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. She has also been known as the "First Toa" prior to the 2008 storyline.

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.

Order of Mata Nui
Helryx watched the awakening of the Toa Mata on Daxia, greeting them 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.

As the Toa Mata, now transformed into the Toa Nuva, began to complete their destiny by completing the tasks on the Scroll of Preparations for Mata Nui's Awakening, Helryx once again communicated with them after being teleported to Daxia. She told the Toa that they had done well, and told them the Staff of Artakha, now in the Order's custody, could now be used to undo the effects of the Great Cataclysm. She finished by saying they had one last task to complete.

Later, she accompanied Krakua, and Brutaka to Metru Nui. The team rescued an unconscious Takanuva and brought him to the Archives, where she placed a "Kratana" on his face, which gave him visions of the past. This informed him of the Energy Storms that plagued Karda Nui, and that he must travel via Brutaka's Olmak to tell the Toa Nuva of it. As Takanuva left, Helryx informed Brutaka of a mission that would reinstate him in the Order, which was revealed to find Miserix.

Order/Brotherhood War
Helryx later ordered a "Destiny War" against the Brotherhood of Makuta. She dispatched Krakua, and Botar's replacement, to Voya Nui to recruit him. She also sent "Ancient" to confront The Shadowed One, and aid the Order in occupying Xia to prevent the Brotherhood from using their weapons. However, the Dark Hunter leader decided to destroy Xia, therefore, she went with Botar's replacement and a unknown "four-armed giant" to "intimidate" him with a massive tidal wave into following her orders. She also told the Toa Hagah, who were present at Xia, to bring Zaktan and find Makuta Teridax on the Order's behalf.

She returned to Daxia for the duration of the Destiny War. She sent two messengers- one to Metru Nui to send the Toa Mahri to Artidax and use the Heart of the Visorak- and the another to the Pit to release the Barraki so they can fight against the Brotherhood.

Later, during an unknown time, Helryx wrote BIONICLE World for the Order using carvings and information collected by three Order members, Jerbraz, Tobduk, and Johmak.

The Kingdom
In this universe, Matoro hesitated with the Kanohi Ignika and the Great Spirit Mata Nui died. In response, Helryx revealed the Order's existence to assist the migration to Mata Nui, and assist the Toa in barring the Makuta from making it to the island. When Takanuva from the Bionicle universe arrived 100,000 years later, she helped him to talk to the Turaga.

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.
