Starfire
Species: Tamaranean
Enemies: Blackfire, The Citadel
Known technically as Koriand’r, she is actually the Princess of Tamaran. The Starfire codename came later. Why did she leave her homeworld? She was in line to be Queen, but she and her sister Komand’r (aka Blackfire) developed a bitter rivalry. It stems from when Blackfire was born. She suffered from a disease that prevented her from having the ability to harness solar energy. Yet Koriand’r was not born this way. The “Starfire” power is what allows their family to remain on the throne in Tamaran. Thus, Blackfire had no claim to the throne. During a warrior training exercise, Komand’r attempted to kill Koriand’r.
That led to Komand’r being expelled from her homeworld, making her swear to take her sister down. She went to Tamaran’s bitter enemy, the Citadel, and gave them key defense plans from her planet. The Citadel conquered the Tamaraneans easily. As part of their surrender, Kori was forced into enslavement which resulted in her sister being her master, but Kori later escaped to Earth. That is where she managed to develop even more power due to our Sun’s power. Now, Kori is able to take down nearly any galactic threat with the literal power of a star. Teaming with the Teen Titans, Starfire is a heavy-hitter in every story.
