Origin
Tamaran
Koriand'r, Starfire's given name, is a princess of the fictional planet Tamaran in the Vega system, and was in line to rule the planet as queen. Komand'r (also known as Blackfire), her older sister, developed a bitter rivalry with her after suffering a disease in infancy that robbed her of the ability to harness solar energy to allow her to fly, and by extension, her right to the throne. This rivalry continued and intensified when the siblings were sent for warrior training with the Warlords of Okaara. Things came to a head during a sparring exercise in which Komand'r attempted to kill her sister. As a result, Komand'r was expelled and she swore vengeance. That revenge came in a plot where Komand'r betrayed her planet by supplying detailed information about Tamaran's defenses to their enemies, the Citadel. They conquered Tamaran with ease, and the surrender conditions included the enslavement of Koriand'r, who was never permitted to return, since that would mean the Citadel would devastate the planet for abrogating the treaty. To her horror, Koriand'r learned that Komand'r was her master; her own older sister made the most of her sibling's years of horrific servitude. When Koriand'r killed one of her captors, Komand'r decided to execute her as punishment, but the sisters were attacked and captured by the Psions, a group of sadistic alien scientists. While performing deadly experiments on the sisters, the Psion were attacked by Komand'r's forces. Koriand'r broke free using her newly developed starbolts, destructive blasts of ultraviolet energy which were a result of the experiment. She freed Komand'r, who was still absorbing more amounts of ultraviolet energy. Far from grateful, Komand'r struck her sister with the same, but with more intensity and power and had her restrained for later execution. Koriand'r escaped by stealing a spacecraft to flee to the nearest planet, Earth, where she met the first Robin and his compatriots; she joined them in forming the Teen Titans. She became a charter member of this team and remained a member for years, finding work as a professional model using the name Kory Anders.
