224 was an OOM command battle droid who served in the Separatist Droid Army during the Clone Wars. Shortly after being promoted, he was deployed to the moon Rugosa under the command of Sith apprentice Asajj Ventress where he led Separatist forces in an attempt to stop Jedi Grand Master Yoda from meeting with King Katuunko of the Toydarian species. After numerous attempts to kill Yoda failed, the Jedi eventually came out of hiding and sat calmly in front of 224's Armored Assault Tank. The droids were unsuccessful in anticipating the Jedi's ruse however, and after Ventress ordered 224 to open fire, he was quickly destroyed by Yoda.
