Origin and classification#

Each disk was forged from purified ProtodermisProtodermisThe engineered substance building the Matoran Universe, protodermis exists in countless refined states from mundane metal to diamond-hard crystal to the destruction-or-transformation force of energized form., stamped with the symbol of its home MetruMetruIn the Matoran language a metru was a single district of Metru Nui; the city was divided into six such districts, one for each element, and the term covered both the place and the elemental community that lived in it., and engraved with a three-digit Kanoka Code. The first digit recorded the district of manufacture. The second recorded one of eight standard powers, ranging from Reconstitute at Random through Teleport. The third recorded the disk's power level, on a scale that ran from one to eight for ordinary disks.

Six disks existed at a power level of nine. They were classified separately as Great Kanoka, or Great Disks. No other power-nine Kanoka had ever been produced or recovered. Their origin was not recorded as a single forging event in the canonical sources. Each was simply present in its district, lodged in terrain or in a structure, treated by the local MatoranMatoranThe most abundant species in the Matoran Universe, chosen by Mata Nui to inhabit and maintain his cosmic body. as a relic of unknown manufacture rather than as standard inventory.

The disks shared the standard Kanoka properties of their districts of origin.

The power-nine rating meant that each disk's effect was significantly more durable and longer-lasting than any other Kanoka of its kind.

The first digit identified the district. The second indicated the disk's combined or assigned power. The third confirmed the power level of nine.

Each location was sufficiently hazardous to deter casual retrieval. The collective effect was that no MatoranMatoranThe most abundant species in the Matoran Universe, chosen by Mata Nui to inhabit and maintain his cosmic body., and no single ToaThe Toa: Heroes of the Matoran UniverseThe Toa were biomechanical guardians sworn to protect the Matoran, bound by a strict code and defined by sacrifice across every age of the universe., could have recovered all six on their own. The disks required a coordinated team with elemental coverage across fire, water, stone, earth, ice, and air.

Use against the King Root#

The recovery campaign was conducted under direct pressure from the MorbuzakhMorbuzakhA sentient plant monster created by Teridax to terrorize Metru Nui and control its population through fear.. The plant creature was actively choking the city. Its vines had killed MatoranMatoranThe most abundant species in the Matoran Universe, chosen by Mata Nui to inhabit and maintain his cosmic body., collapsed structures, and continued to drive the surviving population toward the ColiseumThe ColiseumCentral tower of Metru Nui, serving as government seat, sporting arena, and, during Teridax's masquerade, a prison for the city's Matoran population. as part of its directive from TeridaxTeridaxTeridax orchestrated a thousand-year scheme that ended with him occupying the Great Spirit Robot itself before his death on Bara Magna.. The VahkiVahkiMetru Nui's mechanical law enforcement squads, designed to maintain rigid order but ultimately undermined by chaos beyond their programming., the standing law-enforcement squads of the city, had failed to contain the vines through ordinary means.

Once all six disks had been gathered, the team convened. VhisolaVhisolaVhisola was a Ga-Matoran student of Nokama, one of the six finders of a Great Disk, whose research deduced the location of the Morbuzakh King Root. reported the result of her research on the MorbuzakhMorbuzakhA sentient plant monster created by Teridax to terrorize Metru Nui and control its population through fear.'s biology: the creature was controlled by a single central root system, the King RootThe King RootThe sentient central core of the Morbuzakh plant, grown in the Great Furnace of Ta-Metru and destroyed by the Toa Metru using the fused Great Disks., from which all vines extended. Cutting off the King Root from its vines would kill the creature. NokamaNokamaNokama served as Toa Metru of Water, endured the Hordika mutation, and led Ga-Koro and later Ga-Metru as Turaga through three eras. deduced that the King Root had to be located in the Great FurnaceThe Great FurnaceThe largest furnace in Ta-Metru, site of the Morbuzakh King Root's nest and the recovery of the fused Great Disks that became the Kanohi Vahi., the largest heat source in the city. The team and the six MatoranMatoranThe most abundant species in the Matoran Universe, chosen by Mata Nui to inhabit and maintain his cosmic body. finders moved on the Furnace.

MetruMetruIn the Matoran language a metru was a single district of Metru Nui; the city was divided into six such districts, one for each element, and the term covered both the place and the elemental community that lived in it. spent most of their available elemental energy fighting the vines that filled the building, eventually drawing the MorbuzakhMorbuzakhA sentient plant monster created by Teridax to terrorize Metru Nui and control its population through fear. in closer by taunting it. When the King Root was within range, the team launched the six Great Disks in combination. The disks formed an energy bubble around the King Root, isolating it from its vine network. Cut off from its central organ, the plant creature died. The vines throughout Metru NuiMetru NuiThe city beneath Mata Nui functions as the Great Spirit's brain, housing the Matoran whose labor keeps the god alive. disintegrated. The Toa MetruToa Metru and Toa HordikaSix Matoran elevated by Lhikan to save their city, mutated by Visorak venom, and restored in time to deliver the population to safety. retrieved the six disks intact and fled the collapsing Furnace.

The use of the combined disks against the King Root remained the only recorded instance of all six Great Disks being deployed in their original disk form. After the MorbuzakhMorbuzakhA sentient plant monster created by Teridax to terrorize Metru Nui and control its population through fear.'s defeat, they were never again used as projectiles.

The fusion was one-way. The six individual Great Disks ceased to exist as separate objects from that point onward. Their substance and power were carried entirely within the structure of the Vahi.

Legacy#

The Great Disks had three lasting consequences. The first was operational. Their recovery proved the Toa MetruToa Metru and Toa HordikaSix Matoran elevated by Lhikan to save their city, mutated by Visorak venom, and restored in time to deliver the population to safety. capable of coordinated work across the entire city in the face of active MorbuzakhMorbuzakhA sentient plant monster created by Teridax to terrorize Metru Nui and control its population through fear. and VahkiVahkiMetru Nui's mechanical law enforcement squads, designed to maintain rigid order but ultimately undermined by chaos beyond their programming. interference and welded the team together as a functional unit.

The six finders themselves carried a further legacy beyond the disks.

The six finders never became Toa, but the parallel between the two sets of six names was preserved in the record.
