Rorzakh were a type of Vahki who patrolled Onu-Metru.

History

The Rorzakh were the Vahki that patrolled Onu-Metru. They were created, like all Vahki, by Nuparu and their construction was mainly carried out by Po-Matoran.
When Makuta Teridax impersonated Turaga Dume, he made the Toa Metru appear as villains and ordered the Vahki to arrest them. A squad of Rorzakh were responsible for transporting Nuju, Whenua and Onewa to a cell in the Canyon of Unending Whispers. However, the Toa made a run from the Vahki. One Rorzakh managed to use its staff of Presence on Whenua and was able to track him and trap the Toa in a cell.

They were all destroyed when the Visorak invaded Metru Nui.

Traits

They were the most persistent of the Vahki and they would often rather face damage than let a target escape from their clutches. In later model types, Nuparu made several attempts to reduce the sense of 'self damage' that the Rorzakh exposed themselves to.
The Rorzakh would generally rely on their Staffs of Presence to detect a target and to allow them to track them.
