Order of Mata Nui The Order of Mata Nui was an organization from the first iteration of the BIONICLE theme , so called because of their dedication to the will - as they saw it - of the Great Spirit Mata Nui . History . Originally this organization - or a similar one with several of the same members - existed under the name Hand of Artakha , and preceded the Toa as the defenders of the universe inhabited by the Matoran and other beings . When the Toa came into being , several members of the Hand of Artakha formed the Order of Mata Nui to serve as a secret society who would guard the universe unseen and through means that the more heroic Toa couldn ' t employ . They would thus act in secrecy for tens of thousands of years , checking the actions of the villainous Brotherhood of Makuta and the Dark Hunters while maintaining their status in hiding . Among the actions taken by them was placing guards over the Ignika , the Kanohi Mask of Life ; maintaining a prison to which the worst criminals in the universe were forever condemned ; and planting evidence on Metru Nui indicating that the Matoran who became the Toa Metru had been wrongly selected , though this was in fact a ploy to trick Teridax . Eventually the Order of Mata Nui came out of hiding in order to engage the Brotherhood in open war , and demonstrated their moral ambiguity further by allying with the Dark Hunters and other villains in order to address the threat of the Makuta . They struck a series of blows against the Brotherhood , but failed to stop Teridax from seizing control of the universe . He then destroyed their home base , resulting in the deaths of most of the Order members ; the remainder joined in resisting Teridax ' s occupation before emigrating to Spherus Magna following Teridax ' s demise . Prominent Members . Helryx . The first Toa ever created , a Toa of Water who led the Hand of Artakha before forming the Order of Mata Nui ; due to the nature of the Order she chose to hold herself above the Toa code , which among other things prohibited Toa from killing their enemies except under extreme circumstances . She wielded a mace and shield and wore the Mask of Psychometry , which gave her the power to determine where an object had come from . She led the Order for millennia and later commanded their entrance into open war , only to end up trapped inside the brain of the Great Spirit robot after Teridax took it over . Eventually she and several other inhabitants of the robot were ejected into space and then brought to Bota Magna by Vezon , where they met one of the Great Beings . Axonn . An axe - wielding warrior who was part of the Hand of Artakha ; after that group was dissolved Axonn briefly went on a spree of conquest before being recruited to the Order . He was eventually assigned to Voya Nui as one of the protectors of the Mask of Life . Botar . A monstrous member of the Order whose primary task was taking dangerous criminals to the Pit , a maximum security prison , after they had been defeated in battle . He was later killed by Makuta Icarax , but was one of several characters revealed to have been revived aboard the Red Star . Brutaka . A sword - wielding former scholar and former servant of the Brotherhood ; he befriended Axonn and the pair were assigned to Voya Nui together , but over time Brutaka came to believe that Mata Nui had forsaken them . Hydraxon . A weapons master who served in the Hand of Artakha before joining the Order ; he was responsible both for recruiting his old comrade Axonn and for training the Toa Mata after they were created . He was subsequently assigned to the Pit as its jailer , but was killed during a mass breakout resulting from Mata Nui falling into a coma . The Kanohi Ignika later transformed Dekar into a duplicate of Hydraxon with many of the original ' s memories . Mazeka . A Ko - Matoran who joined the Order so as to put a stop to his Makuta - aligned nemesis , Vultraz . Trinuma . A tall warrior and one of Helryx ' s most trusted aids . Other Members .

He was later killed by the Shadowed One to prevent him from revealing the secret of a number of vials that that the Shadowed One found . Jerbraz : A warrior who was rendered invisible as a result of the Order ' s experiments and carries a sword that was similarly affected ; later recruited the Matoran Mazeka into the organization .
