Kuma-Nui

Kuma-Nui were giant rat-like Rahi that lived in the maintenance tunnels of the Archives, particularly in the Ta-Metru or Ko-Metru areas of Metru Nui (they later migrated to Ta-Wahi and Onu-Wahi). A majority of these Rahi later migrated to the island of Mata Nui after the Great Cataclysm, but returned after the Bohrok cleansed the island.

Set information

 * The Kuma-Nui could be made by combining the Muaka and Kane-Ra set.

Trivia

 * Despite being (seemingly) rat-based, the Kuma-Nui got their name from "Kuma (くま)", the japanese word for "bear."
