Phantom Girl (real name Tinya Wazzo) is a fictional comic book superhero who appears in books published by DC Comics. In the Post-Zero Hour continuity, she is known as Apparition, and is a member of the Legion of Super-Heroes in the 30th and 31st centuries. She has the power to turn intangible, allowing her to phase through solid objects as do all other natives of her home planet, Bgztl. Her mother is Winema Wazzo.

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 Bgztllians, Phantom Girl has the ability to phase out of reality to become intangible. Initially appearing along with Triplicate Girl and Saturn Girl in Action Comics #276 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.

Following the Magic Wars, Earth falls under the covert control of the Dominators, and withdraws from the United Planets. Sometime thereafter, Phantom Girl is thought to have been killed in a shuttle accident. In reality, the time sorceress Glorith sends her to the 20th century where she is stripped of her memory of her true identity. She assumes the name Phase and joins the interstellar law enforcement agency, L.E.G.I.O.N.

A few years later, the members of the Dominators' highly classified "Batch SW6" escape captivity. It is first thought that the Batch SW6 are a group of teenage Legionnaire clones, created from samples taken just prior to Ferro Lad's death at the hands of the Sun-Eater. Later, they are revealed to be time-paradox duplicates, every bit as legitimate as their older counterparts. The Batch SW6 version of Tinya Wazzo eventually assumes the codename Apparition.

Phantom Girl has not been a contender in any CBUB matches.
