De-Matoran

De-Matoran or Matoran of Sonics were Matoran with innate sonic powers. They did, however, possess 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 that are 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.

Location
A village in the Tren Krom Peninsula

Trivia
