Kun Kolar was the offspring of Darth Matas and Xianna Racor and because of that, hewas a Zabrak/Twi'lek hybrid. He, along with his older brother, were the only ones out of his siblings to look more Zabrak than Twi'lek. He was born without lekku and had more horns than his siblings but he still had Twi'lek features. His skin was blue and he had sharp teeth. Kun was raised as a Sith from birth and because his father was Emperor of the Galactic Empire, he was called Prince Kun Kolar. He reached the rank of Master and earned the title of Darth Sanious. Later he would go to Iridonia and become Kaz'ak of the Zabrak Empire. During his time as Kaz'ack, he was called Kaz'ak Kun, but to the Galactic Empire, he was Prince Sanious.
