Forging#

The Komau was forged in the Great Furnaces of Metru NuiMetru NuiThe city beneath Mata Nui functions as the Great Spirit's brain, housing the Matoran whose labor keeps the god alive. using a specific combination of three Kanoka disk types: Freeze, Weaken, and Remove Poison. The disk blend reflected the mask's mode of action, with Freeze suppressing resistance, Weaken reducing mental defense, and Remove Poison clearing intrusive influences from the target mind.

Powers#
The Komau allowed its wearer to enter the mind of another sentient being and exert influence over thought and action. The effects ranged from subtle suggestion to direct compulsion of physical movement. The mask could also inflict mental pain as an offensive function, producing acute distress capable of incapacitating the target.
The mask was strictly limited by the nature of its target. It could not affect beings without genuine minds, including the VahkiVahkiMetru Nui's mechanical law enforcement squads, designed to maintain rigid order but ultimately undermined by chaos beyond their programming. law enforcers of Metru NuiMetru NuiThe city beneath Mata Nui functions as the Great Spirit's brain, housing the Matoran whose labor keeps the god alive., unthinking RahiRahiThe Rahi were the biomechanical wildlife of the Matoran Universe, built largely by the Brotherhood of Makuta, ranging from background fauna to engineered war beasts. constructs, and other mechanical entities driven by programming rather than consciousness. The boundary was absolute: the Komau required a mind to act upon, and no degree of will could compensate for the absence of one.
Variants#
The Great Komau, available to Toa-class wearers, could sustain control over minds of equal or greater strength for extended periods.

The Noble form was better suited to brief tactical use than to sustained domination.
Both variants shared the same forging requirements and visual appearance, with the Great form distinguished by higher concentration of energized 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. infused during creation.

Limitations#
Beyond the inability to affect mindless entities, the Komau imposed strain on its wearer. Sustained mind control required active focus, and the effort scaled with the target's mental strength. A Noble Komau wearer attempting to control a being of greater mental power could initiate contact but would lose the grip quickly as the target's will reasserted itself.
The mask's use was constrained by ethical custom among Toa, who generally avoided mind control except in cases of direct necessity such as breaking foreign influence on a comrade.
