R7-A7

R7-A7 was an astromech droid who belonged to Ahsoka Tano. During the Clone Wars, he served in the astromech socket of her various starfighters whenever she flew in combat. R7 remained loyal to Tano after her departure from the Jedi Order, and assisted her alongside astromech droids CH-33P and RG-G1 when she found herself on the run from clone troopers after the issuance of Order 66, including capturing Clone Commander Rex to remove his behavioral modification biochip. R7 was destroyed by blaster fire when Tano and Rex were fighting other clones in the hangar of the crashing Venator-class Star Destroyer Tribunal, but Tano and Rex salvaged his remains from the wreckage. The droid was subsequently rebuilt and ended up in the possession of the Martez sisters, two smugglers and friends of Tano who were working against the Galactic Empire as part of Rex's resistance network.
