Gall Trayvis Gall Trayvis was a male politician who served as a member of the Imperial Senate during the reign of the Galactic Empire . He left the Imperial Senate and posed as a dissident Senator , one critical of the Imperial regime , in order to lure rebellious forces towards destruction . Biography . Gall Trayvis served as a member of the Imperial Senate after the rise of the Galactic Empire . According to rebel fighter Hera Syndulla , Trayvis was the only Imperial Senator who spoke out against the Galactic Empire . In reality , Trayvis remained an Imperial agent and simply posed as a dissident and exiled politician , which allowed him to gain the loyalty of rebel forces and lead them towards their destruction . Five years before the Battle of Yavin , Trayvis sent a message via a hacked HoloNet News transmission stating that Jedi Master Luminara Unduli had survived the Clone Wars and was being imprisoned on Stygeon Prime . The rebels mounted a rescue mission , but found that Unduli was dead and that it was a trap by the Grand Inquisitor . He later broke into Kastle ' s report on the death of Master Unduli telling citizens not to trust the Empire ' s account and to keep her memory alive , though his loyalties meant that the message was a ruse . A short time later , Trayvis sent out another broadcast , this one on the fifteenth anniversary of the rise of the Empire . Trayvis ' message , which was seen in such establishments as Old Jho ' s Pit Stop on Lothal , urged Imperial citizens to boycott celebrations associated with Empire Day as a form of protest against what Trayvis decried as the injustices of the Imperial regime . Given his loyalties , this message was also likely a ruse , possibly to lure out protestors against the Empire and get them arrested . After the events of Empire Day , he broadcasted a message hoping to lure the Lothal rebels to the Lothal City Capitol Building on Lothal . In reality , Agent Kallus of the Imperial Security Bureau and Minister Maketh Tua were orchestrating a covert operation to capture the Lothal rebels . The Lothal rebels managed to find Senator Trayvis in the building , but were quickly ambushed by stormtroopers . While Trayvis tried to convince the rebels to surrender , the rebels managed to escape after Sabine Wren and Garazeb Orrelios dropped smoke bombs from the rafters . Travyis and his rebel would - be rescuers then fled into the old sewers beneath Lothal ' s Capital City . During the escape , Trayvis feigned exhaustion in order to buy time for the stormtrooper pursuers . They eventually split up , and the senator was escorted by Ezra Bridger and Hera Syndulla . When they reached a large fan generator Hera , who suspected Travyis ' treachery , handed him her blaster . Travyis then took the opportunity to show his true colors and attempted to take them captive . Travyis told Hera and Ezra that he was actually helping the Empire to find and hunt down rebels . He also revealed that he had known Ezra ' s parents and claimed responsibility for their deaths , mocking the Bridgers for recklessly throwing their lives away in the name of freedom rather than submission . As he tried to kill them , he discovered that Hera had not charged her blaster , having suspected his true loyalties from his recent actions . Hera then punched him , knocking him out . When Trayvis came to , the rebels had escaped and Kallus looked at him with disgust . Following the failed Imperial operation , Trayvis was interviewed by the HoloNet News anchor Alton Kastle . During the interview , Trayvis confirmed that he had " recommitted " himself to the Empire and claimed that he wanted to make the Empire a better place through peaceful means . He also took the opportunity to denounce that the Lothal rebels , whom he labeled insurgents , for twisting his message into something violent and frightening . At the end of the broadcast , Travyis announced that he was offering a reward for their capture . Travyis ' broadcast prompted the Lothal rebels to hijack the Imperial Communications Center at Jalath in order to broadcast their own message to the people of Lothal . Personality and traits . Gall Trayvis was a human male with fair skin and blue eyes . Five years before the Battle of Yavin , his appearance was that of an older man , with dark but graying hair . He posed as a dissident Senator who despised the Empire and its authoritarian regime , and one who applauded any and all rebellious activity . In reality , however , he was still loyal to the Empire and secretly enjoyed the terrible fates that rebels would suffer due to his actions . When meeting Ezra Bridger , he coldly mocked his parents for their dissidence and cruelly revealed that he had had a hand in their disappearance . He was also a coward , as he had an arrogant and self - assured demeanour when he had the rebels at gunpoint , which dissolved into snivelling weakness when disarmed . Behind the scenes . Gall Trayvis first appeared as a voice over the HoloNet in " Rise of the Old Masters , " the third episode of the first season of the animated television series " Star Wars Rebels " . He was voiced by Brent Spiner who was known for playing Lieutenant Commander Data in Star Trek : The Next Generation . Initially , Trayvis was to be featured in Claudia Gray ' s novel " Leia , Princess of Alderaan " , in which his homeworld would have been revealed as Osk - Trill . However , in the final version of the book , he was replaced by Cinderon Malpe of Derella .
