Helryx

Helryx was the first Toa ever created, created as a Toa by the Great Beings at Artahka. She is a Toa of Water, and the leader of the Order of Mata Nui.

Early Life
Helryx was created by the Great Beings. She aided in the construction of Metru Nui and was a member of the Hand of Artakha. When the Hand disbanded, she decided to reform the organization as the Order of Mata Nui, also devising a rule that other Toa could not join the organization as they had destinies of their own.

Helryx watched the awakening of the Toa Mata, first greeting them upon their awakening and informing them of their purpose. She assigned Hydraxon to train the Toa Mata. At this time, she was designing the Swamp Strider, when she was interrupted by Tahu and Kopaka. She revealed to them their destiny, the Codrex, and of Karda Nui.

Order of Mata Nui
At an unknown time, Helryx commissioned Jerbraz, Tobduk, and Johmak, three Order members, to collect carvings and information. She used this information as the Order's atlas of the Bionicle Planet, named BIONICLE World, which was placed in the Order's Daxia library as reference.

Helryx would later be present on Daxia when the Toa Nuva finished the Scroll of Preparations for Mata Nui's Awakening's tasks, in the ninth entry of the Toa Nuva Blog. Once again communicating only by her voice, she thanked the Toa Nuva for their deeds and informed them that the Staff of Artakha, now in the Order's custody, could now be used to undo the effects of the Great Cataclysm.

Weapons and Abilities
Helryx carried a spiked mace and a shield, as mentioned in Dwellers in Darkness. As a Toa of Water, she could create tidal waves and water blasts.
