The Destiny Rule#
The energized-protodermis rule was the most significant finding to come out of the labs. The substance transformed any being whose destiny was to be transformed, and killed any other being it contacted in sufficient quantity. The rule shaped subsequent understanding of 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. across the Matoran UniverseMatoran UniverseA civilization of biomechanical beings living inside a colossal robot, destroyed when Teridax seized control..
The clearest demonstration came during the transformation of the Toa MataWho are the Toa Mata?Six warriors built to order by Artakha, stored in canisters, dropped into the ocean. This is the origin story of Bionicle's heroes and why their first week of work was entirely amnesiac. into the Toa NuvaToa Mata and Toa NuvaSix biomechanical heroes created by the Great Beings to awaken Mata Nui and defeat the Brotherhood, transformed once and tested across an entire age..

All six emerged transformed and intact, confirming under the lab's documented rule that each had been destined for the change.
A counterpoint appeared during the Toa 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.'s journey through hostile territory, when OnewaOnewaOnewa served as Toa Metru of Stone, led Po-Koro through the Dark Time, and constructed the Metru Nui statue honoring the fallen Toa Mahri Matoro. was struck by a drop of energized protodermis. He neither transformed nor died. The exposure was consistent with the lab's documented rule: a drop did not constitute full immersion, and the substance's transformative effect required sustained contact with a destined recipient.

Frequently asked questions
- What were the Protodermis Labs?
- The Protodermis Labs were a research facility in Ga-Metru, the city of learning within Metru Nui. Ga-Matoran scholars working there studied the properties of protodermis and documented their results.
- What was discovered at the Protodermis Labs?
- The labs were where the canonical rule governing energized protodermis was first documented: the substance would transform a being if transformation was its destiny, and would kill it otherwise. This destiny rule shaped subsequent understanding of protodermis across the Matoran Universe.
- How was the destiny rule demonstrated?
- The clearest demonstration came when the Toa Mata sank into tubes of energized protodermis after sealing the Bahrag, and all six emerged transformed and intact as the Toa Nuva. A counterpoint came when Onewa was struck by a drop of energized protodermis and neither transformed nor died, consistent with the rule that the transformative effect required sustained contact with a destined recipient.
- How did the Brotherhood of Makuta use the destiny rule?
- The destiny rule first surfaced by Ga-Matoran scholarship later formed the basis for the Brotherhood of Makuta's experimental programmes, including the Rahkshi-creation processes documented in The Mutran Chronicles. The Brotherhood did not discover the rule; it weaponized one already on the books, and the Matoran scientists who first published it were not credited.
- What happened to the Protodermis Labs after the Great Cataclysm?
- Like the rest of Metru Nui, Ga-Metru was damaged in the Great Cataclysm and repaired 1,001 years later by the Staff of Artakha during the operation undertaken by the Toa Nuva. The labs, as one of the listed Ga-Metru locations, were later abandoned again once Spherus Magna was reformed and the Matoran population relocated.
