" Is that all you've got? Does a couple thousand years really wear you down like that?"
-Destros to Makuta Teridax as Maxilos in the Pit
Destros started out as a Dark Hunter, hence the shadowy appearance. But after a year or two of exceeding in the ranks of the Dark Hunters, he realized a greater importance in his life. One day, he traveled to Metru Nui to search for a fugitive that he could collect a bounty on. But what he found was an ancient looking toa being overwhelmed by three Makuta. It was the legendary Toa Helryx pitted against Makuta Antroz, Makuta Vamprah, and Makuta Vantrox. Destros joined in the fight helping Helryx defeat and capture the Makuta. But on the way back to Daxia, Makuta Icarax attacked Helryx and Destros. During the attack, the three captured Makuta escaped and fled the scene. Although he was eager to continue the fight, Icarax fled as well when he had seen he was deserted by his brothers.
Destros followed Toa Helryx back to Daxia where he learned of the Order of Mata Nui. There he was recruited and has since been an invaluable member. He is an elite spy and travels back and forth from Daxia and Destral delivering information on the Brotherhood to The Order. He was captured once on Destral when an ally he had made turned on him. However, Destros killed the guards who captured him and the ally who betrayed him and escaped without any trace left.
Destros was also seen in the Pit fighting Makuta Teridax in the body of Maxilos. Destros defeated Maxilos, but Maxilos escaped before being destroyed.
Very skilled in hand-to-hand combat. He is like a shadow in the night when he is on a job spying, he is silent and unseen.
Appears to be the Kanohi Ignika, Mask of Life. But has never been used by Destros, so it is unknown if it is the true Mask of Life or not.
