The LU-20 Builder was a type of small labor droid available during the Cold War between the Galactic Republic and the Sith Empire.

Behind the scenesEdit

The LU-20 Builder appears in the video game Star Wars: The Old Republic as a pet. It was a reward for players of the game Lord of Ultima as part of the cross-promotion between Electronic Arts's free-to-play games; players of Lord of Ultima who created an account in The Old Republic by April 1, 2013 received the pet.
