The advanced Tau Warriors have been bred for the searing Vulcatraz temperatures. Most are male, with the female of the hive being the Red Queen. The caste-based Tau are attempting to repulse the Cyberbrains, which occasionally leads them to volcanoes on Earth. Their starships, Tau Destroyers with a Cyberpower of 389, carry this war-like species, armed with Fire Daggers. The rogue Tau known as Vulcan is the fifth most-wanted alien due to his fiery breath.
