Large flying robots made of LEGO pieces that serve the evil perfectionist businessman Lord Business. Their goal is to suppress chaos and get everything in order so that Lord Business can glue the entire LEGO world together with his secret weapon, the Kragle. Despite being large blocky black robots with mechanical extendable claws and rockets, they themselves actually have high-pitched voices although they don't speak much and they can still get confused by the Master Builders' LEGO creations.
