OOL-2 was a B1 battle droid manufactured by Baktoid Combat Automata to serve in the Trade Federation Droid Army. Sometime between 39 and 36 BBY, OOL-2 was deployed to the moon Alaris Prime, which the Trade Federation was trying to colonize illegally. OOL-2 found on Alaris Prime a power core that had been damaged by the moon's gundarks and later completely destroyed by Wookiees from the planet Kashyyyk who were making a legal colonization effort. OOL-2 reported the loss of the power core to the Trade Federation's leader, Nute Gunray, who ordered him to find the gundarks he believed were responsible and kill them. The gundarks were later eradicated from Alaris Prime by the droid army, but the Trade Federation ultimately lost the world to the Wookiees.
