"Hold it. Where are you going with these prisoners?''" "We're transferring them aboard the shuttle from Citadel to Point Tarron." "Point Tarron? There's no outpost there." "''Uh, it's new...we have orders. We're coming aboard."

- OOM-10 tries convincing a B1 battle droid into letting them leave the Citadel.

Originally built as a CIS battle droid, it was captured and reprogrammed to listen to R2's orders. It, along with two other reprogrammed battle droids helped sneak the Jedi aboard the Citadel in order to rescue Jedi Master Even Piell. This droid stayed behind with R2 and the other two droids on Lola Sayu, the planet housing the Citadel. When R2 received orders from Anakin to pick them up from a certain area of the Citadel, OOM-10, R2 and the other two droids flew the hip to the meeting area but when K2-B4, the tactical droid stationed in the Citadel arrived instead of the team, OOM-10 and the droids were forced to act as if R2 was their prisoner and were taking him for interrogation. When they were in the clear, R2 surmised that Kenobi and his team would be walking into a trap. He was right as Kenobi and his team were captured. While they were being taken to the interrogation room, OOM-10 managed to convince the security droids escorting them to hand the prisoners over to them. They then rushed back to the ship outside where they had met with Skywalker's team. However, OOM-10's reprogramming had been revealed to the CIS and a group of battle droids, droid commandos with energy shields and two crab droids rushed outside to confront the team. In the firefight, ARC trooper Echo and one of the reprogrammed battle droids were lost. OOM-10 and the remaining members of the team managed to retreat to the lower caves of the planet below the Citadel where they lay in wait for the Republic that had been called by Kenobi, to rescue them. However, while heading for the extraction point, battle droids arrived and ambushed. R2 ordered the droids to hold them back while the team escapes. Although the team managed to escape with with only two casualties, the entire battle droid team, including OOM-10 were destroyed.
