De-Matoran

De-Matoran were Matoran with innate Sonics powers. They possessed a very minuscule amount of Elemental Sonics energy, to the extent that they have more acute sense of hearing than any other type of Matoran, being able to hear sounds kio away. As a result, they trained themselves to make as few sounds as possible and generally did not welcome Toa, as Toa often bring conflict and battle, which caused excessive noise.

Trivia

 * The prefix "De" comes from the word "decibel".
 * Krakua was a de-matoran.
