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 an 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.
