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.

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

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.

Powerless Kanohi
Powerless Kanohi were basic Kanohi with no special powers. Matoran had to wear them or else they would slowly get weaker, and eventually go into a coma-like state. Umbra wore a powerless mask in the shape of a Great Ruru. They were forged from level 6 or lower Kanoka disks.

Infected Kanohi
Infected Kanohi were Kanohi that have been infected by kraata. They were rusted and old-looking in appearance, and the wearer was controlled by Makuta.

Kanohi Nuva
Kanohi Nuva were the Kanohi that had been collected by the Toa Nuva. They possess greater powers than ordinary Great Kanohi masks and can grant their wearer to share its powers with others nearby.

Organic Kanohi
When the Toa Inika came to Voya Nui, their Kanohi were changed by the lightning. They became organic and sentient, so as to help the Toa Inika learn their powers more quickly.

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

Elemental Kanohi
An elemental Kanohi was a Kanohi that allowed the user to use an element. They were usually created from the Toa disk of a Toa that element, but the four most well-known elemental masks, the Vahi, Ignika, Avohkii, and Kraahkan were made in other ways. The only other elemental Kanohi seen in the story was Toa Mahri Hewkii's Garai.
