In the original pre-Crisis on Infinite Earths continuity, Phantom Girl is the fifth member to join the Legion and is a native of Bgztl, a planet that exists in the 4th Dimension. Like other Bgztlians, Phantom Girl has the ability to phase out of reality to become intangible. Initially appearing along with Triplicate Girl and Saturn Girl in the story "Supergirl's Three Super Girl-Friends", her first costume consisted of white tights and a white cape with a stylized P on the chest. Phantom Girl's powers serve her well as member of the Legion's Espionage Squad, and she is involved romantically with fellow Legionnaire Ultra Boy for many years. In this continuity, she has a brother, Gmya Wazzo.
