A Queen Mulano resided on the 4th dimensional world of Duomal which Anton Unreal visited, wherein the individuals there had not yet developed this phasing power that Tinya's people gained. Mulano first encountered an individual from adjacent third dimensional world of Earth-Two and aided her in ending a long brutal war between the nations of Thrule and Arren was Zatara. When he used his abilities to bring together the leaders of these respective countries to rule over a united planet now names Duomal. Milano's counterpart on the parallel planet of Bgztl was Winema Wazzo, herself a politician opposed to her daughter Tanya's superheroine career.
Tinya as Phantom Girl quickly decided in her mid-teen years to become the superheroine known as Phantom Girl, and journeyed to the third dimensional world of Earth-One in order to join the Legion of Super-heroes in her native 30th century. As one of the first members, she served with distinction and even became a part of the Legion Espionage Squad which handled covert missions for the Legion. Wazzo developed feelings for Ultra Boy aka Jo Nah. Tress would reappear after her adventure with her fellow Holliday Girls when they used their immaterial abilities once more to assist Wonder Woman. In her place during the 30th Century on Earth-Two would be another former resident of the Fourth Dimension, a replica of Steve Trevor who accompanied Dorothy "Dot" Lord aka the future Wonder Woman into that era.
