Trivia

 * From the Justice League Unlimited incarnation, only Wonder Woman, Supergirl, and Hawkgirl make their appearance in this episode. Wonder Woman and Hawkgirl had already appeared previously in "Justice is Forever".
 * The Gorgon sisters all appear face to face with Wonder Woman, Supergirl, and Hawkgirl (all of whom are blindfolded so that they can't be turned to stone from the eyes of the monsters).
 * Eventually, the only way to stop the Gorgons is to cover your face with a mirror or anything silver and even reflective.
