Shortly after Mata Nui's departure from Spherus Magna, he created the Makuta species to manage the Matoran Universe and populate it with Rahi. The Makuta formed the Brotherhood of Makuta, with Makuta Miserix as their leader.

Later, the League of Six kingdoms attempted to overthrow Mata Nui and conquer the Matoran Universe. However, the Brotherhood of Makuta prevented this. Inspired by the League, Makuta Teridax formulated a plan to overthrow Mata Nui himself.

Following the Matoran Civil war in Metru Nui, Miserix appointed several Makuta to govern the islands in the Matoran Universe. While assigning positions to the Makuta, Dragonax was placed in charge of managing Brotherhood prisoners.

Teridax presented his plan to the Brotherhood, and the majority of the Makuta were in favor. Miserix opposed the plan, as well as five other Makuta. Teridax then led a mutiny, and placed himself in charge of the Brotherhood. He ordered the six Makuta killed, but unbeknownst to him, Miserix was not killed, but imprisoned, and the other five Makuta went into hiding.

For his own well-being, Dragonax did not oppose Teridax, but remained secretly loyal to Miserix.

Eventually, the Makuta evolved into forms of pure energy, and the Brotherhood commissioned the Nynrah Ghosts to rebuild their armor to accommodate their new, gaseous forms. Teridax realized the Makutas' new forms would be especially vulnerable to the elements of Iron and Magnetism, so he organized raids on known Fe-Matoran and Fa-Matoran settlements, in order to exterminate many possible future threats.

Later, Teridax caused the Great Cataclysm, which put the Great Spirit Mata Nui into a deep sleep. Dragonax continued to follow orders from the Brotherhood, despite the organization officially becoming the enemy of the Matoran.

When the Order of Mata Nui came out of secrecy, they declared war on the Brotherhood. During the following Order raid on Destral, Dragonax escaped with several Brotherhood prisoners in an airship, and was last seen heading toward the Southern Islands.
