C-3PO is a droid programmed for etiquette and protocol, built by the heroic Jedi Anakin Skywalker, and a constant companion to astromech R2-D2. Over the years, he was involved in some of the galaxy’s most defining moments and thrilling battles -- and is fluent in more than seven million forms of communication. In the years after the Empire's defeat, C-3PO acquired a red-plated arm, keeping the mismatched limb to honor a fellow droid's sacrifice.
A resourceful astromech droid, R2-D2 served Padmé Amidala, Anakin Skywalker and Luke Skywalker in turn, showing great bravery in rescuing his masters and their friends from many perils. A skilled starship mechanic and fighter pilot's assistant, he formed an unlikely but enduring friendship with the fussy protocol droid C-3PO.
Chopper was the resident droid of the Ghost, assisting the crew in everything from ship maintenance to combat -- even though he didn't always want to. After many years of repairs and patch jobs, Chopper had a beat-up, worn look that matched his sometimes cranky personality. Aesthetics aside, he was an essential part of this small rebel team, and ultimately, was loyal and heroic.
