Yellow Fourteen was a Trade Federation B-1 battle droid during the Invasion of Utapau. One of numerous battle droids guarding a number of Utapau Space Fighter Corps pilots after the Battle of Ogana, Yellow Fourteen was approached by Jedi Master Jard Dooku who introduced himself as an ambassador for Supreme Chancellor Finis Valorum. Per the droid's pre-programmed orders, Yellow Fourteen attempted to arrest Dooku, only to be cut down by the Jedi's lightsaber.
