Ahkmou

Ahkmou was a Po-Matoran, one of the six Matoran who knew the location of a Great Disk, servant of Makuta and Onewa's long-time rival. He was originally completely brown, and wore a Kanohi Rau mask. On Mata Nui, he wore a black Rau. Makuta believed him to be the destined Toa Metru of Stone.

Personality
Shifty and devious, Ahkmou always sided with whomever he thought would get him ahead. Involved in a number of schemes and power-grabs by those on the evil side, he had a certain wit or "knack" for not being caught. He egotistically thought himself to be more important than anyone else. Ahkmou's main occupation was a carver, and as such, he carried a level 3 regeneration Kanoka Disk to repair mistakes made while carving. Later in his life, he would become a trader.

Metru Nui
Ahkmou was the Matoran Nidhiki chose to help gather the Great Disks, because of his shady tendencies. Toa Metru Onewa sought out Ahkmou and found him "trapped" on a sculpture in the Po-Metru Sculpture Fields. After the Toa Metru had gathered all of the Matoran who knew the locations of the Great Disks, they determined that Ahkmou was a traitor.

Ahkmou later accompanied Vakama, Onewa, and Nuhrii to find the Ta-Metru and Po-Metru Great Disks, and went with the Toa Metru to the Great Furnace to face the Morbuzakh. There, he and five other Matoran became a Matoran Nui briefly to aid the Toa Metru. Afterwards, he snuck off and was eventually put in a Matoran Pod.

His pod was one of the first six that the Toa Metru took to Mata Nui, but during the events of BIONICLE Adventures 5: Voyage of Fear, it was lost and sunk underwater in a cave. Makuta eventually awakened him and told him of Metru Nui.

Mata Nui
Unlike the rest of the Matoran, Ahkmou remembered Metru Nui, as he was awakened by Makuta and not the Turaga, and informed thus. It was at this time that Makuta forced Ahkmou into working for him. During the short time of his career as a trader, he was the Po-Matoran seller of Comet Balls, a scheme devised by Makuta under the cover of a new type of Kolhii ball to infect the Matoran of Po-Koro. Takua stole Ahkmou's key to the source of the balls, but Ahkmou himself was not caught. He continued as a merchant in Po-Koro well into the days of the Mask of Light, though slightly more cautious.

Ahkmou returned to Metru Nui with the other Matoran and helped to repair it.

Scams
During the thousand years Ahkmou was on the island of Mata Nui, he pulled off two known scams:
 * His first scam was selling "lucky" Ghekula to superstitious Matoran, but Turaga Onewa eventually put a stop to that.
 * His second scam, and his most well-known one, was the Comet Ball exploit, which infected most of Po-Koro.
