Kohrak
Ice-wielding Bohrok from the 2002 original wave, the foundational design for all subsequent Bohrok variants.

Unlike later advanced BohrokBohrokHive-minded mechanical creatures designed to reshape worlds, the Bohrok represent a threat the Toa Mata never expected.-Kal variants, standard Kohrak are the baseline model: simpler, more numerous, easier to overwhelm if you can bypass their swarm tactics. Their strength lies in numbers and organization, not individual prowess. They tunnel through ice and snow, launch coordinated attacks, and retreat in formation when outmatched.

Krana and Control#
What's genuinely interesting about Kohrak is their complete dependence on krana. Remove the krana, and the BohrokBohrokHive-minded mechanical creatures designed to reshape worlds, the Bohrok represent a threat the Toa Mata never expected. becomes an empty suit. This mechanism shows up across all BohrokBohrokHive-minded mechanical creatures designed to reshape worlds, the Bohrok represent a threat the Toa Mata never expected., but it matters here because it defines their entire existence. They're drones, full stop. No personality, no choice, no hierarchy beyond what the krana impose.
