Shadow Matoran

A Shadow Matoran is a Matoran who has had all of his/her Light drained out, making them corrupt and evil, and replacing their Element with the Element of Shadow. Currently, only the Shadow Leeches are known to be capable of doing this.

Any type of Matoran can be mutated into a Shadow Matoran, and once it happens, the Matoran loses its natural Element-related ability. The Matoran would also lose its natural colors. If transformed into a Toa, the Matoran would still retain its Shadow Element.
