Amethyst

Amethyst is a Dark Toa of Mineral who is the servant of Makuta Improbitas. She works for him as a bounty hunter of some kind, and retrieves artifacts along with Collector. As part of her training, she covered her eyes completely blind, so she can only rely on her instincts. Removing the blindfold in the daylight could possibly damage her eyesight badly.
