This was originally designed for canon contest.
“You and I have been friends for thousands of years. We’ve traveled together, fought together, and once almost died together.”
— Lhikan to Tuyet, The Many Deaths of Toa Tuyet
Since Tuyet and Lhikan are comrades and members of Toa Mangai, I guess they should have very similar looks like the toa metru, at least their masks should be the same style.
Other than that, I noticed some dramatic similarities between their mask power. For example, the mask of intangibility and the mask of shielding both provide protection to the user, Hau allows its user to generate a force field, conversely, the mask of intangibility allows its user to become intangible so they can avoid attacks. In my opinion the mask of intangibility is a corrupted Hau.
I took inspiration from the pharaoh, the cobra, the mask of control, and many masks by khingk and others
A more intuitive contrast between Hau and the mask of intangibility
I didn’t make a 3d model when I was drawing so it’s not very accurate. Anyway, hope you all like it!
