Patrol the ruins of the ancient arena with the menacing Skull Slicer! This ancient champion has been animated by the dark magic of the Skull Spider Mask, fusing him with his razor-sharp hook blades. Create fearsome combat poses and turn the wheel on Skull Slicer's back to activate the 4 battle arms all at once. Use the hook blades to rip off masks and pick them up with the mask grabber. Any LEGO® BIONICLE® hero wanting to pass through the arena will have to get past this wicked warrior first!
