Miserix

"Swords so easily drawn beg to be used... and are rarely so easy to put away again. These Barraki may prove troublesome. Watch them."

- Miserix to Makuta Teridax, after a meeting with the Barraki

Miserix was created alongside most other Makuta, and was appointed to run the Brotherhood by Mata Nui shortly afterwards.

Around the completion of the island of Destral, Miserix ordered Mutran, Icarax and his aide, Pridak, to travel to Xia and negotiate with the Vortixx about lowering their prices for trade with the Matoran.

When Pridak left the Brotherhood and started the League of Six Kingdoms, Miserix hired Takadox to act as a spy for him. He later attended a meeting with the Barraki, where they demanded that the Brotherhood continue to provide Rahi and anything else they might ask for. Miserix then ordered his most trusted lieutenant, Teridax, the future Makuta of Metru Nui, to keep watch on the Barraki. This Teridax did and he eventually led the attack which effectively ended the League's reign.

500 years after the defeat of the League of Six Kingdoms, the Matoran Civil War broke out on Metru Nui. Once again, Miserix turned to Teridax for assistance in this matter and ordered him to stop the fighting, an order which the lieutenant brutally carried out by means of what was later referred to as the Archives Massacre. During the War, Miserix sent Mutran on a mission far to the south to pay a visit to Tren Krom, as the Brotherhood could not allow a being of such great power to go unchecked in the universe without knowing its intent or potential danger.

Following the ordeal, Miserix decided that each Makuta would be assigned a particular region to supervise to avoid any similar conflicts in the future. Because of his trust in Teridax, Miserix assigned "the prize" of Metru Nui to his lieutenant. Miserix himself chose to remain on Destral and run the Brotherhood from there, not taking any particular region to watch over.

When Mutran returned with the knowledge of how the universe worked he had gleaned from Tren Krom, Teridax demanded Convocation on Destral, something no Makuta other than Miserix had ever done. To exacerbate the situation, he had not asked Miserix's permission to do so. In the Convocation Chamber of the Makuta Fortress, Teridax revealed his plan to the assembled Makuta. Miserix correctly understood this move to be a bid to take over leadership of the Brotherhood and fired Shadow energy from his gauntlet, blasting Teridax halfway through the wall. Miserix dismissed the plan as treason and stupidity, but Teridax's retaliation was fierce and swift, knocking his leader against the walls of the Chamber and then pinning him to the ground with his staff pointed at Miserix's throat. Miserix seized the staff and channeled his Lightning power through it, sending Teridax hurtling backwards. Teridax then seceded from the duel and asked his fellow Makuta to choose whom they wished to follow. Miserix was initially joined by some loyal Makuta, but after seeing that most had sided with Teridax, they reluctantly abandoned their leader as well. Teridax claimed leadership of the Brotherhood through the will of the Convocation and as his first act, sentenced Miserix to death.

He then ordered Krika and Spiriah to carry out the execution, but, unbeknownst to Teridax, Krika instead imprisoned Miserix on the island Artidax, far to the south of the Matoran Universe. There, he is heavily guarded by Rahi and other beings strong enough to detain a Makuta. Tahu and Kopaka unknowingly saved Miserix by closing the volcanoes there, which would have killed Miserix. The Order of Mata Nui member Brutaka led a team of villains to Artidax to recue him, though what happened after that is unknown.
