An idea that was always creeping in the back of my mind recently resurfaced.
The Great Disks. We know that the six Metrutoran wanted them for their own selfish reasons, but Nuhrii is an interesting case.
It is said that he wanted to outdo Vakama by forging the Ta-Metru Great Disk into G1 equivalent of the mask of ultimate power. Of course, he never had a chance to do so. But what if he did? What kind of mask would this result in?
Luckily, we know the powers for all of the Great Disks, so we can ask this question for all of them. Let’s start with…
Ta-Metru: code 159, power: enlarge
Result: If Nuhrii proceeded with his original plan, he would have made a Legendary Mask of Growth.
Predicted powers: allows the user to grow to the size of the Matoran Universe
(GSR), destruction would stop all growth inside MU.
Note: One could obviously rival Mata Nui with such mask.
Ga-Metru: code 279, power: regeneration
Result: Legendary Kiril
Predicted powers: Regenerative power most likely rivaling, or surpassing that of the Staff of Artakha (could reach even Karda Nui), destruction would result MU inhabitants to be unable to repair anything. Universe would eventually break down from accumulated damage.
Note: If this mask was created instead of Vahi, Great Cataclysm could have been reversed immidiately after Makuta’s defeat. Great rescue wouldn’t needed happen, Visorak army would never had taken over Metru Nui, Makuta would have remained trapped, GSR proceeds to repair SM.
Po-Metru: code 339, power: weaken
Result: Legendary Jutlin
Predicted powers: Reverse of Legendary Kiril, its use decomposes entire MU in relatively short time, if destroyed all erosion and material degradation would cease.
Note: OoMN might want to use it to “end all” during Teridax’s reign. Teridax might want to smash it to immortalize his new body. Whoever owns it has a superweapon in their hands (on their face?)
Ko-Metru: code 429, power: freeze
Result: Legendary Mask of Ice
Predicted powers: Provides elemental ice powers surpassing element lord of ice, destruction screws up laws of thermodynamics, which causes MU to build up heat, until it is cooked from inside out.
Le-Metru: code 589, power: teleportation
Result: Legendary Kualsi
Predicted powers: Ability to transport oneself or others anywhere within the MU without any limitation, or over interplanetary distances (if Artakha’s attempt is any indication), destruction would disable all teleportation powers/devices, causing them to either not function at all, or have extremely random results.
Note: Destruction surprisingly wouldn’t be that devastating. The maximum distance is hard to gauge, but it shouuld be at least greater than Artakhas.
Onu-Metru: code 619, power: reconstitute at random
Result: Legendary Mask of Mutation (? - my guess)
Predicted powers: Gives user free control over any physical form and its properties. Can also reverse any mutation. Destruction negates all shapeshifting, mutation, or other transformative proceses inside MU, this might impair some essential GSR functions where such process is needed (such as the constant transformation of the power source providing energy for the universe).
Note: Possibly the most powerful mask.
Conclusion: Vakama, why didn’t you just make Legendary Kiril instead of Vahi !?
