In the Star Wars Expanded Universe, Bollux was a humanoid matte-brown bipedal 1.5 meter-tall male-programmed BLX-5 labor droid once produced by Serv-O-Droid, Inc. He held many jobs over the decades, serving many masters, but is best known for his association with Han Solo and Chewbacca during their time in the Corporate Sector and Tion Hegemony. Because of his antiquity, his vocoder is slow, and he almost drawls.
