this Trade Federation battle droid was the Commander of the ground forces sent to control the palace of the city of Theed. The Neimoidians had been controlled by Darth Sidious, and ordered to invade the planet and eliminate any resistance. OOM-9 and its droid troops quickly subjugated the populace of Theed, and eventually captured Queen Amidala and her advisors. During the Battle of Naboo, OOM-9 managed to repel the Gungan Grand Army and began making plans to rout the aliens completely, when Anakin Skywalker managed to destroy the Federation's Droid Control Ship. Without a command signal, OOM-9 was rendered incapable of action, and was among the thousands of battle droids that were dismantled in the wake of the battle. Later, OOM-9's design later became the basis for an entire series of battle droid commanders, in the years following the Battle of Naboo.
