Lego Bionicle: The Legend of Mata Nui is a canceled action-adventure video game developed by Saffire. Based on the Lego Group's Bionicle line of constructible action figures, the game was intended to release on Microsoft Windows computers in late 2001 and the GameCube in early 2002. The game was designed as a direct sequel to Saffire's Game Boy Advance game Lego Bionicle: Quest for the Toa, which was released in October 2001. The story of The Legend of Mata Nui was meant to serve as a conclusion to the 2001 Bionicle story arc, focusing on the Toa, heroic elemental warriors destined to defeat the evil Makuta, who is attacking the island of Mata Nui with corrupted Rahi animals.
