The Samus Reveal is a technique whereby a beautiful woman in the line of duty, dressed in a suit of some kind that conceals her beautiful womanly attributes and a helmet that conceals her beautiful womanly face, removes the helmet and reveals herself to be a beautiful woman. It was popularized by bounty hunter Samus Aran and named after her. It is occasionally known as the Aran Reveal but this term, though more professional, doesn't quite have the same ring to it.
The technique has also been used to great dramatic effect by Federation policewoman Ysanne Andropath after arresting Jack T. Ladd, Muna Grendy after meeting Spuckler Boach, and Leia Organa after thawing Han Solo from carbonite. Leia's inclusion is sometimes debated, as the others were all wearing the outfits of their occupations, whereas she was in disguise as a bounty hunter named Boushh.
