This clone army was the brainchild of X1, a one-time clone trooper who later embraced the dark side as a Sith Lord, with the goal of ruling the galaxy. These clones were manufactured in X1's secret facility on Mustafar, and X1 even kidnapped Luke Skywalker to generate a legion of Dark Jedi clones. Nevertheless, the ambitions of galactic domination were thwarted when X2 spearheaded New Republic troops in a battle that resulted in Skywalker's liberation and X1's demise.
