Rahi were the animals in the Matoran Universe. The word Rahi meant "beast" in an ancient Matoran dialect. Rahi lived anywhere in the Matoran Universe, from scorching heat, to freezing cold, to the deepest depths of the earth. All the factions in the Bionicle world had made use of Rahi, whether for transportation, corruption, or a supplement to their armies. The Rahi were originally made by the Brotherhood of Makuta to assist the Matoran in their work before the Brotherhood became corrupt.
