Zyshak was a Human female bounty hunter during the Old Republic Era. She proclaimed herself to be the most feared bounty hunter in the Rimward sectors. In 3,570 BBY, she was tasked with eliminating a Jedi ambassador on Terminus who was attempting to forge relations between the planet and the Republic. Whilst on the planet she encountered a Trandoshan named Tsek who apparently mistook her for a woman who had saved his life when he was a child. Later, she coerced the whereabouts of the ambassador from smuggler Aseph Cardo and easily dispatched him.
