Huna

"The problem with invisibility, [Vakama] had discovered, was that he could not see himself either. It was no easy trick to run when he couldn't see his feet."

- Narration, BIONICLE Adventures 5: Voyage of Fear

The Kanohi Huna was the Mask of Concealment. While in its Great form, it gave its user the power to turn completely invisible and grant them visual indetectability, but they still cast a shadow. The only difference between its Great and Noble forms was that the Noble form had a shorter duration of power, unlike the Great, which could last longer. A Huna-wearer could only be detected by someone seeing their shadow or the usage of an Arthron, Elda or Rode.

Huna were carved out of a mixture of the following Kanohi on Metru Nui:
 * Enlargement
 * Contraction
 * Freezing

Example Usages

 * Great: In BIONICLE 2: Legends of Metru Nui, Vakama used his Huna Metru to shroud himself in invisibility to avoid having Makuta Teridax see him.
 * Noble: Turaga Vakama used his Huna to drive the Rahi Nui into a rage and trick it into running into a wall in BIONICLE Chronicles 4: Tales of the Masks.

The Noble Huna was first released in orange in 2001, as part of the Turaga Vakama set. It was also released in the other colors of the Turaga: light blue, tan, dark grey, lime green and light grey, so the other Turaga could wear it. It was also released in the Muaka and Kane-Ra set in the color black, meant to represent an Infected Mask. It was also released in black-and-silver with the Tehutti set of 2004. A blue version was included in the promotional McDonald's Maku set and with her 2003 set as well.

The Great Huna was first released in Vakama's Toa form set in 2004, and was also seen on his Toa Disk. It was later seen in 2005 as the Great Huna﻿ Hordika in Vakama's Toa Hordika form set. In 2006, the 2004 version was re-released with Balta, and later with Sarda in the following year; additionally, two dark green Great Huna Hordika were included as leg armor for Karzahni.
