F-22, whose full designation was F-22-RGKx, was a male F series repair droid equipped with green photoreceptors, a silver plated body, and gold accents. Around the year 4.3 ABY, this droid worked for the Star Tours travel company, providing upkeep to the hangar fans located in Tomorrowland Starport. F-22 was known for his grumpy disposition, frequently voicing grievances about numerous subjects, including his former manufacturing plant, the present state of "kid" droids, and even his "mother-in-law". At the conclusion of his day's work, F-22 frequently visited the Alien Quarter Cantina. He also found pleasure in the music of The Rolling Droids and the beverage oil on the rocks.
The character F-22-RGKx was conceived for the Star Tours simulator ride theme park attraction at Tokyo Disneyland, which began operation on July 12, 1989.
