"Then he triggered his mask power, reaching into the mind of Matau. As a crafter, he knew just when a hammer was needed and when a more delicate tool would get the job done. He carefully applied the mask-energies to drive out the Vahki's influence."
— Narrator, Voyage of Fear

Title Mask of Mind Control
Powers Controlling the minds of others
Component disks Freeze
Remove Poison
Bearers Onewa
Pronunciation koh-MAOW[1][note 1]

The Kanohi Komau is the Mask of Mind Control. It allows its user to see into the mind of another and to control them, but only if the user has greater willpower than the target.[2][3] The less willpower a target has, the easier it is to control them.[4] It can only work on one target at a time.[5] The Noble version cannot control beings who are as mentally strong for as long a time as the Great version can.[6][7] The Noble is strong enough to control Krana,[8] but not Toa.[9] Both versions can be used to deliver mental blasts with effects debilitating, but not known to be lethal, to their targets.[10][11] Because the mask only works on beings with minds, it is useless against robots like Vahki[12] and most types of Rahi.[note 2] It also does not work on Spherus Magna natives.[22][23]

On Metru Nui, Kanohi Komau are made from Freeze, Weaken, and Remove Poison Kanoka.[24]

Set Information

The noble Komau was first released in 2001 as part of 8542 Onewa in tan and 8539 Manas in yellow. It was one of the masks possible to be received in 8525 BIONICLE Masks, in orange, lime green, tan, light blue, light gray, and dark gray. It was made available in copper, representing a Copper Mask of Victory, through promotional means. In 2004, it was released as part of 8608 Vhisola in dark blue dual-injected with silver. The mask bears the code 6-AG on the inside.

The Great Kanohi Komau was released in light brown in 2004, as part of set 8604 Toa Onewa, and in 8721 Velika in 2006.

A Hordika-version of the mask was released in light brown as part of 8739 Toa Hordika Onewa in 2005.


  • Copper Masks of Victory are often made in the shape of a Noble Komau or a Noble Huna.
  • Despite being a mask that robs a target of their free will, the Komau is not considered to be an immoral mask because it has the capability of being used for good, depending on the morals of the user.[26][27][28]
  • Despite Kivi and Nuhrii being traditionally featured with a Kaukau in Mata Nui Online Game II: The Final Chronicle, this was caused by a typo in the game code. Kivi and Nuhrii were accidentally programmed to wear a "Kamau," and because the game couldn't recognize this as being the "Komau" which it had a sprite for, the two Matoran were given the game's default mask, the Kaukau. Peter Mack has since confirmed that only Hahli was intended to wear the Kaukau in the game.[29]

  1. The pronunciation provided in Encyclopedia Updated is koh-MOW, but koh-MAOW is written here instead since it is less ambiguous.
  2. Although it has been stated to not be able to control most Rahi,[1][13][14] the Komau has been shown to control Nui-Kopen,[15] Kane-Ra,[16] Rahi Nui,[10][11] Troller,[17] and most likely Lohrak,[17] Nui-Jaga,[18] and other unknown Rahi.[19][20] It is also possible that the Komau can control Rahi with Infected Kanohi.[2][21]
