"We await your orders, commander!"
-OOM-10, to R2-D2
OOM-10 was an B1-Battle Droid reprogrammed by the Galactic Republic to help a Republic Task Force infiltrate a Separatist Prison known as The Citadel to rescue Jedi Master Even Piell and his ship's captain, Wilhuff Tarkin. OOM-10 would be destroyed while serving under Jedi Knight Anakin Skywalker and his astromech droid, R2-D2, when the group was ambushed by Confederate Battle Droids, OOM-10 and two other Reprogrammed Battle Droids were destroyed by an advancing force of BX-series droid commandos and Crab Droids.
Originally a standard B1 battle droid who fought for the Confederacy of Independent Systems before being captured by Republic Clone Troopers alongside two other battle droids and reprogrammed to fight for the Galactic Republic during the Clone Wars.
Mission to the Citadel Edit
OOM-10, alongside the other two Reprogrammed Battle Droids, was assigned to aid a small Republic Task Force to infiltrate the Separatist prison, The Citadel. After landing on the planet where the Citadel was located, this droid stayed behind with R2-D2 and the other two droids. When R2 received orders from Jedi General Anakin Skywalker to pick them up from a certain area of the Citadel, OOM-10, R2 and the other two droids flew the ship to the meeting area.
Sneaking out of the Citadel Edit
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 then realized that Obi-Wan Kenobi and his team would be walking into a trap, he was right as Kenobi and his team were indeed captured but while they were being taken to the interrogation room, OOM-10 managed to convince the security droids escorting them to hand the prisoners over.
Republic affliction revealed and escape attempt Edit
They then rushed Kenobi's team back to the ship waiting outside, where they met with Skywalker's team. However, OOM-10's reprogramming had been revealed to the Separatists by K2-B4 and a group of battle droids, droid commandos with energy shields and two crab droids rushed outside to confront the team. In the firefight which ensued, ARC trooper Echo was killed.
OOM-10 and the remaining members of the team managed to retreat to the caves below the Citadel where they waited for the Republic forces that had been called by Kenobi to arrive. However, while heading for the extraction point, battle droids arrived and ambushed them. R2 then ordered the droids to hold them back while the squad escaped. In the end, although the team managed to escape with only two casualties, the entire battle droid team including OOM-10, was destroyed.
