Orkahm

Matau's chief rival in Metru Nui was a Matoran named Orkahm. Where Matau was cocky and reckless, Orkahm was responsible and careful. He was a Ussal Crab rider like Matau was, but tended to possess more control. His favorite Ussal Crab was Pewku (who later became a pet to Onepu, and then Takua). His favored Kanoka Disk was a level 4 Regeneration disk.
