Biography
Jacqueline Nimball was an engineer employed by a prison. She befriended one of the inmates named Winslow Schott, who was an insane, murderous toy-maker. Winslow took Jacqueline under his wing and made her his protege.

Schott died in prison, and the two had made previous arrangements for her to carry out his wishes after his death. This included terrorizing and tormenting his estranged wife, Mary McGowan, and his adult son, Winn. Jacqueline placed a bomb inside Winslow's coffin, which exploded during the funeral surface.

Later, she created flying robot monkeys that attacked the D.E.O. headquarters, which was where Winn worked, and where Mary had taken up temporary shelter. Mary recognized the logo etching on one of the flying monkeys and traced it back to a toy factory that Jacqueline had set up as her base of operations. She captured Mary and held her inside of a claw device, then sent a message to Winn and his friends at the D.E.O.. Winn, along with Supergirl, Mon-El, Alex Danvers, and J'onn J'onzz went to the factory and fought up against Jacqueline's various bizarre creations. She was ultimately apprehended however, and sent to prison.
