Miserix

"I don't have time for this. I have places to be, and bodies to break. I want you to send out a message to all your friends, to everyone who sails in and out of this island. Tell them Miserix is back, and when I find him, Teridax is dead!"

- Miserix to a trader on Stelt, Destiny War

Miserix is a Makuta and the original leader of the Brotherhood of Makuta until he was overthrown by Teridax. He was imprisoned on Artidax and freed by an Order of Mata Nui strike team, then assisted the Toa Hagah in their search for Teridax.

Ruling the Brotherhood
Miserix was created on one of the Southern Islands by Mata Nui 100,000 years ago. He became the leader of the Makuta's organization, the Brotherhood of Makuta, whose task was to create bio-mechanical Rahi to populate the Matoran Universe.

Five thousand years later, he had learned the Matoran could not afford the trading prices offered by the Vortixx. He approached Chirox and Mutran and had them decide on which one would accompany Icarax and Pridak in this task.

At the time that Pridak left the Brotherhood to start the League of Six Kingdoms, Miserix hired Takadox, one of the leaders of the League, to spy for him. Later, the Makuta attended a meeting with the 6 leaders of the League. The warlords demanded that the Brotherhood continue to make new Rahi and anything else they might need. After the meeting ended, Miserix ordered his lieutenant, Makuta Teridax, to watch the Barraki. Teridax obeyed, later leading the attack that dismantled the League of Six Kingdoms.

500 years later, the Matoran Civil War sparked on Metru Nui. Again, Miserix turned to Teridax and ordered him to stop the war. After the war, Miserix gave Makuta Mutran the mission to visit Tren Krom, believing that such a being of great power could not go unchecked in the universe without knowing its intent or potential danger.

Some time later, Teridax rebelled against Miserix after learning a way to rule the universe with Mata Nui asleep. Miserix was overthrown and Makuta Krika imprisoned him on Artidax. He was reported to have died "in a Rahi creation accident."

Escape from Artidax
Miserix was later freed by Brutaka's team, although not before absorbing Makuta Spiriah into his body. Miserix then destroyed the volcano imprisoning him, grew wings, and fled along with Brutaka's team, heading north to Daxia. He soon left the island to Stelt to spread his message, apparently changing his armor color to green in the process. He caught the Makuta of Stelt and threatened to destroy him if he didn't reveal the location of Teridax. After the Makuta pointed Miserix to the right way, Miserix then absorbed him. Miserix then caught a trader and ordered him to inform everybody that Miserix is looking for Teridax. He then came to Metru Nui and rescued the Toa Hagah and Zaktan from molten Protodermis. Miserix then decided to join them on their mission to destroy Teridax.

After a while, the team then discovered two long-dead bodies within the Core Processor. Miserix concluded that their armor was not made out of Protodermis, and, as a result, they all figured out that the two were not from the Matoran Universe. Suddenly, a portal opened from within the chamber and the team prepared for battle as silhouettes appeared from within. It had turned out to be Helryx, Keetongu, Axonn, and Brutaka who were brought there. Just as the assembled group began to converse about what to do, Teridax revealed himself and destroyed Brutaka's Kanohi Olmak to prevent any escape, then apparently killed Zaktan with a sonic hum that destroyed the globe of water he was in.

Teridax then turned Miserix into a picture. The illusion was so powerful that Miserix thought he was a real painting. He was later freed by Tren Krom, in Lewa's body, and sided with Axonn and Helryx to destroy the Universe, against Brutaka, Tren Krom, and Tuyet, who believed there was another way to stop Teridax without putting the universe in danger. The two sides then battled briefly until Artakha appeared to stop them. However, this caught the attention of Makuta Teridax, and he teleported the entire group into orbit outside the Matoran Universe. The nine beings were then saved by a mysterious figure, whom Miserix identified as Vezon. Vezon introduced to the group to the Fortress's other occupant, a Great Being that had been cursed by the Ignika, imprisoned on Bota Magna, and driven insane. The Great Being pleaded them to release him, resulting in Miserix and his team arguing about whether or not to do so. However, outside the Fortress, the Great Being in disguise, Velika, was planning to destroy everyone, including Miserix, inside. Miserix and the other biomechanical beings managed to escape the fortress. Unbeknownst to them, the cursed Great Being managed to escape as well.

Personality
Miserix could be extremely quick to anger, and ill-tempered. He is extremely intelligent, and very cautious. During his imprisonment, he knew that the other Makuta had shunned their inner light, and proceeded to do so, thinking that he would not allow them to have an advantage over him. His hatred of Teridax is great enough to have him allying with the Toa and Matoran to destroy Teridax.

Mask and Tools
Like other Makuta, Miserix possesses powerful Shadow elemental powers, and the 42 Kraata powers. He is a powerful Makuta that is feared by even other Makuta.

Miserix wielded the Great Mask of Mutation, thus allowing him to cause mutation on any being or creature it is directed at, and that mutation can only be reversed by him. His weapons mainly involved his powerful firestaff as well as his bladed claws and tail. He has a penchant for shapeshifting into fearsome reptilian forms.

Quotes
"Little one, I am Makuta Miserix. I am no one’s pawn. I am no one’s ally. And I am no one’s fool!!"

- Miserix, Federation of Fear

"And what will you use to attack the Great Spirit? Your shadow hand? A troop of Rahkshi? You are an insect in the eyes of Mata Nui-- and in mine."

- Miserix to Teridax, The Mutran Chronicles

"Miserix hates the Brotherhood for turning on him. He would ally with three Matoran and an Ussal crab if it would get him revenge on his fellow Makuta"

- Brutaka to Roodaka on Miserix, "Federation of Fear"

Trivia

 * Miserix's model was created by Sarah Newkirk and was the winner of the Makuta building contest in 2008.
 * For many years, fans attempted to recreate the original Miserix build based off the only picture that existed of it. On January 19, 2020, Sarah Newkirk released the "lost photos" she took of Miserix for the contest on the BIONICLE subreddit. This gave fans a closer look at parts of the MoC, 12 years after the contest took place.
 * Earlier on January 19, a Reddit user named legodetective posted pictures of his recreation of Miserix, which was based solely off the original grainy picture. He described it as "basically impossible to get totally accurate". In an ironic twist, only hours later, Sarah Newkirk posted her old pictures of Miserix - much to the surprise of legodetective and the rest of the community.
 * Miserix and an alternate Teridax are the only Makuta still alive.
