Ahkmou

Ahkmou was Onewa rival back in Metru Nui. Shifty and devious, Ahkmou is the Matoran, Nidhiki chose to help gather the Great Kanoka Disks. Ahkmou is a carver, and thinks himself to be more important than anyone else. He carries a level 3 regeneration Kanoka Disk to repair mistakes made while carving. He always sides with whomever he thinks will get him ahead. Unlike the rest of the Matoran, Ahkmou remembers Metru Nui, as he was awakened by Makuta and not the Turaga, and Makuta filled him in.

Makuta believed him to be the destined Toa Metru of Stone. He was originally completely brown, and wore a Kanohi Rau mask.
