The Thraddash are a race of intellectually challenged barbarians from the Draconis stars. They have built and decimated their civilization nineteen times by the time of Star Control II/The Ur-Quan Masters, naming their new civilizations numerically, i.e. Culture 19. They are best dealt with by tricking them into attacking the Kohr-ah, waiting for them to retreat to their space in diminished numbers, then pummeling them mercilessly into submission, where they will rename their civilization Culture 20 or a title of your choosing. Their alliance will make the aquisition of the Aqua Helix, an important artifact needed to repair the Ultron and ultimately beat the game.
