Kantai

Kantai was a Ko-Matoran.

Metru Nui
Barely anything is known of Kantai's life in Metru Nui. All that is known is that he was put into a Matoran sphere along with all the other Metru Nui Matoran and later rescued by the Toa Metru during the Great Cataclysm.

Mata Nui
Kantai lived near the ice flows in a small cave in Mata Nui. He knew the Principle of Willpower and taught it to any that would ask.

Return to Metru Nui
Kantai returned to Metru Nui and helped to rebuild it until the Staff of Artakha was used to repair the rest of the city.
