| Group | Order of Mata Nui |
| Mask | Rode |
Axonn was once an arbitrator long before the coming of the Toa, but has since pledged to protect the Kanohi Ignika. He wears heavy armor and carries a Giant Axe with him. Axonn wears the Kanohi Rode, the Mask of Truth, which allows him to see through any trickery. His axe can slice through hard rock and fire energy from its point.
Axonn is a member of the Order of Mata Nui and was once part of The Hand of Artakha. He and Brutaka have resided in the western mountains of Voya Nui and the continent it once was joined to for thousands upon thousands of years. They were the first line of defence for the Kanohi Ignika, protecting the mask and the Matoran who lived on their island. Until the Piraka arrived on Voya Nui, Kazi was the only Matoran who was aware of Axonn's existance.
Axonn was formerly one of the greatest warriors in the BIONICLE universe. After the Hand of Artakha broke up, Axonn had no purpose any more and resorted to conquest. He destroyed whole cities with his axe and his name struck fear into the residents of the far southern lands until the Order of Mata Nui eventually persuaded him to change his causes. Eventually, Axonn became a well-trusted member of the order and was stationed on Voya Nui to guard the Ignika.
