The Matoran Language

The Matoran Alphabet

Matoran is the language and writing system used by the Matoran and many other races of the BIONICLE universe.

Matoran Alphabet[]

The Matoran alphabet is similar to the English alphabet, being a simple substitution cipher. In Mata Nui and Metru Nui, the letters and numbers are circular symbols. On Voya Nui and a secret laboratory on Bara Magna, these symbols are hexagon-shaped, but are otherwise identical, except for "K", which was identical at first, but was later changed to the rotated "Y" shape that it now has.

Matoran Words[]

For the most part, the Matoran language is translated into English for our benefit. However, several terms usually remain untranslated (this list assumes that names of Kanohi masks are direct descriptions of their powers):

Slang and Miscellaneous Terms[]

  • "Akilini-head" or "Kolhii-head" - a mild insult
  • "Crosswired" - a derogative term used to suggest that someone is crazy.
  • Bioquake - earthquake
  • ____bones: To die as a result of something. Example: "Why did you get so close to the volcano? You could've been lava-bones!"
  • "Brakas" - an insult referring to the insulted party's intelligence
  • "Dermis Shell Weather" - Unpleasant weather conditions; referring to how Dermis Turtles can sense bad weather a few days ahead.[2]
  • "Mata Nui" - an exclamation of surprise. In English it translates to "Oh my god".
  • Spiriah - Failure
  • Roodaka - Treachery
  • "Go to Karzahni!" - an insult
  • "Manas Zya" - a vocal command Hydraxon used when he needed Spinax to attack someone


All sentient beings in the Bionicle universe use a special measuring system. There are three different units of length: the Bio, the Kio, and the Mio; comparable to the Earth units of Meters and Kilometers. A Toa is 1.6 Bios (7.2 Feet) tall.

  • Bio - The smallest measurement used in the Bionicle universe. A bio is approximately equal to 4.5 feet or 1.37 meters in Earth measurements.
  • Kio - A kio is the middle sized measurement in the Bionicle universe; equal to 1000 bio. Or, 4500 feet/0.85 miles, 1371 meters/1.37 kilometers in human measurements.
  • Mio - A mio is the largest measure of distance in the Bionicle universe that we know of. It is equal to 1000 kio. Or, in human terms, 850 miles or 1370 kilometers.

For other units of measurement, such as lengths of time, Earth units such as hours and days are used. Sometimes Earth units of length are used in place of the Bionicle units above, so that the reader may understand easier.

Chutespeak and Treespeak[]

Two names for slang used almost exclusively by the Le-Matoran of Metru Nui (though the occasional outsider has picked it up). "Chutespeak" was its name in Metru Nui and "Treespeak" was used on Mata Nui. Chutespeak/Treespeak terms are made by combining two or more words into one, similarly to the real-world Anglo-Saxon practice of kenning.
