Pyrodax

Pyrodax was a male Makuta, "brother" of Teridax, and enemy of the Neo-Toa Mangai.

Early life
Makuta Pyrodax started life out as all Makuta did. He ruled Metru Nui alongside Teridax, thus making people call them brothers. When Teridax turned evil, Pyrodax was happy to oblige. However, once the Toa Metru defeated Teridax, Pyrodax seemed to vanish, as if he never existed.

Comeback
It wasn’t until Spherus Magna was reformed that he had started to make an appearance again. Reports by Matoran and Agori said that they had seen a black, silhouette-like monster fly by and launch some kind of blast at them. The Neo-Toa Mangai had been dispatched from the Order of the Toa to investigate everything that had happened. They then found Pyrodax, who claimed that he must fulfill Teridax’s unfinished destiny, and take control of Spherus Magna. A battle then struck out, causing Volt and Blaze to be destroyed, Callan to be killed, and Lucem to be wounded. Pyrodax fled the battle, leaving the four Toa in ruin.

Plot to destroy Spherus Magna
Pyrodax had much to do to bring about the downfall of Spherus Magna. From what he knew, he was the last remaining Makuta on Spherus Magna. Luckily for him, at some point, he had found a Kanohi Olmak, a great mask of dimensional gates, and he used that Olmak to go to an alternate universe where the Makuta had taken over the Matoran Universe, and Teridax had killed Mata Nui. Pyrodax approched the alternate universe version of his brother, asking him for at least one Makuta to assist him. Teridax gave him Tundra, a female Makuta of ice, and the alternate universe counterpart of Gorast. Pyrodax and Tundra both returned to the normal universe.

Later, on one of his exploits, Pyrodax encountered a Makuta named Terrax. The two shared a great hatred for the Toa, and so Terrax joined Pyrodax's cause. Together, the three Makuta would form the New brotherhood of the Makuta.

Abilities and traits
Pyrodax was very evil and sinister, a brilliant plotter and thinker, and was a master of shadows. Pyrodax was the leader of the New brotherhood of the Makuta, and led the other two in the group.

Powers and equipment
Pyrodax, being a master of shadow and a Makuta, was able to use his shadow abilities to inflict harm on others. He could channel his shadow powers through his Black fire staff, a black staff with a head in the shape of fire. Pyrodax was also able to conceal himself in the shadows, and be anywhere where shadows were too.

Trivia

 * Pyrodax is the main villain of Commander Spencer's story.
 * "Pyrodax" is a combination of the words "pyro" and "Teridax". This is because his staff's head is in the shape of fire and he is the brother of Teridax.
