RK-242 was an Imperial stormtrooper who was stationed on Jakku shortly before the Battle of Jakku. He was among the Imperial remnants forces that had relocated to the barren desert world under the orders of Counselor Gallius Rax. The harsh conditions affected RK-242 and he voiced the opinion that he did not want to be on Jakku anymore. As punishment, he was beaten up by Sergeant Rylon and his fellow stormtroopers. The altercation was intercepted on radio by Grand Admiral Rae Sloane and the former rebel operative Brentin Lore Wexley. The two found a battered and brutalized RK-242 and comforted him. Sloane reassured him that she had come to restore order and told him not to tell anyone of their meeting. While he was putting on his helmet, Sloane shot him dead to conceal their presence. When Brenting objected, Sloane countered that they could not help him.
