In battle, separation from a mask becomes catastrophic.
These masks are forged through a process involving molten 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., the MatoranMatoranThe most abundant species in the Matoran Universe, chosen by Mata Nui to inhabit and maintain his cosmic body. Universe's most versatile substance. An alternate method shaped Kanohi from Kanoka discs, the spinning projectiles that normally served as weapons. Both approaches could imbue the mask with special powers, from simple enhancements to extraordinary abilities that define their wearers. The process of creating power-granting Kanohi remains mysterious, guarded by craftsmen and shrouded in tradition.

Some Kanohi exist in only one copy, forged for singular purposes or as legendary artifacts. Each Kanohi's power is as unique as the hero who wears it.
Color and Adaptation#
Most Kanohi share an unusual property when worn. A freshly forged mask appears dull silver-grey, but once activated it shifts color to match the wearer's armor. This chromatic adaptation makes the mask feel like an integrated part of the wearer rather than external equipment.
