The Zarbi Supremo was the intelligent leader of the Zarbi.
Biography
The Zarbi Supremo was three times the size of the average Zarbi at approximately 20 feet tall. He dreamed of conquest, both on a planetary and universal scale, and had fitted the planet Vortis with massive engines that brought it to the vicinity of Jupiter, within striking distance of his first goal, Earth.
The Zarbi Supremo was defeated when the Doctor arrived on Vortis and, with the help of Gordon Hamilton, freed the crew of the Solar Queen who then killed the Zarbi Supremo, thus returning control of the planet to the peaceful Menoptera. (DWA: The Lair of Zarbi Supremo)
