The Army of Terror was the culmination of Project Starscream. It was a group of biologically created weapons that would never die, could change form at will, could read the minds of its victims and use their deepest fears against them, grew stronger with each feeding and was impervious to the Force—this last ability was never completed. They would follow any order their creator gave them (possibly indicating some form of mental slavery like Stockholm syndrome or a natural inability to form their own decisions). Before they were fully mature, the creatures had the appearance of typical Humans, but would eventually become hideous monsters covered in purple scale-like armor. They grew very rapidly and gained sustenance by absorbing other beings.
