The Bahrag, Cahdok and Gahdok, are the queens of the Bohrok swarms.

The Bahrag were created by the Great Beings with the sole purpose of leading the Bohrok in cleansing the island of Mata Nui and crafting krana for them. They were not given the knowledge of anything beyond the relevance of their task, and have no knowledge of any other beings, such as Makuta Teridax or the Toa Mata. An early record of the Bahrag is on a carving in the tunnels below the island of Mata Nui. This carving depicts the Bahrag dipping a mysterious object into Energized Protodermis, and emerging with a krana, a practice the Bahrag have been known to do.

Shortly after their creation, the Bahrag mutated six Bohrok into the Bohrok-Kal, as a precaution in case they should be incapable of contacting the Bohrok swarms. They also made the krana-kal, which were capable of functioning independently, without needing the Bahrag to direct them.

The Bahrag were awoken via a sonic signal sent by Makuta Teridax. Due to the lack of instructions on how to deal with being woken up prematurely, they assumed it was time to cleanse the island, and sent the Bohrok to do their job. Though they encountered several unpredicted obstacles, the Bahrag managed to overcome each one by their preferred method of assimilating the foe into the swarm. They remained in their nest for several days, directing the Bohrok as per their task.

The Bahrag were soon confronted by the six Toa Mata, who had successfully acquired eight breeds of krana and unlocked the Exo-Toa armor. The Bahrag recognized the Toa Mata as fellow servants of Mata Nui, and referred to them as such. However, they were attacked, and retaliated against the Toa. Three of the Toa clashed with Gahdok, while the other three fought against Cahdok. The Toa Mata slowly gained the upper hand, due to the extra power afforded to them by the Exo-Toa. However, as the Bahrag were slowly cornered in the same chamber, their own power of symbiosis increased their powers immensely, to the point where even a blast from the Exo-Toa dissolved several feet from them. Having battled to a stalemate, the Toa willingly shed their suits, regaining their hampered Elemental Powers. Realizing that they could not defeat the Bahrag, the Toa Mata combined their elemental powers in a last ditch effort, forming a Toa Seal, and trapped the Bahrag inside. This caused their fall into tubes of Energized Protodermis, transforming them into the Toa Nuva.

The defeat of the Bahrag activated the release of the Bohrok-Kal. Though the Bohrok-Kal managed to defeat most of the obstacles and locate the Bahrag, they were overpowered by energy fed to them by the Nuva Symbols, and stopped short of freeing their masters. The Bahrag remained trapped in a Protodermis cage, waiting to be released so that they could continue to do their job.

Months later, the Bahrag were approached by the Toa Nuva, who had realized that the cleansing of Mata Nui was vital to the survival of the universe. Using their elemental powers, they broke the seal containing the queens. After a brief conversation, the Bahrag sent a signal to the Bohrok, awakening the swarms once more. From there, they continued their appointed task, clearing the island of Mata Nui. Though they encountered unexpected resistance from Kardas, the Bohrok swarms eventually overcame all obstacles and completed their job.

After the Matoran Universe was damaged beyond repair, the Bahrag left their nest and immigrated to Spherus Magna.[4][5]

Abilities and Traits

Cahdok and Gahdok channeling their Stone powers

The Bahrag possess a wider range of the six Bohrok's abilities: Fire, Ice, Earth, Acid, Stone, and Water. The Bahrag also possess the power to create powerful illusions, which they use to protect their nest from intruders. They can also communicate telepathically to the krana.[1]

The Bahrag are symbiotic, drawing power from each other. The closer they get to each other, the more concentrated their powers become.[6] When they stand next to each other, their defensive capabilities were so great that a powerful barrier formed around them.[7]

The two Bahrag could be distinguished by their antennae (Cahdok's are long and thin while Gahdok's are short and clubbed) or their color (Cahdok is blue while Gahdok is red).[2][3]

Set Information

The Bahrag in set form

8558 Cahdok & Gahdok was released as a single boxed set in the summer of 2002, containing 630 pieces. Their tails acted as handles so one could more easily pull the trigger in their torsos, which made them thrust their necks forward while biting with their mouths. When one bit and removed the other's chest, the other would be incapacitated as if in injury. In this way the Bahrag's biting function was advertised as a means for the two to battle each other or another set. Instructions were also included with the set to build a non-canon alternate model.


"All the powers of the Bohrok belong to us! If fire will not defeat you, then taste the power of stone!"
— Gahdok, The End of the Toa?

"You dared challenge the Bohrok swarms? You have no hope! -- The mission will proceed!"
— Gahdok, The End of the Toa?

"Fools! You think you have won -- but you cannot imagine what you have unleashed!"
— Gahdok, Beware the Bohrok


  • The Bahrag called the Toa the "brothers" of the Bohrok, referring to the fact that they serve the same greater power: that of the will of the Great Spirit Mata Nui.
  • The Bahrag are not Rahi,[8][9] even though Matoran would classify them as such.[10][11]
  • During their travels through the Place of Shadow, Gali, Tahu, and Kopaka come to the conclusion that some or all of the illusions encountered in the Bohrok nest were Makuta's doing.[12][13] However, they were mistaken,[14] and the BIONICLE: Encyclopedia Updated maintains that the Bahrag have illusion powers of their own.[1]
