The Geonosian Juc Fac died long before the Empire. However, a bounty hunter always asked to be called either Juc Fac, or Juc Taa. His true identity remained unknown.
Although he was anonymous, people usually thought he was a crazed droid, because of his metallic voice. But it is possible that he was a cyborg with a droid vocoder. Others think he was possibly a resurrected Juc Fac, although this is highly unlikely.
He wore black armor with blue on the arms, chest, and helmet, strangely the markings had the same placing as the tattoos on the Geonosian. He usually either used a heavy pistol, a Sorosuub "Renegade", or a vibro equivalent of a Geonosian staff. He later acquired a flame thrower attached rifle, used by the Mustafarians. The origin of these guns is unknown, but Bossk was seen wielding one.
He first appeared placing 50000 credits on the escaped members of SARC Squad. He killed all the bounty hunters who tried to escape having the intent on killing SARC Squad. He seemed obsessed with avenging Juc Fac, as one of the escaped clones was the same as the one who killed Juc.
Later, Rebel forces found him in an asteroid field near Rhen Var. He had rebuilt a new Separatist fleet. He escaped with his fleet, but one of his best control ships was destroyed.
Occupation of Mustafar[]
Juc Fac found a surviving droid factory on Mustafar, that housed a few Techno Union officials and the last of Dellso's army. He struck a deal with the Techno Union, and had the Mustafarians build him droids.
Rebellion[]
Some of the Mustafarians grew weary of his disrespect, and turned a group of the droids on him. They were killed, but he was severely wounded. He came out of the med lab with Mustafarian armor, painted the same as his original suit.
