Starfire

Princess Koriand'r was the youngest daughter born to the First House of Tamaran. She lived a happy and peaceful life until her home planet was attacked by the alien conquerers, the Citadel, who operated under the orders of the evil Dominators. The Citadel killed Kori's family, with the exception of her older sister Komand'r, and enslaved the entire population of Tamaran, including Kori. They appointed Komand'r as the leader of Tamaran, seeking to use her as a figurehead to appease the planet's people. However, in an attempt to take away the people of Tamaran's will to fight back, they forced Komand'r to publicly banish her sister from the planet.

Kori was taken by the Citadel and was the subject of numerous painful experiments. She was discarded in Takron, a savage prison populated by aliens from the various planets the Citadel had conquered. The Citadel suspected she would perish quickly, but she survived motivated by her rage. After lashing out against a Citadelian guard, Kori projected huge amounts of energy from her body, and realized the experiments conducted on her had unintentionally given her incredible powers. She was restrained and further experimented on, enslaved and drugged to keep her compliant.

Eventually, Kori was forced to work on a slave ship called the S.S. Starfire, where she met Orn, a rebel Citadelian who had been enslaved by his own people. He showed Kori kindness and love, and smuggled food for her. She began training in secret with Orn, and eventually managed to empower the slaves on her ship to overthrow their captors, leading a rebellion that freed the aliens from their captors. Kori took control of the ship she had been enslaved upon, liberated the people of Tamaran, and became known throughout the galaxy as Starfire.
