Chewbacca, a Wookie, became Han Solo's first mate and companion after Solo, then an Imperial Captain, refused an order to kill him while Chewbacca was a slave of the Empire. Solo was dismissed from the Imperial Navy for disobedience and became a smuggler. Chewbacca owed a life debt to Han and would serve Han Solo for the rest of his life. Serving as co-pilot and partner to the wily smuggler on board the Millenium Falcon, "Chewie" has made his mark on the Star Wars universe and with fans everywhere. Chewbacca was named one of the "greatest sidekicks" in film history by Entertainment Weekly.
