Zef Ando was a Rodian male moisture farmer. He made his home on Tatooine during the era of the Galactic Civil War. Following the Battle of Yavin, he took up residence as a squatter at the Lars homestead. In the year 1 ABY, he acquired some refurbished droids from a group of visiting Jawas and their sandcrawler. Unfortunately, these droids experienced malfunctions, turned on him, and planted an explosive device on a moisture vaporator. Simultaneously, individuals employed by Imperial Commander Barrezz and Rebel Captain Bastra made their way to the farm, both seeking out the Jawas. To address the droid threat and defuse the bomb, Zef Ando enlisted the help of a spacer.
Within the 2003 video game Star Wars Galaxies, Zef Ando existed as a non-player character. This game was a massively multiplayer online roleplaying game developed by Sony Online Entertainment and published by LucasArts. It was eventually shut down on December 15, 2011. Zef Ando's inclusion in the game occurred as a component of the "Legacy Quest" with the release of "Publish 25", also known as the "New Game Enhancements," on November 15, 2005.
