Biography . In 1 BBY , DT - F16 and her squad were traveling on Freighter 2716 , a covert Imperial ship disguised as a civilian vessel , guarding a large kyber crystal that was being delivered to a rendezvous in the Tonnis sector . Unbeknowest to most of the freighter ' s crew , it was infiltrated by the rebels Saw Gerrera , Ezra Bridger , Sabine Wren and Chopper during a stop at Faos Station . When the rebels discovered the hold with the kyber crystal , she encountered the rebels , and ordered her troopers to open fire . As the trooper s quickly fell to the rebels in the smoke generated by several smoke bomb s tossed by Wren , DT - F16 ordered the remaining troopers to group up . During the skirmish , one of Gerrera ' s blaster shots struck the carbon - frozen crystal , prompting her to order a retreat ; however , she would be the only one to escape , as her remaining troopers were blasted by Gerrera and Wren . DT - F16 later informed the freighter ' s captain , Wells , that rebels led by Gerrera infiltrated the hold and requested reinforcements . The captain gave her reinforcements , warning her that she had to retake the crystal , something which she was aware of as their heads would be gone if the crystal was stolen . When reinforcements arrived ( in the form of four stormtrooper s ) , she returned to the hold , only to find both the rebels and the crystal gone . The captain informed her that they had lost contact with the engine room , so she made her way there . Upon arriving , Gerrera , who had turned the crystal into a ticking time bomb , fled the area after freeing Bridger and Wren . DT - F16 and the stormtroopers prepared to fire , but before they could do so , the crystal electrocuted the two troopers in front of her . She realized that she had to leave immediately and ordered the remaining troopers to abandon ship . She made her way to hold 12 , where a " Lambda " - class shuttle was waiting for her departure . By the time she got there , the freighter ' s prisoner s , who had been freed by the rebels , were boarding . She and the two troopers accompanying her attempted to open fire , but Bridger and Wren , who had also arrived , managed to overpower her and the two troopers before getting on the shuttle and taking off . DT - F16 made a futile attempt to destroy the shuttle with her blaster , and was subsequently killed in the ensuing explosion . Personality and traits .
