Kori escaped and stole a space ship to escape to planet Earth, where she met a group of five superheroes and helped form the New Teen Titans. However, far from grateful, Komand'r struck her sister down with the same, much stronger blast of light purple-colored ultraviolet energy and had her restrained for later execution. Against her better judgment, she decided to free Komand'r, who was absorbing more and more ultraviolet energy. While the Psions were distracted, Kori broke free with the newly developed starbolts, which were circular blasts of bright green-colored ultraviolet energy directed from her hands, which were a result of the Psions' experiments. Before the procedure could be completed, Komand'r's Citadel forces attacked the Psion ship to rescue her. The Psions, largely a species of sadistic reptilian scientists, performed a deadly experiment on both of the sisters to see how much ultraviolet energy their Tamranian bodies could absorb until expiring from the excess. When a furious and humiliated Kori killed one of her rapists, Komand'r decided to execute her as punishment, but before getting the chance, the sisters were attacked and captured by the Psions. Komand'r was made her younger sister's ruler and made the most of the bondage with years of horrific servitude and torture. Koriand'r was also never permitted to return to Tamaran, since it would mean the Citadel would devastate the planet for Tamaran's abrogation of the treaty.

They conquered Tamaran with ease, and the surrender conditions included the enslavement of Koriand'r.

Komand'r later betrayed her planet with detailed information about Tamaran's defenses to the the Citadel. Komand'r swore vengeance and joined the Citadel, quickly rising through their ranks to becoming a traitor against her own people and world. Things came to a head during a sparring exercise in which Komand'r attempted to kill her sister. Komand'r's rivalry continued and intensified when the siblings were sent for combat training with the Warlords of Okaara. Komand'r's rage grew inward, and whenever she could, her hatred for her planet was focused on her hapless sister. All of her queenly privileges, honors, and celebration were later given to her younger sister, Koriand'r. Komand'r grew up hated by the Tamaran population, who denied her birthright and refused to allow her to be the next Princess of Tamaran. To make matters worse, Komand'r had been stricken with a childhood illness that left her unable to harness ultraviolet light to fly as most Tamaraneans did. Though she was in no way at fault for what had happened Komand'r was for all time inextricably linked with that terrible day.

On the day she was born the Citadel Empire attacked and destroyed the western Tamaranean city of Kysarr, killing three thousand citizens in her name. The first princess born in over a hundred years, she should have been courted and showered with honors. Komand'r was born the eldest child of Tamaran's royal family.
