Lex began his existence in 75 BBY and, like the others of his line, served on a farm on some forgotten world. There the droid was tasked with shepherding livestock, which he took to with sadistic enthusiasm, often using his fearsome shock-prods to electrocute animals that weren't even misbehaving. When Lex's owner became aware of the droid's aggressive tendencies, he sold the droid to an unknown individual. Shortly afterward, Farmech Industries announced a general recall of the LX units, and the line was disintegrated and forgotten.
