T3

"Treat him well. That's all he asks. You do that and you've got a true Vod in droid form."- Sabine Wren

A3, formerly Imperial Press Corps Astromech 264, is an R4 series astromech droid originally created as a communications and data courier. He first met the Ghost crew when they abducted him so they could give Chopper a similar paint job to his during a mission to find Kanan Jarrus's whereabouts. After being kicked off the Ghost by a jealous Chopper, A3 worked on a farming cooperative before being recovered by the Empire and working at a communications outpost. After a few months on the base he participated in rescuing Sabine Wren from Imperial forces but was unable to rejoin the Ghost crew He was then sent to an Imperial base in the Mandalore sector where he was found by Ezra and Sabine and brought into the Mandalorian Resistance. A3 currently serves as Sabines assistant in her role as Lady of House Wren.

Recovery
"We're getting you out of here. We're gonna patch you up, and we're never gonna abandon you again. You'r going to have a fucking home with us." Ezra Bridger to A3 upon encountering him at the Imperial Supply Depot.

A3 was transferred to an Imperial supply depot in the Mandalore sector following his part in Sabines rescue. Fortunately, his direct involvement was not uncovered and he was not scrapped. However, he was abused and taken for granted by his Imperial supervisors like at his previous posting. He entered a deep depression during this time, a situation not helped by his lack of maintenance. He was in a barely functional capacity when forces of the Mandalorian Resistance attacked the base he was stationed at and he was found by Ezra near the storage area of the facility. A3 was overjoyed to see him but was also afraid he'd be left alone once more. His fear dissipated upon hearing Ezra contact Sabine through his helmet radio and tell her to get a repair kit for an R4 unit. Ezra had to carry him part of the way to the Archangel due to the state of his drive rotors.
