Power and function#
Farshtey's online answers set out how the mask works. It lowers the wearer's density until they become intangible, letting them pass through objects and avoid attacks. While intangible the wearer is lighter than air, so they don't sink through the ground and can even drift above it, and they move in silence. The mask cannot make anyone other than its wearer intangible. These are the writer's later comments, not events in a published story. (Writer's later comment, not a published story)
He also compared the mask to the density control power of the MakutaMakuta (Species)Shadowy Antidermis beings and the Brotherhood's elite, Makuta commanded darkness and shaped the Matoran Universe's fate., saying it works the same way. The comparison is useful shorthand, but it too comes from his answers rather than from a book or serial. (Writer's later comment, not a published story)

Farshtey's answers make her the wearer of the Great Mask of Intangibility, worn from her days as a Matoran onward. No published story shows her using it.

The mask does appear in Dark MirrorDark MirrorThe 2008 podcast serial in which Takanuva, thrown off course by a damaged Olmak, lands in a universe where Tuyet kept the Nui Stone and the Toa rule the Matoran by fear., which takes Takanuva into an alternate universe where Tuyet rules a Toa Empire. In that universe's Metru NuiMetru NuiThe city beneath Mata Nui functions as the Great Spirit's brain, housing the Matoran whose labor keeps the god alive., a huge monument of the Mask of Intangibility stands in honour of the empire's leader. It is the mask's one appearance in the story, and it belongs to an alternate reality rather than the main timeline. (Dark Mirror)
Later bearers and parallel powers#
No other wearer of the Mask of Intangibility is recorded. Farshtey also allowed that a separate Mask of Density Control might exist, without saying how it would differ from this one. (Writer's later comment, not a published story)
Frequently asked questions
- What is the Mask of Intangibility in Bionicle?
- The Mask of Intangibility is a Kanohi that lets its wearer become intangible by lowering their density, so they can pass through objects and avoid attacks. Its powers are described in writer Greg Farshtey's online answers rather than in a story.
- Who wore the Mask of Intangibility?
- Farshtey's answers name the Toa Mangai Tuyet as its wearer. In the serial Dark Mirror, set in an alternate universe ruled by a Toa Empire under Tuyet, a huge monument of the mask stands in Metru Nui.
- How did Tuyet use the Mask of Intangibility?
- No published story shows Tuyet using the mask. Dark Mirror only shows its monument in the alternate Metru Nui, raised because of the mask's link to the empire's leader.
- What were the limits of the Mask of Intangibility?
- Per Farshtey, the mask can only make its wearer intangible, not other targets. While intangible the wearer is lighter than air and moves silently. None of this is shown in a story.
- Did anyone else have intangibility powers like the Mask of Intangibility?
- Farshtey said the mask works like the density control power that Makuta possess. That comparison comes from his online answers, not from a story.
