Ko Zatec-Cha was a magic user and royal vizier of the planet Tammuz-an. Unsatisfied with his station, he sought to become absolute ruler of the planet and went to extremes to subvert the authority of the ruling monarch, Prince Mon Julpa.
Zatec-Cha as ruler of Tammuz-an
Several years before the Galactic Civil War, Ko Zatec-Cha embarked upon a scheme to do away with Prince Mon Julpa for good. He used his magic to transform the prince into an addle-brained amnesiac. Dressing him up as a broken-down android, he exiled him from Tammuz-an, forcing him to wander the galaxy as a simple-minded drifter. One of Mon Julpa's loyal followers, Sollag Den, stole the Tammuz-an royal scepter and fled his homeworld in the hopes of one day returning it to the prince. This greatly angered Zatec-Cha, for without the scepter, he could not legally assume the power of the throne. Zatec-Cha hired a bounty hunter named IG-88 and instructed him to recover Mon Julpa and the scepter.
Later, Mon Julpa found himself at the auction block in a mining colony on Tyne's Horky. There, he met the miner Jann Tosh and the droids C-3PO and R2-D2. Together they helped reunite Mon Julpa with Sollag. Sollag used the magic of the royal scepter to disperse Zatec-Cha's magic, giving the prince command of his faculties once again. Joining with a freighter pilot named Jessica Meade, they returned to Tammuz-an to retake the throne.
IG-88 eventually tracked them back to the royal city and acquired the royal scepter. With it, he captured Mon Julpa and brought him before Zatec-Cha, who had captured Jessica and Sollag. Zatec-Cha cast the prince into a dungeon pit in the hopes that he would be consumed by a monstrous Durkii. The only thing left to do was to assume the mantle of King of Tammuz-an.
In order to properly obtain the title, Zatec-Cha had to present the royal scepter to the Keeper of the Tower and place it inside a special housing at the first sun of the equinox. However, Mon Julpa escaped from the Durkii pit with the help of his friends, and after a chase, intercepted Zatec-Cha at the tower. After a brief struggle between Mon Julpa, Zatec-Cha and their respective allies, the former took the scepter from the latter and placed it inside of the tower, securing his rightful position as king. Zatec-Cha was then imprisoned for his treason, his chances of becoming king forever lost.
Zatec-Cha was a male member of the Tammuz-an species with purple skin, a long black mustache, and a goatee. He had two triangular markings below each eye. Zatec-Cha was always seen wearing the prestigious regal garments of his station.
Zatec-Cha was assisted by an incompetent Tammuz-anian sycophant named Vinga. Vinga's primary function was to speak Zatec-Cha's praises and execute every perfunctory job duty that Zatec-Cha handed down to him.
