Big String was a male amphibious alien who lived during the reign of the Galactic Empire as a crime boss in a fortress he constructed on the Inner Rim planet Amethia Prime. Some time later, an individual hired Chanath Cha, a bounty hunter, to destroy Big String's fortress and apprehend the crime boss. Cha did, and Big String was forced to flee. Cha caught up with him, however, and grabbed onto him and flew to cloud-level. Cha received a call from Galactic Emperor Sheev Palpatine, so she dropped Big String from the tremendous height.
