Kanoka disks were round disks of protodermis used for both sport and defense in the city of Metru Nui. Kanoka disks were made using liquid protodermis that had been purified in Ga-Metru. They were made in every Metru of the city. Each had a special power and was stamped with a three-digit code. The first digit represented the Metru where it was made, the second its power, and the third its level of power.
The Matoran of Metru Nui used special disks for sport and defense called Kanoka disks. These powerful disks were thrown or hurled from powerful disk launchers. Each disk had a three-digit code identifying where it was made, what power it had, and its power level.
A Kanoka disk made in Ko-Metru had the power to dodge obstacles after being launched.
The first digit of a Kanoka disk code identified which metru the disk was made in. The metru of origin determined how the disk flew. The codes were: (1) Ta-Metru, (2) Ga-Metru, (3) Onu-Metru, (4) Po-Metru, (5) Le-Metru, and (6) Ko-Metru. The second digit identified the power of the disk: (1) reconstitutes at random, (2) freeze, (3) weaken, (4) remove poison, (5) enlarge, (6) shrink, (7) regenerate, and (8) teleport. The third digit identified the power level of the disk. Power levels ranged from 1 to 9, with 9 being the highest.
Matoran all over Metru Nui used Kanoka disks for sport and defense.
Each Kanoka disk possessed one of eight special powers that were triggered when the disk struck its target.
Disks were called Kanoka in the Matoran language. Kanoka were a common sight in Metru Nui. They were created in every metru and used primarily for sport, as well as for defense against Rahi. Disks found to be of the right purity and power level were forged into Masks of Power.
Each Kanoka disk had a three-digit code on it. The first digit identified where it was made, the second its power, and third its power level. Ko-Metru disks were made to swerve at high speed to avoid any obstacle.
Matoran throughout Metru Nui used Kanoka disks for sport and as defense against Rahi beasts and the powerful Morbuzakh plant.
Kanoka disks were easy to find in Metru Nui, since every Matoran used them for sport.
Power code 1 was able to reconstitute whatever it touched at random. It was a dangerous disk to use because it was just as apt to make a threat more dangerous than less.
One of the major discoveries to come out of the Ko-Metru Knowledge Towers was the means to create Kanoka disks from liquid protodermis. Working together with protodermis labs in Ga-Metru, scholars perfected the process, and the Kanoka disk rapidly became a part of daily life in Metru Nui.
Kanoka were round disks of protodermis, each with a special power. Each disk was stamped with a symbol of the metru in which it was made and a three-digit code. The first digit related to the metru in which the disk was made, the second its power, and the third its power level. Kanoka disks had many uses, namely sport, defense, and mask making. Disks were used in all sort of games in Metru Nui, including disk surfing, chute boarding, and other sports. Matoran also used disks to fight off Rahi beasts and other threats.
On Metru Nui, Kanohi Masks of Power were made from Kanoka disks. Kanoka with power levels 1 to 6 were made into Matoran masks, because the power leeched away during the mask-making process. Power level 7 disks were made into Noble Masks of Power. Power level 8 disks were made into Great Masks of Power like those worn by Toa. The Great Disks were the only Kanoka with a power level of 9 known to exist.
Kanoka disks were made by pouring purified liquid protodermis into special molds. Often this process was repeated several times before the disk was pronounced done. The nature and level of the disk's power was determined by the properties of the protodermis used, its purity, and the skill of the Matoran making it. Even as of story year 2004, Matoran were still unable to predict just how powerful a disk would be or what power it would have. The metru in which a disk was made determined the flight characteristics of the disk. During the disk-making process, multiple Kanoka could be combined to form disks with totally new powers. In some cases, disk makers knew what the combinations would result in. Other times, it was a case of trial and error.
In addition to being launched and thrown, Kanoka were built into many devices in Metru Nui. Disks of levitation and increase weight were incorporated into Le-Matoran airships, and disks of speed into some ground vehicles. Some newer buildings even had disks of regeneration built into them, so that with the tug of a chain any damage to the structure could be repaired instantly.
Kanoka toss was a highly dangerous street sport played in Metru Nui. One player hurled a Kanoka disk with all his might, while another attempted to catch it. The trick was to catch the disk after it had expended so much momentum that doing so would not trigger its power. This required split-second timing and a lot of courage.
There were three tiers of akilini competition. The lowest rung featured play with power level 1-6 disks, the middle rung with level 7 disks, and the best players were allowed to compete with level 8 disks.
Akilini teams were required by the rules to use only Kanoka disks made in their own metru in tournament play. In particular, non-Po-Matoran using Po-Metru disks was forbidden, as Po-Metru disks were widely considered to be the best in competition. Winning teams' disks were immediately transported to Ta-Metru to be turned into Kanohi masks. This was considered to be a great honor by Matoran athletes.
Kanoka disks were made from purified liquid protodermis. Kanoka disks carved from solid protodermis would have no powers at all.
On Metru Nui, forgery was an uncommon crime, but a dangerous one. A small group of criminals in Po-Metru attempted to pass off disks carved from solid protodermis as Kanoka disks. Purchasers discovered they had disks with no powers at all, often too late to save themselves from the Rahi they were trying to use the disks on. This ring was smashed by the Vahki, although there was concern that others might spring up to take its place as of mid-story year 2004.
Molten protodermis was the raw material that was fed into a forge to be shaped into disks, and later into masks, if the grade of disk was high enough.
Vakama once launched a combination of weakness and reconstitute at random disks to create an explosion.
There were eight basic Kanoka powers: enlarge, freeze, reconstitutes at random, regenerate, remove poison, shrink, teleport, and weaken. These eight powers could be combined in various ways to create new powers. A Kanoka's power and level of power was determined by the properties and purity of the protodermis used and the skill of the Matoran making the disk. The Metru in which it was made also determined the special flight properties of the disk.
Kanoka disks were used in various Matoran sports, including Akilini, and for defense against Rahi. Disks were also made into Kanohi masks. Disks with a power level of 6 or less became Matoran masks and had no power. Disks with a power level of 7 became Noble Masks, with a significant amount of power. Disks with a power level of 8 became Great Masks, with an enormous amount of power. The only disks ever known to have a power level of 9 were the six Great Disks, which were used by Vakama to create the Kanohi Vahi.
In addition to being launched and thrown, Kanoka disks were also used in other ways in Metru Nui. Levitation and increase weight disks were incorporated into the design of airships, and regeneration disks were built into buildings.
Each Kanoka disk had a three-digit code, and the first two digits of the code indicated its metru of origin and its power, or the effect of the disk on its target. The possible powers that Kanoka had were: (1) reconstitutes at random, (2) freezes, (3) weakens, (4) removes poison, (5) enlarges, (6) shrinks, (7) regenerates, and (8) teleports.[3, 16]
A trader on Stelt once had a cracked Kanoka disk in his shop.
It is not known if Kanoka disks were in use outside of Metru Nui, or if the mask-making process elsewhere involved making them from Kanoka disks.
There were eight basic Kanoka disk powers.
- Reconstitutes at random
- Temporarily scrambled the molecules of the target, resulting in a new shape. Scrambled the molecules of the target, resulting in either positive or negative changes.
- Covered the target in a thick coating of ice. Covered the target with a coating of solid ice.
- Reduced the strength of a living or nonliving target. Could be used to bring down structures. Lessened the strength of a target creature or object.
- Removes poison
- Cured the effects of toxic substances. Erased the presence of poison or venom in the target and healed the effects of it.
- Caused the target to grow. Rate of growth was tied to the power level of the disk. Caused the target to grow rapidly. Mazimum size depended on the power level of the disk.
- Caused the target to reduce in size. Rate of shrinkage was tied to the power level of the disk. Caused the target to decrease in size rapidly. Level of shrinkage depended on the power level of the disk.
- Could be used to repair a target, normally a structure or piece of equipment. Rebuilt damaged structures and items.
- Transported the target to another location. Range of teleportation was tied to the power level of the disk. Caused the target to dematerialize and rematerialize at a random location. Distance of teleportation depended on the power level of the disk.
Kanoka disks had different flight properties depending on the Metru where they were made.
- Kanoka from Ta-Metru were stronger and could knock obstacles out of the way.[3, 16]
- Kanoka from Ga-Metru could change direction in mid-air, guided by the thrower's thoughts.[3, 16]
- Kanoka from Po-Metru deflected other disks from their course.[3, 16]
- Kanoka from Ko-Metru dodged obstacles to get to their target.[3, 16]
- Kanoka from Le-Metru flew further.[3, 16]
- Kanoka from Onu-Metru always returned to the thrower if diverted from their course.[3, 16]
