Bionicle: Challenge of the Rahi

In 2001, The Lego Group launched Bionicle: Challenge of the Rahi, a single-issue comic that expanded the early lore of the Bionicle universe. The story pits the heroic Toa against the Rahi, the wild and dangerous creatures of the island of Mata Nui, in a standalone adventure. While brief, this issue is notable for its role in fleshing out the world's ecosystem and threats during the franchise's formative first year.
