The Vahki

Metru Nui’s robotic order enforcement squads, the Vahki were built by Matoran to police the city. This they do very efficiently, protecting Matoran from Rahi attacks and making sure the work of the city gets done. They are relentless, cold, and never give up on a chase. Each of the six types of Vahki are equipped with stun staffs which affect the minds of their targets, making it easier to pacify lawbreakers.
