The Bahrag twins, Cahdok and Gahdok, lurked beneath the surface of Mata Nui, protecting the secrets of the Bohrok swarms. If their snapping jaws were not enough to stop a foe, they also possessed great mental abilities and the elemental powers of all of the Bohrok.
Cahdok had the power to create illusions that could trick an opponent into fighting nothing but empty air. The Bahrag possessed all the powers of the Bohrok. Both Bahrag were able to create illusions.
Cahdok and Gahdok were the queens of the Bohrok swarms. They possessed all the powers of the six Bohrok species, and they telepathically controlled all the krana. They were also symbiotic, meaning they drew strength from each other; the closer they were to each other, the more powerful they both became.
Gahdok (red) and Cahdok (blue) were the sister queens of the Bohrok swarms. They spoke telepathically. When the two of them were brought together, their power was increased; rocket blasts from the Exo-Toa exploded just short of them, as if they were protected by a force field. They could also create illusions, tricking Toa into fighting nothing but empty air. The force field was an enormous drain on the Bahrag, however.
The Bahrag created the Krana and through them directed the actions of the Bohrok swarms. They were unaware that Matoran were living on the surface during the Bohrok invasion of the island of Mata Nui. The Toa Nuva defeated and trapped the Bahrag in a cage of solid protodermis. The Bohrok-Kal later attempted and failed to release them. Eventually the Toa Nuva released the Bahrag as part of their preprations for awakening Mata Nui.
The Bahrag possessed the elemental powers of the six Bohrok breeds and the ability to create lifelike illusions.
The Bahrag were the twin queens of the Bohrok swarms. Created by the Great Beings, their job was to manufacture the krana needed to control the Bohrok. The two Bahrag, Cahdok and Gahdok, had a mental link to the krana, which enabled them to make sure the Bohrok carried out their mission and could respond to any threat. The Bahrag were also served by robotic creations called the Bohrok Va. The Bahrag were not evil creatures. Their mission, to cleanse the island of Mata Nui, was the will of the Great Spirit. However, the Bohrok were never meant to be unleashed when anyone was living on the island. The Bahrag possessed all of the powers of the Bohrok as well as the power to create illusions. They gained strength from being close to each other, but weakened if they were too far apart. When Cahdok and Gahdok were right next to each other, an invisible barrier formed around them that could stop even a blast from Exo-Toa armor. The Bahrag lived in an underground cavern beneath Mata Nui.
The Bahrag were uninterested in political alliances and had no knowledge of the Brotherhood of Makuta.
The Bahrag were not aware of the energized protodermis tubes beneath their chamber.
The Bahrag did not sleep when the swarms were asleep.
There was only one pair of Bahrag.
