Have you ever come across a fog bank that came out of nowhere, if so then you're lucky. Most that enter the fog don't come back, and those that have tell terrible tales, tales of hounds stalking them, and a shadowy figure coming towards them. When he was a member of the Brotherhood of Makuta, Tyronyx was greatly feared, even by his fellow members. He was one of the first to join the Makuta's plot to overthrow Mata-Nui, and while he was on the outside a supporter of Makuta's, he was secretly a spy for the Order of Mata-Nui, responsible for giving the Order the information required to send Takanuva to Karda-nui in time to warn the Toa Nuva. He is often seen with a Slavak hound.
As keeper of the staff of the universe Makuta Tyronyx makes a formidable opponent with the ability to use every element (thankfully not at the same time). He later helped track down Toa Bucara.
