Originally Phase was Tinya Wazzo transported to the past and given amnesia by Glorith. Later via retcon she was revealed to be Tinya's cousin Enya Wazzo and Tinya was reunited with Ultra Boy in the 30th Century. Post-Zero Hour Phase was revealed to be one of Tinya's other two selves.
In the Enya version Enya was born in the 30th Century and was the cousin of Tinya Wazzo, Phantom Girl of the Legion of Super-Heroes. The temporal machinations of Glorith sent her back in time in an explosion that killed her cousin. She arrived in the 20th Century an amnesiac, where she found a new identity as an officer of L.E.G.I.O.N..
During Zero Hour the original Legion of Super-Heroes, along with the entire future Enya came from was destroyed from existence and replaced by a new one. Rather than being Tinya's cousin, Tinya was part Carggite (a race with the natural ability to divide into three bodies) and Phase was revealed to be one of her other selves who had been separated at birth after her first triplication. A time-displacer had sent her back to the 20th Century to help her avoid danger. While Tinya was stranded in the past at one point, the two of them met and merged into a single being with all of the combined memories of both.
- Phasing: Enya Wazzo possesses the ability to pass through solid matter by passing her atoms through the spaces between the atoms of the object through which she was moving.
- Carggite Duplication: Enya inherited her father's Carggite physiology and has the ability to split into three versions of herself. Until such time as Enya and her other two selves are reintroduced to one another, she cannot use this ability.
There are 3 iterations of Phase due to various retcons. First she was presented as Tinya Wazzo aka Phantom Girl with amnesia. Then she was revealed to be Tinya's cousin Enya. Then it was revealed that the Post-Zero Hour Tinya was half-Carggite and that her father sold Tinya's two duplicates to the Luck Lords and Phase was one of these two duplicates.
