Blackstarr src

Blackstarr was an enemy of Supergirl.

Early Life

Born to Jewish parents in Poland, Rachel was taken from her mother when they arrived at a concentration camp (in her mind, her mother had let them take her and abandoned her). She managed to amuse the camp commandant so much that she was allowed to live and was taken into his home. Being raised in a Nazi household, combined with her mother's failure to save her, convinced Rachel that the Nazis were right. The camp commandant had been prepared for the fall of Nazi Germany and had arranged false papers for her. These identified Rachel as American and she set off to the United States, where she studied and received her first PH.D. at 18.

Rachel unraveled a mystery that Einstein could only begin to dream of. The very forces of the universe took her, molding her into the being called Blackstarr.

Battle with Supergirl

 Main article: Supergirl: Blackstarr

In the early 1980's, Rachel had made herself the center of a Nazi organization. This caused her to clash with Supergirl and reunited Rachel with her mother. Rachel was torn between her love for her mother and her hatred towards the woman that, in her mind, abandoned her. Supergirl wouldn't let her to harm Mrs. Berkowitz, though, and battled her. Blackstarr teleported Supergirl and herself away to the center of the universe and tried to crush the Girl of Steel with enough cosmic energy to "reduce a planet to dust", but Supergirl managed to turn her gravity-manipulation powers against her, and Blackstarr was apparently torn apart between two black holes.

Crisis on Infinite Earths

Blackstarr reappeared several months later, when the entire universe was falling apart. Supergirl and Superman reluctantly had to work with her.[1]


Blackstarr's powers allowed her to manipulate matter and energy and bend them to her will.


  • This version of Blackstarr, including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths event and later restored following the rebirth of the infinite Multiverse during the Dark Crisis of 2022-2023. Even though other versions of the character may have appeared, this information does not apply to those versions.
