Mutran

Mutran was a Makuta and a member of the Brotherhood of Makuta. He specialized in mutations, along with Chirox. In Chirox's opinion, Mutran's Rahi never had enough teeth, nor were they intelligent enough.

Weapons and Abilities
Mutran wears the Kanohi Shelek, Mask of Silence, which could cause a target to temporarily lose the ability to hear or speak. His weapons include a Shadow blade and shadow spear.

Mutran has the power of flight and has access to all 42 Makuta powers. He also wields shadow energies. Mutran was amongst the Makuta to invade Karda Nui. Unlike the other Makuta there, Mutran was not blinded by the light that caused the revival of Mata Nui because he was not nearby when the event occurred.

Mutran is responsible for the bat-like appearance of the Shadow Matoran, as well as giving Radiak four legs one day when he was moody. He and the Shadow Matoran Vican, who acts as his lab assistant, are the guards to the Shadow Leech vats located deep in the heart of a hive. He and Chirox are the creators of the Shadow Leeches and the Tridax Pods.

History
Sometime long before the Great Cataclysm, Mutran was sent on a diplomatic mission to Xia. When he left, he accidentally left behind his Sentient Rock, which he had brought with him. When he realized he had forgotten it, he figured it wouldn't be a problem and so didn't go back for it. The rock eventually started eating Vortixx and grew into the famous Sentient Mountain.

Later, after the defeat of the League of Six Kingdoms, Mutran and another Makuta, Gorast, were sent to one of Kalmah's fortresses for clean-up duty. While there, Mutran discovered a carving telling how Kalmah had noticed something odd about some of Mutran's rahi, the Blade Burrowers. It appeared that the tunnels they dug were not random, but in fact were all of the same pattern, a map. Mutran had no idea what the Burrowers were mapping or why, and was disturbed by it.

While the Matoran war in Metru Nui was going on, Mutran was sent on an unknown mission to meet with a legendary entity called Tren Krom.
