Chewbacca is first mate and copilot of the Millennium Falcon. Chewie, as his friends often call him, is a natural mechanic, essential for the often-temperamental Falcon and its constant need for repairs and upgrades. Two meters tall and over two hundred years old, Chewbacca is extremely loyal to his friend and fellow space traveler Han Solo. The mighty Chewbacca communicates in a series of growls, grunts, and fierce roars, and Han is one of few who understands the Wookiee's native language. A noble sidekick, Chewie often serves as Han's conscience.
