Like all natives of the planet Bgztl, Phantom Girl has the ability to turn intangible. Bgztl either exists in or is connected with the extra-dimensional space known as the Phantom Zone. She has demonstrated the ability to phase with split second timing, and is also capable of phasing certain parts of her body selectively. While phased, she is immune to physical harm, can maneuver through solid objects and fly under her own power. She is also immune to most energy blasts and radiation, though writers have been inconsistent regarding her vulnerability to attacks utilizing the air. She has additionally demonstrated the ability to disrupt the workings of electronic devices by moving through them while phased.
