So here's a list of facts related to Antidermis:
1. They make Matoran suceptible to suggestions.
2. The Makuta were made up of this substance.
3. Brutaka's species, when taking in Antidermis (at least, in liquid/gaseous form), can become more powerful or even get "possessed" by the Antidermis.
4. The Antidermis, like the Energized Protodermis, is sapient and apparently has some knowledge of Mata Nui's mission.
My Theory: Mata Nui intended that the Makuta species would eventually "expires" and turn into the gaseous Antidermis, and for good reasons:
A. Teridax, whose destiny is to control the other robot, can easily access to the robot's "mind", and;
B. The "expiration" time of the Makuta would be an indication of that something went wrong for Mata Nui's mission and he is taking longer time than he originally thought he needed to accomplish his task(s), and thus needed a better "body" condition. And since his system is made up of Matoran as his "cells", he would need them to work harder. The Makuta, who were told by Miserix to oversee parts of MU, would turn into gaseous Antidermis (and lose their will) and since their armor wasn't designed to hold Antidermis, would eventually cause an Antidermis leak into the MU, thus infecting the Matoran. Brutaka's species would be infected as well, and would eventually get possessed by the Antidermis, who would then command the Matoran on how to improve their work as cells of MN.
But what happened was that when the day the Makuta turned into the gaseous Antidermis, Mata Nui was taken down; as a result, MN cannot interfere even if the Makuta were to take actions to adapt to the changes and thus nothing happened (probably within Teridax's calculations).
Now come and find holes in my theory
