Bionicle #20

Hunted as imposters and suspected in Toa Lhikan's disappearance, the Toa Metru are forced to flee for their lives. Stowing away aboard a Le-Metru airship, they mistakenly believe themselves to be beyond the reach of the Vahki order enforcement squads.  Meanwhile, a far more dangerous threat is looming in the shape of Nidhiki and Krekka, the Dark Hunters. Dispatched by Turaga Dume to capture the outlaws, they are determined to bring the Toa in alive - if not necessarily undamaged. For the Toa, capture would mean both Lhikan and the city itself would be lost forever. But can they hope to survive against beings who live to hunt Toa?
