Candy Barts commands the warship *Queen Fuji*, Earth's last defense against the alien forces of Neos Gold. At 25 years old, her calm and composed nature allows her to maintain clarity under pressure and make clear decisions more efficiently than others in stressful situations.

She develops professional respect for the gynoid warrior Iczer-3, acknowledging Iczer-3's combat prowess while voicing concern for her safety. A romantic relationship gradually forms between Candy and Rob Onwa, the *Queen Fuji*'s chief engineer. This relationship evolves further within the radio drama novelization of the sequel *Iczelion*, explicitly identifying Candy as Rob's girlfriend. In this continuation, she frequently expresses anxiety over Earth's survival amidst ongoing conflict and remains protective of Iczer-3's well-being.

Her leadership extends beyond tactical command; Candy takes pride in the *Queen Fuji*'s capabilities and her crew's professionalism.
