Being a basic issue of LE repair droid, Leebo worked in Esselesspaceport as a safety standards inspector. At one time, an unknown transport vessel took off while being checked by the droid, making Leebo an unwilling stowaway. From that moment forward, LE-BO2D9 began to work as a ship mechanic, going from one owner to another throughout the coming years. He served multiple masters and each of them updated his abilities and skills, allowing Leebo to do more and more. Finally, he came to the hands of Corellianpilot and mercenary, Dash Rendar. Dash acquired the droid as payment from the Rodian comedian Kood Gareeda, and Dash seemed to believe his new possession acquired his former master's dry sense of humor.
Leebo was present inside the cockpit of the Outrider when Rendar made a last-second escape into hyperspace, avoiding destruction in the maelstrom of debris from the exploded Falleen's Fist.
Leebo often carried a bag with necessary tools with him. Equipped with specialized sensors, holoprojector, single channel long range comlink and computer interface, he was a skilled mechanic and pilot. His programming, being updated by each and every owner, was far more sophisticated than the one installed on stock LE repair droid.
