Dashades are tall, humanoid reptiles with dark skin. They are powerful warriors and assassins, and they are not affected by the powers of the Force. Their planet, Urkupp, was destroyed in a supernova caused during the Great Sith War, killing all of the Dashades on the planet.
The most famous Dashade is Ket Maliss, an assassin for the Black Sun organisation who was cryogenically frozen when his boss discovered that only a few Dashades remained. But he is not the last of his species. New Republic historians have found evidence that Dashade mercenaries may have been employed during the great purge of the Jedi that accompanied the rise of the Galactic Empire.
During the Yuuzhan Vong crisis the Dashade people were almost exterminated by the Yuuzhan Vong; but records show that at least one tribe was saved by the Jedi Anakin Solo.
