Bohrok Kal Gahlok-Kal
When the Toa battled and then trapped the Bahrag twins, their captivity awoke the Bohrok-Kal. The Kal are six Bohrok controlled by advanced krana. They have only one mission in life: find the Bahrag, free the Bahrag and unleash the swarms once more. They are driven neither by good or evil, but by duty.
Like water itself, Gahlok-Kal is hard to catch. Its surface is designed to make it difficult to grasp, and it can “flow” around obstacles when need be. Gahlok-Kal is stealthy as well, able to sneak in and out of a Matoran village without ever being seen or heard. Gahlok-Kal’s tool is a magnetic shield. This collects, controls and directs the power of magnetism from the earth – which can be employed as a defensive force field against attack, or be used as a formidable defensive weapon.
The Bohrok-Kal were destroyed when the Toa Nuva channeled all their Elemental Energies into the symbols on the protodermis cage holding the Bahrag, which they were touching with their krana. The Bohrok-Kal were consumed by their own power.
