RE-1 was a droid active during a period of galactic conflict involving the Galactic Republic and the Sith Empire.
Star Wars: The Old Republic initially featured RE-1 as a mini-pet companion. It was awarded to players from November 14, 2019, until December 10, 2019, to commemorate the launch of Star Wars Jedi: Fallen Order by Respawn Entertainment. This droid's design drew inspiration from initial, unutilized concept art of the canon droid character BD-1. The game creators collaborated with Respawn to ensure RE-1 reflected BD-1's influence while remaining appropriate for the Old Republic timeline.
