OVA
Description
Based on the ancient wish-granting machine invoked by Sir Violet's despair, Iczer-One emerged as the embodiment of "Conscience," created alongside Big Gold as "Desire." Designed as the Cthulhu's guardian and future leader, she rejected their fascist corruption under Big Gold and fled to Earth. Her physical form is a humanoid female with blonde hair, pointed ears, and a pink-and-white combat leotard. She wields extensive biomechanical capabilities, including teleportation, energy projection (knuckle beams, light sabers), dimensional shifting, and flight. Her physiology features a symbiotic link to the giant mecha Iczer Robo, her "other self," where damage to the mecha manifests as corresponding injuries on her body.

Her core mission became defending Earth from the invading Cthulhu. To unleash Iczer Robo's full combat potential, she required synchronization with a human partner fueled by intense emotions like rage and grief. She selected Japanese schoolgirl Nagisa Kano. Their partnership faced initial resistance due to Nagisa's trauma, but solidified through shared battles against parasitic Vedim and Cthulhu commanders like Cobalt. A critical confrontation arose against Iczer-2, a burgundy-haired android counterpart created by Big Gold to eliminate her. Iczer-One's compassion caused hesitation against this "sister," nearly leading to defeat. The conflict culminated when Iczer-2 abducted and mentally enslaved Nagisa, forcing Iczer-One to kill her partner to prevent subversion. Nagisa's death triggered their ultimate synchronization, merging their spirits and granting Iczer-One divine-level power.

In her final battle, she destroyed Iczer-2—who expressed longing for a partner like Nagisa—and Big Gold. Leveraging the wish-granting machine's power and her synchronized state, she reversed all Cthulhu-inflicted damage, restoring Earth and erasing human memory of the invasion. Her story concluded as she departed Earth aboard a Cthulhu vessel to seek a new homeworld, briefly encountering a now-unknowing Nagisa. Expanded media reinforced her role as the counterforce to Big Gold's embodiment of desire. While sequels introduced new protagonists, they did not substantially alter Iczer-One's established arc or significance within her original narrative.
