Iczer One is a gynoid created by the Cthulhu also known as Cthulwulf to be their guardian. However when the Cthulhu were taken over by Big Gold Iczer One was jettisoned. She arrived on Earth and somehow got wind of the coming invasion by the Cthulhu now under Big Golds command. She was therefore forced to defend the Earth against those she was created to protect. To do this she needed a partner to help her use the Iczer Robo a giant fighting mecha which is somehow connected to her a connection so profound that when Iczer Robos arm was cut off Iczer One lost the use of her own corresponding arm.
