rebuilding it, until the Staff of Artahka 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.
