Mart Mattin lived on the planet Mykapo during the Age of the Empire with his father and mother . His father was the leader of a rebel cell called the Iron Squadron , which consisted of the Theelin Gooti Terez , the human Jonner Jin , and the astromech droid R3 - A3 . These rebels operated from a YT - 2400 light freighter called " Sato ' s Hammer " . At some point , Mart ' s father was killed during a clash with Imperial forces . Mart took over leadership of the Iron Squadron and did not maintain contact with his uncle Jun Sato , the commander of the Phoenix Cell . Mart and his fellow Iron Squadron members regarded Mykapo as their home and harassed Imperial forces there . Joining the rebellion . In 2 BBY , the Empire decided to impose martial law on Mykapo . They dispatched an advance patrol , consisting of a " Gozanti " - class cruiser and several TIE fighters to lock down the system . Mart ' s Iron Squadron clashed with the Imperial patrol and sustained damage to their ship ' s hyperdrive . Shortly later , Hera Syndulla and her Spectres along with Phoenix Squadron arrived to evacuate rebel sympathizers on Mykapo . They came to the aid of Iron Squadron by attacking the Imperial fighters . Hera contacted the Iron Squadron and told them that they needed to evacuate the system . Mart thanked the rebels for their help but declined their offer of assistance . When Hera reiterated her warning , Mart replied that the Iron Squadron did not run . He then flew the " Sato ' s Hammer " towards the " Gozanti " cruiser and dropped several explosive cargo pieces which destroyed the Imperial ship . Following the skirmish , Mart chatted with Hera via the intercom and invited her and her crew aboard the " Sato ' s Hammer " . Hera ' s ship " Ghost " docked with the " Sato ' s Hammer " and Mart ' s crew entertained Hera and her rebel comrades Ezra Bridger , Sabine Wren , and the astromech droid Chopper . Mart met with the Spectres in his ship ' s cockpit and acknowledged that he was Commander Sato ' s nephew . When Mart asked Hera if his uncle had sent him , Hera replied that she and her fellow rebels had come to evacuate rebel dissidents from Mykapo . Mart rejected any idea of evacuating Mykapo as cowardice and remarked that he could hold off the Empire . When Hera warned them that the Empire would return , Mart responded that he and his crew had just destroyed a Star Destroyer ; mistaking the " Gozanti " cruiser for one . In the end , Mart and his crew decline Hera ' s offer to leave and reiterated that they would defend Mykapo from the Empire . Despite the unsuccessful meeting , Ezra persuaded Hera to let him , Sabine , and Chopper stay behind to repair the Iron Squadron ' s hyperdrive . Ezra was still determined to win over the squadron . Hera reluctantly sanctioned his mission but warned the rebels that they needed to leave at the first sign of Imperial activity . Mart and his crew allowed Sabine and Chopper to assist R3 - A3 with the repairs . However , he still thought that it was a waste of time . Sabine and the droids managed to repair the hyperdrive . However , their efforts came to naught because Mart redirected the power to the armaments and deflector shield s . Upon sighting Imperial reinforcements , Mart ordered his crew to their battle stations . This second Imperial force was commanded by Admiral Kassius Konstantine and consisted of an " Arquitens " - class command cruiser and two more " Gozanti " cruisers . Despite the odds stacked against the Iron Squadron , Mart refused to back down and flew the " Sato ' s Hammer " towards Konstantine ' s forces . Ezra and Sabine disagreed and managed to convince Gooti , Jonner , and R3 - A3 to accompany them into their shuttle , " Phantom II " . When the ship ' s power broke down , Mart saw reason and accompanied the rebels aboard the " Phantom II " . Once everyone else had gone aboard , Mart stayed behind and disengaged the airlock . Changing his mind , Mart launched a frontal attack on Konstantine ' s light cruiser . However , the Admiral neutralized his explosives by unleashing his frontal batteries . Mart attempted to flee but the " Sato ' s Hammer " engines were knocked out by TIE fighters . Trapped , Mart then told the Spectres and his crew to flee without him . Instead of blasting Mart and his ship , Admiral Konstantine ordered one of his TIE bombers to plant a magno - mine on his ship ' s hull . Panicking , Mart sent a distress signal to Hera and her crew . Konstantine allowed him to transmit the signal before shutting it off . While Mart reflected on his mistakes , Hera , her crew , and the rest of Iron Squadron decided to rescue him . Mart was relieved when Hera ' s ship " Ghost " exited hyperspace . He then informed Hera that the Imperials had attacked a magno - mine to his ship . Mart watched as Hera led Konstantine ' s TIE fighters on a pursuit . This distraction enable Chopper and R3 - A3 to deactivate the magnonmine and its detonator . They then reattached the mine to one of Mart ' s cargo boxes . Following a brief dogfight , Hera managed to attach the " Ghost " to the hull of " Sato ' s Hammer " . Shortly later , Mart ' s uncle Commander Sato arrived on a CR90 corvette and attacked Konstantine ' s cruiser . Sato reassured his nephew over the com that he was here to get him out . Hera then told Mart to get the bomb ready since she was making a run for Konstantine ' s cruiser . The rebels flew over the light cruiser and Mart dropped his explosive cargo . The magno - mine damaged the forward section of Konstantine ' s cruiser and set the ship ablaze . The rebels escaped the system just as Grand Admiral Thrawn arrived on his Star Destroyer " Chimaera " . Upon seeing the Star Destroyer , Mart and his crew realized that it was difficult for them to take on the Empire by themselves . Hera flew Mart and his ship to Chopper Base on the planet Atollon . There , Mart embraced his uncle Sato , who thanked Hera and her crew for saving his nephew . Mart then embraced his crew in the presence of the Spectres and Commander Sato . Following the recent events , Mart and his crew decided to join the rebellion . Assault on Lothal . Mart took part on the Rebel assault on Lothal . However , the attack failed as Thrawn had anticipated that they would have broken through the outer blockade , and had a large group of TIE fighters intercept the strike force . Mart crash - landed in Capital City , managing to survive . However , three Imperial stormtroopers had surrounded him , and his droid , R3 - A3 , attempted to fend them off , before being disintegrated by them . Hera and Chopper , who also survived their crash - landing , saved him by hijacking the nearby troop transport and ramming them into the troopers . Mart allowed Hera to take off R3 ' s transmittor , stating that the droid would have helped in any way possible . Soon after this , they were ambushed by the assassin Rukh , who was tasked with capturing rebel pilots . They managed to drive him away temporarily , and upon finding a sewer entrance , was told by Hera to create a distraction . Mart distracted the two stormtroopers , shooting at one , prompting the other stormtrooper and the AT - DP to chase him . Mart overpowered the other stormtrooper while Hera immobilized the AT - DP . Rukh made his move again , successfully separating Hera from Mart and Chopper . Mart was concerned with Hera ' s safety , who told him to escape before the Imperials could apprehend him . He followed the starbird s and was eventually rescued by Kanan Jarrus , apologizing to him for not being able to protect Hera . Kanan ' s death . Mart , Ryder Azadi , and Jai Kell watched while the Spectres Ezra , Sabine , Zeb , and Chopper built three Loth - bat glider s for their mission to rescue Hera Syndulla . Though the rebels managed to rescue Sabine , Kanan was killed when Governor Arihnda Pryce bombarded the Lothal City fuel depot . Following Kanan ' s death , Mart along with Jai Kell and Azadi listened to a propaganda broadcast by the Imperial broadcaster Alton Kastle claiming that the rebellion on Lothal was a lost cause . However , the Spectres later learnt that Kanan ' s sacrifice was not in vain and that the explosion had knocked out the production of TIE Defenders on Lothal . Personality and traits .
