Kanohi

Kanohi were power-imbued masks worn by bio-mechanical beings. Kanohi masks came in many shapes and elements, and had varying powers and levels of power. They were forged using molten Protodermis, or the remains of Kanoka. Many beings, including the Matoran, would die or go into a coma if their masks were kept off for too long.

Powerless Kanohi
Powerless Kanohi were basic Kanohi with no powers. Matoran had to wear them or else they would slowly get weaker, and eventually go into a coma-like state. They were forged from level 6 or lower Kanoka disks, and the power is siphoned off in the forging of the mask.

Noble Kanohi
Noble Kanohi were less powerful versions of Great Kanohi. In addition to Toa, Turaga also wear these masks. They were forged from level 7 Kanoka disks. They are also created when a Toa becomes a Turaga from their old mask.

Great Kanohi
Great Kanohi were worn by Toa and many other powerful beings, such as Makuta and Order of Mata Nui members. They could be forged from level 8 Kanoka disks.

Kanohi Nuva
Kanohi Nuva were Kanohi collected by the Toa Nuva. They possessed greater powers than ordinary Great Kanohi and could also allow its wearer to share its powers with others.

Legendary Kanohi
These Kanohi were very powerful, and sought by many beings. The Kanohi Ignika, the Mask of Creation and the Kanohi Vahi were Legendary.
