U-3PO/Legends

U-3PO, also known as Yoo-Threepio, was a 3PO-series protocol droid created by Cybot Galactica prior to the Battle of Yavin. U-3PO served in the Diplomatic Corps of the Royal House of Alderaan during the Galactic Civil War.

During the time of the Galactic Empire, U-3PO was reprogrammed by Imperial agents to serve the New Order as an espionage droid, making the droid an unwitting spy for the Empire. U-3PO was aboard Tantive IV when it was attacked by the Star Destroyer Devastator and boarded by Darth Vader and the 501st Legion.
