OOM-10 had many blue markings throughout its body, indicating his status as an OOM Pilot Droid. OOM-10 had skills in piloting shuttles as well as tactical fighting skills and was equipped for combat on land.
During 21 BBY, OOM-10, along with 2 reprogrammed Pilot Droids helped several Jedi and clone troopers, all of who had been carbon frozen, sneak into the planet of Lola Sayu. When the shuttle made it near the planet, K2-B4 scanned it for life signs, failing to find the strike team frozen inside. After landing the ship and unfreezing the group, OOM-10 stayed with the ship alongside his commander.
OOM-10 was later ordered by Obi-Wan Kenobi and Anakin Skywalker to rendezvous with them at the landing zone. Expecting them to be on time, OOM-10 and his company were greeted by K2-B4 instead. In an attempt to deceive the Tactical Droid, he used R2-D2 to act as a hostage. Unaware that the scheme was a failure, K2-B4 gained control of the shuttle.
