From the depths of Mata Nui, they came... six elite Bohrok, the Bohrok-Kal, with one mission: to free the Bohrok queens and unleash the swarms again! Only the Toa Nuva stand in their way... but the Bohrok-Kal have stolen the elemental powers of the heroes, leaving them helpless. Will the Toa Nuva's first adventure be their last?
One of the most dangerous of the Bohrok-Kal, Nuhvok-Kal has single-handedly defeated both Tahu Nuva and an entire Bohrok swarm. With its gravity shield, Nuhvok-Kal can increase gravity (making an opponent too heavy to stand), or eliminate it (causing a foe to float into the air)! Look for 72 Limited Edition genuine Sterling Silver Krana-Kal and 5,000 Limited Edition silver-colored metal versions in Bohrok-Kal packages. They're randomly packed so you never know where the power of Silver might be found (not available in Europe)!

The Nuhvok-Kal sacrifices speed for sheer power. Its gravity shield makes it one of the most dangerous Bohrok-Kal, but it seems to be in no hurry to fight. Perhaps the reason is that as soon as it brings its gravity shield into play, the struggle is over in seconds...
The Nuhvok-Kal’s gravity shield has the dual ability to negate gravity (so that its target becomes lighter than air and starts to float away), or intensify gravity (so that its target becomes much more dense, and sinks into the ground). To be sure of defeating Nuhvok-Kal, the Toa Nuva should face him only above ground.
Pushing the lever on its back will cause its head to spring forward.
