Powers: Doctor Moon has no superhuman abilities but is an expert in gene therapy, psychological conditioning and torture.
Bio: He sold his services to finance his experiments and has taken work for the Joker and the Suicide Squad among others in the past. Pre-Crisis, he was retained by Doctor Cyber after her face was hideously burned, to transfer her brain to a new body, ideally that of Diana Prince/Wonder Woman. When Amanda Waller hired him, he was used to work on Plastique. He was an employee of the Sunderland Corporation and an associate of the Captains of Industry; he oversaw the metagene operation that changed Air Wave into Maser.
Dr. Moon is killed in a fight with Kate Spencer when, during a savage hand-to-hand confrontation, she stabs him with his own scalpel.
