OOM-90, later known in its rebuilt form as "Pika's Saviour", was a legendary droid hero who initially served for the Trade Federation, and later the Confederacy of Independent Systems during the Clone Wars. When we was built, he was unintentionally put in a circuit that caused him to not be controlled by a Droid Control Ship, due to a shortage in supplies. He was built for use to lead battle droid soldiers at the Battle of Geonosis and various other battles of the Clone Wars. However, around 21 BBY, he was assigned to lead a second battle on the planet. As he led troops to the enemy, the droid and his battilon were struck by a sandstorm during the battle. Unable to move due to the incredible power of the storm, OOM-90 shut himself down permanently along with his other droid comrades.
