Dr. Carolyn "Callie" Llewellyn was an arcanobiologist who once had a relationship with Clark Kent.

She was brought to Kazakhstan by its government after they had found a monstrous, but dormant, creature known as Subjekt-17 in an abandoned Soviet laboratory. She was charged with removing it safely, but it escaped. Clark Kent, who was en route to Kazakhstan at the time to cover her story, heard her cries for help and arrived as Superman to battle the beast.
