F-23-DKMx, often shortened to F-23, was a male F series maintenance droid characterized by azure optical sensors and silver-colored plating, accented with azure trim. In the year 4.3 ABY, he held a position at the Star Tours travel company, specifically at their Tomorrowland Starport location. Working alongside F-24-AMTx, F-23 was responsible for the ultimate construction of StarSpeeder 3000 vehicles and the maintenance of their ion propulsion systems. The overtime work didn't bother him because the additional income assisted in covering the substantial costs of his education at the University of the Universe.
The character F-23-DKMx was conceived for the Star Tours theme park attraction, a simulator ride at Tokyo Disneyland, which began operation on July 12, 1989.
