Orkahm

Orkahm is a Le-Matoran.

Metru Nui
Orkahm was Matau's chief rival in Metru Nui. Where Matau was cocky and reckless, Orkahm was responsible and careful. He was an Ussal rider like Matau once was, but tended to possess more control. His favorite Ussal crab was Pewku. He favored a Level 4 Regeneration Kanoka, which he used to fix Chutes. After leaving the other Matoran in the Great Furnace, Orkahm was captured by Vahki and placed into a Matoran Pod on Makuta's orders.

In Time Trap, Makuta made Vakama believe that Orkahm was a Toa in his illusion.

Mata Nui
On Mata Nui, Orkahm's name was changed to Orkan under unknown circumstances, and he was a member of the Gukko Force. He has since returned to Metru Nui and is helping to rebuild it.
