Doctor Chelli Aphra was an archaeologist recruited by Darth Vader after the Battle of Yavin. Aphra, along with her assassin droid companions, 0-0-0 (Triple-Zero) and BT-1 (Beetee), fulfilled several missions for the Sith Lord before falling out of his favor, and after faking her own death, continued to roam the galaxy with the two droids.
