Rahi are non-intelligent creatures in BIONICLE that live in the wild. Most Rahi vehicles and characters were created by the Brotherhood of Makuta whose original job was to create and alter creatures as needed. Even though most Rahi are little more than generic creatures a few have appeared in prominent roles in the BIONICLE storyline.
