Kra

Kra- was a Matoran prefix meaning "shadow". When used, it denoted that the object of its reference was associated with shadow and/or the Element of Shadow in particular; the prefix could also be incorporated into names.

Shadow Matoran did not use this prefix, due to not seeing themselves as a "tribe" like other Matoran types.

Usages

 * Kanohi Kraahkan - Mask of Shadows

Trivia

 * The prefix "Kra-" was retroactively derived from "Kraahkan," the name of the Mask of Shadows.
