Ougon no Senshi ICZER-ONE

A story set ten years before the events of the Fight! Iczer-1 anime, it details the awakening of Iczer-One as she escapes a Cthulhu spaceship before it is seized by Big Gold. Iczer-One crash-lands on the planet Ishua with no memory of her identity or past. On Ishua, she confronts Magenta, a Cthulhu commander leading the invasion force on that world. A planned second part was never produced.
