Nirach

Nirach is a Toa of Fire

Matoran
As a Matoran, Nirach was a Ta-Matoran mask maker on Spherus Magna. He later quit his job when he was given a Toa Stone from Turaga Hau. He then took it to a temple on the planet and became a Toa.

Toa
After becoming a Toa, Nirach was still a lone wolf, allying with other Toa Teams, Toa, and Matoran. He has saved the land tons of times, and is still trying to do so.
