X3 (EXE Universe)

X3 was a Force Sensitive Clone trooper. He was a clone, secretly engineered by the Kaminoans from the DNA of Jedi Knight Falon Grey. Although biologically seen a brother of X1 and X2, he was created three years after the creations of X1 and X2 and therefore not mature enough to participate in the Clone Wars from the start. He would however join the Grand Army of the Republic later in the war, serving under Grand Master Yoda.

After Operation Knightfall, X3 went into hiding, unlike his brothers who would enlist in Imperial service. He would meet Aila Dran and her protector former Clone Commander Snowe and eventually meet Starkiller under who he would train further in the Jedi Arts to create a front against the Empire.
