Ahkmou

Ahkmou was a traitorus Matoran who knew the location of a Great Disk.

Metru Nui
On Metru Nui, Ahkmou always came second to everything compared to Onewa. One day, he ran into ex-Toa and Dark Hunter Nidhiki. They made a deal. If Ahkmou got the great disks, Nidhiki would leave him alone.

Ahkmou was found on top of a large sculpture in Po-Metru when Onewa rescued him. He journeyed to the Great Temple with him and to the Fire Pits with Vakama and Nuhrii also.

He also guided the two Toa Metru to the Sculpture feilds, where Onewa found his great disk.

When all 6 Toa and all 6 Matoran went to Ta-Metru for the final battle with the Morbuzahk, Ahkmou formed into the Matoran-Nui along with Nuhrii, Vhisola, and the rest. When they demerged, Ahkmou ran off. He was captured by a Vahki and stuffed into a Matoran Pod.

When the Toa Metru fled from Metru Nui, Ahkmou's pod fell out of the Vahki Transport that Matau was driving. Makuta later rescued him.

Quest for the Masks
During the Toa's quest, Ahkmou sold Comet Balls. What Po-Koro didn't know is that they were infected, similar to the Infected Masks. Ahkmou tried to sell a ball to Takua, but the chronicler didn't have enough money. When he was found out and Pohatu went on his way to the Koro, Ahkmou fled and stated he had "gone fishing". He later returned to Po-Koro, and continued to sell Koli Balls. But this time, they were safe to use.
