Axonn was a member of the Hand of Artakha before it disbanded and was replaced by the Order of Mata Nui. Axonn was given the offer to join the Order by Hydraxon, and accepted. Eventually, Axonn was tasked with protecting the Mask of Life near the Village of Voya Nui, along with his friend, Brutaka. He was placed on this assignment before the Order's Divisions were formed, and therefore isn't an official member of any division.

After the Great Cataclysm, Axonn noticed Brutaka's loyalty to Mata Nui had been shaken, having believed the Great Spirit betrayed them. Axonn held firm in his belief that the Great Spirit had been cast into a slumber, and that he would one day reawaken to restore order to the universe.

1,000 years later, the Piraka, Toa Nuva, and Toa Inika arrived on the Island of Voya Nui, seeking the Mask of Life. Axonn worked to assist the Toa against the Piraka, however Brutaka betrayed him, now convinced that serving Mata Nui was a lost cause.

Axonn and Brutaka fought, and Axonn was eventually able to defeat him. He summoned Botar to take Brutaka to the Pit, but vowed to one day rescue his friend.

Axonn went on to assist the Toa Mahri in recovering the Mask of Life and rescuing the Matoran of Mahri Nui. After the Mahri restored the Southern Continent from the effects of the Great Cataclysm, Axonn was summoned by Krakua to assist in the Order's upcoming war against the Brotherhood of Makuta.

Axonn returned to Daxia, where he reunited with Brutaka, who had since restored his faith in Mata Nui. The two went on to recruit the Skakdi of Zakaz to the Order's side of the war. They then went on to locate the site of the Makuta's creation, a pool of Antidermis hidden on one of the Southern Islands. Axonn and Brutaka fell into the pool, but Brutaka was able to absorb a large amount of the essence, increasing his strength. Brutaka recued Axonn from the pool, and teleported them both to the Core Processor.

Once inside the Core Processor, they discovered Helryx, Makuta Miserix, Keetongu, and the Toa Hagah. Brutaka revealed they were within the mind of Mata Nui, and Makuta Teridax revealed he was already inside.

Teridax teleported Axonn and Brutaka out of the Core Processor, but they made their way back. When they arrived again, they found Helryx, Miserix, Tren Krom (In Lewa's Body), Tuyet, Hafu, and Kapura. The group split up into separate sides, and began to fight over whether or not to destroy the Core Processor, until Artakha arrived to break up the fighting. Teridax then teleported all the beings into space.

The group was rescued from space by Vezon, and they found themselves in an abandoned fortress on the moon of Bota Magna. There they discovered Tomidas, an imprisoned Great Being who was cursed by the Mask of Life, and debated whether to free him. Lewa, Hafu and Kapura left the fortress.

While in the fortress, Mata Nui managed to defeat Teridax and reunite Spherus Magna, transforming the moon of Bota Magna into the forest of Bota Magna. Unbeknownst to the beings within the fortress, another Great Being, Velika, was rigging the fortress to explode, intending to wipe out many of the most powerful beings from the Matoran Universe.

Velika's explosives went off, killing Axonn, and Brutaka. Tomidas survived, but remained imprisoned, and Helryx was rescued by Artakha, who revealed himself to be a Great Being in disguise. Miserix, Tuyet, and Vezon's fates are currently unknown.
