Rahkshi Rahkshi are suits of armour controlled by slug - like creatures called Kraata in the BIONICLE storyline . Rahkshi are often called the " sons of Makuta " . Set Release History . Six Rahkshi sets were released in 2003 . They were : A smaller yellow Rahkshi was released in 2010 as part of the BIONICLE Stars sub - theme . It is a scaled - down version of a Rahkshi of Heat Vision . It was also one of the last BIONICLE sets released . Biology . When a Kraata , a slug - like creature made from a Makuta ' s evil essence , is exposed to a substance called energized protodermis , it dies and mutates into inanimate Rahkshi armour . A second Kraata of the same type can then enter the armour through a hatch in its head and control it . A Rahkshi ' s power is at least equal to a stage - 6 Kraata ' s and likely even greater , though it is severely weakened when separated from the staff that it wields . Rahkshi can also shift into a flight mode , but this ability is used for transport as opposed to combat . Rahkshi stand about 8 feet tall and are semi - humanoid in appearance . While all media for BIONICLE shows the Rahkshi ' s heads splitting open to show the Kraata inside , the toys do not have this feature . Instead , the toy Kraata are enclosed in compartments on the Rahkshi ' s backs . Personality . When Rahkshi have no mission from a Makuta to fulfill , they act as especially violent and dangerous beasts . But with direction and guidance from Makuta , they have power enough to overtake even the powerful Toa Nuva . Their violent nature makes even the Makuta reluctant to send them out , as they know they will destroy anything in their path . History . The best known of the Rahkshi ( and the only ones named ) are the six who Makuta sent to find and retrieve the Mask of Light : Turahk , Guurahk , Lerahk , Panrahk , Vorahk , and Kurahk . Together , these six were responsible for heavily damaging the villages of Onu - Koro and Ko - Koro and completely destroying Ta - Koro ; Lerahk also poisoned Toa Tahu and Turahk killed Jaller before the Rahkshi were destroyed by Toa Takanuva . Makuta probably selected these six as a symbolic attack on the Principles of the Matoran race ; for instance , Ta - Matoran follow the Principle of Courage , which is countered by Turahk ' s Fear . Later , the Toa Inika , which included the resurrected Jaller , sought to claim the Mask of Life . As one of their tests , the mask brought memories of old enemies to life , including Turahk . While Jaller struggled with the unpleasant memory of his death , he succeeded in defeating the Rahkshi . The memory of death affected Jaller in a later test as well ; when a sacrifice was demanded of the Toa , remembering Turahk ' s attack caused Jaller to hesitate long enough for his teammate Matoro to volunteer . A thousand years prior , there were a number of Rahkshi in the city of Metru Nui . While searching for the Vahi Mask of Time , Makuta summoned every Rahkshi in the city to attack the time - controlling mutant Voporak . While the entire army of Rahkshi was aged to death by Voporak ' s defensive field , they caused the distraction needed for Makuta and Toa Vakama to slip away unnoticed . It was here that Vakama learned of the Rahkshi ' s connection to Makuta . When the Toa Hagah were mutated by Roodaka , she gave them Rahkshi - like heads and staffs as a kind of sick joke . She called their resulting forms " Rahaga " , as a mixture of the names " Rahkshi " and " Hagah " . Rahkshi Bios . Guurahk ( Disintegration ) Guurahk is one of the most cunning of the team , and has the ability to divine weaknesses - he ' s able to " see " the stress point in a structure or a foe ' s weakness , and target it immediately . Guurahk ' s staff can shoot a cone of dark energy , disintegrating whatever it hits . Kurahk ( Anger ) Though he is fast and strong enough to down any foe , Kurahk prefers to turn his opponents against each other . His staff can fire rings of anger , causing the target to be consumed by rage . Even the Toa Nuva are not immune to its power , which magnifies any difference of opinion into an all - out physical conflict . Kurahk himself is also often in a rage and is often reckless . His Kraata form is just as angry when exposed . Lerahk ( Poison ) The tip of his staff can poison anything - plants , animals , soil , or any foe he might choose . However , his power does not work over a distance - the staff must be in physical contact with the target . He is not the smartest of the Rahkshi , but he is still strong , fast and cunning and his power is enough to destroy things with ease . Panrahk ( Fragmentation ) This Rahkshi ' s staff sends an arc of energy through the ground or air , which cause the target to explode on contact from short to long ranges . His energies are so potent that the ground under him explodes in a series of tiny bursts , in compliance to his explosive , violent nature . Turahk ( Fear ) Turahk is the Master of Fear . Using his staff , Turahk can induce anything from slight unease to sheer terror in his foes . A being struck by the blast will either run away in panic or remain rooted to the spot in sheer terror . Turahk ' s power is particularly disturbing to the Toa Nuva , heroes that have rarely known fear . Turahk is also the one responsible for killing Jaller , before the latter was revived by Takutanuva . Vorahk ( Hunger ) Stealthy and ruthless in equal measure , Vorahk uses his Staff of Hunger to suck the strength away from his enemies , and use it himself . It is this method of draining that makes him as fierce as he is . He is also the greatest hunter of the Rakhshi . These six breeds of Rahkshi appeared in the game " BIONICLE Heroes " , but the game itself is not canon . Heat Vision ( unnamed ) Personality unknown . Has powers of heat vision but becomes temporarily blind afterward . Yellow in colour . Rahkshi Kaita . Like Toa and Bohrok - Kal , Rahkshi have the ability to merge into Rahkshi Kaita . In this case , a Kaita not only has the powers of the three Rahkshi that formed it , but a unique fourth power . Similarly to the Bohrok - Kal , the Kaita takes its name after the dominant Kraata . So far only two kinds of Kaita have been seen : List of Rahkshi . Although only six kinds of Rahkshi have been given names , there are a total of 42 kinds in existence . Here is a list of each Rahkshi power and its colors :
