Iczer-1

Iczer-1 is a gynoid created by the Cthulhu to serve as their guardian. After Big Gold takes control of the Cthulhu and Iczer-1 is cast out, she reaches Earth and learns of the coming invasion, forcing her to fight the people she was built to protect. To use the giant Iczer Robo, she requires a partner, and the mecha is so closely linked to her that damage to it can affect her own body.
