Galatea was a clone of the Argoan Supergirl. Much like Doomsday, she was created by Project Cadmus as a contingency in case Superman and other members of the Justice League ever went rogue. She was cloned from a tissue sample of Kara In-Ze which was collected by Prof. Emil Hamilton when he performed surgery on the girl. She was artificially aged to her physical prime and brainwashed by Cadmus to act as essentially their assassin to deal with elements Cadmus deemed rogue and a potential threat to US national security.
