Not much is known about Okoth's life before the Great Cataclysm except that she was placed into a Matoran Pod and was taken to Mata Nui.
Okoth was the trader of Ga-Koro, but after trading from village to village, her sales became low. She also ran a shop in Ga-Koro. She was also rebuilt at the Kini Nui into a stronger form. She also aided in the construction of boats for the return-trip to Metru Nui.
Return to Metru Nui
Okoth returned to Metru Nui with the other Matoran and Turaga, and helped to rebuild it until the Staff of Artakha repaired the rest of the city. She was also present during the ceremony for Matoro.
Sometime later she evacuated the Matoran Universe onto Spherus Magna with the other Ga-Matoran and established a village with the Water Tribe in the Great Sea.
