RS-2112 was a stormtrooper of the human species who fought for the First Order as part of the 709th Legion. In the year 34 ABY, RS-2112 was among the stormtroopers sent to Batuu, a planet situated in the Outer Rim. Dressed in typical First Order stormtrooper armor, the trooper went with a stormtrooper sergeant to face the criminal Kendoh Voss along with her gang inside of Dok-Ondar's Den of Antiquities. Because Dok-Ondar, the owner of the antiquity store, and Voss did not heed the sergeant's threats, the sergeant instructed RS-2112 to use intimidation on the criminal. The stormtrooper gladly followed the order, using a Z6 riot control baton to strike Wooro, an associate of Voss.
RS-2112 made an appearance in the Star Wars: Galaxy's Edge comic-book series' fifth issue. Marvel Comics published this issue on August 28, 2019, and it was written by Ethan Sacks and had illustrations by Will Sliney.
