Bahrag

The Bahrag were the twin Bohrok Queens, Cahdok and Gahdok.

They each had all the powers of the main six Bohrok breeds, plus the ability to cast illusions that seemed real and solid until one stopped believing them. The Bahrag's powers grew stronger the closer they physically were to each other. They could also create Krana by dipping an unknown object into a pool with an unknown substance.

History
The Bahrag were driven by a single goal: to "clean it all". They cared little for anything else, unless it got in the way of their mission. When Teridax woke them, they assumed it was time for "cleaning" and immediately sent out the swarms, regardless of the fact that there were still inhabitants living on the island. The Toa Mata tried to fight the Bahrag with their new Exo-Toa armor, but the armor proved little help as it blocked the the use of their Elemental powers. The Toa instead removed the armor and combined their Elemental powers, encasing the Bahrag in a Protodermis cage and ending their control over the swarms.

Bohrok-Kal
If the Bahrag were defeated, the Bohrok-Kal would be awakened. The Kal stole the Toa Nuva's Nuva Symbols and intended to free the Bahrag by inserting them on the Nuva Cube. The Bohrok-Kal were defeated by too much power being given to them, and the Bahrag remained in their cage.

Freedom
Axonn gave the Toa Nuva a mission to free the Bahrag. The Toa traveled back to the nest and combined their powers. Thus, the Bahrag commanded the Bohrok to "clean up" Mata Nui. The Bahrag ran into no trouble this time and did their mission without further complications. After this, they presumably retired back to sleep, waiting for the day the Bohrok would need to be unleashed again.

After Teridax's death they retreated to Spherus Magna without the swarms.

Set Information

 * Both Bahrag were released together in one set as a 2002 titan set. They were set number 8558.
 * Both Bahrag together had a total of 630 parts.
 * While the Bahrag were meant to work together in the story, the sets were obviously meant for fighting, as the Bahrag's function allowed them to lunge forward and bite, which if done correctly could pull a pin out of the other Bahrag's chest, causing their biting function to stop working until the pin was reinserted.
 * The Bahrag could be combined to create a "Bahrag Spider." This was not included in the storyline.
 * The Bahrag were the first female box set to be released.
