List of Bionicle Characters - Bohrok

Bohrok

The Bohrok are mechanical, Insect-like creatures, they are the remains of destined Av-Matoran. The Bohrok are a race of drones driven by little, mask-like organisms called Krana. Existing only for a singular purpose, they will do anything and everything to fulfill the mission of cleaning the island of Mata Nui. Unfortunately, Makuta Teridax woke them early and they began this "cleaning" job while Matoran were still living there. The Toa Mata stopped this rampage, but then had to face six elite Bohrok-Kal that tried to release the swarms again after stealing the Toa's elemental powers.

Now that the island is uninhabited, the Bohrok cleansed it completely, then returned to their slumber should they ever be needed again.

• The six main breeds of Bohrok and their respective elements are:
• Tahnok, Bohrok of Fire, the most aggressive and destructive of all the Bohrok types. They use their mastery of fire to burn whatever is in their way. Even with their Krana removed, Tahnok are hard to tame.
• Gahlok, Bohrok of Water, the trickiest Bohrok opponents - they never attack the same way twice. Able to control water, the Gahlok use tidal waves to flood Mata Nui. Remove their Krana, and they can be tamed.
• Lehvak, Bohrok of Acid, the only kind of Bohrok designed for combat. Using their crushing shields and dissolving spray, they exist to destroy anything that lives on Mata Nui. Clever and unpredictable, stopping the Lehvak may be the Toa Mata's greatest challenge. With their Krana removed, they are still highly difficult to tame.
• Pahrak, Bohrok of Stone, the most unrelenting of Bohrok, never giving up until their destructive work is done. Their shields have the power to set off earthquakes, and they can move massive boulders with their bare hands. No matter what obstacle, Pahrak can reduce it to rubble. But if you remove their Krana, the Pahrak can be tamed.
• Nuhvok, Bohrok of Earth, the tunnelers of the Bohrok, using the power of their shields to blow up rock and blast through passages through the earth. They even have the power to bring down a mountain. Although their reactions are slow, they are dangerously fierce when cornered. When their Krana is removed, they can be put to work rebuilding what they have destroyed.
• Kohrak, Bohrok of Ice, the most cold-blooded of the Bohrok. They want to bring a new Ice Age to Mata Nui - and they have the power to do it. Their shields are capable of freezing anything and can even fire blasts of ice. Get in their way and you will wind up in a block of ice.

They also appear in Mask of Light frozen in Ko-Koro, even scaring Jaller and Takua.
