Kanohi

"You must not remove your masks, unless you are replacing one with another. Without them, your strength is halved."

- Toa Helryx, BIONICLE Legends 10: Swamp of Secrets

Kanohi were power-imbued masks worn by bio-mechanical beings in the Matoran Universe. Kanohi came in many shapes and elements, and had varying powers and levels of power. They were forged using molten Protodermis or Kanoka. Matoran and Turaga would die or go into a coma if their masks were kept off for too long, while Toa and other powerful beings would be severely weakened if their Kanohi were removed. Makuta in particular relied on their Kanohi to contain their Antidermis.

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. This type of Kanohi were forged from Kanoka with a power level of 6 or lower, as the power was siphoned off in the forging process.

Noble Kanohi
Noble Kanohi were masks that contained powers, although they were less powerful than Great Kanohi. In addition to Toa, Turaga regularly wore these masks. They were forged from level 7 Kanoka disks. They were also created when a Toa became a Turaga, from the Toa's original Kanohi.

Great Kanohi
Great Kanohi were masks with powers on a greater level than Noble Kanohi. They were worn by Toa and other powerful beings, such as the Makuta species and Order of Mata Nui members. They could be forged from level 8 Kanoka disks.

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

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