70789-1 Bionicle 2015 108 parts 19.1% repair risk Easy

Onua, Master of Earth, delves into the underground world in the LEGO Bionicle 70789-1 set, seeking the mystical Golden Mask of Earth. He wields a versatile earthquake hammer, which converts into turbo shovelers, designed for powerful excavation and direct combat against subterranean threats. His journey is complicated by the included pale green Skull Spider, aiming to activate Onua’s mask pop-off trigger in battle. A specialized wheel-operated bashing battle arm provides dynamic action, enhanced by the figure's fully posable ball joints for varied display and play scenarios. Onua features striking armor, including four golden BIONICLE shells and a detailed tribal chest decoration, equipping him for his mission.
