Krana-Kal

Krana-Kal are specialized Krana, mutated by the Bahrag's energy and Energized Protodermis. Like regular Krana are literally the brains of the Bohrok, the Krana-Kal are the driving force of the Bohrok-Kal. The Krana-Kal are unlike the other Krana in the way that they can act independently, without depending on the Bahrag, and they are able to communicate with other beings by way of telepathy. Krana-Kal also contain a unique property which allows them to turn a silver color and generate an impenetrable shield around their hosts when at the final stages of their mission.
