Fang Zar is an NPC, a Galactic Senator. A friend of Padme Amidala's, he was presumably no longer with the Senate when it grew corrupt with power, and wouldn't have been onboard the Peace Moon when it blew up, wiping out the entire corrupt Senate.
Revelation of the Sith Edit
C-3PO and R2-D2 attended a meeting Padme was having with her fellow Senators. Padme suggested they overthrow the Senate, but her fellow Senators were all weak-willed and timid except for Bail Organa. Fang Zar was present but didn't say anything.
Padme and a group of Senators, including Jar Jar Binks, Fang Zar, and a Mon Calamari Senator confronted Palpatine and Anakin. Padme told Palpatine that she and her fellow Senators were going to overthrow the Senate, much to the other Senators' surprise. Fang Zar objected to this, asking how they'd be able to maintain control without the bureaucracy. Palpatine suggested that would be unwise. Senator Jar Jar Binks said he agreed with Palpatine.
