"It is said that the Bohrok sleep an eternal sleep, waiting to hatch. Once awakened, the swarms are unstoppable... a force so powerful, they can reduce mountains to rubble and turn life-giving rivers dry as the desert sands!"
— Turaga Vakama, The Bohrok Awake
|Headquarters||Bohrok Nests above and below Metru Nui|
|Goals||Level the island of Mata Nui|
|Allies||Bohrok Va, Bahrag, Toa Nuva|
|Enemies||Toa Mata, Kardas Dragon (both formerly)|
Initially awakened early by Makuta Teridax, the Bohrok swarms were defeated by the Toa Mata when the Toa trapped the Bohrok's twin Bahrag queens in a cage of solid Protodermis. The swarms were reawakened by the Toa Nuva to resume their quest of destruction, and have since gone back to sleep after their mission was completed.
The Great Beings designed the Bohrok to clear away Mata Nui's camouflage once he was ready to depart a world. They based the Bohrok's design on their previous creations, the Baterra. The Great Beings destined a percentage of Av-Matoran to transform into Bohrok at a certain point of their lives. Once the transformation was complete, they were then teleported to the Bohrok Nests to be fitted with Krana.[BL10]
The Brotherhood of Makuta knew about Bohrok very well, and placed six sets of Exo-Toa armor as a failsafe against a possible Bohrok rampage.[BEU, p. 31] They also ordered the Nynrah Ghosts to construct replicas of Bohrok to aid them in their conquest of the universe.
The first recorded encounter between Bohrok and Matoran occurred in Metru Nui, when a group of Lightstone Miners broke into a Bohrok Nest in Onu-Metru by accident. Inside they discovered the word "Bohrok" carved into the wall. Several were immediately shipped to the Archives, where Archivists quickly discovered that the Bohrok were inorganic and that the dormant Krana inside each Bohrok were organic and alive. The Bohrok showed no evidence of having ever been built. An Archivist named Mavrah hypothesized that the Bohrok were once biomechanical beings that had somehow evolved to become unthinking machines driven by organic brains.[BA5] However, this theory was lost over time.[BE]
During the return trip from Mata Nui to Metru Nui, the Toa Metru encountered some Bohrok.[MoS] These Bohrok were controlled not by Krana, but by worms that had been captured by Teridax, and subsequently escaped their confinement.[P]
1,000 years later, after his initial defeat by the Toa Mata, Teridax sent a beacon to wake the primary Bohrok swarms. As planned, the Bohrok immediately made for the surface of the island of Mata Nui, and began the Bohrok Invasion. The Toa Mata battled the swarms, collecting each breed of Krana and tracking their menace to the underground lair of the Bahrag, twin queens of the Bohrok.[BC2]
After the defeat and imprisonment of the Bahrag, the Matoran reprogrammed the Krana-less Bohrok to aid in rebuilding the villages they had destroyed. However, all the Bohrok and their smaller helpers, the Bohrok Va, returned to the nests when the Bahrag were on the verge of being freed by the Bohrok-Kal.[BC3]
About a month or two later, following directives listed on a scroll in the Great Temple, the Toa Nuva returned to the Bahrag's lair and freed the queens, who proceeded to re-awaken the swarms to resume their mission of devastation.[BL7]
This time, the Bohrok proceeded without interference, except for a new arrival, the Kardas Dragon, which destroyed several Bohrok before being badly injured by the swarms.[TNB, Ch. 8] With no further hindrance, the Bohrok quickly finished their task and promptly returned to their nests to go back to sleep.
During the Siege of Metru Nui led by the Brotherhood of Makuta, the small group of Bohrok in the Archives were awakened by Toa Krakua, using his Sonics powers. The group then emerged onto the surface of Ta-Metru, where they began fighting the Rahkshi, who were unwittingly blocking the way to Mata Nui. The Bohrok eventually won the battle and promptly left in order to fulfill their programming.[DW, Ch. 9]
In an alternate universe, the Bohrok were re-awoken on the island of Mata Nui after the Great Spirit died. As they no longer had a reason to perform their island-cleaning task, they instead worked side by side with Matoran.[TK]
Abilities and Traits
Bohrok are insectoid, non-living, robotic entities which normally function under the control of a Krana, which follow telepathic commands by the Bahrag queens. Krana are regarded as the Bohrok's greatest strength, as it allows them to assimilate others into the swarm, but also their greatest weakness, since removing the Krana renders the Bohrok dysfunctional and thus helpless. The Matoran of Mata Nui were able to modify the Bohrok when their Krana were removed to obey simple commands.
Bohrok possess extendable necks that allow them to thrust their heads forward over a great range in a short time. They use this ability to chip away at obstacles in a jackhammer-like fashion, or as a last resort, to fling their Krana onto the faces of attackers.
For travel, the Bohrok can compress their bodies into a spherical form, a form they also take while lying dormant inside the Bohrok nest. In this form they can roll across the ground at high velocity and, when fitted with Krana Vu, fly short distances.
If faced with an obstacle too great for individual members to overcome, Bohrok have the ability to form Bohrok Kaita, which pools the attributes of the three individual Bohrok into one more powerful being.
There are six types of Bohrok:
- Tahnok, Bohrok of Fire
- Gahlok, Bohrok of Water
- Lehvak, Bohrok of Acid
- Pahrak, Bohrok of Stone
- Kohrak, Bohrok of Ice
- Nuhvok, Bohrok of Earth
Each breed can channel their specific element or power through a pair of shields which every Bohrok carries. The six breeds approach their mission in different ways and are aided by corresponding Bohrok Va.
All six Bohrok breeds were released in 2002 as canister sets. When a lever is pressed on the Bohrok's back, its head snaps forward, and snaps back when the lever is released. Each Bohrok also has a head plate of their respective element color, mixed with transparent plastic to see the Krana inside. Pressing down on the eyes of the Bohrok can force open the head plate and launch the Krana out.
"It is said the Bohrok sleep an eternal sleep, waiting to hatch. Once awakened, the swarms are unstoppable. They are a force so powerful, they can reduce mountains to rubble and turn life-giving rivers dry as the desert sands. The Bohrok swarm won't stop - not until all that is known of Mata Nui is gone.
Their strength goes beyond their powerful exterior; it is hard to see and well protected. It is the Krana, the creature within. But Krana are also their greatest weakness for even the mightiest Bohrok can be humbled, if parted from their Krana."
"It must be cleaned. It is time. Clean it all. It is time. All obstacles will be removed. Clean it all. It must be cleaned. It is time."
