Ra-Zyrth was a male Massassi who served the Sith Empire during the time of the Great Hyperspace War. He became one of the top commanders of Naga Sadow, the leader of the Sith Empire, and Sadow used dark side alchemy to transform Ra-Zyrth into a mutated monstrosity. The Massassi subsequently entered a deep sleep inside a suspended animation capsule, which was fired onto the planet Coruscant during a Sith attack on the world in 5000 BBY.
