SD was a droid at Ania Solo's junk yard. He served as Ania's security and enforcer, throwing out any unruly customers and protecting the property. He was destroyed by Darth Wredd, who was impersonating Yalta Val, when the imposter attempted to kill Ania and Sauk. Gesaw rats promptly began gnawing on his severed circuits, distracting the fake Val's thugs and allowing the pair to escape.
