Synara San is a Mirialan, the same species as Jedi Luminara Unduli and Barriss Offee, first seen in Star Wars: Episode II - Attack of the Clones (2002). Earlier designs had her sporting green skin like the aforementioned Jedi rather than a shade of purple. Like all of Kragan Gor's pirates, she wears pieces of Imperial armor, in this case the boots and belt of a Scout Trooper.
