Fang Zar was a male human senator who served in the Galactic Senate during the Clone Wars representing Sern Prime. Prior to the war's end, he was part of the Delegation of 2,000 out of concern over various amendments to the constitution. As a result, he and his allies presented the Petition of 2,000 to Supreme Chancellor Sheev Palpatine. Palpatine later transformed the Republic into the Galactic Empire after Order 66 was enacted. One day after the formation of the Empire, Imperial Intelligence conducted a mass arrest of senators, which included Zar.
