The JR-4 Recon Droid represented a particular type of recon droid that saw usage throughout the Third Galactic War, a conflict pitting the Galactic Republic against the Sith Empire.
The initial appearance of the JR-4 Recon Droid occurred within Star Wars: The Old Republic's Legacy of the Sith expansion, functioning as a pet. This droid, drawing inspiration from BD-1, was offered as a miniature pet to commemorate the launch of Star Wars Jedi: Survivor. It was granted to players who logged into the game between April 28 and May 3 of that year. An error resulted in some players receiving the B1-SAL Probe Droid instead, a mistake that was subsequently corrected.
