The depicted subject bears the likeness of Dream Girl from the DC Comics; however, the DCAU character was never named on-screen, or otherwise. The title of this article is conjecture based on the character's likeness.
In the comics, Dream Girl is Nura Nal from the planet Naltor. Like all her planet's people, she possesses precognitive abilities. She saw in a dream the deaths of several Legionnaires and warned them. She earned a membership, though later it was revealed that she saw robot duplicates killed, not the actual Legionnaires.
