Ko-Koro

Ko-Koro's location was chosen by Toa Nuju after the events of the Great Cataclysm. When the Ko-Matoran were awakened by the Turaga, and following the first anniversary of their settlement, the village began suffering from Infected Rahi attacks. Teridax's harassment would continue for centuries until the coming of Toa Kopaka.

Ko-Koro would also be damaged during the first strike of the Bohrok swarms of Tahnok, and later partially destroyed by the Rahkshi. When Metru Nui was discovered the Ko-Matoran departed. It was eventually destroyed by the Bohrok once the Toa Nuva freed the Bahrag.
