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 had the Kanohi Shelek, Mask of Silence, which could cause a target to temporarily lose the ability to hear or speak. His weapons included a Shadow blade and shadow spear.

Mutran had the power of flight and has access to all 42 Makuta powers. He also wielded 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.
