"Each Bohrok carries within it a Krana, their greatest strength. Also their greatest weakness."

The Krana are small organic creatures that link Bohrok or other beings to the Bohrok swarms.
The original Krana were created by the Great Beings by exposing to Energized Protodermis the remains of the process that created the first Matoran. This procedure resulted not only in Krana, but also Zyglak.
The Bahrag were later taught how to create Krana on their own and were given Energized Protodermis to do so. A carving depicting the process the Bahrag used was inscribed on a tunnel above Metru Nui.
When the Bohrok first attacked Mata Nui, the Turaga of the island instructed the Toa Mata to collect a specimen of each of the eight Krana varieties from each of the six Bohrok types. The Toa placed the forty-eight Krana into niches on the floor of a Bohrok Nest, thus opening up pathways to six Exo-Toa.
After the Bahrag were defeated and imprisoned in a Toa Seal, the Matoran dumped many Krana into deep pits that they sealed and marked with warning signs. However, many Krana still remained in stasis in their nests.
Abilities and Traits
The Krana receive commands from the Bahrag and can assimilate biomechanical beings to the Bohrok swarms by latching onto their faces and controlling their minds. Krana cannot control organic beings, such as those native to Spherus Magna, as they do so by overriding their host's programming. Krana can also slow down their life processes. Like the Matoran and Toa, Krana are a form of artificial intelligence.
All Rahi fear and avoid Krana as they sense something about them is amiss.
There are forty-eight varieties of Krana: for each of the six breeds of Bohrok, there are eight types that each bestow a different power. Bohrok cannot serve the Bohrok swarms without a Krana, and if a Krana is ever lost it is the task of the Bohrok Va to replace it.
The eight types of Krana are listed below.
|Krana Xa||Swarm Commanders
Allows its Bohrok to form complex strategic plans.
Allows its Bohrok to fly short distances.
Allows its Bohrok to tunnel through almost any substance on Mata Nui.
Gives its Bohrok enhanced strength.
|Krana Za||Squad Leaders
Allows its Bohrok to communicate telepathically with others within the swarm. It also gives its Bohrok the ability to read the minds of other beings.
|Krana Ca||Clearance Workers
Allows its Bohrok to shield itself and others from attack.
Allows its Bohrok to detect distant obstacles.
Allows its Bohrok to see in the dark.
Krana have both active and dormant states. Krana are active if they are inside an operating Bohrok or if they are attached to a being's face. When not commanding a host they go dormant, conserving energy and turning a different color. Bohrok Va do not need Krana to operate, so the Krana they bear are always in the dormant state.
Krana were first released in early 2002 in the Bohrok and Bohrok Va sets as rubbery plastic accessories, with one random Krana appearing in each set in the color used by that particular Bohrok or Bohrok Va. Bohrok sets would fling their Krana as a defense mechanism when their eyes were pressed, while Bohrok Va would fling their Krana when their right arm was moved.
Krana were also available in the "Krana" set (set #8569), a small boxed set that included three random Krana and two random Golden Kanohi or silver Kanohi worn by the Toa Mata. While the back of the box showcased only active-colored Krana, the box also could contain dormant-colored Krana. During the latter half of 2002 the "Kanohi Nuva and Krana" set (set #8598) became available, containing three random Krana in the same colors as before as well as two random Kanohi Nuva in any of the primary colors of the six Toa Nuva.
Krana produced in the latter half of 2002 each bear three Matoran letters on their reverse sides.
"These Krana are not objects of power, like our Kanohi - they are alive!"
— Kopaka, To Trap a Tahnok
"I am a Bohrok Za, a squad leader. My telepathic powers are meant to communicate with my swarm. But your thoughts are so slow and transparent that I can read them with no effort at all."
— Krana-controlled Lewa to Onua, Beware the Bohrok
"I know the Krana controls your body, Lewa, but not your will. If it is so strong that it can make you harm a friend... Then go ahead -- I will not defend myself. But I know you, Lewa. I have fought beside you... and I know you are stronger than this parasite."
— Onua to Lewa, Into the Nest
- Matoran would classify Krana as Rahi, even though they are not.
