The ruler of the Patitites, the Big Hay-Zu did not let his diminutive size contain his ego or sense of entitlement. Indeed, the portly Patitite was a giant among his kind, ruling with the tiniest iron fist. The Patitites did his every bidding, and should a trespasser wander into Patitite territories, watchful scouts like Jimba and Tagoo would lead a hunting party to subdue the interloper. R2-D2 and C-3PO were trussed up and dragged before the Big Hay-Zu during the Clone Wars, leading to a first contact experience that would flatten the hierarchy of power in Patitite society.

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.

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.
