This Reprogramed Battle Droid was an B1-Battle Droid that served under R2-D2 in his Battle Droid squadron as an Republic Battle Droid. He fought with the Republic during the Battle of Lola Sayu, but was destroyed when the droid squad was ordered to defend the Republic troops from advancing Confederate droid forces while the clones escaped. They did as ordered and OOM-8 bid farewell to his commander, R2-D2, before being gunned down by an Crab Droid. His fellow Battle Droid teammates would also be gunned down with two clone troopers.
