Composition and the Kanoka Code#

Every Kanoka was a single disc of 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. forged in a mold and stamped on the rim with the symbol of its metru of origin. Three digits engraved on the disk encoded its operational properties: the metru of origin, the basic power locked in by the forging, and the power level on a nine-point scale.

The first digit assigned each metru a flight characteristic intrinsic to its disks. Ta-MetruTa-MetruThe fire district where Ta-Matoran perfected their craft and powered Metru Nui's industry for thousands of years. disks knocked obstacles out of their flight path on impact, although they could not knock Po-MetruPo-MetruMetru Nui's Stone District, home to carvers whose work defined the city and site of an ancient conflict that threatened to divide it. disks. Ga-MetruGa-MetruGa-Metru is a district of Metru Nui, home to the Ga-Matoran and the Bordakh. disks responded to the thrower's mental guidance in flight and could be steered in midair toward a moving target. Po-MetruPo-MetruMetru Nui's Stone District, home to carvers whose work defined the city and site of an ancient conflict that threatened to divide it. disks deflected other disks from their course on contact, a property which gave them their reputation in AkiliniAkiliniAkilini was the principal sport of Metru Nui, played with Kanoka disks on the arena floor of the Coliseum and serving as both civic spectacle and the means by which the worth of a freshly forged disk was tested before mask-making. play. Ko-MetruKo-MetruKo-Metru was Metru Nui's frozen intellectual quarter, home to the scholarly Ko-Matoran race. disks dodged obstacles autonomously on the way to a designated target.

Onu-MetruOnu-MetruThe deep archive-city that made mining and historical records preservation the beating heart of Metru Nui. disks returned to the thrower if knocked off course.

The second digit identified one of the eight basic powers. Reconstitute at Random scrambled molecules and forced a temporary recomposition in randomised form. Freeze encased the target in ice. Weaken reduced structural integrity. Remove Poison neutralised any poison present. Enlarge and Shrink adjusted size. Regenerate repaired inanimate damage. Teleport relocated the target to a randomised destination. Combination disks merged the base powers, the most famous being the Disk of Time, code 199, which carried the only formally numbered ninth basic power.

The third digit measured effective strength. The ceiling for ordinary MatoranMatoranThe most abundant species in the Matoran Universe, chosen by Mata Nui to inhabit and maintain his cosmic body.-made disks was level 8. Only six disks at level 9 had ever existed.

Production and the role of the metru#

Ta-MetruTa-MetruThe fire district where Ta-Matoran perfected their craft and powered Metru Nui's industry for thousands of years. was the city's primary forge district and produced the largest share of disks across all categories. The disks fed directly into the metru's mask-making industry, which depended on raw Kanoka of sufficient quality to forge a KanohiKanohiMasks that grant powers and sustain life, they're the most vital artifact in the Matoran Universe. without the power leeching out during the working. Mask-makers such as VakamaVakamaA Ta-Metru maskmaker transformed into the Toa Metru of Fire, leader of his team through the Visorak war, and Turaga of Ta-Koro for a thousand years. operated forges in the metru and selected disks from the production yards by code, by AkiliniAkiliniAkilini was the principal sport of Metru Nui, played with Kanoka disks on the arena floor of the Coliseum and serving as both civic spectacle and the means by which the worth of a freshly forged disk was tested before mask-making. performance, and by direct inspection.

The other five metru produced disks suited to local industry, each specialised in the flight characteristic of its district. Po-MetruPo-MetruMetru Nui's Stone District, home to carvers whose work defined the city and site of an ancient conflict that threatened to divide it. operated a major disk workshop attached to its carving trades, and the Po-MatoranPo-MatoranThe Stone-element Matoran of Po-Metru and Po-Koro, carvers and quarry workers, the most athletic of the Matoran types and the population behind the Kohlii and Akilini circuits. HewkiiHewkiiHewkii rose from Po-Metru carver to Mata Nui's foremost kolhii player, then served as Toa Inika and Toa Mahri through the late wars of the universe., known in Metru NuiMetru NuiThe city beneath Mata Nui functions as the Great Spirit's brain, housing the Matoran whose labor keeps the god alive. as Huki, ran a shop whose AkiliniAkiliniAkilini was the principal sport of Metru Nui, played with Kanoka disks on the arena floor of the Coliseum and serving as both civic spectacle and the means by which the worth of a freshly forged disk was tested before mask-making.-grade output was good enough that Turaga DumeTuraga DumeThe Turaga of Metru Nui for sixteen thousand years, a former Toa of Fire who saved Lhikan's life and was abducted and impersonated by Teridax. eventually banned the use of Po-MetruPo-MetruMetru Nui's Stone District, home to carvers whose work defined the city and site of an ancient conflict that threatened to divide it. disks by competitors from other metru in tournament play.

The economic loop ran through AkiliniAkiliniAkilini was the principal sport of Metru Nui, played with Kanoka disks on the arena floor of the Coliseum and serving as both civic spectacle and the means by which the worth of a freshly forged disk was tested before mask-making.. A freshly forged Kanoka was passed through trial-grade arena play to determine whether its handling characteristics were strong enough to justify promotion to mask-grade material. A disk that performed well at 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. was sent to the Ta-MetruTa-MetruThe fire district where Ta-Matoran perfected their craft and powered Metru Nui's industry for thousands of years. mask-makers; a disk that performed poorly returned to the forges for melting and reuse. The sport was therefore both the city's principal civic entertainment and a quality-control loop for the entire KanohiKanohiMasks that grant powers and sustain life, they're the most vital artifact in the Matoran Universe. supply.

Compound disks and infrastructure use#

The eight basic powers could be combined through specialised forging into compound disks whose effects merged the parent properties. The craft tables in Ta-MetruTa-MetruThe fire district where Ta-Matoran perfected their craft and powered Metru Nui's industry for thousands of years. used compound formulas throughout the standard KanohiKanohiMasks that grant powers and sustain life, they're the most vital artifact in the Matoran Universe. range: the Mask of Speed from Teleport merged with Reconstitute at Random; the Mask of Shielding from Growth and Regeneration; the Mask of Water Breathing from Regeneration, Shrink, and Remove Poison; the Mask of X-Ray Vision from Regeneration and Teleport; the Mask of Concealment from Enlarge, Shrink, and Freeze; the Mask of Mind Control from Freeze and Weaken.

Disks were also embedded in the city's built infrastructure. Regeneration disks were installed in the structural fabric of buildings so that minor damage repaired automatically. Levitation and Increase Weight disks operated in coordinated pairs to drive airship ascent and descent, and the Air Transit district of Le-MetruLe-MetruThe teal district where Le-Matoran managed everything that moved through Metru Nui, from chutes to airships. relied on the disk-pair principle for the bulk of its lift operations.
