The Matoran in Hundraz's homeland performed multiple experiments to create more powerful weapons, but instead, they created a substance that releases radiation and mutates everything within the radiation range into the forms that reflects their thoughts. Hundraz was infected during this sequence of events and was thus turned into a three-eyed monster. His speed increased and his ambition, as a reflection, turned into shadow energy that he could now channel through his third eye. His organic parts had almost disappeared during the transformation, he became much stronger as well as had become more intellegent. Altogether his senses were left extremely accurate.
