Vorzakh

Vorzakh of Le-Metru don't have the patience for long chases. They would rather just smash everything in their path until they find the Matoran they are searching for. Their Staffs of Erasing can temporarily eliminate a target's higher mental functions, leaving only their motor functions intact; Le-Matoran have gotten used to seeing these sorts of victims, known as "shamblers".

All of the Rorzakh were destroyed in the Great Cataclysm.
