Powerful princesses resided on the various Earths of the multiverse, sometimes friends... other times foes... always interesting in their displays of temperment, tenacity, and talents. Among these were Princess Diana of Themyscira and Princess Taia of Thebes, women who fought for the cause of truth and justice since the early years of World War II on parallel planes of existence known as Earth-Two and Earth-S. While Diana as Wonder Woman had a superhuman physique and glorious gadgets, Taia as Ibis the Invincible's true love shared possession of his Ibistick. Thus, Taia was at times able to implement its awesome abilities in a variety of cases in the 1940's, at the same time as had Diana who herself was inspired by a true love in Colonel Steve Trevor. In modern times, Taia would be revived alongside Ibis from another decades long sleep induced by Captain Marvel's arch-foe, Doctor Sivana, who had subjected all of the golden age eras superheroes to a Suspendium-based comatose state. Thus, she was preserved young as was Diana, who had been granted a lengthier lifespan thanks to her Amazonian heritage. Now living in a modern era, both Taia and Ibis remain in retirement from crime fighting, only reappearing once during a Crisis on three Earths instigated by King Kull of Earth-S, which led to the reformation of the Squadron of Justice. However, on this adventure Taia remained behind and thus did not have an opportunity to meet her counterpart Diana of Earth-Two, who with the Justice Society allied with the Squadron of Justice and Earth-One's Justice League.
Another pair of regal royalty were Carol Ferris of Earth-One and Andrea Thomas of Earth-S, selected to be the latest in the line of princesses known as Star Sapphire and Isis, respectively. Each possessed tiara's that while worn provided them tremendous abilities, Sapphire for evil and Isis for good. While their careers were shorter than those of Diana and Taia, they were nonetheless notable for the stir they caused towards those whom they met in battle. At about the same time that Carol Ferris had lost her sapphire to an alien woman who assumed her alter ego, Andrea had acquired her own abilities from that of a previous Isis living centuries ago. Both women retreated to private life after their brief forays into costumed crusading, though their legends lasted longer.
