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.
The Patitites are tiny sentient beings native to the swamps of Patitite Pattuna. Despite their diminutive stature, they pack enough punch to take down a pair of wandering droids. Though technologically primitive, they are bright-minded and do have a grasp on machinery. For example, the Patitites carry powered polearms and were able to assist in repairing a downed Y-wing bomber during the Clone Wars. They are socially primitive, however, living in a tyrannical dictatorship where all Patitites are subservient to their ruler, Hay-Zu. All this changed when R2-D2 and C-3PO inadvertently stumbled upon Patitite society in general, and stumbled upon Hay-Zu quite literally.
