From the Sideshow Collectibles website:
From "Star Wars Episode VI: Return of the Jedi," Sideshow Collectibles is proud to present the R2-Q5 Imperial Astromech Droid Sixth Scale Figure.
As everyone's favorite astromech R2-D2 fought alongside his friends for the Rebel Alliance, his lesser-known Imperial counterpart, R2-Q5, played a critical role in the background as a spy for the Galactic Empire. Specializing in starship diagnostics and repairs, the sleek black-and-bronze R2 unit was charged with maintaining the Death Star's elaborate weapons and security systems, as well as storing the Emperor's plans against the Rebel Alliance. Ready to roll with retractable tripedal treads, hinged panels, and an articulated light-up dome, this delightful droid is perfectly equipped to join the ranks of any Star Wars collection.
