Bohrok Kal Lehvak-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.
Lehvak-Kal is the fastest and most unpredictable Bohrok-Kal. Its vacuum shield gives it two powerful modes of defense, and there is no way for a Toa Nuva to know which it will choose. Lehvak-Kal makes full use of the terrain, and can disappear into the jungle in an instant. Lehvak-Kal’s vacuum shield can suck all the air out of a given area, causing a destructive implosion. It can then release the evacuated air in a single blast that has the power to smash through solid rock.
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.
