Known alternatively as "Myriad" later on, Sasha Green was once employed at LexCorp as a martial arts instructor for training Lex Luthor himself. One day, while training Luthor in martial arts, she beat Luthor in front of Supergirl and Lois Lane and they laughed at him. Because of the embarrassment, Luthor secretly killed Sasha Green in her locker room, framed a janitor for her death and dumped her body at a LexSan landfill. Her first appearance dating back as "Superman Vol 2 #77" in March, 1993.
